PORTABLE WATER SUPPLY (DE-4)
The optional DE-4 water tank allows the 2000 Plus Scaler Motor Pack Combo to
be used anywhere that 120V 60Hz electrical power is available.
The DE-4 tank is fitted with a hose terminated by the same quick release coupler
normally shipped with the 2000 Plus allowing very rapid change over from fixed
to portable use without tools.
It is imperative for antiseptic reasons to fill the DE-4 tank only with clean,
drinkable, cold water. See page 1. Distilled water is desirable because it has the
additional advantage of being mineral free.
Anti-microbial agents per se added into the water do not harm the DE-4 tank or the 2000 Plus
water system. However, over time and with continual use, deposits will form in the tubing and in
the water system. Depending on concentration, deposits in the 2000 Plus water system could
eventually become severe enough to restrict water flow to the point where the unit will have to
be returned to Delmarva 2000
TM
for service. The same is true for hard water.
USING THE DE-4
Remove the top of the DE-4 by turning counter-clockwise. Each day fill
with clean, drinkable, COLD water. Do not use hot water. Replace the
top by turning clockwise. Using the handle, pump up the pressure until
the yellow ring is visible. Connect the water line from the 2000
Plus
unit via the quick disconnect. See page 6 for purging the system. NOTE:
Under typical conditions, it is expected that the water in the DE-4 will
eventually reach room temperature. This is normal and the 2000 Plus
should operate as intended.
At the end of each day’s use, release pressure from the tank by pulling out the button on the side
of the DE-4 tank. Uncouple the quick disconnect. Note that the button may be rotated ¼ turn
counterclockwise and will stay open until turned back clockwise.
To insure cleanliness of the DE-4, it is advisable to periodically rinse it out with a suitable anti-
microbial solution. Be sure to drain and rinse thoroughly before use with the 2000 Plus unit.
Drain and refill regularly. Do not allow water to become stale. Be sure to drain the DE-4
completely if storing or transporting in freezing conditions.
