Gemini® Select Air-Cooled Condenser 09DP: Microchannel Heat Exchanger (MCHX) Condenser Coil Maintenance and Cleaning Recommendations

! CAUTION

Do not apply any chemical cleaners to MCHX condenser coils. These cleaners can accelerate corrosion and damage the coil.

Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit.

The following steps should be taken to clean MCHX condenser coils:

Remove any foreign objects or debris attached to the core face or trapped within the mounting frame and brackets.
Put on personal protective equipment including safety glasses and/or face shield, waterproof clothing and gloves. It is recommended to use full coverage clothing.
Start high pressure water sprayer and purge any soap or industrial cleaners from sprayer before cleaning condenser coils. Only clean, potable water is authorized for cleaning condenser coils
Clean condenser face by spraying the core steady and uniformly from top to bottom while directing the spray straight toward the core. Do not exceed 900 psig or 30 degree angle. The nozzle must be at least 12 in. from the core face. Reduce pressure and use caution to prevent damage to air centers.

! CAUTION

Excessive water pressure will fracture the braze between air centers and refrigerant tubes.
