Special Instructions:
1. Review manufacturer's instructions and the Procedure for
"Controlling Hazardous Energy Sources."
2. Deenergize, lockout, and tag electrical circuits.
3. Comply with the latest provisions of the Clean Air Act and Environmental
Protection Agency (EPA) regulations as they apply to protection of
stratospheric ozone.
4. No intentional venting of refrigerants is permitted. During the servicing,
maintenance, and repair of refrigeration equipment, the refrigerant must be
recovered.
5. Whenever refrigerant is added or removed from equipment, record the
quantities on the appropriate forms.
6. Recover, recycle, or reclaim the refrigerant as appropriate.
7. If disposal of the equipment item is required, follow regulations concerning
removal of refrigerants and disposal of the equipment.
8. If materials containing refrigerants are discarded, comply with EPA
regulations as applicable.
9. Refrigerant oils to be removed for disposal must be analyzed for hazardous
waste and handled accordingly.
10. Closely follow all safety procedures described in the Material Safety Data
Sheet (MSDS) for the refrigerant and all labels on refrigerant containers.
Items to Check & Initial Completion:
1. ___ Inspect piping for evidence of leaks and vibration. If leaks are not
able to be stopped or corrected, report leak status to supervisor.
2. ___ Inspect all wiring for deterioration, and tighten electrical contacts.
Check for corrosion, clean, prime, and paint as necessary.
3. ___ Check mounting bolts and tighten if needed.
4. ___ Check crankcase heater.
5. ___ Check fan for vibration or excessive noise. Lubricate fan
and motor if required.
6. ___ Check refrigerant levels, recharge if necessary. Check for leaks if loss
of refrigerant is detected, using halide leak detector and soap bubbles.
If leaks are not able to be stopped or corrected, report leak status to
supervisor. Consult the Material Safety Data Sheets (MSDS) for disposal
requirements. Reclaimed and recycled CFCs are exempt from hazardous
waste regulations (Consult 40 CFR Part 261).
7. ___ Check temperature drop across condensing coil.
8. ___ Clean air intake and screens; change filters as necessary.
9. ___ Brush or pressure wash coil surfaces. Straighten fins with
fin comb.
10.___ Check that reversing valve is energized in the "heat" mode
and deenergized in the "cool" mode. Replace defective valves.
11.___ Check all electrical connections and fused disconnect switches.
12.___ Check all controls, indoor and outdoor thermostats, timers, and control
delays, especially for units with electric supplemental heaters. Repair
or replace as necessary.
13.___ Check oil if compressor is equipped with a sight glass.
14.___ Clean up work area.
