PRE-START-UP

WARNING: Failure to observe the following warn- ings could result in serious personal injury:

1.Follow recognized safety practices and wear pro- tective goggles when checking or servicing refrig- erant 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 all electrical sources have been disconnected.

4.Remove and reclaim refrigerant from system be- fore touching or disturbing anything inside termi- nal 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. Sys- tem contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows:

a.Shut off electrical power to unit.

b.Remove and reclaim refrigerant from system.

c.Cut component-connecting tubing with tubing cutter and remove component from unit.

d.Carefully unsweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch ¯ame.

Proceed as follows to inspect and prepare the unit for initial start-up:

1.Remove all access panels.

2.Read and follow instructions on all WARNING, CAU- TION, and INFORMATION labels attached to, or shipped with, unit.

3.Make the following inspections:

a.Inspect for shipping and handling damages such as broken lines, loose parts, disconnected wires, etc.

b.Inspect for oil at all refrigerant tubing connections and on unit base. Detecting oil generally indicates a refrigerant leak. Leak-test all refrigerant tubing connections using electronic leak detector, halide torch, or liquid-soap solution.

c.Inspect all ®eld- and factory-wiring connections. Be sure that connections are completed and tight.

d.Inspect coil ®ns. If damaged during shipping and handling, carefully straighten ®ns with a ®n comb.

4.Verify the following conditions:

a.Make sure that condenser-fan blades are correctly positioned in fan ori®ces. Blades should clear fan motor and fan ori®ce ring.

b.Make sure that return-air ®lters and outdoor-air inlet screens are in place.

c.Make sure that the condensate trap is ®lled with water to ensure proper drainage.

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

5.Loosen the compressor holddown bolts until sideways movement of the washer under each holddown bolt can be obtained. Do not loosen completely as bolts are self- locking and will maintain adjustment. Open compres- sor valves.

6.Make sure refrigerant service port caps are tight. Each refrigerant system has one suction port located in the top of the compressor motor casing. All units also have one service port on the liquid line valve and one on the compressor discharge valve.

7.Crankcase heaters are energized as long as there is power to the unit, except when the compressors are operating.

IMPORTANT: Unit power must be on for 24 hours prior to start-up. Otherwise, damage to compressor may result.

8.Ensure that the suction, discharge, and liquid line serv- ice valves are open. Damage to the compressor could result if they are left closed.

9.Check Direct Digital Controls DIP (dual-in-line pack- age) switch con®guration. The Direct Digital Control (DDC) board must be con®gured for each applica- tion. The DDC board is con®gured through the DIP switches located on the board. There are 8 DIP switches which con®gure 8 different applications of the DDC. See Table 4. DIP switch 1 is on the left of the block. DIP switch 8 is on the right of the block. To open a DIP switch, push the switch up with suitable tool (small- blade screwdriver). To close a DIP switch, push the switch down. Factory settings are shown in Table 5.

The DIP switch con®gurations for the unit control soft- ware are as follows:

·DIP switch 1 should be set to closed (CV operation)

·DIP switch 2 should be set to closed (thermostat)

·DIP switch 3 is used to enable expansion board operation

·DIP switch 4 is used to ®eld test the unit

·DIP switch 5 is used to specify the type of power exhaust
