Unit Maintenance – Filters
Q-TEC Indoor Products – Filters and Filter Servicing
The Q-TEC indoor air conditioners and heat pumps have two room air filters that must be replaced when servicing
the unit. Filters play an important part in proper unit operation and prevent dirt and dust buildup inside the Q-TEC
and the room the unit is installed in. To access the unit filters, open the front hinged door by unlocking the door
latch. The door folds outward and is on hinges with lift-off pins. Use care when opening doors. If the door is lifted off
of the hinge pins, use care as the insulation and louver grille cause the door to be heavy.
The upper section of the Q-TEC contains two 1" throwaway filters standard with every unit. These filters filter the air
used for cooling inside the classroom or structure and should be changed regularly.
The Q-TEC product installation instructions contain additional information regarding unit maintenance. This
information may be accessed at

Pre-filter location
The Q-TEC will have a permanent pre-filter installed inside
the wall sleeve if air intake vent options are inside the unit.
The pre-filter must be inspected and cleaned when necessary.
The easiest way to remove the pre-filter is through the outdoor
louver. Clean the pre-filter with soapy water.
