Preventative Maintenance
Water Coil Maintenance for attached forced
air heating systems:
(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.
If periodic coil cleaning is necessary, use
standard coil cleaning procedures that 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 therefore 1.5gpm
per ton is recommended as a minimum flow.
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
all cabinets are set up from the floor a few inches
on an isolation pad for sound control. 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 flow rates are at proper levels before
servicing the refrigerant circuit.
Water Coil Maintenance for attached forced
air heating systems:
(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. If periodic
coil cleaning be necessary, use standard coil
cleaning procedures which are compatible with
both the heat exchanger material and copper
water lines. Generally, more water flowing
through the unit lowers the chance for scaling.
However, flow rates over 3gpm per ton can
produce water (or debris) velocities that can
erode the heat exchanger wall and ultimately
produce leaks.
