injection, push the nozzle at the end of the high pressure wand forward. This
nozzle position delivers low pressure [200 PSI (13.8 BAR)] and automatically
activates the siphon injector to apply chemical or soap. It takes several seconds
for the chemical or soap to travel through the high pressure hose to the nozzle.
To stop soap application, pull the nozzle back.
MIXING RATIOS: GPW-1200/GPW-1000/GPW-1000-P
The mixing ratio of chemicals to water depends on the viscosity of the chemicals
being used. The mix ratio for watery liquids is approximately 1 part chemical or
soap to 20 parts water when low pressure spray is used.
If a chemical is to be mixed with water in a ratio of 100:1, premix 1 part chemical
with 4 parts of water in the tank.
The spray nozzle is adjusted to low pressure setting. The diluted chemical is now
mixed in a ratio of 20:1 with water which corresponds to a ratio of 100:1 of the
undiluted chemical.
For mix ratio of 1 tablespoon per gallon of water, prepare a premix solution of
1 part chemical to 10 parts of water.
For mix ratio of 1 teaspoon per gallon of water, prepare a premix solution of
1 part chemical to 30 parts of water.
A low pressure spray without chemical injection is obtained by opening spray
nozzle and removing dip tube from soap container.
WARNING: Applying strong acid or caustic solutions with a pressure washer is
not recommended and voids the warranty.
MIXING RATIOS: GPW-2003/GPW-2502
The mixing ratio of chemicals to water depends on the viscosity of the chemicals
being used. The mix ratio for watery liquids is approximately 1 part chemical or
soap to 25 parts water when low pressure spray is used.
If a chemical is to be mixed with water in a ratio of 100:1, premix 1 part chemical
with 3 parts of water in the tank.
The spray nozzle is adjusted to low pressure setting. The diluted chemical is now
mixed in a ratio of 25:1 with water which corresponds to a ratio of 100:1 of the
undiluted chemical.
