York Single Package Cooling Unit ZE060E12B2A1ABA1E1

Inspect unit for possible damage during transit

Note extent of damage on carrier’s freight bill if damage is evident

Request inspection by the carrier’s agent in writing

Ensure compliance with installation instructions and applicable codes

Disconnect furnace and shut-off valve from gas supply piping system for pressure testing above 1/2 PSIG

Replace gas valve if subjected to pressure greater than 1/2 PSIG

Isolate furnace from gas supply piping system by closing manual shut-off valve for pressure testing at or below 1/2 PSIG

Ensure no open flames are present in the area.

Use only approved pipe dope for assembling pipes.

Approved compounds for pipe assembly

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

Prepare a commercially available soap solution for leak detection.

Check all joints for leaks using the soap solution.

Check the number and size of filters needed for the unit

Verify that filters are installed ahead of the evaporator coil

Ensure panel latches are properly positioned to maintain an airtight seal

Confirm the unit is not operated without filters properly installed

Loosen six nuts (top and bottom) A

Ensure nuts (C) are not loosened

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

Enter the deflection distance obtained

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

Record the recommended deflection force for the belt section

Was the belt tension checked at least two times during the first 24 hours of operation?

Check for proper compressor rotation

Verify blower rotation direction

Electrical Connection Verification

Inspect electrical connection for correct phasing

Change the phasing of the Field Line Connection if necessary

Check if scroll compressor is drawing low amperage

Verify suction and discharge pressures are similar
