Hot Water Operation; Cleaning With Detergents - Mi-T-M Corporation HG Série Mode D'emploi

OPERATING INSTRUCTIONS

HOT WATER OPERATION:

1. Follow the steps outlined for "COLD WATER OPERATION."
2. Move the burner switch to the ON position. On initial start-up, water will
begin turning hot in approximately 60 seconds and will reach maximum
temperature in approximately 3 minutes, provided the trigger remains
squeezed. The burner will stop firing when the trigger is released.
3. Set thermostat to the desired setting.
At this point, the unit is operating as a hot water pressure washer. Be certain
to be extremely cautious when adjusting the pressure and controlling the
trigger gun/dual lance assembly to avoid the possibility of burns.
NOTE: The burner is equipped with a safety lock-off device. If the pilot fails
to ignite within 60 seconds, the gas valve locks OFF. Simply release
the trigger for approximately another 60 seconds and repeat. During
operation, the burner may cease and start occasionally because of
the thermostat setting.

CLEANING WITH DETERGENTS:

This feature is designed for use with mild detergents only. Since the cleaning
solution travels through the heat exchanger coil, do not use corrosives as
they will cause extensive damage as well as pose a considerable safety
hazard.
1. Be certain to wear protective safety attire as stated on pg. 18.
2. Prepare detergent solution according to label directions. (Never pump
acids, alkalines, abrasive fluids or solvents through the unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the
detergent solution.
4. Adjust the amount of detergent desired by turning the detergent adjustment
knob to the desired setting.
5. To apply solution, unlock the trigger gun and squeeze the trigger. In a few
moments a detergent/water mixture will exit the nozzle. Start spraying
the lower portion of the surface being cleaned and move up, using long
overlapping strokes. Applying from the bottom up helps avoid streaking.
Allow to soak briefly. Avoid working on hot surfaces or in direct sunlight
to minimize the chances of the detergent drying, which may result in
damaging surfaces. Be certain to clean a small section at a time.
6. To rinse, 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.
NOTE: If machine is equipped with remote box (es), read pg. 24 for information
on detergent solenoid.
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 by 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.
