Why a SOP
A fouled core loses effectiveness and raises fan energy. A written procedure keeps performance up and warranty valid.
Annual Inspection
- Record supply-air temperature and pressure drop as baseline
- Inspect the core for dust, grease, or condensate buildup
- Check rotary seals, belt, and bearings if fitted
Cleaning Steps
- Switch the unit off and lock out power
- Remove filters and vacuum loose dust from the core faces
- Wash with low-pressure water and a neutral cleaner; never use high pressure that bends foils
- For greasy exhaust, use a degreaser suited to the media
- Rinse, dry, and refit; confirm drainage is clear
Rotary Wheels
Clean the media per the manufacturer schedule, inspect seals, and verify the drive. Log every service with the date and readings.
