handling parts or reaching into the unit. Wear appropriate
protective clothing and gloves when working on this unit.

breakers are ON or that fuses have not blown. If you must reset
breakers or replace fuses, do so only once. Contact your servicing
dealer for assistance if the breakers trip or the fuses blow a second
time.
PERFORMING ROUTINE MAINTENANCE
1. The motors are factory lubricated. Lubricating the bearings
is not recommended.
2. The heat recovery coremust be handled with care. To ensure
maximum efficiency of the plastic partitions wash core once
a year following the season of most intense use.
S Check for sufficient airflow. Check air filters for accumulations of
large particles. Check for blocked exhaust--air grilles or ductwork.
Keep grilles and duct work open and unobstructed.
S If the condensate fails to drain properly, check the grommet and
drain tube for obstructions. Make sure that the condensate drain
tube has a slight slope and is not kinked.
Allowthe heat recovery core to soak for 3 hours in a
solution ofwarmwater and mild soap. Rinse under a stream
ofwarm water. Hot water and strong detergent should NOT
be used,as it will damage the heat recovery core.
