Inspect And Cleaning The Lndoorair Coil; Inspect The Outdoorair Intake And Exhaust; Inspect And Clean The Condensate Drain - Friedrich Vert-I-Pack B Series Installation & Operation Manual

INSPECT AND CLEAN INDOOR-AIR COIL
Eventually, minor amounts of lint and dirt may pass through the filter and collect on the indoor-air coil. These minor
accumulations can be carefully vacuumed away with a brush attach ment on a vacuum cleaner. Care must be taken to avoid
bending the aluminum fins on the coil. Bent fins should be straightened using a special fin tool available from most HVAC
service technicians.
INSPECT OUTDOOR-AIR INTAKE AND EXHAUST
The unit's outdoor-air intake and outdoor-air exhaust paths must remain clear. Check the OA exhaust frequently. Keep it
free of all debris, snow, or ice. The OA intake should also be kept free of obstructions. Blocking the OA exhaust or OA inta ke
opening will reduce the efficiency of your unit, could damage it, and void your warranty.
INSPECT AND CLEAN CONDENSATE DRAIN
The condensate drain must be routed to a suitable drainage area. Check the unit condensate drain periodically. Keep it free
of anything that may block or impede the flow of condensate water. If there is any accumulation of foreign matter in the drain
pipe, it should be removed and cleaned. The entire drain line must be protected from freezing.
