Maintenance

Preventive Maintenance

Maintenance on the unit is simplified with the following preventive sugges- tions:

Filter maintenance must be performed to assure proper operation of the equipment. Filters should be inspect- ed at least every three months, and re- placed when it is evident they are dirty. Filter sizing includes:

disconnect power before servic- ing could result in death or seri- ous injury.

Check the contactors and relays within the control panel at least once a year. It is good practice to check the tight- ness of the various wiring connections within the control panel.

A strainer (60 mesh or greater) must be used on an open loop system to keep debris from entering the unit heat exchanger and to ensure a clean sys- tem.

For units on well water, it is important to check the cleanliness of the water- to-refrigerant heat exchanger. Should it become contaminated with dirt and scaling as a result of bad water, the heat exchanger will have to be back flushed and cleaned with a chemical that will remove the scale. This service should be performed by an experi- enced service person.

Condensate Trap

For units incorporating a negative trap design, ensure that the condensate system is primed with water at all times. Allowing a negative, pressure condensate system to run dry could cause a break in the condensate seal

Hazardous

Chemicals!

Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper han- dling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as re- quired. For personal safety, refer to the cleaning agent manufactur- ers Materials Safety Data Sheet and follow all recommended safe

allowing the fan to draw water from the condensate line to spray moisture into the mechanical system. By maintaining a primed condensate trap, a seal will be created and will help prevent these complications.

WARNING

Hazardous

Voltage!

Disconnect all electric power, in- cluding remote disconnects be- fore servicing. Follow proper lockout/tagout procedures to en- sure the power can not be inad- vertently energized. Failure to
