1. Disconnect all electrical power to the unit.
2. Wear the appropriate personal protective
equipment (PPE).
3. Access to the coil section of the unit (both sides).
4. Use a soft brush to remove loose debris from both
sides of the coil.
5. Mix a high quality coil cleaning detergent with
water according to the manufacturer’s instructions.
If the detergent is strongly alkaline after mixing (pH
8.5 or higher), it must contain an inhibitor. Carefully
follow the cleaning solution manufacturer’s
instructions regarding product use.
6. Place the mixed solution in a garden pump-up
sprayer or high pressure sprayer. If using a high
pressure sprayer note the following:
•
Maintain a minimum nozzle spray angle of 15°
•
Spray perpendicular to the coil face
•
Protect other areas of the equipment and
internal controls from contact with moisture or
the cleaning solution
•
Keep the nozzle at least six inches from the coil
•
Do not exceed 600 psig

Drain plugs are in the piping below supply and return
header for each coil. Use these plugs to drain the coil
and piping. When draining the coil, open the vents at
the top of the supply and return headers. Also, a drain
plug is at the bottom of the inlet condenser manifold
and in the outlet pipe near the left side of the unit.
Remove these plugs to drain the condensers. Be sure
to open the vent plugs at the top of the condenser inlet
and outlet manifold. See .
When refilling the condenser/waterside economizer
coil system with water, provide adequate water
treatment to prevent the formation of scale or
corrosion.

Condensing water contains minerals that collect on the
condenser tube walls. Cooling towers also collect dust
and foreign materials that deposit in the condenser
tube. The formation of scale or sludge in the condenser
is indicated by a decreased water flow, low
temperature difference between inlet and outlet water,
and abnormally high condensing temperatures. To
maintain maximum condenser efficiency, the
condenser must remain free of built-up scale and
sludge. Clean the condenser either mechanically or
chemically.
1. Disconnect all electrical power to the unit.
2. Wear appropriate personal protective equipment
(PPE).
3. Access both sides of the coil section.
4. Use a soft brush to remove loose debris from both
sides of the coil.
