These units will be associated with ACUNITSS-A, ACUNITPU-A, and ACUNITPU-M
packaged air conditioning units, CHILLRWTRCCC-Q refrigeration units, or in the
case of free cooling, would stand alone.

Special Instructions:

1.  Schedule outage with operating personnel.
2.  Obtain and review manufacturer's instructions for starter to be tested
    (including the time current characteristic curve).
3.  Review the Procedure for "Controlling Hazardous Energy
4.  Review the Procedure for "Selection, Care, and Use of
    Respiratory Protection."
5.  Deenergize, tag, and lock out circuit.

Dry Cooler Items to Check & Initial Completion:

1. ___ Remove debris from air screen and clean underneath unit.
2. ___ Pressure wash coil with coil cleaning solution.  Check the Material Safety
       Data Sheets (MSDS) to ensure that the coil cleaner does not contain
       hydrofluoric acid or another irritating or hazardous compound.
3. ___ Straighten fin tubes with fin comb.
4. ___ Check electrical connections for tightness.
5. ___ Check mounting for tightness.
6. ___ Check for corrosion.  Clean and treat with rust inhibitor and touch up
       paint as needed.  Consult the MSDS for hazardous ingredients and proper
       personal protective equipment (PPE).

Motors and Fans Items to Check & Initial Completion:

1. ___ Inspect pulleys, belts, couplings, etc.; adjust tension and tighten
       mountings as required.  Change badly worn belts.  Multi-belt drives should
       be replaced with matched sets.
2. ___ Perform required lubrication and remove old or excess lubricant.
3. ___ Clean motor with vacuum or low pressure air (less than 40 psi).  Check for
       obstructions in motor cooling and air flow.

Expansion Tank Items to Check & Initial Completion:

1. ___ Examine exterior of tank, including fittings, manholes, and handholes for
       leaks, signs of corrosion.  Repair/paint as necessary.
2. ___ Inspect structural supports and repair or replace damaged insulation or
3. ___ Clean, test, and inspect sight glasses, valves, fittings, drains, and
4. ___ Perform hydrostatic test if required.
5. ___ Check antifreeze level with hydrometer and add glycol base antifreeze as
       required for protection to minus 40 degrees Fahrenheit.

Electrical Controls Items to Check & Initial Completion:

1. ___ Visually inspect for broken parts, contact arcing, or any evidence of
2. ___ 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.)
3. ___ Check line and load connections and heater mounting screws for tightness.
