Friedrich 9 Routine Maintenance, Sleeve / Drain, Front Cover, Condensate Disposal System

ROUTINE MAINTENANCE (Continued)

NOTICE

Do not drill holes in the bottom of the drain pan or the underside of the unit. Not following this notice could result in damage to the unit or condensate water leaking inappropriately which could cause water damage to surrounding property.

SLEEVE / DRAIN

Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.

FRONT COVER

Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow it to dry thoroughly before reinstalling it in the chassis.

CONDENSATE DISPOSAL SYSTEM

Part 1: The system’s first stage increases energy efficiency utilizing a factory installed fan that slings the cold condensate onto the hot outdoor coil.

Part 2: When high outdoor humidity prevents slinger from disposing of all the condensate, the excess condensate overflows into the condensate drain pan and out of the 3/4” internal drain connections.

NOTICE

If Parts 1 and 2 fail for any reason, excess condensate overflows from a spillway directly into the wall plenum to the outside of the building. IF THIS OCCURS, THIS IS

A WARNING THAT THE CHASSIS OR DRAIN NEED

SERVICING.
