The required minimum service clearances are shown in Figs. 2 and 3. Adequate ventilation and outdoor air must be provided. The outdoor fire
&aws air through the outdoor coil and discharges it through the top fun grille. Be sure that the fan discharge does not recirculate to the outdoor

coil. Do not locate the unit in either a comer or under an overhead obstruction. The minimum clearance under a partial overhang (such as a no*real
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.
Do not place the unit where water, ice, or snow from an overhang or roof will damage or flood the unit. Do not install the unit on carpeting or

other comhustible materials. Slab-mounted units should be at least 4 in. above the highest expected water and runoff levels. Do not use unit if it
has been under water.

PROCEDURE 4--RIG AND PLACE UNmT
Rigging and handling of d_is equipment can be hazardous %r many reasons due to the installation location (roofs, elevated structures, etc.)

Only trained, qualified crane operators and ground 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

safety precautions that might apply.
Follow all applicable safety codes. Wear safety shoes and work gloves.

A. mNSPECTION

Prior to initial use, and at monthly intervals, all rigging brackets and straps should be visually inspected for any damagQ evidence of wear,
structural defbm_atiom 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.

B. mNSTALLATION

1. Remove unit from shipping carton Leave top shipping skid on the malt as a spreader bar to prevent the rigging straps from damaging the
unit If the wood skid is not available, use a spreader bar of sufficient length to protect unit f?om damage.

2 Position the lifting bracket assembly around the base of the unit. Be sure the strap does not twist
3 Place each of the 4 metal lifting brackets into the rigging holds in the composite pan

PROCEDURE 5--SELECT AND BNSTALL DUCTWORK

The design and installation of the &/ct system must be in accordance with the standards of [l_e NFPA [br installation of non-residence type air
conditioning and ventilating systems, NFPA 90A or residence type, NFPA 90B and/or local codes and ordinances.

Select and size ductwork, supply=air registers, and remm air grilles according to ASHRAE (American Society of Heating, Refrigeration, and Air
Conditioning Engineers) recommendations.

The unit has duct flanges on the supply- and return-air openings on the side of the unit.
When designing and installing ¢lt/ctwork_ consider the following:

z_ WARNING: For vertical supply and return units, tools or parts could drop into ductwork and cause serious injury or

death. Install a 90 degree turn in the return ductwork between the unit and the conditioned space. If a 90 degree elbow cannot
be installed, then a grille of sufficient strength and density should be installed to prevent objects from falling into the

conditioned space. Units with electric heaters require 90 degree elbow in supply duct.

1. All units shonld have field=supplied filters or accessory filter rack installed in the return-air side of the unit. Recommended sizes %r filters
are sho_xn in Tables 1 and 2

2. A_oid abla/pt duct size increases and reductions. Abrupt change in duct size adversdy affects air performance.

PROCEDURE 7--BNSTALL ELECTRICAL CONNECTIONS

Z_ WARMNG: The unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of

personal injury if an electrical faumtshould occur. This ground may consist of an electrical wire connected to the unit ground
lug in the controJ compartment, or conduit approved for electrical ground when instalmed in accordance with NEC, ANS[/NFPA

American National Standards Institute/National Fire Protection Association {latest edition) (in Canada, Canadian Electrical
Code CSA C22.1) and local electrical codes. Failure to adhere to this warning could result in serious injury or death.

Z_ CAUTION: Failure to follow these precautions could resuR in damage to the unit being installed:

1. Make aH electrical connections in accordance with NEC ANSI/NFPA (latest edition) and local electricam codes governing
such wiring. In Canada, aH electricam connections must be in accordance with CSA standard C22.1 Canadian Electrical

Code Part 1 and applicable Bocal codes. Refer to unit wiring diagram.

2. Use only copper conductor for connections between field-supplied electrica! disconnect switch and unit. DO NOT USE ALUMINUM
WIRE.

3, Be sure that high-voltage power to unit is within operating voltage range indicated on unit rating plate. On 3°phase units, ensure

phases are balanced within 2 percent. Consult local power company for correction of improper voltage and/or phase imbalance.

4, Insulate low-voltage wires for highest voltage contained within conduit when low-voltage control wires are in same conduit as

high-voltage wires.

5, Do not damage internal components when drilling through any panel to mount electrical hardware, conduit, etc,

A. HGH-VOLTAGE CONNECTIONS

The unit must have a separate electrical service with a _ield-supplied., waterproof disconnect switch mounted at, oi"within sight flora the uniL Refer
to the unit rating plate, NEC and local codes for maximum f_/seicircuit breaker size and minimum circuit amps (ampacity) for wire sizing (See

Tables 5 and 6 for electrical data).
The field-supplied disconnect may be mounted on the unit over the high-voltage inlet hole (See Fig 2 and 3).

If the unit has an electric heater, a second disconnect may be required. Consult the Installation, Start=Up, and Service Instructions provided with
the accessory fbr electrical service connections.

Operation of unit on improper line voltage constitutes abuse and may cause unit damage that could aft'oct wa_Tanty.

B. ROUTING POWER LEADS BNTO UNBT

Use only copper wire between disconnect and unit. The high=voltage leads should be in a conduit until they enter the duct panel; conduit
termination at the duct panel must be watertight. Run the high-voltage leads through the power entry knockout on the power entry side panel See

Fig. 2 and 3 t'or location and size. When the toads are inside the unit, run leads up the high-voltage raceway to d_e tine wiring splice box (See Fig

13 19) For single-phase units, connect leads to the black and yellow wires; for 3=phase units, connect the leads to the black, yellow, and blue wires

3.Unbalanced3-PhaseSupplyVoltage

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.

% 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

immediately.

z_ WARNING: Failure to observe the following warnings coumd result in serious personal injury or death:

1. Follow recognized safety practices and wear protective goggles when checking or servicing refrigerant system.

2. Do not operate compressor or provide any electric power to unit unless compressor terminal cover is in place and secured.

3. Do not remove compressor terminal cover until aH electrical sources are disconnected and tagged.

4. Relieve and recover all refrigerant from system before touching or disturbing anything inside terminal box if refrigerant
leak is suspected around compressor terminals.

5. Never attempt to repair soldered connection while refrigerant system is under pressure.

6. Do not use torch to remove any component. System contains oH and refrigerant under pressure.

To remove a component, wear protective goggles and proceed as follows:
a. Shut off electrical power to unit and install mockout tag.

b. Relieve and reclaim aH refrigerant from system using both high- and low-pressure ports.

c. Cut component connecting tubing with tubing cutter and remove component from unit.
d. Carefully unsweat remaining tubing stubs when necessary. OH can ignite when exposed to torch flame.

/se the Start-Up (hecklist supplied at the end of this book and proceed as %llows to inspect and prepare the unit %r initial start-up:

1 Remove access panel,
2 Read and follow instructions on all DANGER, WARNING, (AUTION, and INFORMATION labels attached to, or shipped with, unit,
3 Make the following inspections:

a, Inspect _br shipping and handling damages such as broken lines, loose parts, discom_ected wires, etc,

b. Inspect foI oil at all refrigerant tubing connections and on unit base Detecting oil generally indicates a refrigerant leak. Leak-test all

refiigerant robing connections using electronic leak detector, or liquid=soap solution. Ifa ref'rigerant leak is detected_ see following Check

fbr Refiigerant Leaks section.
c. Inspect all field and fhctory=wiring connections. Be sure that connections are completed and tight.
d. Ensure wires do not touch refrigerant robing or sharp sheetmetal edges.

e. Inspect coil fins. If damaged dr/ring shipping and handling, carefhlly straighten fins with a fin comb.

4. Verify the following conditions:
a. Make sure that outdoor-fan blade is correctly positioned in fire orifice (See Fig. 21).

b. Make sure that condensate drain pan and trap are filled with water to ensure proper &ainage.

c. Make sure that all tools and miscellaneous loose parts have been removed.

5. (ompressors are internally spring mounted. Do not loosen or remove compressor holddown bolts.

6. Each unit system has 2 Schrader=type ports, one tow-side Schrader fitting located on the suction tine, and one high-side Schrader fitting
located on the compressor discharge line. Be sure that caps on the ports are tight.

7. High flow valves are located on the compressor hot gas and suction robes. These valves can not be accessed fbr service in the field. Ensure

the plastic caps are in place and tight or the possibility or refi'igerant leakage could occur.

START-UP

l_sing the Start-Up (hecklist supplied at the end of this book, proceed as %llows:

PROCEDURE I--CHECK FOR REFR{GERANT LEAKS

Locate and repair refi'igerant leaks and charge the unit as fbltows:

1. Use both high- and tow-pressure ports to relieve system pressure and reclaim remaining refi'igerant.

2. Repair leak fbltowing accepted practices.

NOTE: Install a bi=flow filter drier whenever the system has been opened for repair.

3. Check system for leaks using an approved method.

CONTROL OPERATION

Start and check the unit _br proper control operation as follows:

1. Place room thet_nostat SYSTEM switch in OFF position. Observe that blower motor starts when FAN" switch is placed in ON position and
shuts down within (50 sec. when FAN switch is placed in AUTO position.

2. Place SYSTEM switch in COOL position and FAN switch in AUTO position. Set control below room temperature. Observe that cooling
cycle shuts down when control setdng is satisfied.

3. Place system switch in HEAT position. Set control above room temperature. Observe that compressor, outdoor tim, and indoor blower
motors start. Observe that heating cycle shuts down when control setting is satisfied.

4. When using an atttomatic changeover room thermostat, place both SYSTEM and FAN" switches in AUTO positions. Observe that unit
operates in Cooling mode when temperatme control is set to "call for Cooling" (below room temperature), and unit operates in Heating

mode when temperature control is set to "call for Heating" (above room telaperamre).

IMPORTANT: ThreeophasQ scroll compressors are direction oriented. Unit must be checked to ensure proper compressor 3-phase power lead
orientation. If not corrected within 5 minute, the internal protector will shut off the compressor. The 3-phase power leads to the unit must be

reversed to cot_vct rotation. When turning backwards, scroll compressors emit elevated noise levels, and the difference between compressor suction
and discharge pressures may be dramatically lower than normal.

B. CHECKING AND ADJUSTING REFRIGERANT CHARGE

The refrigerant system is fldly charged with R-22 re['rigerant and is tested and fhctory sealed. Allow system to operate a minimum of 15 minutes
bel:bre checking or adjusting charge.

NOTE: Adjustment of the refl'igerant charge is not required unless the unit is suspected of not having the proper R-22 charge. The charging label
and the tables shown re_hr to system temperatures and pressures in cooling mode only. A refiigerant charging label is attached to the outside of

the service access door. If charge level is suspect in Heating mode, reclaim all re['rigerant and charge to nameplate amount. (This inJ:brmation may
be obtained from the physical data table also.)

IMPORTANT: When evaluating the refi'igerant charge, an indicated adjustment to the specified _i_ctoV charge must always be ve_- minimal. If
a substantial adjustment is indicated, an abnom_al condition exists somewhere in the cooling system, such as insu_l]cient airflow across either coil

or both coils.

C. REFRIGERANT CHARGE

The amount of refligerant charge is listed on the unit nameplate and/or the physical data table. Refer to the Refi'igeration Service Techniques
Manual Refi'igerants Section.

D, NO CHARGE

Check for leak. Use standard evacuating techniques, After evacuating system to 500 microns_ weigh in the specified amount of refrigerant (refer
to system data plate)

E. LOW CHARGE COOLmNG

Lse (ooling (harging Charts (Fig. 26-38) Va_- refi'igerant until the conditions of the chart are met Note that charging charts are different fiom
type normally used. (harts are based on charging the units to cot_'ect superheat for the various operating conditions Accurate pressure gage and

temperature sensing devices are required. ( onnect the pressure gage to the service port or* the suction line. Mount the temperature sensing device
on the suction tine and insulate it so that the outdoor ambient does not affect the reading, Indoor air CFM must be within the normal operating

range of the unit

g. TO USE COOLmNG CHARGING CHARTS

qake the outdoor ambient temperature and read d_e suction pressure gage. Refer to the chart to determine what the suction temperature shouk! be.
NOTE: [f the problem causing the inaccurate readings is a refi'igerant leak, refer to Check _br Refrigerant Leaks section.

PROCEDURE 9--LBQUID UNE STRAINERS

7he liquid line strainers (to protect metering devices) are made of wire mesh and are located in the liquid lines on the inlet side of the metering
devices,

PROCEDURE 10--HGH FLOW VALVES

High t]ov,' valves are located on the compressor hot gas and suction tubes. Large black plastic caps distinguish these valves with O-rings located

inside the caps. These valves can not be accessed for sere'ice in the _]eld Ensure the plastic caps are in place and tight or the possibility of

relti"igerant leakage could occur.

PROCEDURE 11--T_ME-DELAY RELAY

The TimeoDelay Relay (TDR) is a solid-state control, recycle delay timer which keeps indoor blower operating %r 60 sec. after thermostat is
satisfied. This delay enables blower to remove residual cooling in coil after compression shu[down_ thereby improving efficiency of system The

sequence of operation is that on closure of wall them_ostat and at end of a fixed on delay of 1 see., fhn relay is energized. When thermostat is
satisfied, an off delay is initiated. When fixed delay of 60÷ 5 sec. is completed, fire relay is de-energized and fhn motor stops. If wall thermostat

closes during this delay, TDR is reset and fan relay remains energized. TDR is a 24-v device that operates within a range of 15-v to 30or and draws
about 0.5 amps. If the blower rnns continuously instead of cycling off when the ['an switch is set on AUTO, the TDR is probably defective and

n-rest be replaced.

PROCEDURE 12--LOSS OF CHARGE SWITCH

The loss of charge switch is located on the outdoor liquid line. This switch contains a Schrader core depressor. This switch opens at 7 psig and
closes at 22 psig. No adjustment is necessary.

NOTE: Because these switches are attached to refrigeration system under pressure, it is not advisable to remove this device for troubleshooting
unless you are reasonably certain that a problem exists. If switch must be remo_ ed, remove and reco_ er all system charge so that pressure gages

read 0 psi. Never open system without breaking vacumn with &y nitrogen.

PROCEDURE 13--CHECK DEFROST THERMOSTAT

There is a liquid header with a brass distributor and f_eder tube going into outdoor coil. At the end of I of the f_eder tubes, there is a 3/8-in. OD
stub robe approximately 3 in. tong (See Fig. 40). The defrost d_ennostat should be located on this stub robe. Note that there is only 1 stub robe

used with liquid header, and on most units it is the bottom circuit.

PROCEDURE 14--DEFROST THERMOSTAT

Defi'ost tl_ermostat signals heat pump that conditions are right for del_-ost or that conditions have changed to terminate defrost. It is a thermally
actuated switch clamped to outdoor coil to sense its temperature. Normal temperature range is closed at 30 _>_/o 3°F and open at 80 _>_/- 5°F

NOTE: The defrost thermostat n-rest be located on the liquid side of the outdoor coil on the bottom circuit and as close to the coil as possible
