NOTE
: Natural gas option; this model needs to be vented.
6.) Connect the LP gas hose to the connection on the control panel. Make sure it is
completely connected before continuing.
7.) Open the main fuel valve completely located on top of the LP gas tank. If any
leaks are suspected, check for bubbles by covering the connection with soapy
water.
8.) Keep the gas pressure low on the fuel pressure gauge at this time. If the pressure
is too high, adjust the red regulator counter-clockwise (upward) to reduce the
pressure. You should start the machine with about 2-3 lbs. of fuel on the larger
models and 1-2 lbs. on the Ultra 250 and Ultra 600.
9.) Keep the gas pressure low on the fuel pressure gauge at this time. If the pressure
is too high, adjust the red regulator counter-clockwise (upward) to reduce the
pressure. You should start the machine with about 2-3 lbs. of fuel on the larger
models and 1-2 lbs. on the Ultra 250 and Ultra 600.
10.) Turn the cold-water supply source on completely.
11.) Squeeze the trigger on the wand allowing the water to come through the gun.
12.) Turn the PUMP switch “ON” and let the machine run until the pump runs
smoothly and the water isn’t sputtering. To speed the process up you can close
the trigger gun for about 10 seconds and open again. This will help bring the air
to the front of the wand.
SHUT DOWN:
1.) Turn off the ignition switch.
2.) Let the pump continue to run until the water cools down and the temperature
gauge reads
3.) About 100° F
4.) Turn off the pump, close the LP gas valve on the tank.
5.) Turn off the water and disconnect the electricity.
6.) Store the unit where it will not be subject to freezing temperatures as this will
destroy the pump, coils and/or the flow switch.
a.) If this cannot be done:
WINTERIZE THE UNIT:
1.) The Ultra 250 and Ultra 600 require: 1 gallon of windshield wiper fluid or anti-
freeze.
2.) The Ultra 1000 and Ultra 1300 require: 2 gallons of windshield wiper fluid or
anti-freeze.
