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

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 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-

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 handling practices. Failure to fol- low all safety instructions could result in death or serious injury.

It should be noted that the water qual- ity should be checked periodically. See Table 9.

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
