PREVENTIVE MAINTENANCE

Water Coil Maintenance –

(Direct Ground Water Applications Only)

If the installation is performed in an area with a known

high mineral content (125 P.P.M. or greater) in the

water, it is best to establish with the owner a periodic

maintenance schedule so the coil can be checked

regularly. Consult the well water applications section

of this manual for a more detailed water coil material

selection. Should periodic coil cleaning be necessary, use

standard coil cleaning procedures which are compatible

with either the heat exchanger material or copper water

lines. Generally, the more water ﬂ owing through the unit

the less chance for scaling therefore 1.5 gpm per ton is

recommended as a minimum ﬂ ow.

Water Coil Maintenance –

(Other Water Loop Applications)

Generally water coil maintenance is not needed however,

if the installation is located in a system with a known

high dirt or debris content, it is best to establish with

the owner a periodic maintenance schedule so the coil

can be checked regularly. These dirty installations are a

result of the deterioration of iron or galvanized piping

or components in the system or open cooling towers

requiring heavy chemical treatment and mineral buildup

through water use. Should periodic coil cleaning be

necessary, use standard coil cleaning procedures which

are compatible with both the heat exchanger material and

copper water lines. Generally, the more water ﬂ owing

through the unit, the less chance for scaling, however ﬂ ow

rates over 3 gpm per ton can produce water (or debris)

velocities that can erode the heat exchanger wall and

ultimately produce leaks.

Filters – Filters must be clean to obtain maximum

performance. They should be inspected every month

under normal operating conditions and be replaced when

necessary. Units should never be operated without a ﬁ lter.

Washable high efﬁ ciency electrostatic ﬁ lters, when dirty,

can exhibit a very high pressure drop for the fan motor

and reduce air ﬂ ow resulting in poor performance. With

ICM2 fan motors, excessive fan watts will be used as

well. It is especially important to provide consistent

washing of these ﬁ lters (in opposite direction of the

normal air ﬂ ow) once per month using a high pressure

wash similar to that found at self-serve car washes.

Condensate Drain – In areas where airborne bacteria

produce a slime in the drain pan, it may be necessary to

treat chemically with an algaecide every three months

or so to minimize the problem. The condensate pan may

also need to be cleaned periodically to assure indoor air

quality. The condensate drain can pick up lint and dirt,

especially with dirty ﬁ lters. Inspect the drain twice a year

to avoid the possibility of overﬂ ow.

Fan Motors - All units have lubricated fan motors.

FAN MOTORS SHOULD NEVER BE LUBRICATED

UNLESS OBVIOUS, DRY OPERATION IS

SUSPECTED. Periodic maintenance oiling is not

recommended because it will result in dirt accumulating

on excess oil and cause eventual motor failure.

Air Coil – The air coil must be cleaned to obtain

maximum performance. Check once a year under normal

operating conditions and, if dirty, brush or vacuum clean.

Care must be taken not to damage the aluminum ﬁ ns

while cleaning. CAUTION: Fin edges are sharp.

Hot Water Generator Coils – See water coil maintenance

for ground water units. If the domestic water is hard or

not chemically softened the high temperatures of the

desuperheater will tend to "lime up" even quicker than the

water coil and may need more frequent inspections.

Cabinet - Do not allow water to stay in contact with the

cabinet for long periods of time to prevent corrosion of

the cabinet sheet metal. Generally the cabinet is set up

from the ﬂ oor a few inches for prevention. The cabinet

can be cleaned using a mild detergent.

Refrigerant System - To maintain sealed circuit integrity,

do not install service gauges unless unit operation appears

abnormal. Reference the operating chart for pressure and

temperatures. Verify that air and water ﬂ ow rates are at

proper levels before servicing the refrigerant circuit.
