Loosen six nuts (top and bottom) A

Ensure nuts (C) are not loosened

Use belt tension checker to apply a perpendicular force to one belt at the midpoint of the span

Enter the deflection distance obtained

Use a straight edge from sheave to sheave as reference line to determine the deflection distance from normal position

Record the recommended deflection force for the belt section

Check the belt tension at least two times during the first 24 hours of operation

Gas Connection and Pressure Check

Open the main shut-off valve to admit normal gas pressure to the mains.

Check all joints for leaks using soap solution or other suitable material. NEVER USE A FLAME.

Check for proper compressor rotation

Inspect electrical connection for misphasing

Change the phasing of the Field Line Connection if necessary

Verify scroll compressor operation

Check for similar suction and discharge pressures

Ensure proper supply air blower rotation

Clean all piping of dirt and scale by hammering on the outside of the pipe.

Blow out loose particles from the piping.

Have all gas lines external to the unit been purged of air?

Check the size of the filters needed for the unit
