SERVICE

Perform the procedures outlined below periodically, as
indicated.
IMPORTANT: When a compressor is removed from this
unit, system refrigerant circuit oil will remain in the com-
pressor. To avoid leakage of compressor oil, the refrigerant
lines of the compressor must be sealed after it is removed.
IMPORTANT: All refrigerant discharged from this unit
must be recovered without exception. Technicians must fol-
low industry accepted guidelines and all local, state and fed-
eral statutes for the recovery and disposal of refrigerants.
IMPORTANT: To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must only be
serviced by technicians who meet local, state and federal
proficiency requirements.
IMPORTANT: To prevent injury or death due to electrical
shock or contact with moving parts, open unit disconnect
switch before servicing unit.
Filters must be clean for maximum performance.
Filters —
Inspect filters every month under normal operating conditions.
Replace when necessary.
IMPORTANT: Units should never be operated with-
out a filter.
Keep all air out of the water coil. Check
Water Coil —
open loop systems to be sure the well head is not allowing air
to infiltrate the water line. Always keep lines airtight.
Inspect heat exchangers regularly, and clean more frequent-
ly if the unit is located in a "dirty" environment. Keep the heat
exchanger full of water at all times. Open-loop systems should
have an inverted P trap placed in the discharge line to keep
water in the heat exchanger during off cycles. Closed-loop
systems must have a minimum of 15 psig during the summer

NOTES:
1. If there is no fault in memory, the Fault LED will flash code 1.
2. Codes will be displayed with a 10-second Fault LED pause.
3. Slow flash is 1 flash every 2 seconds.
4. Fast flash is 2 flashes every 1 second.
5. EXAMPLE: "Flashing Code 2" is represented by 2 fast flashes followed by a
10-second pause. This sequence will repeat continually until the fault is
cleared.
and 40 psig during the winter. Generally, the higher the water
flow through the bail, the lower the chance for sealing.
Check P trap frequently for proper operation.
IMPORTANT: To avoid fouled machinery and extensive
unit clean-up, DO NOT operate units without filters in
place. DO NOT use equipment as a temporary heat source
during construction.
Condensate Drain Pans —
pans for algae growth twice a year. If algae growth is apparent,
consult a water treatment specialist for proper chemical treat-
ment. Applying an algaecide every three months will typically
eliminate algae problems in most locations.
Refrigerant System —
are at proper levels before servicing. To maintain sealed circuit-
ry integrity, do not install service gauges unless unit operation
appears abnormal.
Check to see that unit is within the superheat and subcool-
ing temperature ranges shown in Tables 16-22. If the unit is not
within these ranges, recover and reweigh in refrigerant charge.
Conduct annual amperage checks to en-
Compressor —
sure that amp draw is no more than 10% greater than indicated
on the serial plate data.
All units have lubricated fan motors. Fan
Fan Motors —
motors should never be lubricated unless obvious, dry opera-
tion is suspected. Periodic maintenance oiling is NOT recom-
mended as it will result in dirt accumulating in the excess oil
and cause eventual motor failure. Conduct annual dry opera-
tion check and amperage check to ensure amp draw is no more
than 10% greater than indicated on serial plate data.
Condensate Drain Cleaning —
and unit drain pan at the start of each cooling season. Check
flow by pouring water into drain. Be sure trap is filled to main-
tain an air seal.
Air Coil Cleaning —
orator coil as required by condition of the coil. A 10% solution
