RECEBVmNGANDINSTALLATION
PROCEDURE 1--CHECK EQUIPMENT
A. BDENTmFYUNmT
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.
