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.

cleaned every 3months.Use a vacuumcleaner to remove the  
heaviest portion of accumulated dust, then wash in warm
