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.
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 3
and 3A for further details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wallcavity.
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 inch.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
Any grille that meets with 5/8 inch louver criteria may be
used. It is recommended that Bard Return Air Grille Kit
RG2 through RG5 or RFG2 through RFG5 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.
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 one 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.
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 any tags and/
or labels attached to the equipment.
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.
DUCT WORK
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.
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.
SHIPPING DAMAGE
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.

INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1. Two holes for the supply and return air openings must
be cut through the wall as shown in Figure 1.
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.
WARING
Fire hazard can result if 1/4 inch clearance to
combustible materials for supply air duct is not
maintained. See Figure 2.
3. Concrete block walls must be thoroughly inspected to
insure that they are capable of carrying the weight of
the installed unit.
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, but is not required.
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 2 and 3 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 causing damage, injury or death.
3. Locate and mark lag bolt locations and bottom
mounting bracket location. See Figure 2.
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 2.
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
control panel and heat strips, and to allow proper
airflow to the outdoor coil. Additional clearance may
be required to meet local or national codes.

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 muse conform to NEC and all
local codes.
The electrical data lists fuse and wire sizes (75° C
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.
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
convert for the locking capability, bend the tab locate 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
preventingentry.
Five (5) wires should be run from thermostat subbase to
the 24V terminal board in the unit. A five conductor, 18
gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in
Figure 7:
See “Start Up” section for important information on three
phase scroll compressor start ups.
WIRING – LOW VOLTAGE WIRING
230 / 208V, 1 phase and 3 phase equipment dual primary
voltage transformers. All equipment leaves the factory
wired on 240V tap. For 208V operation, reconnect from
240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:
TAP RANGE
240 253 –216
208 220 –187
NOTE: The voltage should be measured at the field
power connection point in the unit and while the
unit is operating at full load (maximum
amperage operating condition).

START UP
IMPORTANT INSTALLER NOTE
For improved start up performance wash the indoor coil
with a dish washing detergent.
CRANKCASE HEATERS
These units are not provided with crankcase heat. These
units utilize scroll compressors which do not require
crankcase heat in this application.
HIGH PRESSURE SWITCH
The 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.
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 rotation, as well as, substantially
reduced current draw compared to tabulated values.
Verification of proper rotation must be made at the time
the equipment is put into service. 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.
The direction of rotation of the compressor may be
changed by reversing any two line connections to the
unit.
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. Switching to heating cycle at 75° F or higher outside
temperature may cause a nuisance trip of the remote
reset high pressure switch. Turn thermostat off then
on to reset the high pressure switch.
3. Check all power fuses or circuit breakers to be sure
they are the correct rating.
4. Periodic cleaning of the outdoor coil to permit full
and unrestricted airflow circulation is essential.
SEQUENCE OF OPERATION
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 of
constant air circulation. On all 230 volt units there is a
one minute off delay on the blower motor. 460 volt
models do not have an off delay.
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.
During routine operation of the unit with no power
interruptions the compressor will operate on demand with
no delay.

Manual 2100-359
Page 14
PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all
units so that the system operating pressures can be
observed. A pressure table 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.
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.
PHASE MONITOR
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.
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.
ADJUSTMENTS
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) DOB = 123 second DOM
1.0 minute (60 seconds) DOB = 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 No. 1: DOB set at 2 minutes, and DOM is 132
seconds
Unit No. 2: DOB set at 4 minutes, and DOM is 144
seconds
