Maintenance Procedures

Before beginning any maintenance procedures heed all warnings and cautions.

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.

Periodic Maintenance Checklist

…Inspect coil surface for cleanliness. Clean as required. Refer to “Coil Cleaning” under “Maintenance Procedures.”

Annual Maintenance Checklist

…Perform all monthly maintenance inspections.

…Perform seasonal startup checks.

…Leak test refrigerant circuits. Inspect contacts of fan motor contactors and relays. Replace all worn contacts.

…Clean condenser fans.

…Clean and repaint any corroded surface.

Periodic Maintenance Procedures This section describes specific maintenance procedures that must be preformed as a part of the normal maintenance program for this unit. Be certain to disconnect electrical power to the unit before performing these procedures.

Note: the following coil cleaning proce- dures apply only to the outdoor condens- ers. Do not use these procedures for the reheat or evaporator coils.

Cleaning the Condenser Coils

Clean the coil at least once each year or more frequently if located in a dirty environment, to help maintain proper unit operating efficiency. High discharge pressures are a good indication that the coil needs cleaning. Follow the detergent

manufacturer instructions as closely as possible to avoid potential damage to the coil.

WARNING

Hazardous chemicals!

Coil cleaning agents can be either acidic or highly alkaline. Handle chemicals carefully. Proper handling should include 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 the refrigerant coil, use a soft brush and sprayer, such as a garden pump up or high pressure type . In addition, use a quality detergent; like “SPREX AC’, “ OAKITE 161” or “OAKITE 166” and “COILOX.”

Note: If detergent is strongly alkaline (i.e. has a pH value greater that 8.5 ) after mixing, an aluminum corrosion inhibitor must be added.

Coil Cleaning Procedure

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.

1.Disconnect power to the unit.

2.Remove panels from the unit to gain access to the coil.

3.Use a soft brush to remove loose dirt

and debris form both sides of the coil.

4.Straighten coil fins with fin comb as required.

5.Mix the detergent with water according to the manufacturers instructions.

Observe all recommendations of the cleanser manufacturer.The coil cleanser manufacturer’s recommendations, warnings and cautions will at all times take precedence to these instructions.

1.Place solution in the sprayer. Be sure to follow these guidelines if using a high-

pressure sprayer:

a)Minimum nozzle spray angle is 15°.

b)Spray solution at a 90° angle to the coil face.

c)Keep sprayer nozzle at least six inches form the coil.

d)Sprayer pressure must not exceed 600 psi.

2.Spray leaving air side of the coil first then spray the entering air side of the coil. Allow the detergent and water solution to stand on the coil for five minutes.

3.Rinse both sides of the coil with cool, clean water.

4.Inspect the coil. If it still appears dirty, repeat the cleaning procedure.

5.Reinstall all unit components and panels, and restore electrical power and gas supply to the unit.
