RECEBVmNGANDINSTALLATION
PROCEDURE 1--CHECK EQUIPMENT
A. BDENTmFYUNmT
The unit model number and serial number are stamped on the unit identification plate. (heck this infbm_ation against shipping papers. -Veril}' that
unit voltage and amperage tisted on unit rating plate agree with power supplied tbr equipment.
B. BNSPECT SHPMENT
Inspect fbr shipping damage while unit is still on shipping pallet. It"unit appears to be damaged or is torn loose fi'om its securing points, have it
examined by transportation inspectors beibre removal. Fop.yard claim papers directly to transportation company. Manu_tcturer is not responsible
fbr any damage incurred in tlansit.
(beck all items against shipping tist. Immediately notify the nearest Payne Air Conditioning ofi[lce if"any item is missing
To prevent loss or damage, 1cave all parts in original packages until installation
PROCEDURE 2--PROVmDE UNiT SUPPORT
A, SLAB MOUNT
Place the unit on a rigid, level surplice, suitable to support the unit weight. A concrete pad or a suitable fibe*glass mounting pad is recommended
The flat su*_hce should extend approximately 2=in beyond the unit casing on the 2 sides The duct connection side and condensate &ain connection
sides should be flush with the edge of the flat surface.
A 6-in. wide gravel apron should be used around the flat surfitce to prevent airflow blockage by grass or shrubs. Do not secure the unit to the flat
sur_tce except where required by local codes.
The unit should be level to within 1/4 inch. This is necessary fbr the unit &ain to fimction properly.
B. GROUND MOUNT
7he unit may also be installed directly on the ground if local codes pem_it. Place unit on level gronnd prepared with gravel for condensate
discharge.
PROCEDURE a--PROVIDE CLEARANCES
The required minimum sma'ice clearances and clearances to combustibles are shown in Fig. 2-4. Adequate ventilation and outdoor coil air must
be provided.
The outdoor fire pulls air through the outdoor coil and discharges it through the fan on the top cover. Be sure that the _hn discharge does not
recirculate to the outdoor coil. Do not locate the unit in either a corner or under an overhead obstruction. The minimum clearance under a partial
overhang (such as a normal house ovmhang) is 48 in. above the unit top. The maxin-mm horizontal extension of a partial overhang must not exceed
48 inches.
Do not place the unit whine water, ice, or snow fiom an overhang or roof will damage or flood the unit The unit may be installed on wood flooring
or on Class A, B, or ( roof cove*lug materials.
A CAUTION: Do not restrict outdoor con airflow. An air restriction at either the outdoor-air inlet or the fan discharge can
be harmful to compressor life.
PROCEDURE 4--PLACE UNBT
Lnit can be moved with the rigging holds provided in the unit base Refer to Table 1%r operating weights. Use extreme cazltinn tn prevent dare, age
_hes_ mo_,is_g the _mit. Uvit m_/st remai_ i_ a_ _lzn'ig,ht fln,sitio'n d_frmg ale mo_mg ope_'ation,s. The unit must be level with in 1/4" for proper
condensate &ainage; the ground-level pad must be level befbre setting the unit in place. When a field-[Sbricated support is used, be sure that the
support is level and that it properly supports the unit.
PROCEDURE 5--SELECT AND mNSTALL DUCTWORK
7he design and installation of the duct system must be in accordance with:
the standards of the NFPA (National Fire Protection Association) [br installation of nonresidence-type air conditioning and ventilating systems
NFPA90A or residence-type, NFPA90B: and/or local codes and residence=type, NFPA 90B
and/or local codes and ordinances
Select and size ductwork, supply=air registers and return-air grilles according to ASHRAE (American Society of Heating, Refrigeration, and Air
Conditioning Engineers) recommendations.
Use the duct flanges provided on the supply° and returnoair openings on the side of the unit. See Fig. 2-4 _br connection sizes and locations. The
14=in. round duct collars (size 024-048 units) are shipped inside t!-_eunit attached to the indoor blower. They are field-installed and must be
removed t'rom the indoor cavity prior to start-up, even if they are not used for installation.
A. BNSTALL FLANGES FOR DUCTWORK CONNECTIONS (PHIZ060 ONLY)
The PH1Z060 units are shipped with _'langes which must be field=installed on the unit.
To install unit flanges:
1. Five pieces of flange are shipped on the return=air opening of the unit Remove the flanges fiom the shipping position (See Fig. 5). Screws
are field°supplied.
2. One piece of flange is used as it is shipped (stlaight) Bend the other 4 pieces at right angles
3. Install the stlaight flange on the right side of the return°air opening in holes provided. (See Fig 6). Flanges should stick out from unit to
allow for connection of dnctwork.
6
4 Install2 hando%m_ed flanges onto return air opening in holes provided to %m_ a rectangle aronnd the remm air opening
5 Install remaining 2 handoformed flanges around discharge air opening in holes provided
6. Ductwork can now be attached to flanges.
When designing and installing ductwork, consider the following:
L,_ CAUTION: When connecting ductwork to units, do not drii[ deeper than 3/4 inch in shaded area shown in Fig. 7 or coi[
may be damaged.
* All units should have field-supplied filters installed in the returnoair side of the unit. Recommended sizes %r filters are shown in Table 1.
Avoid abrupt duct size increases and reductions. Abrupt change in duct size adversely affects air per_bm_ance.
mMPORTANT: Use flexible connectors between dnctwork and unit to prevent transmission of vibration. Use suitable gaskets to ensure
weathertight and airtight seal. When electric heat is installed, use fire proof canvas (or similar heat resistant material) connector between ductwork
and unit discharge connection. If flexible duct is used, insert a sheet metal sleeve inside duct. Heat resistant duct connector (or sheet metal sleeve)
must ectend 24 in. fi'om d_e unit discharge connection flange into the dt/ctwork.
* Size ductwork tbr cooling air quantity (cfm). The mininmm air quanti w for proper electric heater operation is listed in Table 2. Heater limit
switches may trip at air quantities below those recommended.
* Insulate and weatherproof all external dnctwork. Insulate and cover with a vapor barrier all ductwork passing through conditioned spaces.
Follow latest Sheet Metal and Air Conditioning Contractors National Association (SMACNA) and Air Conditioning Contractors Association
(A(CA) minin-mm installation standards for residential heating and air conditioning systems.
* Secure all dt_cts to building structure. Flash, weatherproofS, and vibration-isolate duct openings in wall or roof according to good construction
practices.

B. CONVERTING HORIZONTAL DISCHARGE UNITS TO BOWNFLOW {VERTICAL) DISCHARGE
A WARNBNG: Before performing service or maintenance operations on system, turn off main power to unit and install
lockout tag. Turn off accessory heater power switch if applicabme. Emectrical shock can cause serious injury or death.
Lnits are dedicated side supply products. They are not convertible to vertical air supply A fieldosupplied plenum must be used to convert to vertical
air discharge.
PROCEDURE g--PROVIDE FOR CONDENSATE DISPOSAL
NOTE: Be sure that condensate-water disposal methods comply with local codes, restrictions, and practices.
Unit removes condensate through a 1 3id4oin. ID hole (using 3/4oin. OD piping or tubing) which is located at the end of the unit. See Fig. 2=4
for location of condensate connection.
Condensate water can be drained directly onto the roof in rooftop installations (where pei_aitted) or onto a gravel apron in groundotevel
installations. Install a fieldosupplied condensate tlap at end of condensate connection to ensure proper &ainage. Make sure that the outlet of the
trap is at least 1 in. lower dtan the &ain-pan condensate connection to prevent the pan fi'orn overflowing. Prime the trap with water. When using
a gravel apron, make sure it slopes away fi'om the unit.

COMPRESSOR ROTATION
--[--
THERMOSTAT UNIT CONTROL POWER
AND SUBBASE SPLICE BOX
C99056
On 3 Phase units it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotating
in the proper direction:
1. Connect service gages to suction and discharge pressure fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up.
[f the suction pressure does not &op and the discharge pressure does not rise to normal levels:
1. Turn off power to the unit and tag disconnect.
2. Reverse any [wo of the unit power leads.
3. Turn on power to the unit.
The suction and discharge pressure levels should now move to their normal start-up levels.
NOTE: When the compressor is rotation in the wrong direction, the unit makes an elevated level of noise and does not provide cooling.
PROCEDURE 3--REFRIGERANT CHARGE
Refrigerant (harge Amount of refrigerant charge is listed on unit nameplate and in Table I. Re_I [o Payne Ret'rigerant Service Techniques
Manual, Refrigerants section. Unit panels must be in place when unit is operating during charging procedure. Unit must operate a minin_um of
15 minutes befbre checking charge.
A. NO CHARGE
RefeI to Payne Ret'rigerant Service Techniqnes Use standard evacuating techniques. At'ter evacuating system_ weigh in the specified amount of"
refi'igerant (refer to Table 1).
B. LOW CHARGE COOLmNG

normally used (harts are based on charging the units to the con'ect superheat [br the various operating conditions An accurate pressure gage and
temperature-sensing device is required Connec_ the pressure gauge to the service port on the suction line Connect temperature sensing device to
the suction line near the compressor and insulate it so 4]at outdoor ambient temperature does not affkct reading.
C. TO USE THE COOLING CHARGING CHART
This method is to be used in cooling mode only. Take the outdoor ambient temperature and read the suction pressure gauge. Refer to charts to
determine what the suction temperature should be. If suction temperature is high, add refrigerant. If suction temperatore is low, carefully recover
some of the charge. Recheck the suction pressure as charge is adjusted.

PROCEDURE 5--UNBT CONTROLS
All compressors have the fbllowing internal-protection controls.
A. HGH-PRESSURE RELIEF VALVE
This valve opens when the pressure differential between the low and high side becomes excessive (024 size has temperature relief only)
B. LOSS OF CHARGE SWITCH
Located on the outdoor liquid line is a low-pressure switch which functions as a loss-of-charge switch This switch contains a Schrader core
depressor, This switch opens at 7 psig and closes at 22 psig No adiustment is necessa W
C. COMPRESSOR OVERLOAD
This overload interrupts power to the compressor when either the cmrent or internal temperature become excessive, and automatically resets when
the internal temperature &ops to a safe level. This overload may require up to 60 minutes (or longer) to reset; therefbre, if the internal overload
is suspected of being open, disconnect the elecnical power to the unit and check the circuit through the overload with an ohmmeter or continuity
tester.
PROCEDURE 6--SEQUENCE OF OPERATION
A. FAN OPERATION
_he FAN switch on the thermostat controls indoor fhn operation. When the FAN switch is placed in the ON position, the IFR (indoor-fan relay)
is energized through the G terminal on the thermostat The normally-open contacts close, which then provide power to the indoor (evaporator) _m
motor (IFM) The IFM will run continuously when the FAN switch is set to ON
When the FAN switch is set to AUTO, the thermostat deenergizes the IFR (provided there is not a call fbr cooling). The contacts open and the
IFM is deenergized The IFM will be energized only when there is a call for cooling, in heat pmnp heating mode or if the unit is equipped with
accesso_ electric heat, the indoor=tim motor will also run while the accessory electric heat is energize&
NOTE: Some units are equipped with a time-delay relay On these units, the indoor ihn remains on i\_r 30 seconds after G or Y is deenergized
B. COOLING
With the thermostat snbbase in the cooling position, the thermostat makes circuit R-O This energizes the reversing vah-e solenoid (RVS) and
places the unit in standby condition for cooling.
NOTE: The defrost control board has a 5 minute compressor anti-short cycle time delay built in between compressor starts.
On a call for cooling, the compressor contactor (C) and d_e IFR are energized through the Y and G terminals of the thermostat Energizing the
compressor contactor supplies power to the compressor and the outdoor (condenser) tim motor (OFM) Energizing the IFR provides power to the
IFM.
When the need for cooling has been satisfied, the OFM, compressor, and IFM (FAX' on AUTO) are deenergized. If the unit is equipped with a
30-second delay (036 size only), the indoor fan will remain energized ibr 30 seconds after the compressor is deenergized The reversing valve
solenoid remains energized
C. HEAT PUMP HEATING
On a call fbr heat, thermostat makes circuits R-Y and R-G. Vv'hen compressor time delay (5-minute ÷ 2 minutes) is completed, a circuit is made
to C, starting COMP and OFM. (ircuit R-G also energizes IFR and starts IFM after 1-second delay.

NOTES:
1. In compliance with NEC (National Electrical Code) requirements
for multimotor and combination toad equipment (refer to NEC
Articles 430 and 440), the overcurrent protective device for the
unit shall be Power Supply fuse. Canadian units may be
fuse or circuit breaker.
2. Minimum wire size is based on 60 C copper wire. If other than
60 C wire is used, or if tength exceeds wire length in table,
determine size from NEC.
3. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply volt-
age is greater than 2%. Use the following formula to determine
the percentage of voltage imbalance.
% Voltage imbalance
= 100 x max vottage deviation from average voltage
average vottage
EXAMPLE: Supply voltage is 460-3-60.

BC = 464 v
AC = 455 v
Average Voltage =
452 + 464 + 455

= 457
Determine maximum deviation from average voltage.
(AB) 457 452=5v
(BC) 464 457=7v
(AC) 457 455=2v
Maximum deviation is 7 v.
Determine percent of 'voltage imbalance.
7
% Voltage Imbalance = 100 x --
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is
more than 2%, contact your local etectric utility company
immediate@.

D. DEFROST
Defi'ost board (DB) is a time and temperature control, which includes a fiekl-selectable time period between checks for defrost (30, 50 and 90
minutes). The time period is [hctory=set at 30 minutes and should only be adjusted by a trained service person. Electronic timer and defi'ost cycle
start only when contactor is energized and defrost thermostat (DFT) is closed.
Del:i'ost mode is identical to Cooling mode. The outdoor fan motor stops because of "OFF' and "OFT' contacts opening on the deJi'ost board, a
bank of optional electric heat turns on to warm air supplying the conditioned space.
E. ELECTRIC RESISTANCE HEATmNG
If accesso! 2- electric heaters are installed, on a call _i_)r"Emergency Heat" the thermostat energizes W which energises the heater relay and in turn
energizes the electric heaters. The IFR is energized which starts the indoor-fan motor. If the heaters are stage& W2 is energized when the second
stage of heating is required. When the need for heating is satisfied, the heater and IFM are deenergized.
MAINTENANCE
To ensure continuing high perfbm_ance, and to reduce the possibility of prenmmre eqtdpment failure, periodic nmintenance must be performed
on this equipment. This cooling unit should be inspected at least once each year by a qualified sela'ice person. To troubleshoot cooling of units,
refer to Troubleshooting chart in back of book.
