Air-to-Air Plate Heat Exchangers

WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
WARNING
Hazardous Chemicals!
Coil cleaning agents can be either acidic or highly
alkaline and can burn severely if contact with skin
occurs. Handle chemical carefully and avoid contact
with skin. ALWAYS wear Personal Protective Equipment
(PPE) including goggles or face shield, chemical
resistant gloves, boots, apron or suit as required. For
personal safety refer to the cleaning agent
manufacturer's Materials Safety Data Sheet and follow
all recommended safe handling practices. Failure to
follow all safety instructions could result in death or
serious injury.
To clean air-to-air heat plate exchangers:
1. Disconnect all electrical power to the unit.
2. Wearing the appropriate personal protective
equipment, use a soft brush to remove loose debris
from the faces of the exchanger.
3. Install a block-off to prevent spray from going through
the exchanger and into a dry section of the unit and/or
system ductwork.
4. Mix a high-quality coil cleaning detergent with water
according to the manufacturer's instructions.
Note: If the detergent is strongly alkaline after mixing (PH
8.5 or higher), it must contain an inhibitor. Follow
the cleaning solution manufacturer's instructions
regarding the use of the product.
5. Place the mixed solution in a garden pump-up sprayer
or high-pressure sprayer. If a high pressure sprayer is
used:
a. Maintain minimum nozzle spray angle of 15
degrees.
b. Spray perpendicular to the exchanger face.
c. Use a 40 degree nozzle at least 6 inches from the
face.
d. Do not exceed 1450 psi.
6. Spray the lower sides of the exchanger first, then the
upper sides.
7. Thoroughly rinse both sides of the exchanger and the
drain pan with cool, clean water.

8. Repeat steps 6 and 7 as necessary.
9. Straighten any plate fins that may have been damaged
during the cleaning process.
10. Confirm the drain line is open following the cleaning
process.
11. Allow the unit to dry thoroughly before putting it back
into service.
12. Replace all panels and parts and restore electrical
power to the unit.
13. Be careful any contaminated material does not contact
other areas of the unit or building. Properly dispose of
all contaminated materials.

Coils

All coils should be kept clean to maintain maximum
performance.
