Nozzle Connection; Water Supply - Graco 2525 Instructions Manual

INSTALLATION & PREPARATION
INSTRUCTIONS

Nozzle Connection

Be certain the trigger gun is locked in the "OFF" posi-
tion.
The nozzle assembly should be disconnected from
the gun/wand assembly at this time by retracting the
locking ring on the quick-connect fitting to remove the
nozzle.

Water Supply

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.
Check the water inlet strainer 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 cavita-
tions which will cause premature failure of pump
packings.
NOTICE
1. Using a screw driver, remove the screen from the water
inlet.
2. Clean or replace if necessary.
Connect the hoses.
1. Connect one end of the water supply hose to the water
inlet of the unit.
2. Connect the other end of the hose to your pressurized
water supply.
Note: Do not use a non-pressurized water supply (i.e.
from a pond or well) with this unit.
3. Connect the high pressure discharge hose to the water
outlet of the unit.
4. Securely connect the other end of the hose to the
gun assembly. (A wrench may be required on some
models.)
5. Connect the wand assembly to the gun/hose
assembly.
Follow the incoming water requirements listed below:
1. Water pressure must be a minimum of 25 pounds per
square inch (PSI) and a maximum of 125 PSI. (A typical
outdoor faucet will generally supply this PSI if turned
completely "ON".)
2. 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.)
Incoming water temperature must not exceed 125°F
for Model 2525, and 145°F for other models. Exces-
sive pump damage may result if the water tempera-
ture exceeds this acceptable level.
Damage to the equipment could occur. Never allow
the unit to operate without the incoming water line
attached and the water supply completely turned on.
