Pull the drawer to the fully withdrawn position. Inspect the moving and primary and secondary contacts and the static ground contacts. Clean the contact surfaces, removing any burn or pit marks if required. Use an abrasive pad such as Scotch Brite.

Remove the current limiting fuses, and inspect the fuse clip and fuse contact surfaces. Check the transformer for indication of insulation deterioration. Tighten all hardware, including the secondary contact wiring terminals.

Vacuum the compartment and drawer. Wipe off the insulation and control power transformer with a clean, dry cloth.

Lightly lubricate the moving primary and secondary contacts and fingers with Mobilux EP 1, Square D part number 1615-100790.

Lubricate all rollers and sliding parts with Mobil grease 28, Square D part number1615-100950.

Inspect the interlock mechanism for proper operation. Replace the current limiting fuses, but leave the drawer in the withdrawn position until all the inspection and maintenance is completed.

Re-energizing:

Insert all of the circuit breakers to the test/disconnected position with their secondary control power plugs engaged, and close the compartment doors. Connect the control power source.

Close the main source of power, and operate each circuit breaker electrically in the test/disconnected position.

If all controls are functioning properly, disconnect the secondary control plugs. Rack the circuit breakers into the connected position. Close the circuit breakers and resume normal operation.

Description: AIR HANDLING UNIT

Frequency: Quarterly 1Estimated Time (hours):AH01QUCode:

On direct expansion units, use a halogen leak detector or similar device to inspect all refrigerant lines, fittings, and valves for leaks. Correct any leaks.

Check refrigerant level, add as necessary.

Inspect condition of cooling and reheat coils. If required, use fin comb to straighten fins.

Clean coils. Use detergent or coil cleaning solution if heavily soiled. CAUTION: Use appropriate PPE when handling cleaning products.

Drain and clean humidifier pad or pan, if equipped. Replace pad if necessary. Remove corrosion as required.

With power OFF, tighten, inspect all electrical connections for tightness, wiring for damaged insulation, etc. 11 Inspect and adjust vibration isolators.

Run Air Handler. Observe action of controls, relays, switches, etc. Insure that:

Humistat activates humidifier.

Re-heat coils operate properly.

Discharge air temperature is set properly.

Assure that Pre heat controls and safety cutout controls are within operating guidelines.

Double check evaporator coil operation using the pressure - temperature relationship chart & suggested superheat scale.

Inspect and adjust vibration isolators.

Remove tags, perform operational tests, and return to service.
