Nilfisk-Advance Select Spray 1500E Operator's Manual

INSTALLATION & PREPARATION
WATER SUPPLY:
1.
Select a water supply hose which is a quality grade of garden hose
measuring at least 3/4" ID and no longer than 50 feet.
2
Check the water inlet strainer (14) to ensure it is clean and free of any
obstructions. Periodic cleaning of the water strainer will help prevent pump
problems. As a strainer becomes obstructed, it restricts proper flow of
water to the pump. This can result in cavitations which will cause premature
failure of pump packings and valves. Using a screw driver, remove the
screen, clean or replace with Nilfisk-Advance #56632999 if necessary.
3.
Connect the hoses:
a.
Connect one end of the water supply hose to the water inlet (15) of the
unit.
b.
Connect the other end of the hose to your pressurized water supply.
c.
Connect the high pressure discharge hose (23) to the water outlet (20)
of the unit.
4.
Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 pounds per square
inch (PSI) and a maximum of 125 PSI. (A typical outdoor faucet
will generally supply this PSI if turned completely "ON")
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the pressure washer nameplate. (You
can check GPM by timing how long it takes to fill a 5 gallon
container)
c. Incoming water temperature must not exceed 190°F/ 88°C. Excessive
pump damage may result if the water temperature exceeds this
acceptable level.
5.
Never allow the unit to operate without the incoming water line attached and
the water supply turned all the way on.
