Please record any maintenance or service performed on this equipment in the documentation section
located at the end of this manual.
WARNING: DO NOT ATTEMPT MAINTENANCE ON THIS CONTROL UNTIL THE ELECTRICAL

General Maintenance
1. Control enclosure should be kept clean and free from any grease or dirt build-up.
2. All fasteners should be checked for tightness each time maintenance checks are preformed prior
to restarting unit.
3. Control enclosure door panel should be securely closed after maintenance to prevent tampering
or electrical shock.
4. Real Time Clock (RTC) battery should be replaced every 10 Years. Use CR2032 or equivalent.
Every Month
1. Temperature sensor(s) in exhaust hood riser(s) need to be cleaned by wiping any grease or
dust build-up from probe with a clean cloth. A clean sensor ensures that the temperature switch
will quickly respond to changes in exhaust air temperature.
2. Check all fasteners, sensors, and electrical connections for proper tightness and continuity.
Enclosure Fan Filter Inspection (Wall Mounted Enclosures Only).
1. Remove outer black plastic housing of the enclosure fan to gain access to the fan filter. The cover
is held in place by frictional clips, simply pry on it to remove.
2. Inspect the fan filter for grease/debris. If the filter is dirty, clean or replace.
Replacement fan filter part number: MC32658 (pack of 5)
WARNING: If fan filter cleaning is not performed, grease/debris buildup may occur
resulting in VFD failure due to overheating. VFD warranty may be denied if filter
inspection is not performed on a monthly basis and logged on the maintenance record.
