The unit is protected by a Thermoshield Dump Valve which will automatically dump
water to the ground if the internal water temperature rises to a point where it can
damage seals. This happens if the machine is left too long in by-pass (machine is
running, but not used.)
REMEMBER: Check Oil Levels DAILY!
INDICATOR LIGHTS
The GREEN indicator light indicates power to the unit is on
The RED indicator light is a fuel indicator and will come on when the onit runs out of fuel
and shuts down. Refuel.
When the unit is switched on and if it makes a humming sound, switch off immediately!
This means the power to the unit is too low. Using long power extension cords can be the reason
and should not be used. Always plug straight into mains power socket.
OPERATING/CLEANING TIPS:
1. Using a Fan Jet, first blast off heavy soil or dirt build-up. The unit comes standard with a
15 degree nozzle correctly sized for the pressure and flow for your machine. Always use
the same size nozzle (NEW) to test the machine for performance
2. Apply detergent to partially cleaned surface using low pressure. (Apply detergent by
spraying from bottom up to avoid streaking - using a dual-lance and detergent assembly.)
Allow to soak for a few minutes.
3. Blast off dirt using high pressure and a 'bottom - up' approach.
4. Lastly, rinse off thoroughly with 'top down' approach.
SHUTTING DOWN:
IMPORTANT
– ALWAYS turn boiler off first (by turning the red Heat Control Switch to the ‘0’
position) and run cold water through the system by blasting with cold water for 3-5 minutes before
shutting down!
Turn power supply off by pressing the rubber booted ON/OFF switch to OFF
Disconnect from mains power socket.
Turn off water supply. Disconnect unit from water supply
Squeeze gun several times to release any stored pressure
Lay out high pressure hose straight and then reel back up onto reel.
This unit is protected by:
Timed By-Pass Shut-down (Automatically shuts down if left too long in by-pass)
Supply water over temp shut-down
Low fuel shut-down
Low water supply instant shut-down
REGULAR CHECKS:
Oil Level on the pump!
Water Supply
- Low water supply can cause cavitation and/or pump running dry casing
expensive pump failure. Always check to ensure supply is:
o
Uninterrupted
o
Pressure is good (10 PSI / 30 LPM)
o
There are no kinks in supply hose
o
Fittings are in good condition and not leaking
Worn Jets
-System will function okay, but with oversized, worn jets, the pressure will be
much lower and cleaning ability reduced. Always use new jets to check operation
efficiency
