Cleaning 

 

For best possible performance and a long life, the 
AHU should be kept clean.  Please see instructions 
below on how to clean fans and heat exchanger. 

 

Changing filters 

 

There are two filters in this AHU:  exhaust air filter 
and supply air filter (fresh air). 
Both filters should be changed at least once a year, 
and more often if need be. Do not wash the filters, 
but exchange them for new ones. 
To buy new filters, please contact the local dealer in 
your country

 

or order from 

www.rec-indovent.se

 

 
 
           NOTE!  The Temovex AHU must be fitted 
with the Temovex filters listed on page 1 of this 
manual.  If the unit operates without filters, the 
performance will be affected adversely and fans and 
heat exchanger may be seriously damaged.

The unit operates even if the filters are dirty, but the 
performance would be less good;  energy 
consumption increases and heat recovery 
decreases.
