Failure to maintain heat exchanger coil may result in a system explosion which may cause serious injury or death.
Heat Exchanger Coil
Hard water conditions may eventually cause clogging in the heat exchanger coil if left unattended. Scale deposits will compromise the heating efficiency and produce an unsafe condition over time. It may be necessary to descale coil.
Scale buildup from certain detergents may eventually clog up the heat exchanger coil causing an unsafe condition. Use recommended detergents for better cleaning efficiency.
Black carbon deposits that collect on the outside wall of the heat exchanger coil may be a result of using a poor grade of fuel or improper burner operation. Heating fuel should be void of water and sediments to eliminate the possibility of sooting and compromising the efficiency of the coil.
Coil Descaling
We recommend that you call your local distributor to have the unit descaled.
Storage and Winterizing
Storage: Protect machine from freezing temperatures by storing in heated area.
Winterizing the float tank machines: Pour antifreeze into float tank and remove water nozzle from end of wand and carefully insert wand into opening of float tank. Start machine and run until anti-freeze water mixture has circulated throughout the machine returning back to the float tank.
Direct Drive Machines: To protect the machine from freezing temperatures while storing or transporting, connect short length of garden hose (approximately 3ft.) to water inlet connection on machine. Remove the pressure nozzle from the wand and insert the short garden hose end into a container of antifreeze. Place the wand into the antifreeze container and start engine running machine until antifreeze appears from the end of the wand. Turn engine "OFF" and replace pressure nozzle. Coil up hose and move machine to storage area.
