draw clean water through the chemical hose
and pressure washer to rinse the internal

Standing Water
Source
To draw water from a standing source:
1. Attach the supplied input hose filter to the
input hose and place the input hose filter in
the standing water source.
Note: Be sure the water source is free from
debris which could clog the filter and cause
a loss of water flow.
2. Prime the pump by pouring water into the
other end of the input hose (the end without
the filter) while the filter end is submerged in
the water source. Without spilling water out of
the hose, connect the input hose to the input
port on the pump.
Note: Be sure the water source is large
enough to provide 5 GPM of flow for the
duration of the pressure washer operation.
NOTICE
If the pump is not able to provide pressurized
water when drawing from a standing water
source, shutdown the pressure washer
immediately and re-attempt to prime the
pump. Failure to follow this instruction can
damage the pump and void the warranty.
