PROCEDURE 3--PROMIDE CLEARANCES

_he required minimum service clearauces are shown in Fig. 2 & 3. Adequate ventilation and outdoor air must be provided. The outdoor _m drav,s
air through the outdoor coil and discharges it through the top Jim grille. Be sure that the fan discharge does not recirculate to the outdoor coil. Do
not tocate the unit in either a come* or under an overhead obstruction. The minimum clearance under a partial ore*hang (such as a normal house

overhang) is 36 in above the unit top. The maximum horizontal extension of a partial overhang must not exceed 48 in For extended overhangs,
provide a minimum clearance of 48 in.

mMPORTANT: Do not restrict outdoor airflow, An air restriction at either the outdoor-air inlet or the fan discharge may be detrimental to
compressor life,

PROCEDURE 4--F{ELD FABRBCATE DUCTWORK

Secure all ducts to roof curb and building structure on vertical discharge units, Do vot co_v¢ct d_lcmork to _mit.For horizontal applications, unit
is provided with flanges on the horizontal openings All dnctwork should be secured to the flanges. Insulate and weatherproof all external ductwork,

joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier If a plenum return is used on a vertical unit,
the return should be ducted through the roof"deck to comply with applicable fire codes A mininmm clearance is not required around ductwork_

Cabinet retm'n=air static shall not exceed -.25 in wg

PROCEDURE 5--RIG AND PLACE UNIT

Rigging and handling of this equipment can be hazardous for many reasons due to the installation location (roo_s, elevated structures, etc.)
Only trained, qualified crane operators and grotmd support staff should handle and install this equipment.

When working with this equipment, observe precautions in the literature, on tags, stickers, and labels attached to the equipment, and any other
safkty precautions that might apply.

Follow all applicable safety codes. Wear safety shoes and work gloves.

/_ WARNING: Never stand beneath rigged units or lift over people.

/_ WARNING: Never exceed 200 Ibs. per bracket tilting force.

!_x WARNING: Accessory lifting kit is only to be used with Small Packaged units which have a composite base pan with

molded rigging holds.

A, [NSPECTBON

Prior to initial use. and at monthly intervals, all rigging brackets and straps should be visually inspected for any damage, evidence of wear,
snucmral deibrmation, or cracks. Particular attention should be paid to excessive wear at hoist hooking points and load support areas. Brackets

or straps showing any kind of wear in these areas must not be used and should be discarded.

g. INSTALLATION

1. Position the lifting bracket assembly around the base of the unit. Leave the top shipping skid on the unit to act as a spreader bar. Be sure
the strap does not twist.

2 Place each of the ibur (4) metal lifting brackets into the rigging holds in the composite pan
3_ Tighten the ratchet strap unit tight. Lit'ring brackets should be secure in the rigging holds.

4 Attach the clevis or hook of sufficient strength to hole in the lifting bracket (See Fig 6).
5 Attach safety stlaps directly to the field supplied rigging straps or clevis clip Do not attach the safety straps to the lifting brackets_

6 Use the top of the unit as a spreader bar to prevent the rigging straps from damaging the unit. If the wood top is not available, use a spreader

bar of sufficient length to not damage the unit

z_ WARNING: Lifting point should be directly over the center of gravity for the unit,

PROCEDURE g--CONNECT CONDENSATE DRAIN
NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions.

Models PA 1P and PA2P dispose of condensate water through a 3/4 in. NPT fitting which exits through the base on the evaporator coil access side
See Fig. 2 & 3 for location.

Condensate water can be drained directly onto the roof in rooftop installations (where permitted) or onto a gravel apron in ground=level
installations. Install a field=supplied condensate trap at end of condensate connection to ensure proper &ainage Make sure that the outlet of the

trap is at least 1 in. lower than the drainpan condensate connection to prevent the pan from overflowing (See Fig 7) When using a gravel apron,
make sure it slopes away fi'om the unit.
( onnect a &ain tube using a minin_un_ of 3/4 -in PVC or 3/4 -in. copper pipe (all field-supplied) at the outlet end of the 2-in. trap. Do not undersize

the tube Pitch the &ain robe downward at a slope of at least 1-in for every 10 ft of horizontal 17.m Be sure to check the drain robe for leaks.
Prime t_ap at the beginning of the cooling season start-up.

PROCEDURE 7--INSTALL DUCT CONNECTIONS

]_he unit has duct flanges on the supply- and return=air openings on the side and bottom of the unit For downshot applications the ductwork can
be connected to the roof curb. See Fig. 2 & 3 ibr connection sizes and locations

IMPORTANT: Use flexible connectors between dtlctwork 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)
n-met extend 24°in. tiom the unit discharge connection flange into the ductwork.

A. CONFIGURING UNITS FOR DOWNFLOW (VERTICAL} DISCHARGE

A WARNING: Before performing service or maintenance operations on the system, turn off main power to unit and

install lockout tag or electrical shock could result.

1 Open all electrical disconnects and install lockout tag before starting any smwice work.

2 Remove remm duct cover located on duct panel by breaking four (4) connecting tabs with screw&iver and a hammer. (Fig. 8 & 9)

Z_ CAUTION: Complete the required procedures given in the Pre-Starto Up section before starting the unit. Do not jumper

any safety devices when operating the unit. Do not operate the compressor when the outdoor temperature is below 40°F
(unless accessory Iowoambient kit is installed). Do not rapid-cycle the compressor. AHow 5 minutes between "on" cycles to

prevent compressor damage.

H. CHECKINGCOOLINGCONTROLOPERATION

Start and check the unit %r proper cooling control operation as %llows:

1. Place room thermostat SYSTEM switch in OFF position Obsela'e that blower motor starts when FAN" switch is placed in ON position and
shuts down after 30 second _hn time delay expires when FAN switch is placed in AUTO position.

2. Place SYSTEM switch in COOL position and FAN" switch in AUTO position. Set cooling control below room ternperamre. Observe that
compressor, condenser fan, and evaporator blower motors start. Observe that compressor and outdoor fan shut down when contIol setting

is satisfied and that indoor blower shuts down afier 30 second fire time delay expires.

3. When using an auto-changeover room thel_nostat, place both SYSTEM and FAN' switches in AUTO positions. Obsela-e that unit operates
in heating mode when temperature conhol is set to "call for heating" (above room temperature) and operates in cooling mode when

temperature control is set to "call fbr cooling" (below room temperature).

IMPORTANT: Three-phase, scroll compressor units (PA1P048, PA2P030-060) are direction-oriented. These units must be checked to ensure

proper compressor 3-phase power lead orientation. If not corrected within 5 minutes, the internal protector will shut off the compressor. The

3-phase power leads to the unit must be reversed to correct rotation. When turning backwards, scroll compressors emit elevated noise levels, and

the difference between compressor suction and discharge pressures may be &amatically lower than nom_al.

I. CHECKING AND ADJUSTING REFRBGERANT CHARGE

_fhe refi'igerant system is fldly charged with R-22 refrigerant, tested, and ihctory-sealed.
NOTE: Adjustment of the refrigerant charge is not required unless the unit is suspected of not having the proper R-22 charge.

A superheat charging chart is attached to the outside of the service access panel. The chart includes the required suction line temperature at given

suction line pressures and outdoor ambient temperatures (See Fig. 15 27).

An accurate superheat, thermocouple- or thermistor-type thermometer, a sling psychrometer, and a gauge manifold are required when using the

superheat charging method fbr evaluating the unit charge. Do 1rot _*.seme_'c_¢_?"or .sma/[ dia/-Ope thermometer:_' beca_¢se th<_"are not a&,q_¢ate for
thi.v _379e q/ sneas_lreme_t

NOTE: Allow system to operate in the cooling mode for a minimum of 10 minutes before checking or adjusting refi'igerant charge.

Z_X CAUTION: When evaluating the refrigerant charge, an indicated adjustment to the specified factory charge must

always be very minimal If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling
system, such as insufficient airflow across either coim or both coils.

Proceed as %llows:

1. Remove caps fi'om low- and high-pressure service fittings

2. Using hoses with valve core depressors, attach tow- and high-pressure gauge hoses to low- and high-pressure service fittings, respectively

3. Start unit in Cooling mode and let unit run until system pressures stabilize

4. Measure and record the following:
a. Outdoor arnhient-air temperature (_>F db).

b. Evaporator inlet-air ternperamre (_'F wb).

c. Suction-tube tenlperatme (_'F) at low-side service fitting.
d. Suction (!ow-side) pressure (psig).

5. Using "Cooling Charging Cha_s" compare outdoor-air temperature (°F dfb) with the suction tine pressure (psig) to determine desired system
operating suction line temperature. See Fig. 15-27.

6. Compare actual suction-robe temperature with desired suction-tube temperature. Using a tolerance of ÷3°F, add refi'igerant if actual

temperatt_re is more than 3_>Fhigher than proper suction-robe temperature, or remove refrigerant if acttml temperature is more than 3_>Flower
than required suction-tube temperature.

NOTE: If the problem causing the inaccurate readings is a refi'igerant leak, refer to Check for Refl'igerant Leaks section.

J. INDOOR AIRFLOW AND AIRFLOW ADJUSTMENTS

Z_ CAUTION: For cooling operation, the recommended airflow is 350 to 450 cfm for each 12,000 Btuh of rated cooling

capacity.

Tables 8 and 9 show cooling airt)ows at various external static pressures. Refer to these tables to detem_ine the airflow _br the system being
installed.

NOTE: Be sure that all supply- and return-air grilles are open, free from obstructions, and adjusted properly.

Z_ WARNmNG: Disconnect electrical power to the unit and install lockout tag before changing blower speed. Electrical

shock can cause serious injury or death.

Airflow can be changed by changing the lead connections of the blower motor

M. COOLING SEQUENCE OF OPERATmON

With [l_eroom thermostat SYSTEM switch in the (eel position and the FAN switch in the AUTO position, the cooling sequence of operation

is as fPllows:

When the room temperatnre rises to a point that is slightly above the cooling control setting of the thermostat, the thermostat completes the circuit
between thermostat terminal R to terminals Y and G These completed circuits through the thermostat connect contactor coil (C) (through unit wire

Y) and time delay relay (TDR) (through unit wire G) ac*oss the 24ov seconda W of transformer (TRAN).

The normally open contacts of energized contactor (C) close and complete the circuit through compressor motor (COMP) to condenser (outdoor)
fire motor (OFM). Both motors start instantly.

The set of normally open contacts of energized relay TDR close and complete the circuit through evaporator blower (indoor) fhn motor (IFM)
NOTE: Once the compressor has started and then has stopped, it should not be started again until 5 minutes have elapse&
The cooling cycle remains _on" until the room temperature drops to a point that is slightly below the cooling control setting ot'the roonr thermostat.

At this point, the tl'lcrmostat "breaks" the circuit between thermostat terminal R to terminals Y and G These open circuits deenergize contactor

coil C and relay coil TDR The condenser and compressor motors stop After a 30-second delay, the blowe* motor stops The unit is in a %tandhy"
