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 flowing through the unit
the less chance for scaling.
Water Coil Maintenance –
(All 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 flowing
through the unit, the less chance for scaling, however
excessive flow rates can produce water (or debris)
velocities that can erode the heat exchanger wall and
ultimately produce leaks.
Compressor
Conduct annual amperage checks to ensure amp draw
is no more than 10% greater than that indicated by serial
plate data.
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 equipment cabinets are set up
from the floor 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 water flow rates are at proper
levels before servicing the refrigerant circuit.
