PRE-START-UP

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

1.Follow recognized safety practices and wear protective goggles when checking or the servic- ing refrigerant system.

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

3.Do not remove compressor terminal cover until all electrical sources are disconnected.

4.Relieve all pressure from system before touch- ing or disturbing anything inside terminal box if refrigerant leak is suspected around compres- sor terminals. Use accepted methods to recover refrigerant.

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

6.Do not use torch to remove any component. The system contains oil and refrigerant under pres- sure. To remove a component, wear protective goggles and proceed as follows:

a.Shut off electrical power to unit.

b.Recover refrigerant to relieve all pressure from system using both high-pressure 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. Oil can ignite when exposed to torch flame.

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, CAUTION, 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 field-wiring and factory-wiring connec- tions. Be sure that connections are completed and tight. Ensure electrical wires do not come in con- tact with refrigerant lines or sharp edges.

d.Inspect coil fins. If damaged during shipping and handling, carefully straighten fins with a fin comb.

4.Verify the following conditions:

a.Make sure that condenser-fan blade is positioned correctly in fan orifice. Blades should clear fan motor and fan orifice ring.

b.Make sure that air filters are in place. (See Tables 1A and 1B.) Do not operate unit without return-air filters.

c.Make sure that the condensate drain pan and trap are filled with water to ensure proper drainage.

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

e.Make sure outdoor-air inlet screens are in place.

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

6.Each unit system has 3 Schrader-type service ports: one on the suction line, one on the liquid line and one on the compressor discharge line. Be sure that caps on the ports are tight.

7.Ensure electrical wires do not make contact with refrigerant lines.

START-UP

I. UNIT PREPARATION

Make sure that unit has been installed in accordance with these installation instructions and applicable codes. Ensure Start-Up Checklist on back page of booklet is completely filled out.

II. RETURN-AIR FILTERS

Make sure correct air filters are installed in unit (see Tables 1A and 1B). Do not operate unit without return-air filters.

III. OUTDOOR-AIR INLET SCREENS

Outdoor-air inlet screen(s) must be in place before operating unit.

IV. COMPRESSOR MOUNTING

Compressors are internally spring mounted. Do not loosen or remove compressor holddown bolts. Remove the tiedown bands that hold the compressors together on 558F103,121,150,151 units.

V. INTERNAL WIRING

Check all electrical connections in unit control boxes; tighten as required. Verify and correct if necessary. Ensure that elec- trical component wiring does not come in contact with refrig- erant tubing or sharp edges.

VI. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor access panel. Each unit system has 3 Schrader-type service gage ports: one on the suction line, one on the liquid line, and one on the compressor discharge line. Be sure that caps on the ports are tight. The Schrader-type valve on the discharge line is located under the low-pressure switch. Another valve is located on the discharge line underneath the high- pressure switch. It is screwed on a Schrader fitting but there is no Schrader core.

A. High Flow Refrigerant Valves

Two high flow valves are located on the hot gas tube coming out of the compressor and the suction tube going into the compressor. Large black plastic caps identify these valves. These valves have O-rings inside which screw the cap onto a brass body to prevent leaks. No field access to these valves is available at this time. Ensure the plastic caps remain on the valves and are tight or the possibility of refrigerant leakage could occur.

VII. COMPRESSOR ROTATION

On 3-phase scroll compressor units (103,121,150,151), it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotat- ing in the proper direction:

1.Connect service gages to suction and discharge pres- sure fittings.
