The circulating pump installed in the appliance has the following features:
ATTENTION: FOR THE DELIVERY, RETURN, MAKE-UP AND DISCHARGE CONNECTIONS USE FLEXIBLE TUBES
HAVING A LENGTH OF AT LEAST 70 CM TO FACILITATE MOVING THE APPLIANCE FOR MAINTENANCE.
ATTENTION: A CONNECTION MUST BE MADE BETWEEN THE SAFETY VALVE AND THE OUTLET TO PREVENT
DAMAGING MATERIALS SURROUNDING THE APPLIANCE WHEN THE VALVE IS ACTIVATED.
ATTENTION: To avoid continual startups and shut offs, the size of the plant must be such as to guarantee power
absorption that is not less than the power generated by the generator running at minimum steady state power level.
