FloAire DX COIL - Manual (Page 7)

EVAPORATOR IOM
Operation
1. Proper air distribution is vital to coil performance. Air flow anywhere on the coil face
should not vary by more than 20%.
2. Air velocities should be maintained between 200 and 550 feet per minute.
3. The drain pan should be designed and installed such that there is no standing water.
Maintenance
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 for leaks is recommended.
Small leaks can be detected using a Halide torch. Repair and replacement of the coil and
the connecting piping, valves, etc., should be performed 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. The use of filter-dryers in the system piping is recommended along with a sight glass that
has a moisture indicator. Replace the filter dryer(s) as needed.
Note: Refrigerant conversions are beyond the scope of this manual and should only be performed by
qualified parties.
