Special Instructions:

1.  Schedule shutdown with operating personnel, as needed.
2.  Review manufacturer's instructions.
3.  Review the Procedure for "Controlling Hazardous Energy
4.  Deenergize, lock out and tag electrical circuit(s).
5.  Schedule PM MOTOREL>1HP-A, in conjunction with this guide.

Include the following additional special instructions in cases where the air
handler is equipped with a direct expansion cooling coil:

6.  Comply with the latest provisions of the Clean Air Act and Environmental
    Protection Agency (EPA) regulations as they apply to protection of
    stratospheric ozone.
7.  No intentional venting of refrigerants is permitted.  During the servicing,
    maintenance, and repair of refrigeration equipment, the refrigerant must be
8.  Whenever refrigerant is added or removed from equipment, record the
    quantities on the appropriate forms.
9.  Recover, recycle, or reclaim the refrigerant as appropriate.
10. If disposal of the equipment item is required, follow regulations concerning
    removal of refrigerants and disposal of the equipment.
11. If materials containing refrigerants are discarded, comply with EPA
    regulations as applicable.
12. Refrigerant oils to be removed for disposal must be analyzed for hazardous
    waste and handled accordingly.
13. 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. ___ Check fan blades for dust buildup and clean if necessary.
2. ___ Check fan blades and moving parts for cracks and excessive wear.
3. ___ Check fan RPM against design specifications.
4. ___ Check bearing collar set screws on fan shaft to make sure  they are tight.
5. ___ Check dampers for dirt accumulations, clean as necessary.  Check felt,
       repair or replace as necessary.
6. ___ Check damper actuators and linkage for proper operation.  Adjust linkage
       on dampers if out of alignment.
7. ___ Lubricate mechanical connections of dampers sparingly.
8. ___ Clean coils by brushing, blowing, vacuuming, or pressure washing.
9. ___ Check coils for leaking, tightness of fittings.  On direct expansion
       units, check for refrigerant leaks on all lines, valves, fittings, coils,
       etc., using a halogen leak detector or similar testing device.  If leaks
       are not able to be stopped or corrected, report leak status to supervisor.
10.___ Use fin comb to straighten coil fins.
11.___ Flush and clean condensate pans and drains, remove all rust
       prepare metal and paint.  Consult the Material Safety Data Sheet (MSDS) to
       ensure that the paint lead level is 0.06% or less.  Hose down coils and
       drain pans and wash with an appropriate EPA approved solution approved
       solution.  Treat condensate pans with an EPA approved biocide.
12.___ Check belts for wear and cracks, adjust tension or alignment,  and replace
       belts when necessary.  Multi-belt drives shall only  be replaced with
       matched sets.
13.___ Check rigid couplings for alignment on direct drives, and for  tightness
       of assembly.  Check flexible couplings for alignment  and wear.
14.___ Before heating season (chilled water coils only):  Drain cooling coils;
       blow down to remove moisture; refill with antifreeze and water solution;
15.___ Check freezestat for proper temperature setting and operation.
16.___ Vacuum interior of unit.
17.___ Lubricate fan shaft bearings while unit is running.  Add grease slowly
       until slight bleeding is noted from the seals.  Do not over lubricate.
       Remove old or excess lubricant.
18.___ Clean up work area.
