Carrier Chillers 30RB

Check condenser coils for debris; clean as necessary with Carrier approved coil cleaner.

Check moisture indicating sight glass for possible refrigerant loss and presence of moisture.

Check all refrigerant joints and valves for refrigerant leaks; repair as necessary.

Check chilled water flow switch operation.

Check all condenser fans for proper operation.

Check oil filter pressure drop.

Check oil separator heater operation.

Inspect pump seal if unit has a hydronic pump package.

General Cleaning and Tightening Connections

General connections cleaned and tightened?

Change Oil Filter (Screw Compressors) (Initially Year 1 then As Needed)

Cooler: Inspect and Clean Cooler Tubes (Every 3 - 5 Years)

Cooler tubes inspected and cleaned?

Eddy Current Test (Every 3 - 5 Years)

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

Removal of any foreign objects or debris attached to the coil face or trapped within the mounting frame and brackets.

Proper personal protective equipment worn, including safety glasses and/or face shield, waterproof clothing and gloves. Full coverage clothing is recommended.

High pressure water sprayer started and any soap or industrial cleaners purged from sprayer before cleaning condenser coils. Only clean potable water is authorized for cleaning condenser coils.

Condenser face cleaned by spraying the coil steady and uniformly from top to bottom while directing the spray straight toward the coil. Pressure did not exceed 900 psig (6205 kPa) or 30 degree angle. The nozzle was at least 12 in. (304.8 mm) from the coil face. Pressure was reduced and caution used to prevent damage to air centers.

Sign off on the MCHX Condenser Coil Maintenance

Check all electrical connections; tighten as necessary.

Inspect all contactors and relays; replace as necessary.

Check accuracy of thermistors; replace if greater than ±2°F (1.2°C) variance from calibrated thermometer.

Check accuracy of transducers; replace if greater than ±5 psi (34.47 kPa) variance.

Check to be sure that the proper concentration of antifreeze is present in the chilled water loop, if applicable.

Verify that the chilled water loop is properly treated.

Check refrigerant filter driers for excessive pressure drop; replace as necessary.

Check chilled water strainers, clean as necessary.

RTPF Condenser Coil Maintenance and Cleaning Recommendations

Note: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil. This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to using low velocity clean water rinse.

Routine Cleaning for RTPF Coil Surface

Caution: Harsh chemicals, household bleach or acid or basic cleaners should not be used to clean outdoor or indoor coils of any kind.

Caution: High velocity water from a pressure washer, garden hose, or compressed air should never be used to clean a coil.

Totaline Environmentally Sound Coil Cleaner Application Instructions

Proper eye protection such as safety glasses is used during mixing and application.
