SHIPPING DAMAGE
DUCT WORK
Upon receipt of equipment, the carton should be
checked for external signs of shipping damage. If
damage is found, the receiving party must contact the
last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.
GENERAL
The equipment covered in this manual is to be
installed by trained, experienced service and
installation technicians.
The refrigerant system is completely assembled and
charged. All internal wiring is complete.
The unit is designed for use with or without duct
work. Flanges are provided for attaching the supply
and return ducts.
These instructions explain the recommended method
to install the air cooled self-contained unit and the
electrical wiring connections to the unit.
These instructions and any instructions packaged with
any separate equipment required to make up the entire
air conditioning system should be carefully read
before beginning the installation. Note particularly
“Starting Procedure” and any tags and/or labels
attached to the equipment.
All duct work, supply and return, must be properly
sized for the design air flow requirement of the
equipment. Air Conditioning Contractors of America
(ACCA) is an excellent guide to proper sizing. All
duct work or portions thereof not in the conditioned
space should be properly insulated in order to both
conserve energy and prevent condensation or moisture
damage.
Refer to Table 9 for maximum static pressure available
for duct design.
Design the duct work according to methods given by
the Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should be
insulated with a minimum of 1 inch of insulation. Use
insulation with a vapor barrier on the outside of the
insulation. Flexible joints should be used to connect
the duct work to the equipment in order to keep the
noise transmission to a minimum.
A 1/4 inch clearance to combustible material for the
first three feet of duct attached to the outlet air frame is
required. See Wall Mounting Instructions and Figures
4 and 5 for further details.
Ducts through the walls must be insulated and all
joints taped or sealed to prevent air or moisture
entering the wall cavity.
While these instructions are intended as a general
recommended guide, they do not supersede any
national and/or local codes in any way. Authorities
having jurisdiction should be consulted before the
installation is made. See Page 1 for information on
codes and standards.
Size of unit for a proposed installation should be based
on heat loss calculation made according to methods of
Air Conditioning Contractors of America (ACCA).
The air duct should be installed in accordance with the
Standards of the National Fire Protection Association
for the Installation of Air Conditioning and
Ventilating Systems of Other Than Residence Type,
NFPA No. 90A, and Residence Type Warm Air
Heating and Air Conditioning Systems, NFPA No.
90B. Where local regulations are at a variance with
instructions, installer should adhere to local codes.
CAUTION
Some installations may not require any return
air duct. A metallic return air grille is required
with installations not requiring a return air
duct. The spacing between louvers on the
grille shall not be larger than 5/8 inches.
Any grille that meets the 5/8 inch louver criteria, may
be used. It is recommended that Bard Return Air Grille
Kit RG-2 thru RG-5 or RFG-2 thru RFG-5 be installed
when no return duct is used. Contact distributor or
factory for ordering information. If using a return air
filter grille, filters must be of sufficient size to allow a
maximum velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
Manual 2100-425

FILTERS
A 1 inch throwaway filter is supplied with each unit.
The filter slides into position making it easy to service.
This filter can be serviced from the outside by
removing the service door. A 1 inch washable filter
and 2 inch pleated filter are also available as optional
accessories. The internal filter brackets are adjustable
to accommodate the 2 inch filter by bending down the
tabs to allow spacing for the 2 inch filters.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service panel.
If the unit is equipped with the fresh air damper
assembly, the assembly is shipped already attached to
the unit. The damper blade is locked in the closed
position to allow the damper to operate, the maximum
and minium blade position stops must be installed.
See Figure 2.
BLOWER DAMPER ASSEMBLY
All capacity, efficiency and cost of operation
information as required for Department of Energy
“Energyguide” Fact Sheets is based upon the fresh air
blank-off plate in place and is recommended for
maximum energy efficiency.
The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.
CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or
vented type system to assure proper drainage.

INST ALLA TION INSTRUCTIONS
WALL MOUNTING INFORMATION
1. Two holes, for the supply and return air openings,
must be cut through the wall as shown in Figure 3.
2. On wood-frame walls, the wall construction must
be strong and rigid enough to carry the weight of
the unit without transmitting any unit vibration.
See Figures 4 and 5.
WARNING
Fire hazard can result if 1/4 inch clearance to
combustible materials for supply air duct is
not maintained. See Figure 3.
3. Concrete block walls must be thoroughly inspected
to insure that they are capable of carrying the
weight of the installing unit. See Figure 4.
MOUNTING THE UNIT
1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket is provided
for ease of installation.
2. The unit itself is suitable for “0” inch clearance,
but the supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1/4 inch
clearance to combustible material. If a combustible
wall, use a minimum of 30-1/2" x 10-1/2"
dimensions for sizing. However, it is generally
recommended that a 1 inch clearance is used for
ease of installation and maintaining the required
clearance to combustible material. The supply air
opening would then be 32" x 12". See
Figures 3, 4 and 7 for details.
WARNING
Failure to provide the 1/4 inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
fire.
3. Locate and mark lag bolt locations and bottom
mounting bracket location. See Figure 4.
4. Mount bottom mounting bracket.
5. Hook top rain flashing under back bend of top.
Top rain flashing is shipped secured to the right
side of the back.
6. Position unit in opening and secure with 5/16 lag
bolts; use 7/8 inch diameter flat washers on the lag
bolts.
7. Secure rain flashing to wall and caulk across entire
length of top. See Figure 3.
8. For additional mounting rigidity, the return air and
supply air frames or collars can be drilled and
screwed or welded to the structural wall itself
(depending upon wall construction). Be sure to
observe required clearance if combustible wall.
9. On side by side installations, maintain a minimum
of 20 inches clearance on right side to allow access
to heat strips and control panel and to allow proper
airflow to the outdoor coil. Additional clearance
may be required to meet local or national codes.
TYPICAL INSTALLATIONS
See Figure 6 for common ways to install the wallmount unit.
WIRING — MAIN POWER
Refer to the unit rating plate for wire sizing
information and maximum fuse or “HACR" type
circuit breaker size. Each outdoor unit is marked with
a “Minimum Circuit Ampacity”. This means that the
field wiring used must be sized to carry that amount of
current. Depending on the installed KW of electric
heat, there may be two field power circuits required. If
this is the case, the unit serial plate will so indicate. All
models are suitable only for connection with copper
wire. Each unit and/or wiring diagram will be marked
“Use Copper Conductors Only”. These instructions
must be adhered to. Refer to the National Electrical
Code (NEC) for complete current carrying capacity
data on the various insulation grades of wiring
material. All wiring must conform to NEC and all
local codes.
The electrical data lists fuse and wire sizes (75ºC
copper) for all models, including the most commonly
used heater sizes. Also shown are the number of field
power circuits required for the various models with
heaters.
Manual 2100-425
Page 7
The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or “HACR" type circuit breaker that is to
be used with the equipment. The correct size must be
used for proper circuit protection and also to assure
that there will be no nuisance tripping due to the
momentary high starting current of the compressor
motor.
The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect. To
MOUNTING INSTRUCTIONS
convert for the locking capability, bend the tab located
in the bottom left hand corner of the disconnect
opening under the disconnect access panel straight
out. This tab will now line up with the slot in the door.
When shut, a padlock may be placed through the hole
in the tab preventing entry.
See Start-up section for information on three phase
scroll compressor start-ups.

START UP
IMPORTANT INSTALLER NOTE
For improved start-up performance, wash the indoor
coil with a dishwasher detergent.
CRANKCASE HEATERS
WA611, WA70 and WA721 units are provided with
compressor crankcase heat.
The WA611, WA70 and WA721 models have a band
type heater located around the bottom of the
compressor. This heater is controlled by the crankcase
heater relay. The heater is only energized when the
compressor is not running.
Some form of crankcase heat is essential to prevent
liquid refrigerant from migrating to the compressor,
casing oil pump out on compressor start-up and
possible valve failure due to compressing a liquid.
The decal in Figure 9 is affixed to all WA611, WA70
and WA721 units detailing start-up procedure. This is
very important. Please read carefully.
FIGURE 9
START-UP LABEL
IMPORTANT
These procedures must be followed at
initial start-up and at any time power
has been removed for 12 hours or
longer.
To prevent compressor damage which may
result from the presence of liquid
refrigerant in the compressor crankcase.
1. Make certain the room thermostat is in
the "off" position (the compressor is
not to operate).
2. Apply power by closing the system
disconnect switch. This energizes the
compressor heater which evaporates
the liquid refrigerant in the crankcase.
3. Allow 4 hours or 60 minutes per pound
of refrigerant in the system as noted
on the unit rating plate, whichever is
greater.
4. After properly elapsed time, the
thermostat may be set to operate the
compressor.
5. Except as required for safety while
servicing – Do not open system
disconnect switch.
7961-061
HIGH PRESSURE SWITCH
The WA611, WA70 and WA721 models are supplied
with a remote reset high pressure switch. If tripped,
this pressure switch may be reset by turning the
thermostat off then back on again.
THREE PHASE SCROLL COMPRESSOR
START UP INFORMATION
Scroll compressors, like several other types of
compressors, will only compress in one rotational
direction. Direction of rotation is not an issue with
single phase compressors since they will always start
and run in the proper direction.
However, three phase compressors will rotate in either
direction depending upon phasing of the power. Since
there is a 50-50 chance of connecting power in such a
way as to cause rotation in the reverse direction,
verification of proper rotation must be made. All three
phase units incorporate a phase monitor to ensure
proper field wiring. See the Phase Monitor" section
later in this manual.
Verification of proper rotation must be made any time
a compressor is change or rewired. If improper
rotation is corrected at this time there will be no
negative impact on the durability of the compressor.
However, reverse operation for over one hour may
have a negative impact on the bearing due to oil pump
out.
NOTE: If compressor is allowed to run in reverse
rotation for several minutes, the
compressor's internal protector will trip.
All three phase ZR3 compressors are wired identically
internally. As a result, once the correct phasing is
determined for a specific system or installation,
connecting properly phased power leads to the same
Fusite terminal should maintain proper rotation
direction.
Verification of proper rotation direction is made by
observing that suction pressure drops and discharge
pressure rises when the compressor is energized.
Reverse rotation also results in an elevated sound level
over that with correct rotations, as well as,
substantially reduced current draw compared to
tabulated values.
The direction of rotation of the compressor may be
changed by reversing any two line connections to the
unit.
Manual 2100-425
Page 14
SERVICE HINTS
1. Caution homeowner to maintain clean air filters at
all times. Also, not to needlessly close off supply
and return air registers. This reduces air flow
through the system, which shortens equipment
service life as well as increasing operating costs.
2. Check all power fuses or circuit breakers to be sure
they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit full
and unrestricted airflow circulation is essential.
SEQUENCE OF OPERATION
During routine operation of the unit with no power
interruptions the compressor will operate on demand
with no delay.
High Pressure Switch and Lockout Sequence
If the high pressure switch opens, the compressor
contactor will de-energize immediately. The lockout
timer will go into a soft lockout and stay in soft
lockout until the high pressure switch closes and the
delay on break time has expired. If the high pressure
switch opens again in this same operating cycle the
unit will go into manual lockout condition and the
alarm relay circuit will energize. Recycling the wall
thermostat resets the manual lockout.
COOLING – Circuit R-Y makes at thermostat pulling
in compressor contactor, starting the compressor and
outdoor motor. The G (indoor motor) circuit is
automatically completed on any call for cooling
operation or can be energized by manual fan switch on
subbase for constant air circulation. On all 208/230
volt models, when G circuit is de-energized the indoor
blower motor will continue to run for one minute. On
a call for heating, circuit R-W1 make at the thermostat
pulling in heat contact for the strip heat and blower
operation. On a call for second stage heat, R-W2
makes bringing on second heat contactor, if so
equipped.
COMPRESSOR CONTROL MODULE
The compressor control module is standard on the
models covered by this manual. The compressor
control is an anti-short cycle/lockout timer with high
and low pressure switch monitoring and alarm relay
output.
Adjustable Delay On Make And Break Timer
On initial power up or any time power is interrupted to
the unit the delay on make period begins which will
be 2 minutes plus 10% of the delay on break setting.
When the delay on make is complete and the high
pressure switch (and low pressure switch if employed)
is closed, the compressor contactor is energized.
Upon shutdown the delay or break timer starts and
prevents restart until the delay on break and delay on
make periods have expired.
Low Pressure Switch, Bypass, and Lockout
Sequence
If the low pressure switch opens for more than 120
seconds, the compressor contactor will de-energize
and go into a soft lockout. Regardless the state of the
low pressure switch, the contactor will reenergize after
the delay on make time delay has expired. If the low
pressure switch remains open, or opens again for
longer than 120 seconds the unit will go into manual
lockout condition and the alarm relay circuit will
energize. Recycling the wall thermostat resets the
manual lockout.
Alarm Relay Output
Alarm terminal is output connection for applications
where alarm relay is employed. This terminal is
powered whenever compressor is locked out due to
HPC or LPC sequences as described.
NOTE: Both high and low pressure switch controls
are inherently automatic reset devices. The
high pressure switch and low pressure
switch cut out and cut in settings are fixed by
specific air conditioner or heat pump unit
model. The lockout features, both soft and
manual, are a function of the Compressor
Control Module.
Manual 2100-425
Page 15
ADJUSTMENTS
PHASE MONITOR
Adjustable Delay on Make and Delay on Break
Timer
The potentiometer is used to select Delay on Break
time from 30 seconds to 5 minutes. Delay on Make
(DOM) timing on power-up and after power
interruptions is equal to 2 minutes plus 10% of Delay
on Break (DOB) setting:
0.5 minute (30 seconds) DO B =123 second DOM
1.0 minute (60 seconds) DO B =126 second DOM
2.0 minute (120 seconds)DOB =132 second DOM
3.0 minute (180 seconds)DOB =138 second DOM
4.0 minute (240 seconds)DOB =144 second DOM
5.0 minute (300 seconds)DOB =150 second DOM
During routine operation of the unit with no power
interruptions the compressor will operate on demand
with no delay.
Typical Settings for Dual Unit Installation:
Unit 1: DOB set at 2 minutes, and DOM is 132 seconds
Unit 2: DOB set at 4 minutes, and DOM is 144 seconds
All units with three phase scroll compressors are
equipped with a 3 phase line monitor to prevent
compressor damage due to phase reversal.
The phase monitor in this unit is equipped with two
LEDs. If the Y signal is present at the phase monitor
and phases are correct the green LED will light.
If phases are reversed, the red fault LED will be lit and
compressor operation is inhibited.
If a fault condition occurs, reverse two of the supply
leads to the unit. Do not reverse any of the unit
factory wires as damage may occur.
PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all
units so that the system operating pressures can be
observed. Pressure tables can be found later in the
manual covering all models. It is imperative to match
the correct pressure table to the unit by model number.
