NOTICE:
The unit is fitted with sensitive electronic
sensors. Protect the sensors from impact and do not
expose them to water or cleaning solution.
Vacuum or use compressed air on both sides of the
upright (condenser) coil until it is clean. Take care not to
let the nozzle touch the fins; as this may damage the
fins.

only. Follow instructions on product label. Take care not
to spray or wipe Coil Cleaner on or near any electrical
components or sensors. To clean the vertical

orientation. When installing the rear cover, carefully
thread the pump hose through the hole in the back
pocket before putting the cover in place.
NOTICE:

edges of the evaporator and condenser coils to
provide an airtight seal around the heat exchange
