DEFROSTING
Excessive frost/ice build up on the plate will reduce the cooling effect by insulating the
evaporator plate. Allowing the evaporator plate to warm above freezing is one method
of defrosting. Boiling water or a scraper will also work.
OPERATION INSPECTION
Within a few minutes of starting the Sea Frost BD, the tubing in close proximity to the
valve mounted on the plate and the valve itself will be noticeably cold. IF AFTER 20
MINUTES OF OPERATION, COOLING IN THIS AREA IS NOT OBSERVED DO NOT
CONTINUE TO OPERATE THE SYSTEM.
IMPORTANT: When using the water pump, check water flow and periodically inspect
and clean the seawater strainer.

WATER COOLED MAINTENANCE
Drain all water from the pump, sea strainer, hoses and water coil in the BD housing
when entering a freezing climate. Switch off the pump to avoid dry pump operation.
