Operating instructiOns
sHutDOWn:
1. If the burner switch is still on, turn it off.
2. Squeeze the trigger and discharge the water for a period of three minutes
to cool the heat exchanger and high pressure hose. (Insufficient cool down
period of the high pressure hose will cause excessive wear and eventual
rupturing of the hose.)
3. Move the pump switch to the "OFF" position to stop the pumping unit.
If machine has the time-delay shut-down option, wait for timer to time-
out and shut machine off. See below for more information on time-delay
shutdown.
4. Trigger the gun momentarily to relieve trapped pressure.
OptiOns:
REMOTE BOXES
The remote box option allows the unit to be controlled from up to four remote
workstations. The remote stations are wired in parallel to allow the operator
to have full control of the unit from any station at anytime. Detergents are
controlled by a chemical solenoid added to the main unit and control switches
on the remote boxes.
The maximum run for the remote wiring are as follows:
4 Gauge Wire - 200 feet
6 Gauge Wire - 00 feet
TIME-DELAY SHUTDOWN
The time-delay shutdown option provides an adjustable automatic shutdown
for the main unit. The factory presets the time-delay shutdown interval at
2 /2 minutes. This option overrides the operation of the pump on/off switch
for control of the pump motor shutdown.
AUTO START/STOP
The auto start/stop option provides an adjustable automatic shutdown and
a pressure switch to restart the unit automatically when the gun is triggered.
The factory presets the time-delay shutdown interval at 2 /2 minutes. This
option is not available with remote box option or flow-activated unloader
option.
STEAM - 250°F
The 250°F steam option provides wet steam output from the unit. By adjusting
the steam valve on the main control panel for the unit and using the included
steam nozzle, 250°F steam is obtained. The sizing of the steam nozzle is
critical to proper operation of the option.
