Clean inside the power supply

 The top and side panels

 The fans

Be careful not to damage the circuit boards.
5. Install the top and side panels before you turn ON the power.
Clean the chiller air filter
Chillers have 3 reusable air filters. Chillers in dusty environments need their filters cleaned more frequently.
Do not let the air filters become clogged with dust. This reduces air flow and can decrease cooling efficiency. It can also
lead to filter breakthrough, allowing dust to get into the condenser coils.
To remove and clean the chiller’s air filters:
1. Hold the strap at the bottom center of the filter and carefully lift it up and away from the chiller housing.
2. Use a water or high pressure air stream directed through the back of the air filter (the downstream side) to remove
dust from the filter. Let the filter dry, as required.
3. Position the top edge of filter in the upper channel of the chiller housing.
4. Carefully lift on the bottom strap while pushing the bottom edge of the filter toward the housing.
WARNING!
ELECTRIC SHOCK CAN KILL
Disconnect electric power before performing any maintenance.
All work requiring removal of the power supply cover must be performed by
a qualified technician.
Read the Safety and Compliance Manual (80669C) for important safety
information.
