Sanitech Mark I Operating Instructions

OPERATING INSTRUCTIONS FOR NATURAL GAS
PART 1 : SETTING UP THE MACHINE
1. Connect the garden hose to the faucet and the machine.
2. Connect the extension cord to the electrical outlet and the machine. The extension cord should be
50 feet or less and the gauge should be 14 or 12.
3. Connect the steam hose to the machine. Connect the steam wand to the steam hose.
4. The gas company should have already connected the unit to the gas line using a ball valve, a gas
regulator and a 6' flexible hose. Open the ball valve so gas is available and shows 2-2.5 on the gauge.
PART 2 : TURNING THE MACHINE ON
1. Turn the water on at the faucet. Open the trigger gun by pulling the handle.
2. You must let the water run with the trigger gun open for at least two minutes to get all the air out of
the heat coils. Put the green or white nozzle (found in the parts box) on the end of the wand.
3. Turn the pump switch "on". Pressure will be generated. Wait 30 seconds before the next step to be
sure all the air is out of the coils.
4. With the trigger gun open, turn the ignition switch "on". You should hear a slight "click" sound. This
sound shows the machine is trying to ignite.
5. The unit will not ignite the first time you turn the ignition switch "on". Air is in the gas lines and it
needs to be purged. Leave the ignition switch on for 10 seconds and turn it back "off". Then turn it
back "on". Wait another 10 seconds and turn off. Repeat this process until the machine ignites.
NOTE: The trigger gun has to be open and the water flowing any time you are trying to ignite the unit.
PART 3 : SETTING THE TEMPERATURE
1. A good temperature for degreasing and cleaning without using any chemicals is 230°-240°f.
2. The machine should have been ignited at 2psi. The temperature will slowly increase.
3. When the increase has stopped if you are below 240° increase or decrease the fuel pressure by ¼ psi .
Do this until you have stabilized the desired temperature.
4. The fan nozzles (green, white & optional yellow) will maintain a sharp cutting edge up to 250°.
After this temperature the flat spray will start to "vaporize" or become more rounded. If you wish to
Sanitize at temperatures above 250° we recommend that you use the zero degree red nozzle and
increase the fuel flow until the desired temperature is achieved.
PART 4 : CLEANING WITH THE SANITECH
1. The Sanitech cleans primarily with temperature. It does not try to blast the surface clean with large
water volumes and extremely high pressure. Get the nozzle as close to the surface as is necessary to
remove the grease or other substances that you are cleaning.
2. Once you have established the correct distance clean as quickly as possible using a "back and forth"
motion. Areas that are being cleaned for the first time might require a slow initial cleaning. Followup
cleanings can be done much more rapidly.
3. Try to use the trigger gun as infrequently as possible. Each time you close it the heat goes off. When
you reopen the gun the ignition will come on in 1-3 seconds. During this time cold water is being
pumped thru the coils. Constant "on & off" will make it difficult to maintain a good temperature.
