Water System Freeze Protection
Ensure that freeze protection is provided for the outdoor portion of the water loop system. Inadequate
freeze protection can lead to coil damage.
NOTE: A potential situation may occur during construction where the system fluid loop is drained after
being cleaned, flushed and tested. KlassKeeper unit will not completely drain and may hold fluid in the
condenser or the heating coil. Extensive damage may result to internal components if the system fluid
freezes – an adequate glycol concentration must be added if a possibility of freezing exists.
Remove Air from System fluid Loop
Air in the system impairs unit operation and can cause erosion in the system piping.
Air Balancing
Air balancing of the system should be performed while the unit’s fan is operating at high-speed. In order
to ensure the fan is operating at high-speed, the unit must be placed into cool mode.
Clean Unit Filters
Check to ensure the unit filters are clean: each KlassKeeper unit is equipped with three filters – a pleated
supply air filter and a wire-frame fresh and return air filters. This contributes to the proper operation of
the unit by ensuring adequate air flow across the coil. For wire-frame filter only, a vacuum may be used
to remove any debris or dirt.
SAFETY NOTE: In the following part of the procedure it will be necessary to access the areas around the
electrical wiring and the circuit board. Do not adjust or remove any board connections or wiring
connections to other components without first powering down the unit. Disconnects are usually within
reach of the unit. Exercise caution at all times.
Fan Rotation:
Inspect all fans (circulating, outside air supply and exhaust air fans) in the unit to ensure they are clean of
any debris and rotate freely.
NOTE: This equipment is designed for indoor installation ONLY.
Start-up:
To register the unit warranty proper start-up is required by a factory approved technician. The following
items must be recorded and returned to the factory to register the warranty. The factory reserves the
right to refuse warranty if these details are not provided.
