CAUTION: Microbial Growth! Wet interior unit insulation can become an amplification site for microbial growth (mold), which may cause odors and damage to the equipment and building materials. If there is evidence of microbial growth on the interior insulation, the insulation should be removed and replaced prior to operating the system.

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. Handle chemical 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.

Inspect coils for dirt build-up

Disconnect all electrical power to the unit

Use a soft brush to remove loose debris from both sides of the coil

Install a block-off to prevent spray from going through the coil and into a dry section of the unit and/or system ductwork

Mix a high-quality coil cleaning detergent with water according to the manufacturer’s instructions

Place the mixed solution in a garden pump-up sprayer or high-pressure sprayer

Maintain minimum nozzle spray angle of 15 degrees
