Operating Instructions
PRIMING THE PUMP
It is essential to prime the pump and flush the unit each time the water
supply has been disconnected from the unit OR whenever the unit has
set for any period of time. This unit has a steel coil which, after setting,
will cause the water remaining in the coil from the previous usage to
turn brown or black. This contaminated water must be flushed from the
system before start-up. This procedure should be performed without the
high pressure hose, gun and dual lance assembly installed.
DIRECT FEED : All units.
1. Turn on the water supply.
2. Low pressure water will begin flowing from the water outlet. This al-
lows the unit to prime and purge any air from the system. The unit is
primed when water flow is uninterrupted by air.
3. Once the unit is primed, turn off the water supply and connect the high
pressure discharge hose to the water outlet of the unit. (Note: The trig-
ger gun and dual lance assembly should already be connected to the
high pressure discharge hose at this time.)
4. Turn on the water supply.
CAUTION
BE CERTAIN THE HOSE, GUN & LANCE ASSY. ARE NOT
CONNECTED TO THE UNIT WHILE PRIMING THE PUMP. PRIMING
ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE
SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE GUN
AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.
