Maintenance
Preventive Maintenance
Maintenance on the unit is simplified with the following
preventive suggestions:
Filter maintenance must be performed to assure proper
operation of the equipment. Filters should be inspected at
least every three months, and replaced when it is evident
they are dirty. Filter sizing is shown in
Table 57, p. 101
:
Check the contactors and relays within the control panel at
least once a year. It is good practice to check the tightness
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 system.
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 experienced
service person.
It should be noted that the water quality should be checked
periodically. See
Table 58, p. 101
.
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 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 Service Procedures!
The maintenance and trouble shooting procedures
recommended in this section of the manual could result
in exposure to electrical, mechanical or other potential
safety hazards. Always refer to the safety warnings
provided throughout this manual concerning these
procedures. When possible, disconnect all electrical
power including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized. When
necessary to work with live electrical components, have
a qualified licensed electrician or other individual who
has been trained in handling live electrical components
per these tasks. Failure to follow all of the
recommended safety warnings provided, could result in
death or serious injury.

WARNING
Hazardous Chemicals!
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 manufacturers
Materials Safety Data Sheet and follow all
recommended safe handling practices. Failure to follow
all safety instructions could result in death or serious
injury.
