Maintenance
Fluid coolers require a minimum of maintenance. Electrical connections should be checked
on an annual basis. Fan contactors should be inspected and replaced when there is evidence
of pitting or burning. Verify controls settings and operation at least on an annual basis.
Condenser fan motors have sealed ball bearings that do not require service. Replace
bearings when necessary.
The cooling fluid should be checked on a regular basis for proper inhibitors and glycol mix.
The unit coil will require periodic cleaning based on operation and atmosphere conditions.
Clean the unit using a brush or commercially available coil cleaners and water. Take care
not to deform the fin material. Straighten any bent fins using a fin tool.
Cleaning Instructions
CAUTION
!
Never clean this unit with an acid based cleaner.
Clean the finned surface at least every six months; more frequent cleaning may be required
if extreme conditions cause clogging or fouling of air passages through the finned surface.
Use Calgon Corporation's CalClean 41352 (or equal). Apply CalClean liberally to entering
air and leaving air surfaces of the finned area according to label directions and rinse
thoroughly to remove all cleaners.
