Maintenance
General
1. Filters should be inspected on a regular basis and changed as needed. Maintaining clean
filters is a cost effective way to help maintain maximum coil performance and service life.
2. Periodic inspection of the coil for signs of corrosion and/or leaks is recommended. Re-
pair and replacement of the coil and the connecting piping, valves, etc., should be per-
formed as needed by a qualified individual(s).
3. Should the coil surface need cleaning, caution should be exercised in selecting the clean-
ing solution as well as the cleaning equipment. Improper selection can result in damage
to the coil and/or health hazards. Clean the coil from the leaving air-side so that foreign
material will be washed out of the coil rather than pushed further in. Be sure to carefully
read and follow the manufacturer’s recommendations before using any cleaning fluid.
4. Maintain the circulated fluid free of sediment, corrosive products and biological con-
taminants. Periodic testing of the fluid followed by any necessary corrective measures
along with maintaining adequate fluid velocities and proper filtering of the fluid will help
to satisfy this goal.
5. If automatic air vents are not utilized, periodic venting of the coil is recommended to
remove accumulated air. Caution should be exercised to avoid injury. High pressure
and/or high temperature fluids can cause serious personal injury.
6. Heatcraft’s cleanable coils with removable box headers should be cleaned using a suit-
able brush or its equivalent. Dislodged debris should be flushed from the coil and drain
pan. Be sure that debris does not clog the drain. After the coil has been cleaned, the old
gaskets should be discarded and replaced with new ones (contact your local Heatcraft
representative for replacement gaskets). The box header should then be reinstalled. The
recommended installation procedure is as follows.

General
1. Proper air distribution is vital to coil performance. Air flow anywhere on the coil face
should not vary by more than 20%.
2. The drain pan and associated piping (drain line and trap) should be installed so that there
is no standing water in the drain pan and that no blow-through occurs.
3. Fluid and air velocities should be maintained within Heatcraft’s recommended values.
