Preventive Maintenance
Water Coil Maintenance
1. Keep all air out of the water. An open loop system
should be checked to ensure that the well head is not
allowing air to infiltrate the water line. Lines should
always be airtight.
2. Keep the system under pressure at all times. It is
recommended in open loop systems that the water
control valve be placed in the discharge line to prevent
loss of pressure during off cycles. Closed loop systems
must have positive static pressure.
NOTE: On open loop systems, if the installation is in
an area with a known high mineral content (125 PPM
or greater) in the water, it is best to establish with the
owner a periodic maintenance schedule so the coil can
be checked regularly. Should periodic coil cleaning be
necessary, use standard coil cleaning procedures which
are compatible with either the cupronickel or copper
water lines. Generally, the more water flowing through the
unit the less chance for scaling.
