A dedicated maintenance program will prolong the life of
the equipment, and maintain its optimum performance.
We recommend at least two (2) full inspections and
cleanings per year under normal operating conditions, and
more if circumstances warrant it (i.e. situations of heavy
smoke may require servicing every one to two months).
Service should include:
• Cleaning of screens protecting outside hoods.
• Cleaning of the HRV (aluminum) core.
• Inspect filters and replace as necessary.
• Wipe down drain pans and inside of cabinet, using a mild
disinfectant.
• Ensure condensate drain has free flow of moisture.
• Inspect operation of blowers and electrical panel.
• Confirm operation.

c) Once removed from the cabinet, remove the foam filters.
d) Wash the core in warm soapy water (do not use dish-
washer).
