NOTES:

- Above capacity data based on 0oF subcooling and at sea level.

- For High Altitude applications apply the following correction factors: 0.94 for 2000 feet, 0.88 for 4000 feet and 0.81 for 6000 feet.

- Capacities at other TD within a range of 10 to 30 °F (-12.2 to -1°C) are directly proportional to TD, or use formula: Capacity = Rated capacity ÷ 10 x TD.

- For 50 HZ capacity multiply by 0.92. (No derate for EC motors)

- Capacities for R407A and R407C are based on mean temperature. Mean temperature is the average temperature between the saturated condensing
temperatures at the inlet and outlet of the condenser. For dew point ratings, consult factory.

ABOUT EC MOTORS

EC MOTORS

60Hz

Air cooled condensers utilizing electrically commutat-

ed motor (EC motor) technology offer many benets;
Improved Efciency, Reduced Sound Levels, Speed

Control, Simplicity and Reliability

Efciency

The speed control function of an EC motor allows the
condenser to run at optimized energy levels at differ­ent operating conditions. Up to 75% in energy sav­ings can be realized when comparing the EC motor
speed control method to a conventional fan cycling
method. See table below for power consumption and
energy savings comparisons.

Sound

As EC motor speeds vary for different operating
conditions they also offer reduced sound levels when
compared to conventional motor running full speed.
Sound levels are reduced on cooler days and in
evenings.

ELECTRICAL DATA

TCS

(OPTIONAL EC MOTORS)

Head Pressure Control

EC motors make it easier to maintaining stable head
pressures when motor speeds are varied accord­ing to operating conditions. System optimization is
further enhanced compared to the system shock from
conventional cycling banks of fans off and on.

Simplicity and Reliability

The installation and control of EC motors is very
simple compared to other methods of speed control
used on conventional AC motors. Lower running op­erating temperatures and smooth transitional speed
changes make EC motors durable and reliable.

Motors With Built-in Variable Speed –

Units with an EC (electronically commutated) motor provide
variable speed control. ECM motors use DC motors with
integral AC to DC conversion allowing direct connection to

AC mains with the energy saving and control benets of a

DC motor. Ideally the motors on the condenser should all
be EC and simultaneously slow down /speed up together.
This provides for maximum energy savings. However some
applications may exist where just the last fan or pair of fans
(ones closest to header) is solely EC motors. (The remain­ing conventional type motors are then cycled off by fan
cycling pressure controls).

Important Warnings:
(Please read before handling motors)

1. When connecting the unit to the power supply, danger
ous voltages occur. Due to motor capacitor discharge
time, do not open the motor within 5 minutes after
disconnection of all phases.

2. With a Control voltage fed in or a set speed value being
saved, the motor will restart automatically after a power
failure.

3. Dangerous external voltages can be present at the
motor terminals even when the unit is turned off.

4. The Electronics housing can get hot.

Speed Adjustment Characteristics

The EC motor varies its speed linearly based on a
1-10V input signal. At 10 VDC, the motor runs at full
speed. At 0 to approx. 1 VDC, the motor turns off. A
chart of the speed control curve is shown below. The
motor can be controlled at any speed below its nominal
RPM.

RPM

1

Control voltage [V dc]

Control Signal

The input control signal can be supplied by an external
control signal or from a factory installed proportional
pressure control. Units with factory installed propor­tional pressure controls require no installation wiring
and are adjusted with initial factory settings. These
may require further adjustments to suit local eld con­ditions.

10

5. The cycling on and off of EC motors should be
controlled by the DC control voltage (i.e. 0V DC will turn
motor off). Excessive cycling of the motor by line
voltage contactors may cause stress on the motors and
reduce the motor life.

External Control Signal (Supplied by others)

Contact control manufacturer for setup of external con­troller to provide a 0-10 VDC control signal. Wire the
control signal to terminal board in unit control box. See
EC Diagram on P.12 for typical external signal control
wiring.

GENERAL

When air-cooled condensers are installed outdoors, they
will be subjected to varying ambient temperatures. This
variance could be as much as 120°F (48.9 °C) of swing
throughout the summer and winter seasons and will have
a major impact on the performance of the condenser. As
the ambient temperature drops, the condenser capac­ity will increase due to the wider temperature difference
between ambient and condensing temperature. As this
happens, the condensing temperature will also drop as the

system nds a new balance point. Although overall system

capacity will increase, other problems can occur. The ca­pacity of an expansion valve is affected by both the liquid
temperature entering the valve and the pressure drop
across it. As the condensing temperature decreases, the
pressure drop across the metering device also decreases.
This lower pressure drop will then decrease the capacity of
the valve. Although lower liquid temperatures increase the
capacity of the metering device, the increase is not large
enough to offset the loss due to the lower pressure drop.
To provide adequate pressure drop, some form of head
pressure control is required. Refer to the following design
methods (covered in order of simplicity and features).

(i) Fan Cycling (Multiple Fans)

Cycling of the condenser fans helps regulate the condens­ing temperature. Using this approach, as the ambient
drops the fans are taken off-line either one at a time, or in
pairs. With multiple fan condensers, it is not recommended
to cycle more than two fans per step. The reason is that
the pressure in the condenser will increase drastically
as several fans are taken off-line at the same time. This
will result in erratic operation of the refrigeration system
and applies additional stress to the condenser tubes. It
is preferable to regulate the condensing temperature as
smoothly as possible. Fans should be cycled independent­ly on single row condenser fan models. On double wide
condensers, when used with a single refrigeration circuit,
the fans should be cycled in pairs.

(ii) Variable Motor Speed Control

If additional head pressure control is required beyond the
last step of fan cycling variable fan motor speed may be
used. Variable motor speed is optional on all condenser
models. A varying motor speed may be accomplished using
a modulating temperature or modulating pressure control. A
variable speed controller can be an electronic or solid state
device which varies the voltage going to the motor depend­ing on the temperature or pressure of the medium being
sensed.

(iii) Refrigerant Regulating Controls

Pressure regulating controls are available from a number
of valve manufacturers. The purpose of such a control is
to regulate the refrigerant ow in such a way as to main­tain a pre-selected condensing pressure. In lower ambient
temperatures, these valves throttle to maintain the desired

pressure and in doing so, ood the condenser with liquid

refrigerant.The larger the condenser surface is, the higher

its capacity will be. When a condenser is ooded, its useful

condensing surface is reduced. This is because the refrig­erant occupies the space which would otherwise be used
for condensing.

Some control/check valve combinations will regulate

refrigerant ow depending on the pressure at the inlet of

the condenser.These are often referred to as inlet regula­tors. As the valve closes, hot gas bypasses the condenser

through a differential check valve to increase the pressure
at the receiver.

Ambient temperature or pressure sensing controls can be
set to bring on (or off) certain fans when the outdoor tem­perature or condensing pressures reach a predetermined
condition. Temperature or pressure set points and differen­tials should be correctly set to prevent short cycling of the
fans. Constant short cycling will produce volatile condens­ing pressures, erratic refrigeration performance, decreased
fan motor life, and added stress to the condenser tubes.

For recommended fan cycling switch settings, refer to
Tables 4 and 5. Differential settings on fan cycling tem­perature controls should be no lower than 3.5°F (2°C). On
fan cycling pressure controls with R404A, a differential of
approximately 35 psig is recommended. On supermarket
applications remote condenser fans may be cycled individ­ually (not in pairs) and therefore lower differential settings

may apply and will depend on the specic application.

Fans closest to the inlet header must run whenever the
compressor is running and should NEVER be cycled since
sudden stress changes placed on these inlet tubes and
headers will dramatically shorten the life of the condenser.

Table 1 shows the fan cycling congurations and options

available for all remote condenser models.

SINGLE VALVE CONDENSER PRESSURE CONTROL

(Regulates inlet pressure or outlet pressure depending on valve design)

This will ood the condenser until the condensing

pressure increases to a point which will again open
the valve. Other valves regulate the refrigerant at the
outlet of the condenser to provide a similar effect.
These are commonly referred to as outlet regulators.
There are also combination inlet/outlet
regulators with a differential check valve or other
type of condenser bypass arrangement incorporated
within the valve.

Controls which regulate the ow of refrigerant based

on condenser inlet pressure are typically used in
conjuction with a check valve having a minimum
opening differential across the condenser. Outlet

regulators typically require a check valve with a xed

pressure differential setting of between 20 and 35
psi. The differential is needed to compensate for
pressure drop through the condenser

during ooding and associated discharge piping.

Systems equipped with a condenser ooding

arrangement should always use a receiver having

sufcient liquid holding capacity. Additional liquid
required for ooding is only required during the winter

low ambients and must be stored somewhere in the
system at the higher ambients. Failure to use an
adequately sized receiver will result in liquid back-up
in the condenser during the warmer summer months.
This will cause the system to develop very high
pressures in the high side resulting in a high pressure
safety control trip.

ORI / ORD CONDENSER PRESSURE CONTROL

Determining Additional Flooded
Refrigerant Charge

Additional charge will vary with the condenser
design TD and the coldest expected ambient
temperature. Condensers designed for low TD
applications (low temperature evaporators) and
operating in colder ambients will require more
additional charge than those designed for higher
TD applications (high temperature evaporators)
and warmer ambients.
Refer to tables on pages 21-22 to determine
the required added refrigerant charge at the
selected TD and ambient temperatures.
These charges are based on condensers using Fan
Cycling options with their last fan (Single Row Fan
Models) running or last pair of fans running (Double
Row Fan models).

WARNING: Do not over charge when charging by a
sightglass. Liquid lines feeding the TXV at the
evaporator must have a solid column of liquid (no
bubbles) however bubbles at the sightglass (located
adjacient to the receiver) may be normal due to the
result of a higher pressure drop at that point. Bubbles
could also appear in the glass whenever the

regulating valves start to ood the condenser.

Always record the number of drums or the weight of
refrigerant that has been added or removed in the
system. Overcharged systems may result in
compressor failure as well as other serious mechanical
damage to the system components.

losses or damage. Electrical characteristics should also
be checked at this time to ensure that they are correct.

LOCATION

Before handling and placing the unit into position a review
of the most suitable location must be made. This
condenser is designed for outdoor installation.
A number of factors must be taken into consideration

Horizontal Air Discharge

(Standard Shipping Conguration)

when selecting a location. Most important is the provision
for a supply of ambient air to the condenser, and removal
of heated air from the condenser area.
Higher condensing temperatures, decreased
performance, and the possibility of equipment failure
may result from inadequate air supply.
Other considerations include:

1. Customer requests

2. Loading capacity of the roof or oor.

3. Distance to suitable electrical supply.

4. Accessibility for maintenance.

5. Local building codes.

6. Adjacent buildings relative to noise levels.

WALLS OR OBSTRUCTIONS

All sides of the unit must be a minimum of 4 feet

(1.25 m) away from any wall or obstruction. Overhead
obstructions are not permitted. If enclosed by three
walls, the condenser must be installed as indicated for
units in a pit.

LOUVERS/FENCES

Louvers/fences must have a minimum of 80% free area
and 4 feet (1.25 m) minimum clearance between the
unit and louvers/fence. Height of louver/fence
must not exceed top of unit.

MULTIPLE UNITS

A minimum of 8 feet (2.5 m) is required between
multiple units placed side by side. If placed end to end,
the minimum distance between units is 4 feet (1.25 m).

UNITS IN PITS

The top of the condenser must be level with, or above
the top of the pit. In addition, a minimum of 8 feet
(2.5 m) is required between the unit and the pit walls.

MULTIPLE UNITS

A minimum of 8 feet (2.5 m) is required between
multiple units placed side by side. If placed end to end,
the minimum distance between units is 4 feet (1.25 m).

PLACEMENT

Once a suitable location is selected ensure all the remote
mounting parts (legs and hardware) are available. Refer to
Fig.1b (P. 26) and the dimensional data on pages 14-15 for
the leg mounting locations.

Optional horizontal

For horizontal air ow
conguration, Outlet

header connection
MUST be at the bottom.

Air cooled condensers are large, heavy mechanical

equipment and must be handled as such. A fully qualied

and properly equipped crew with necessary rigging should
be engaged to set the condenser into position. Lifting
brackets or holes have been provided at the
corners for attaching lifting slings. Spreader bars must be
used when lifting so that the lifting force must be
applied vertically. Under no circumstances should the

coil headers or return bends be used in lifting or
moving the condenser.

Ensure the unit is placed in a level position (to ensure
proper drainage of liquid refrigerant and oil). The legs
should be securely anchored to the building structure,
sleeper or concrete pad. The weight of the condenser is
not enough to hold in place during a strong wind, the legs

must be anchored.

FOR MOVING INTO VERTICAL

AIR FLOW POSITION

Legs are fastened to

end panel side anges

usiing 5/16-18 bolts and
lock-nuts provided with
optional leg kit.

DISCHARGE LINES

Discharge lines should be designed to minimize

refrigerant pressure drop, since high pressure losses
increase the required compressor horsepower per ton of
refrigeration.

Discharge lines must be pitched away from the
compressor to ensure proper drainage of oil being
carried in the line.
A discharge check-valve at the bottom of a vertical riser
will prevent oil (and liquid refrigerant) from draining back
to the compressor during the off-cycle. When the vertical
lift exceeds 30 feet (10 m), insert close-coupled traps in
the riser at 30 feet (10 m) intervals.

An alternate method of handling the oil problem would
be the addition of an oil separator see Figure 3 (b).

REFRIGERANT PIPING

All refrigeration piping must be installed by a qualied

refrigeration mechanic. The importance of correct
refrigerant pipe sizing and layout cannot be over­emphasized. Failure to observe proper refrigerant piping
practices can result in equipment failure which may not be
covered under warranty.
All air cooled condensers are supplied complete with
headers and refrigerant connections sized for connecting
to standard refrigeration tubing.These connections may
not be the same as the actual line sizes required for the

eld installation. Refer to a recognized source (ASHRAE

charts, manufacturer’s engineering manuals etc.) for line
sizing.

A reverse trap should be installed at the top of all vertical
risers. The top of the reverse trap should be the highest
point in the discharge line and should have an access
valve installed to allow the reclaimation of non-condensible
gas from the system.

Pulsation of the hot gas in the discharge line is an inherent
characteristic of systems utilizing reciprocating
compressors. The discharge line must be rigidly
supported along its entire length to prevent transmission
of vibration and movement of the line.

CONDENSATE LINES

The condensate line must be designed to allow free
drainage of refrigerant from the condenser coil to the
receiver. Refer to Fig. 4 for typical condensate line piping
when utilizing head pressure regulating valves.

ELECTRICAL WIRING

All wiring and connections to the air cooled condenser
must be made in accordance with the National Electri­cal Code and all local codes and regulations. Any wiring
diagrams shown are basic and do not necessarily

include electrical components which must be eld

supplied. (see pages 5-9 and 11-12 for typical wiring
diagrams).

Refer to the Electrical Specications table on pages

4 and 10 for voltage availability and entering service
requirements.

SYSTEM START-UP CHECKS

1. Check the electrical characteristics of all components
to be sure they agree with the power supply.

2. Check tightness of all fans and motor mounts.

3. Check tightness of all electrical connections.

4. Upon start-up, check fans for correct rotation. Air is
drawn through the condenser coil. To change rotation
on 3 phase units reverse any two (2) fan motor leads.

5. All system piping must be thoroughly leak checked
before a refrigerant charge is introduced.

5. Short cycling fan motors can result in premature failure
of the fan blades and/or motors. Failing to correct this
problem may, over time, cause the rivets on fan blades
to become loose. If this happens, the fan blade may
crack or tear, causing extreme vibration, potentially
triggering the motor and mounts to fail.

6. Check the tightness of all fan blades and motors.
Remove any dirt or debris that could affect the balance
of the fan blade.

7. Fan motors are permanently lubricated and require only
visual inspection
