PRE-STAR%UP
z_ WARNING: Failure to observe the following warnings could result in serious personal injury:
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 terminam cover until all emectrical sources are disconnected.
4. Relieve and recover aH refrigerant from system before touching or disturbing anything inside terminal box if refrigerant
Beak 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 oil and refrigerant under pressure. To remove a component,
wear protective goggles and proceed as folmows:
a. Shut off electrical power to unit.
b. Relieve and reclaim aim 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. Oim can ignite when exposed to torch flame.
Proceed as fbllows to inspect and prepare the unit fbr initial starmp:
1 Remove access panel
2. Read and follow instructions on all WARNING, CAUTION, and INFORMATION labels attached to, or shipped with, uniL
3. Make the following inspections:
a. Inspect fbr shipping and handling damages such as broken lines, loose parts, disconnected wires, etc.
b. Inspect fbr oil at all refrigerant tubing connections and on unit base. Detecting oil generally indicates a refrigerant leak. Leak test all
refi'igerant tubing connections using electronic leak detector, halide torch, or liquid-soap solution. If a refi'igerant leak is detected, see
(?beck for Refi'igerant Leaks section.
c. Inspect all field- and fhctoryowiring connections. Be sure that connections are completed and tight.
d. Ensure electrical wiring does not contact refrigerant tubes or sharp metal edges.
e. Inspect coil fins. If damaged during shipping and handling, careffdly straighten fins with a fin comb.
Verif) the fbllowing conditions:
a. Make sure that condenser-fan blade is correctly positioned in fhn orifice. Leading edge of condenser-fan blade should be 1/2 in.
naaxinmm from fan orifice (See Fig. 1i)_
b. Make sure that air filter(s) is in place.
c. Make sure that condensate drain tlap is filled with water to ensure proper &ainage.
d. Make sure that all tools and miscellaneous loose parts have been removed.

F. CHECK FOR REFRIGERANT LEAKS
Proceed as fbllows to locate and repair a refi'igerant leak and to charge the unit:
1 Locate leak and make sure d-_atrefi'igerant system pressure has been relieved and reclaimed fiom both high- and tow-pressure ports

2 Repair leak following accepted practices. NOTE: Install a filter drier whenever tl-le system has been opened for repair.
3 Add a small charge of Ro22 refrigerant vapor to system and leakotest unit.
4. Recover refl'igerant f?om refi'igerant system and evacuate to 500 microns if no additional leaks are not found.
5. (;barge unit with R-22 ref?igerant, using a volumetric-charging cylinder or accurate scale_ R@_' lo zmit rating p/ate/br _'eqz_il'ed cha_ve.
Be sure to add extra refi'igerant to compensate for internal volume of filter drier.
START UP COOLmNG SECTmON AND MAKE ADJUSTMENTS
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.
