Unit Maintenance – Filters
I-TEC Indoor Products – Filters and Filter Servicing
The I-TEC indoor air conditioners and heat pumps have multiple lters that must be maintained and inspected when
servicing the unit. Filters play an important part in proper unit operation and prevent dirt and dust buildup inside the
I-TEC and the room the unit is installed in. To access the unit lters, open the front hinged doors by unlocking the
door latches. The doors fold outward and are on hinges with lift-off pins. Use care when opening doors. If doors are
lifted off of the hinge pins, use care as the dense insulation used for sound reduction causes the doors to be heavy.
The upper section of the unit contains two 2" x 24" x 30" throwaway lters as standard with every unit. MERV ratings
of the lter are available up to MERV13. These lters lter the air used for cooling inside the classroom or structure
and should be changed regularly.
If the unit has an air intake vent option installed, two 1" x 12" x 20" lters are located in the lower section of the
front doors behind the louvers. These lters help keep the vent option clean and operating properly.
Two washable lters are also installed in the air intake vent option. These should be inspected during servicing and
cleaned when necessary. The washable lters are used to remove dirt and dust from outdoor air that is entering the
vent area. If at any time these lters are damaged, they must be replaced with Bard-approved lters.
I-TEC Filter Locations:
Servicing the filters in your unit will help keep
the inside of the unit clean and also the area it is
installed in.
