Airfl Ow; Improper Outdoor Coil Airfl Ow (Recirculating Hot Exhaust Air); Proper Outdoor Coil Airfl Ow - GE Zoneline 6100 Series Technical Service Manual

Proper Outdoor Coil Airfl ow
When properly installed in the correct wall case, the rubber seals on the inside of the outdoor grille should
fi t tightly against the metal brackets on the outdoor coil. This will prevent condenser hot exhaust air from
being recirculated through the coil, and will allow fresh outdoor air to enter from each of the rear sides of
the outdoor grille. The outdoor fan motor and grille work together to provide proper airfl ow. The fan motor
draws air in through each side of the outdoor grille, and the air is then blown out through the condenser
coil, and discharged to the outside. When sliding the chassis back into the case, it is very important to slide
the chassis all the way into the case for proper airfl ow. It is also important to have the proper outdoor grille
installed on the case.

Improper Outdoor Coil Airfl ow
When improperly installed, the rubber seals on the inside of the outdoor grille do not fi t against the metal
brackets on the outdoor coil. This allows hot outdoor coil exhaust air to recirculate across the compressor
and outdoor coil. When this condition occurs, the compressor overheats and eventually cycles off on the
compressor overload protector (compressor shuts off). After the compressor cools, it restarts and the cycle
repeats itself. If this installation problem is not corrected, damage to the compressor can occur.
