WARNING! TURN OFF CASE BEFORE PERFORMING PREVENTIVE MAINTENANCE!
Condensate Package (Including Overflow Condensate Pan):
Caution! You must turn main power switch off before cleaning!
• Remove front (or rear) grille (by removing thumbscrews or disconnecting from magnets).
• Carefully slide out refrigeration assembly (taking care to not damage coil)!
• Remove wicking material (if any).
• Use vacuum (in suction mode) and brush to dislodge and remove dust both in and on coil fins.
• To remove dust/debris from inner fins, place damp rags around condensing fan motor brackets (to
collect airborne dust). Then, switch vacuum to blow mode to blow air through condenser coils and into
damp rags on fans. Blow entire surface of condensing coil to assure that all entrenched dust is
removed. Caution! Coil fins are sharp!
• Use a scrub-brush and a non-corrosive de-scaling solution (to remove calcium, lime and rust) from
condensate pan. Clean hot gas loop (for EnergyWise units) or electric coil (for standard units). Follow
instructions as to proper dilution, safety precautions and scrubbing method.
• After thoroughly cleaning pan with scrub-brush and solution, rinse component with clean water and
wipe dry with sponge or paper towel.
• Use mild all-purpose cleaner and soft cloth to clean fans, sight glass, overflow pan, etc.
• Return wicking material to mounting brackets. If wicking material is tattered, torn or disintegrating,
replace with new. If wicking material is not available, contact Structural Concepts. See toll-free
number at last page of operating manual.
• Slide condenser package back under case.
• Return front (or rear) grille to case.
• Turn power back on to case.
