Maintenance Precautions - Ramteq MVD Series Operator's Manual

MAINTENANCE PRECAUTIONS

Do not permit acidic, caustic or abrasive fluids to be pumped through system.
Periodically clean detergent inlet screen. This will ensure proper flow of water to the pump.
High mineral content in water may adversely affect your machine and may require the use of a water softener
to ensure proper operation.
NEVER run the pump dry under any circumtances. Doing so will cause extreme damage to the pump.
HEAT EXCHANGER COIL MAINTENANCE
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 only 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.
MOVING, STORAGE
Place machine in covered area when not in use to protect from elements. Protect machine from
freezing in cold temperatures by storing in a heated location.
ENGINE MAINTENANCE
Refer to Engine Manual.

WINTERIZING
n Non-float Tank Machines: To protect the machine from freezing temperatures while
storing or transporting, connect short length of garden hose (approximately 3 ft.) 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.
