6. To rinse, press DOWN on the Detergent Switch to take the unit out of
detergent mode or turn the detergent adjustment knob to the OFF position.
It will take about 30 seconds to purge all detergent from the line. For best
rinsing results, start at the top and work down.
7. Siphon a gallon of water through the detergent system after each use. This
prevents the possibility of corrosion or detergent residue causing mechanical
problems during the next use.
NOTE: The detergent adjustment knob or detergent solenoid MUST be
turned to the OFF position when not in use or when the strainer is
not totally submerged in solution. If not, the pump will lose its prime
resulting in no spray discharge at the nozzle. This condition will
damage the pump over an extended time period.
SHUTDOWN:
1. If the burner is still on, Press DOWN on the Burner Switch to turn it OFF.
2. Squeeze the trigger and discharge water for a period of three minutes to
cool down 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. Press DOWN on the Pump Switch to stop the pumping unit. This will also
take the unit out of Burner and Detergent mode.
4. Trigger the gun momentarily to relieve trapped pressure.
FEATURES:
AUTO START/STOP
The auto start/stop feature provides an automatic shutdown utilizing pres-
sure switch to restart the unit automatically when the gun is triggered. The
factory presets the time-delay shutdown interval at 18 seconds.
TIMER LOCKOUT
The timer lockout feature locks the unit out from automatically starting if the
unit has not been used for 2 minutes. It does this by requiring the unit to be
used continuously for over 10 seconds in order to reset the lockout timer.
This will stop the unit from repeatedly restarting all day when the system has
a small leak such as a leaky gun.
When the unit enters timer lockout mode, the light on the Pump Switch will
turn off. To restart the unit, simple press UP on any of the Pump Switches
(local or remote).
REMOTE BOXES
The remote box option allows the unit to be controlled from remote stations.
The remote stations are wired in parallel to allow the operator to have full
control of the unit from any station at any time. 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:
14 Gauge Wire - 200 feet
16 Gauge Wire - 100 feet
STEAM – 250°F
The 250°F steam option provides wet steam output from the unit. By ad-
justing 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.
