General Description
Introduction
WARNING
CAUTION
This manual covers optional on-board, integrated, chilled
water pump package available on all Daikin Model AGZ-D
(REV 0A) chillers. Factory-installed pump packages provide
important benefits:
• Greatly simplify the chilled water system design and
installation
• Provide installation savings by reducing field piping,
wiring and control costs
• Save valuable floor space inside the building
• Reduce project engineering content
• Greatly reduce pump operating cost with the optional
variable flow pump Variable Frequency Drive (VFD)
Standard Components
Single Pump (Model 4380) is a single spring inside seal,
vertical, in-line, radially split-case pump, serviceable without
breaking pipe connections. The motor and pump rotating
assembly can be serviced without removing the pump casing
from the line.
Dual Pumps in a Single Casting (Model 4392) single-spring
inside-seal vertical, in-line, radially split-case pumps, mounted
in a common casing with a common inlet connection and
outlet connection and including a flapper valve to prevent
recirculation when only one pump is operating. An isolation
valve is included that allows one pump to operate when the
other is removed. The pumps are designed for duty/standby,
not parallel operation. All information and performance curves
for the single pump arrangement (Model 4380) can be used for
the dual pump arrangement (Model 4392.)

Optional Variable Flow VFD
The operating cost savings resulting from using variable
chilled water flow via a pump VFD has been well known for
many years. In the past, however, its usage has been somewhat
limited by the cost and uncertainty of field installing the
required system pressure differential sensors.
Daikin Applied can now offer a variable chilled water flow
system, completely self-contained within the pump package,
by simply ordering the optional pump VFD-no external
sensors required.
Including sensorless operation, there are four operating modes
available with the optional factory-installed variable flow
VFD:
allow control of the pump speed to optimize chilled
water flow with respect to water system pressure.
External pressure sensors are not required, eliminating
design and installation effort. The unit is factoryconfigured for this mode.
2 BAS Input: The pump speed will be controlled
according to the voltage level from a BAS input signal.
of the pump at a constant speed selected on the VFD
control panel. Among other things, this mode allows
selecting a pump speed to match the actual system curve.
4 Remote Sensor Control: The VFD is wired to pressure
sensors mounted in the chilled water piping system. This
is the standard VFD control when a sensorless VFD is
not used.
Pump Description
• Pump casing is cast iron.
• The casing suction and discharge connections are the
same size and have tapped seal vent and pressure gauge
connections.
• The mechanical seal is single-spring inside type with
carbon against silicon carbide faces. EPDM elastomer
with stainless steel and hardware are provided.
• Impellers are bronze, trimmed to design conditions and
then balanced.
• The shaft sleeve is bronze extending the full length of
the seal area.

Selection Procedures
Selection Procedures
Selection Procedure
This section provides material to make pump selections. Your
Daikin Applied sales representative can make computerized
selections and provide pricing. The AGZ-D model size, the
chilled water flow, and the total dynamic external system head
are required to select a pump package.
AGZ Model Size
The AGZ-D model size is determined by the selection program
or selected from the current version of the Daikin Applied
catalog available from your local sales representative or
www.DaikinApplied.com.
Chilled Water Flow
The chilled water flow will either be specified or determined
from the AGZ selection program.
Total Dynamic System Head
The total system dynamic head is the sum of three
components:
1 Internal pump package losses from piping, valves and
fittings from Table 1
2 Evaporator pressure drop from the selection program or
from curves on page 15
3 External system pressure drop as determined by the
system designer.
For systems using a glycol solution:
"For the internal package pressure drop, use Table 1 values.
Glycol has no significant impact.
"For the evaporator pressure drop, the Daikin Applied
selection program includes an automatic correction factor. If
the pressure drop is determined from the pressure drop curves,
use the correction factors from Tab le 2 to calculate the water
pressure drop for glycol. Do not use uncorrected table values
for the evaporator.
"The external system pressure drop must also account for
glycol use.

A family of pump sizes has been pre-selected for groups of
AGZ units and shown in Table 3.
Selection Examples
Select: a pump for an AGZ 025-D with 65 gpm of water flow
at a 90 ft external head, dual pumps. From Tab le 1., the
internal pump package pressure drop is 3.7 ft.
From the pressure drop curves on page 15, the evaporator
pressure drop is 9.4 ft.

External90.0
Total Head103.1
Using the required flow and total system head, select the best
pump from the table. Flow values are shown for minimum,
nominal, and near-maximum flow rates for each AGZ size. For
flow rates falling between these values, check the pump
selection for the higher and lower flow. The impeller will be
trimmed for specific job conditions after order placement.
Impeller Size (in.)
From Table 3., select a dual 2 x 2 x 6 pump, 3600 rpm, 7.5 hp.
Although a 5 hp pump is adequate at design conditions, a 7.5
hp pump will provide non-overloading characteristics.

Table 3: AGZ-D Unit/Pump Combinations Continued
Note: Some unit gpm and head combination do not have a valid selection and are absent from the table.
This section provides additional information on optional pump
packages factory-mounted on Daikin Model AGZ-D (REV
0A) scroll compressor chillers. The current chiller installation,
operating, and maintenance manuals are available at
www.DaikinApplied.com.
Inspection
When the equipment is received, carefully check all items
against the bill of lading to check for a complete shipment.
Check all units for damage upon arrival. All shipping damage
must be reported to the carrier and a claim must be filed with
the carrier. Check the unit's serial plate before unloading the
unit to be sure that it agrees with the power supply available.
Physical damage to unit after acceptance is not the
responsibility of Daikin Applied.
Note: Installation and maintenance are to be performed only
by qualified personnel who are familiar with local codes and
regulations, and experienced with this type of equipment.
Handling and Rigging
Follow the directions in IM 1100 for locating, handling and
rigging the unit. The addition of the optional pump package
does not change installation procedure. However, vibration
isolator selection and location, lifting and operating weights,
dimensions, and electrical data will differ from units without a
pump package. Refer to dimension drawings for center-ofgravity locations.
Field Water Piping
Piping design must be provided by a qualified Architect or
Systems HVAC Design Engineer familiar with piping design,
as well as local codes and regulations. The manufacturer
recommendations are to be used as a general guide, but do not
replace system design by a qualified professional. All field
piping, wiring, and procedures must be performed in
accordance with ASHRAE, EPA, and industry standards.
Use best practice for piping design with a minimum number of
bends and changes in elevation to keep system cost down and
performance up. See AGZ-D installation manual, IM 1100, for
general unit piping information.
The chilled water piping contains vent and drain connections
as well as taps for inlet and outlet pressure gauges. Install a
manual or automatic vent and a drain valve. Install a single,
valved pressure gauge as shown in the chiller unit installation
manual. The unit inlet and outlet connections are marked. It is
prudent to double check the unit dimension drawing to confirm
the connections.
The inlet guide and the outlet triple duty valve are shipped
separately to protect them from shipping damage. Install on
the unit and support as necessary. Support the chilled water
piping independently from the unit.
Flush the system water piping thoroughly before making
connections to the unit evaporator.
System Water Volume
It is important to have adequate water volume in the system to
provide an opportunity for the chiller to sense a load change,
adjust to the change and stabilize. As the expected load change
becomes more rapid, a greater water volume is needed. The
system water volume is the total amount of water in the
evaporator, air handling products and associated piping. If the
water volume is too low, operational problems can occur
including rapid compressor cycling, rapid loading and
unloading of compressors, erratic refrigerant flow in the
chiller, improper motor cooling, shortened equipment life and
other undesirable occurrences.
For normal comfort cooling where the cooling load changes
relatively slowly, we recommend a minimum system volume
in gallons of 2 to 3 times the flow rate (gpm). For example, if
the design chiller flow rate is 350 gpm, we recommend a
minimum system volume of 700 to 1050 gallons.
Since there are many other factors that can influence
performance, systems can successfully operate below these
suggestions. However, as the water volume decreases below
these suggestions, the possibility of problems increases.
Freeze Protection
In installations where the unit is subject to sub-freezing
temperatures, some method of preventing pipe and component
freezing and subsequent damage is required. The pump will
start on a signal from the chiller controller when either the
chilled water leaving or entering temperature reaches the
chiller freeze point setting to help prevent freeze up. If
constant chilled water circulation is not possible or desired,
one or more of the following procedures must be used:
• Drain the outdoor portion of the system and cap with a
nitrogen charge.
• Heat trace all outdoor components.
• Add sufficient anti-freeze to prevent freezing.
Note: the evaporator is equipped with a water heater to help
protect from freezing. This heater does not protect the pump
package piping or components.
Adding of a concentration of a glycol anti-freeze with a freeze
point 10°F below the lowest expected outdoor temperature will
result in decreased capacity and increased pressure drop in the
chiller. AGZ units are selected to provide the required
capacity with the fluid specified when selected.
Temporary Strainer
The suction guide strainer contains a tempory strainer that
must be removed after startup. See page 81 in the Startup and
Shutdown section. for complete instructions.
.
CAUTION
Do not use automotive grade antifreezes as it contains inhibitors harmful to chilled water systems.
Use only glycols designated for use in building cooling systems

Operating Weights & Vibration Isolators
Vibration isolators are recommended for all roof-mounted
installations or wherever vibration transmission is a
consideration. Initially install the unit on shims or blocks at the
"free height" of the isolator. When all piping, wiring, flushing,
charging, etc. is complete, adjust the springs upward to load
them and to provide clearance to free the blocks, which are
then removed.
Table 6: Operating and Mounting Weights
A LUM INUM
COPPER FIN
Installation of spring isolators requires flexible pipe
connections and at least three feet of conduit flex tie-ins.
Support piping and conduit independently from the unit to not
stress connections. Mounting locations are on the unit
dimension drawings beginning on page 23. Isolator selections
are different for AGZ-D units with a pump package than those
without one.

Determining Flow Rate - Valve In Full Open Position
Measure and record the differential pressure across the valve
using a CBDM- 135/60 meter, or pressure gauges with PMP
adapters.
Safety glasses should be used and the probe should not be left
inserted into fittings for prolonged periods of time as leakage
Locate Pressure Differential on left hand side of Performance
Curve (Figure 9) and extend line horizontally across to valve
size being used. Drop line vertically down and read flow rate
from bottom of chart.
Determining Flow Rate - Valve In Throttled Position
Record the size of the valve and stem position using the Flow
Indicator Scale. Calculate percentage of valve opening
referring to table below:
Table 11: Valve Size and Number of Rings
Number of Rings
(valve full open)
Measure and record the differential pressure across the valve
in the throttled position. Project a line vertically up to intersect
with the Valve Curve and from this point project line
horizontally across to the left of the chart and record the
percentage of maximum flow rate.
On the Performance Curve (Figure 9) locate the differential
pressure obtained above and project a line horizontally across
to intercept with Valve Performance Curve. Drop a line
vertically down to read the flow rate at the bottom of the chart.
IM 1110-121
CAUTION
from the PMP may occur when probe is removed.
Valve Size2 1/2345681012
556910121828
To calculate flow rate of valve in the throttled position,
multiply the flow rate by the percentage flow rate divided by
100.
Example:
• Valve size 4 inch.
• Differential Pressure is 5.4 ft. (1.65 m).
• Number of rings open = 3. Therefore: 3 rings ÷ 6 rings x
100 = 50% throttled.
From the Performance Curve (Figure 9), a 4 inch, valve
with 5.4 ft. pressure drop (1.65 m) represents a flow of 400
USgpm (25.2 l/s).
From Flow Characteristic Curve (Figure 10)., a 4 inch
valve 50% open, represents 34% of maximum flow.
Approximate flow of a 4 inch valve, with a 5.4 ft. (1.65 m)
pressure drop when 50% throttled is:
400 x 34/100 = 136USgpm
or in metric, 25.2 x 34100 = 8.57l/s
Note: To prevent premature valve failure it is not
recommended that the valve operate in the throttled position
with more than 25 ft. pressure differential. Instead the pump
impeller should be trimmed or valves located elsewhere in the
system be used to partially throttle the flow.
Flow Indicator Scale
The valve stem with its grooved
rings and positioning sleeve
indicates the throttled position of
the valve. The quarter turn
graduations on the sleeve, with the
scribed line on the stem provides
for approximate flow measurement.
Note: The valve is shipped in the closed position. The
indicator on the plastic sleeve is aligned with the vertical
scribed line on the stem.

Electrical Information
Note: Incoming power and run signals are factory wired.
Note: Single pump panels have only Pump #1
and have a single run signal from the main box.
Electrical Information
Figure 17: Pump Panel Wiring Diagram with Dual Pumps/Dual Control
Power Wiring
As standard, power to the pump package control panel is
factory wired from the chiller electrical panel. When the
optional chiller multi-point power wiring is specified, the
pump power originates from power circuit #1.
There is an option for field power wiring the pumps in lieu of
factory wiring. In this case the necessary electrical data begins
in Table 11 on page 40. In all cases, field power wiring
connections are made to L1, L2, L3 and GND on the pump
panel circuit breaker.
Power wiring to the chiller unit will be as shown in the chiller
catalog and installation manual.
Control Wiring
Control wiring to the chiller unit will be as shown in the chiller
catalog and installation manual except that the flow switch and
pump output signals shown as field wiring will be factory
wired.
Control wiring to start and stop the pump(s) is always factory
wired from the chiller electric panel to the pump package.
Dual pumps have two output signals and single pumps have
one.
The pump panel schematic, Figure 28, shows the standard dual
pump arrangement. Optionally a VFD can be substituted for
the contacts shown. A VFD line reactor can also be added.
A single pump can be ordered, in which case only one run
signal is factory wired in.
VFD Option, the VFD will require field wiring if the optional
BAS control is used or if the VFD is wired to field-mounted
differential switches. The pump BAS protocol will be the same
as specified for the chiller unit. The standard sensorless
arrangement does not require field wiring.
For BAS connection, use RS485 and wire to terminals 68 (+)
and 69 (-) for Modbus, FLN or Metasys protocols. The
terminals are located in the lower-right corner of the pumpmounted VFD enclosure under the keypad.

Pump Operation
Pump Operation
Pump Start Control (MicroTech® III)
The standard arrangement is for the MicroTech III unit
controller pump output signal to automatically start and stop
the pump(s). The specific starting method is determined by the
Evap Pump Control setpoint. This setting allows the following
configurations:
• #1 only - Pump A will always be used
• #2 only - Pump B will always be used
• Auto - The primary pump is the one with the least run hours;
the other is used as a backup
• #1 Primary - Pump A used normally; pump B is backup
• #2 Primary - Pump B used normally; pump A is backup
#1 Only or #2 Only
Selecting [#1 only] or [#2 only] will run only the pump
selected; the other is unavailable. This mode is useful for
running only one pump if the other is out of service. [#1 only]
is the factory default setting when there is only one pump on
the pump package.
Primary/Standby Pump Staging
The pump designated as primary will start first. If the
evaporator state is START for a time greater than the
RECIRCULATE TIMEOUT setpoint and there is no flow, then
the primary pump will be deenergized and the standby pump
will start. When the evaporator is in the RUN state, if flow is
lost for more than half of the FLOW PROOF setpoint value,
the primary pump will shut off and the standby pump will
start. Once the standby pump is started, the FLOW LOSS
alarm logic will apply if flow cannot be established in the
evaporator START state, or if flow is lost in the
EVAPORATOR RUN state.
Auto Control
AUTO pump control is the factory default on two-pump units;
the primary/standby logic above is in effect. When the
evaporator is not in the RUN state, the run hours of the pumps
will be compared. The pump with the least hours will be
designated as the primary at this time.
Optional Local Control at Pump Panel
This control method can be selected at time of order placement
and provides for one start output from the MicroTech III unit
controller to start or stop pumps and two non-VFD pumps.
Pump operation is controlled by a selector switch located on
the door of the pump control panel. Pump #1 and Pump #2 will
run the respective pump exclusively, with no duty/standby
feature. The Auto position will alternate pump selection
through an alternating relay, changing pump with each start.
This option does not have the desirable automatic duty/standby
attribute normally associated with dual pumps. In case of a
pump failure, the second pump must be started manually on
the selector switch.
Pump Operating Control
Constant Flow
The pumps will run at constant speed and will start and stop
automatically with the chiller unit. When the chiller is enabled
to run by having its MicroTech III unit controller in the Auto
state or by a signal from a BAS (not necessarily with
compressors running based on availability of a cooling load),
the pump panel will receive a signal to start. When there is
sufficient flow to close the flow switch within a timed period
(recirc timer), a proof-of-flow signal is sent to the chiller and
the pump is in the Run state. If there is a call for cooling based
on the chilled water temperature, the chiller will commence its
compressor startup procedure. If there is no call for cooling,
the chiller will be on stand-by, waiting for load.
If the flow switch does not see flow, the pump remains in the
Start state until flow is established, at which time the pump
will be in the Run state. Flow is recognized when the flow
switch indicates flow for longer than the recir timer setpoint.
The Run state is a control condition established by satisfying
certain conditions. The Start state means that a digital signal
has been sent to the pump for it to start running.
If say, a chilled water valve is closed, the pump may receive a
Start signal and will run dead-headed but not actually be in the
Run state as defined by the controller. No alarm is given in
this condition. When the valve is opened, the flow switch will
see flow, will signal this to the chiller controller, and the pump
will go to the official Run state.
When starting the chiller, it is prudent to be sure there is flow
so the chiller compressors will be able to start based on a call
for cooling due to high chilled water temperature. Observing
water pressure gauges can confirm flow.
Flow interruption will open the flow switch, sending a signal
to the chiller to shut down and also de-energize the pump. If
the chiller is turned off, the pump will shut off after a timed
period to allow water circulation during refrigerant
pumpdown.
Operation of the evaporator pump is controlled by the Pump
Transition diagram in Figure 18. The pump will start on a
signal from the chiller controller when either the chilled water
leaving or entering temperature reaches the chiller freeze point
setting to help prevent freeze up.

Variable Flow
There are four possible pump operating modes when the pump
package is equipped with the variable frequency drive (VFD)
option:
1 Sensorless Pressure Control
2 BAS Control
3 Remote Sensor Control
4 Locally SElected Constant Speed Control
Sensorless Pressure Control is the factory default setting.
Sensorless Pressure Control
Speed and pressure is adjusted to match the system load. The
control curve is designed to replicate sensor positions at
varying distances from the pump. Sensorless control is an
innovative concept in circulating pumps. Pump performance
and characteristic curves for ten different speeds are embedded
in the memory of the speed controller during manufacture.
This data includes power, pressure and flow across the flow
range of the pump.
These measurements enable the pump to continuously identify
the head and flow at any point in time, giving accurate
pressure control without the need for external feedback
signals. Patented software technology within the controller
ensures trouble-free operation in all conditions.
reduced, the pump automatically reduces the head developed
according to the pre-set control curve. It is often found that
using a remote differential pressure sensor to sense the
pressure across a remote load could theoretically result in
loads close to the pump being under-pumped. The situation
would be where the load at a loop extremity is satisfied and the
control valve closes while a load close to the pump needs full
flow. The probability of this occurring is remote but it is
possible. One answer to this is to move the sensor closer to the
pump (two-thirds out in the system is a popular
recommendation) although physically re-positioning the
sensor at commissioning stage can be a costly exercise. With
Sensorless pump control it is possible to replicate the moving
of a sensor by adjusting the head setting 'Hmin'.
Figure 19: Pump Control Curve
Incorporating the pump's hydraulic data into the controller and
removing sensors results in true integration of all components
and removes the risk of remote sensor failure.
The default control mode for Sensorless pumps 'Quadratic
Pressure Control' where the controller is set to control the
speed according to a 'control curve' between max and min flow
(seeFigure 19). Fitting a differential pressure sensor at the
most remote load, across the supply piping and return piping
encompassing the valve and coil set, is generally the best
installation scheme for energy efficiency.
Sensorless control can replicate this control without the need
for the remote sensor. As the flow required by the system is
IM 1110-147
BAS Control
The pump will speed up or slow down based on an input from
the BAS. The pump control protocol is the same as ordered for
the chiller unit.
Remote Sensor Control
The VFD is wired to pressure differential switch(s) mounted in
the chilled water piping system. This is the standard VFD
control when a sensorless VFD is not used

Warnings and Alarms
A warning or an alarm is signaled by the relevant LED on the
front of the GLCP and indicated by a code on the display. A
warning remains active until its cause is no longer present.
Under certain circumstances operation of the pump may still
be continued. Warning messages may be critical, but are not
necessarily so. Warnings should be attended to ASAP as they
can revert to an Alarm-shutting down the unit.
Viewing Warnings & Alarms
To view the warning or alarm details, press the Alarm Log key
in the middle of the GLCP. Press the ? or ? key to go to the
Alarm Log line and press OK. Navigate to the appropriate
alarm number, press OK and view the alarm description,
number and date-time stamp. A detailed description with some
corrective measures is below in the section titled Warning/
Fault Messages.
Resetting Alarms
In the event of an alarm, the inverter will have tripped. Alarms
must be reset to restart operation once their cause has been
rectified. In many cases the auto reset function will restart the
pump. Alternatively the [RESET] button on the control panel
can be pressed.
NOTE: After a manual reset using the [RESET] button on the
control panel, the [AUTO ON] button must be pressed to
restart the pump.
If an alarm cannot be reset, the reason may be that its cause
has not been rectified, or the alarm is trip-locked (see also
table on following page).
Alarms that are trip-locked offer additional protection, means
that the mains supply must be switched off before the alarm
can be reset. After being switched back on, the inverter is no
longer blocked and may be reset as described above once the
cause has been rectified.
Alarms that are not trip-locked can also be reset using the
automatic reset function Reset Mode (Note: automatic wakeup is possible!)
Selected warning and fault messages follow.
Warning/Fault Messages
WARNING/ALARM 3 - No motor
No motor has been connected to the output of the inverter.
WARNING/ALARM 9 - Inverter overloaded
The inverter is about to cut out because of an overload (too
high current for too long). The counter for electronic, thermal
inverter protection gives a warning at 98% and trips at 100%,
while giving an alarm. You cannot reset the inverter until the
counter is below 90%.The fault is that the inverter is
overloaded by more than nominal current for too long.
WARNING/ALARM 10 - Motor ETR over temperature
According to the electronic thermal protection (ETR), the
motor is too hot. You can choose if you want the inverter to
give a warning or an alarm when the counter reaches 100% in
programming par. 1-90 Motor Thermal Protection. The fault is
that the motor is overloaded by more than nominal current for
too long. Check that the motor in programming par. 1-24
Motor Current is set correctly.
WARNING/ALARM 11 - Motor thermistor over temp
The thermistor or the thermistor connection is disconnected.
You can choose if you want the inverter to give a warning or
an alarm in par. 1-90 Motor Thermal Protection. Check that the
thermistor is connected correctly between terminal 53 or 54
(analog voltage input) and terminal 50 (+ 10 Volts supply), or
between terminal 18 or 19 (digital input PNP only) and
terminal 50. If a KTY sensor is used, check for correct
connection between terminal 54 and 55.
WARNING/ALARM 13 - Over Current
The inverter peak current limit (approx. 200% of the rated
current) is exceeded. The warning will last approx. 8-12 sec,
then the inverter trips and issues an alarm. Turn off the inverter
and check if the motor shaft can be turned and if the motor size
matches the inverter.
ALARM 14 - Earth fault
There is a discharge from the output phases to earth, either in
the cable between the inverter and the motor or in the motor
itself. Turn off the inverter and remove the earth fault.
ALARM 16 - Short-circuit
There is short-circuiting in the motor or on the motor
terminals. Turn off the inverter and remove the short-circuit.
WARNING 23 - Internal fans
External fans have failed due to defective hardware or fans not
mounted.
WARNING/ALARM 4 - Mains phase loss
A phase is missing on the supply side, or the mains voltage

The VFD constantly monitors the chilled water system's state.
When the building cooling load drops, air side controls will
start to close in order to control the space temperature. At that
instant in time, the pump power draw will start to drop. The
drive will notice this and slow down the pump (Hz output will
decrease), which then triggers a decrease in flow and head
since the pump impeller rpm is dropping.
The reverse is true, when the load increases (valves open), the
power draw will increase and the drive will speed up (Hz goes
up) and the flow and head increases.
Both flow and head will fluctuate and since they are being read
instantaneously, as opposed to an averaged value, even the
slightest change is registered on the screen. This gives the
readings a jumpy appearance.
A building's cooling load tends to change slowly and it may be
difficult to discern load changes by merely observing the VFD
display. However, the pump rpm, Hz and kW can be noted
over time and used for reference. A given building load will
have a discrete reading.
Observing the pump kW power input at various cooling loads
will indicate the large amount of electrical energy saved by the
VFD.

Start-up and Shutdown
In addition to making any settings required, it is often
desirable to run the pumps without the chiller running to check
the chilled water circuit. De-energize the compressors by
turning off the three switches located in the unit left-hand
control panel (SW1, PS1 and PS2). Energize the unit by
closing the main disconnect located in the right-hand panel
door. Non-VFD pumps can then be operated using the switch
located on the door of the pump control panel. Use the dispay
keypad on VFD unit for operation. Press the Hand on key and
use the ? or ? key to regulate the pump speed and flow. The
VFD should be changed to the Auto mode for normal
operation.
Setting the Operating Mode
For convenience, the operating parameters for each of the three
operating modes have pre-programmed setups.

9 Press AUTO for normal operation.
10 Press STATUS to return to the normal operating screen.
Pre-start Up
Follow the chiller start-up procedure outlined in the current
chiller installation and operating manual, available on
www.DaikinApplied.com. In addition, check that the pump
package is operating normally in accordance with its sequence
of operation.
Check rotation of the pump by bumping it. It should be
clockwise when viewed from the top of the motor looking
down at the fan rotation.
Do not run the pump without fluid in the system. Fluid is
required to cool and lubricate the pump.
Before starting pump(s) and with water in the pump, purge the
seal flush line by cracking the vent valve until water appears.
The valve will protrude from the pump insulation. The seal is
the highest point in the pump and requires water for sealing
and lubrication.
VFD equipped pumps are shipped with the pump VFD
controller in the AUTO mode. Confirm this by checking the
VFD controller and pressing the Auto key if necessary. The
AUTO ON button is located at the bottom on the controller.
See Figure 20, page 48.
Check that the "Y" strainer
valve is open (horizontal
position) and the triple-
Vent

duty valve is open.
Hold-down Bolts
Start Up
Occasionally the impeller may be temporarily bound up and
will not turn at start up. If this is the case, loosen the insulation
and loosen the hold-down bolts holding the motor assembly to
the pump casing (do not remove them) and bump the pump.
The pump package is shipped with three strainers:
• A "Y" type strainer at the unit inlet connection
• A perforated strainer located in the inlet guide assembly at
the inlet of the pump.
• A fine mesh temporary start-up strainer located in the inlet
guide.
The "Y" strainer has a finer mesh than the inlet guide strainer
and should catch most debris before it reaches the inlet guide
strainer, which also functions as suction flow direction device.
No special attention need be paid to the suction guide strainer
at initial start-up. It will strain the pumped fluid and stabilize
the flow into the pump suction automatically.
Removing Temporary Strainer
The temporary strainer must be removed following system
clean up as follows:
After all debris has been removed from the system, or a
maximum of 24 running hours, stop the pump and close the
pump isolation valves. Drain the suction guide by removing
the drain plug or opening the blowdown valve, if installed.
Remove the insulation disc held on with Velcro (the disc has a
"CAUTION Remove Startup Strainer After 24 Hours” sticker).
Remove the suction guide cover and remove the strainer
assembly from the valve body.
52IM 1110-1
Page 53
Start-up and Shutdown
The temporary fine-mesh start-up strainer is tack-welded to the
permanent stainless steel strainer. This temporary strainer
should now be removed from the permanent strainer. The finemesh strainer is designed to remove small particulate from
new piping systems and could easily clog with debris if left in
place. This will be detrimental to the operation of the pump.
Replace the permanent strainer into the fitting body, once the
temporary strainer is removed.
Inspect the cover O-ring and replace if necessary. Replace the
cover into the body. Ensuring that the strainer is properly
seated, tighten the cover bolts diagonally, evenly and firmly.
The seal may drip at initial start up as it breaks in. If the drip
continues for more than a few hours, service may be required.
Figure 27: Temporary Strainer to be Removed
Seasonal Shutdown
Follow the instructions in the chiller unit for seasonal
shutdown procedures. In addition for the pump package:
No components or piping on the pump package are heat traced.
If heat tracing is field installed, carefully remove the factory
insulation, install the heat tracing and carefully replace the
insulation, being careful to seal it against moisture penetration.
If draining the chilled water system, see diagrams beginning
on page 5 for the location of drain points in the piping and
pumps, both of which must be thoroughly drained.

Setup for BAS Integration
Setup for BAS Integration
Introduction
The VFD pump supports an optional interface that allows
control by a Building Automation System (BAS). The pump
can be integrated to a BAS via BACnet® MS/TP,
LONWORKS® or Modbus network protocols. The
appropriate MicroTech® III communication module must be
selected as a factory-installed option on the AGZ-D chiller.
The chiller communication module determines the
corresponding protocol of the VFD pump package frequency
converter. The VFD pump controller ships from the factory
with the protocol option that matches the communication
module selected with the chiller. Note that while BACnet IP is
offered as a factory-installed option on the AGZ-D chiller,
BACnet IP is not offered on the VFD frequency converter. If a
chiller unit is ordered with BACnet IP, the VFD will be
provided with BACnet MS/TP. The VFD controller comes
with an attached "option card" for BACnet and LonWorks.
The VFD controller is a native Modbus device and does not
require an "option card" for the Modbus protocol.
Network parameters are set using the VFD controller's
graphical interface. The following sections describe the
parameters that are required to enable communications from
the VFD pump directly to the BAS via BACnet MS/TP,
LONWORKS, or Modbus. Selecting a specific
communication protocol changes various default parameter
settings to match that protocol's specifications along with
making additional protocol-specific parameters available from
the BAS.
Configuring the VFD Controller for BACnet
MS/TP Communication
This following section assumes you are using a BACnet
Option Card in conjunction with the AGZ-D pump package
frequency converter (seeFigure 28). It is also assumed that the
VFD pump controller is connected to a "master" BAS or PC
equipped with a serial communication card supporting all the
BACnet communication services required by your application,
and that all requirements stipulated in the BACnet standard, as
well as those pertaining to the VFD pump controller are
strictly observed as well as all limitations therein fully
respected.
The BACnet Option Card is designed to communicate with
any master complying with the BACnet standard. Familiarity
with the PC used as a master in the system is assumed.
Light Emitting Diodes (LEDs)
Two bi-colored LEDs indicate communication activity and
status of BACnet communications. These indicators can be
seen when the BACnet Option Card is connected to the VFD
pump controller. Descriptions of the two LEDs are
summarized in Table 29 and Table 30.
Figure 28: BACnet Option Card
VFD Network Integration
Use the VFD controller's graphical interface to set unit
parameters and factory defaults for unit setpoints. Refer to the
previous section in this IOMM for details on how to use the
graphical interface.
Network configuration involves: 1) selecting the Control
Protocol for BACnet, LONWORKS, or Modbus, and 2) then
setting the specific network parameters as required by each
protocol. The addressing parameters specific to BACnet,
LONWORKS, and Modbus are described separately in the
sections that follow.
The comprehensive set of network parameters available from
the VFD pump to the BAS (i.e. point lists) are provided in
separate AGZ-D VFD Pump Controller Operations Manuals
for each protocol. These point lists can be found on
www.DaikinApplied.com in both the MicroTech III Controls
and AGZ-D chiller literature pages. For questions regarding
the VFD pump operation and set up, please contact the chiller
Technical Response Group (TRC) at 877-349-7782.
Note: AGZ-D chiller VFD controllers support only BACnet MS/
TP, LONWORKS, and Modbus communications. Daikin
Applied does not support other protocol options that may
be offered by the VFD manufacturer.
Steps for BACnet MS/TP Configuration
1 Set the basic BACnet MS/TP network parameters using
the VFD graphical interface. These BACnet parameters
are described in Table 28below. It is recommended that
additional parameters available in menu 8-* should
remain at factory defaults. See VFD installation manual
for further details (available on
www.DaikinApplied.com).

Configuring the VFD Controller for LONWORKS Communication
Introduction
This following section assumes you are using a LONWORKS
Option Card in conjunction with the AGZ-D pump package
frequency converter (seeFigure 30, LONWORKS
Connection). The LONWORKS Option Card is LonMark 3.4
certified. It is designed to communicate with any system
complying with the FTT-10A and 78kbps LONWORKS
standard. Familiarity with this technology is assumed.
The LONWORKS communications structure is similar to that
of a local area network (LAN) in that messages are continually
exchanged between a number of processors. A LONWORKS
system is a local operating network (LON). LON technology
offers a means for integrating various distributed systems that
perform sensing, monitoring, control, and other automated
functions. A LON allows these intelligent devices to
communicate with one another through a variety of
communications media using a standard protocol. LON
technology supports distributed, peer-to-peer communications.
That is, individual network devices can communicate directly
with one another without the need for a central control system.
Data are transported by means of standard network variable
types (SNVTs) which provide the interface for communication
between devices from different manufacturers. LONWORKSdefined functional profiles determine the functionality and
network variables for a particular family of devices (e.g.
frequency converters, pumps etc.) are also available, and
supported by the LONWORKS option.
The VFD controller typically does not involve network
addressing to enable BAS communication. However, there are
several basic steps required for LONWORKS integration,
which are described in the following section. Additionally, the
available network parameters are available via the graphical
interface as shown inTab le 31.
Figure 30: LONWORKS Connection
Service Pin Switch
The service pin generates a service-pin message that contains
the Neuron® ID and the program code identification of the
node. A service-pin message is a network message that is
generated by a node and broadcast on the network. It can be
used to commission the VFD controller to the LONWORKS
network. The service pin switch is located on the lower righthand corner of the LonWorks Option Card. See Figure 30 for
location of the service pin.
Light Emitting Diodes (LEDs)
Two LEDs indicate communication activity and status of the
LonWorks Option Card. These indicators can be seen when the

Configuring the VFD Controller for Modbus
Communication
Introduction
The VFD controller (frequency controller) is a native Modbus
device. In other words, it does not require any additional
communication card or other hardware for integration into a
building automation system (BAS) via the Modbus network.
The configuration process is described in the following
section. It is assumed that the user is familiar with Modbus
technology and terminology.
Standard Modbus network rules apply. The network is a daisychain of unit controllers including the master (in this case, the
BAS) and all slaves (VFD controller). The Modbus standard
recommends that the network be terminated on each end with
the characteristic impedance of the network (about 120 ohms).
Follow the guidelines stated in the Modbus specifications.
Steps for Modbus Configuration
Configurable Parameters
Table 33 defines the network parameters of the Modbus
Communication Module that are available via the graphical
interface. The Modbus network address and data transmission
rate (Baud Rate) are available via the local control panel. At a
minimum, you must set the network address and verify the
correct baud rate before establishing network communication
between the VFD controller and the BAS. Change remaining
parameters as required for your network.
1 Set the Modbus network parameters as described in
Table 21. It is recommended that remaining items in
menus 8-* remain at factory defaults. See VFD
installation manual, available on
www.DaikinApplied.com for further details.
2 Cycle power to the VFD controller for changes to take
effect.
3 Verify connection from BAS to VFD - terminals 68 (+)
and 69 (-) on the main control board of the frequency
converter. Refer to Figure 35.
4 The VFD controller is now ready for network
configuration from the BAS. Refer to the Modbus

DANGER
Electric equipment can cause electric shock with a risk of severe personal injury or death. Turn off, lock out and tag all power
before continuing with following service. Panels can have more than one power source.
CAUTION
Service must be performed by trained, experienced refrigeration personnel familiar with equipment operation, maintenance,
correct servicing procedures, and the safety hazards inherent in this work. Causes for repeated tripping of equipment protection
controls must be investigated and corrected.
Lubrication
No routine lubrication is required on pump packages. The
pump motors are TEFC and permanently lubricated. The
pump seal is cooled and lubricated by the pumped fluid.
Mechanical Seal
Mechanical seals require no special attention. The mechanical
seal is fitted with a flush line. The seal is flushed from
discharge of the pump casing and is flushed/vented to the
suction on close coupled pumps.
POE type oil is used for compressor lubrication. ARNING
Do not run the pump unless properly filled with water as the
mechanical seals need a film of liquid between the faces for
WARNING
POE oil must be handled carefully using proper protective
equipment (gloves, eye protection, etc.) The oil must not come
in contact with certain polymers (e.g. PVC), as it may absorb
moisture from this material. Also, do not use oil or refrigerant
additives in the system.
For unit lubrication requirements, consult the current version
of the chiller operation manual at www.DaikinApplied.com.
