CONDSRUR-A Condensing Unit, Refrigeration -Annual

                                            50 Tons & Under Man Hours 5.5
                                               Over 20 Tons Man Hours 7


This applies to those units that have the compressors located inside
the air cooled condenser housing.  These units are considered one-half of a split
system.  Normally installed where compressor noise and/or vibration is
undesirable and normally associated with air handlers (PM AIRHNDL-A), air
conditioning machines (PM ACUNITSS-A), and modular A/C units, ceiling/wall
mounted, split system (PM ACUNITCW-A).  The unit may stand alone and be
associated with walk-in freezers and refrigerators.

Special Instructions:

The frequency of maintenance for these units will be the same frequency as is
established for the air handler or packaged A/C unit it services.  Normally, once
yearly for air handlers and comfort cooling A/C units and monthly for special
purpose A/C units.

Comfort cooling units should be serviced just prior to the cooling season.

1.  Schedule outage with operating personnel.
2.  Review the Procedure for "Controlling Hazardous Energy
3.  Obtain and review manufacturer's instructions.
4.  Review the Procedure for "Selection, Care, and Use of
    Respiratory Protection".
5.  Deenergize, tag, and lock out electrical circuit.
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 item.
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. ___ Remove debris from air screen and clean underneath unit.
2. ___ Pressure wash coil with coil cleaning solution.  Rinse and neutralize
       (cleaning solution) in accordance with manufacturer's recommendations.
3. ___ Straighten fin tubes with fin comb.
4. ___ Check electrical connections for tightness.
5. ___ Check mounting for tightness.
6. ___ Check all refrigeration lines for support and signs of wear.
7. ___ Thoroughly inspect and clean interior and exterior of machine.
8. ___ Clean and treat all rusted areas.  Touch up prime and paint as needed.
9. ___ Check for refrigerant leaks using a halogen leak detector, soap bubbles,
       or similar testing device.  If leaks are not able to be stopped or
       corrected, report leak status to supervisor.
10.___ Check refrigerant levels and recharge if needed.
11.___ Perform required lubrication and remove old or excess
12.___ Clean motor with vacuum or low pressure air (less than 40
       psi).  Check for obstructions in motor cooling and air flow.
13.___ Visually inspect fused disconnect switches and contactors for condition,
       proper operation, arcing or any evidence of overheating.
14.___ Check motor name plate for current rating and controller
       manufacturer's recommended heater size.  (Heater size shall not be changed
       without the Regional Design Engineer's approval.)
15.___ Check line and load connections and heater mounting screws
       for tightness.
16.___ Check fan blades for dust buildup and clean if necessary.
17.___ Check fan blades and moving parts for excessive wear.
18.___ Check fan RPM to design specifications.
19.___ Check bearing collar set screws on fan shaft to make sure they are tight,
       if applicable.
20.___ Check dampers for dirt accumulation.  Check felt; repair or
       replace as required.
21.___ Check damper motors and linkage for proper operation.  Adjust linkage on
       vanes if out of alignment, if equipped.
22.___ Lubricate mechanical connections of dampers sparingly, if
23.___ Check compressor oil level (non-hermetically sealed units only) if
       compressor is equipped with a sight glass
24.___ Run machine with service gauge manifold attached, checking action of
       controls, relays, switches, etc. to see that:
    a.___ compressor(s) run at proper settings.
    b.___ controls activate properly.
    c.___ controls activate unit.
    d.___ suction and discharge pressures are proper.
25.___ Check setting on controls and return to normal operation.
26.___ Clean up the work area and properly dispose of debris and waste.

Note:  Seal off all service ports with flare caps.  Report any missing caps or
dust covers.
