IMPORTANT SAFETY INSTRUCTIONS
1. Read all safety and operating instructions before using the unit.
2. Read all electrical hook up instructions.
3. Read warnings on additive containers.
4. Ventilate work area when using toxic or pungent additives to reduce your exposure to
toxic fumes.
5. Use protective wear, especially for the eyes and skin.
6. Be careful of slippery floors. Some additives make a normally safe area extremely
slippery and dangerous.
7. Keep children away from the machine and wash area.
8. Do not change nozzle size. Each machine is designed to operate with a specific size
nozzle. An incorrect nozzle could cause excessive pressure resulting in pump damage
and possible personal injury. Refer to parts list for correct nozzle size.
9. Do not point the nozzle where damage or injury cold result (eg. eyes, skin). The water
discharge from this unit is under extremely high pressure.
10. Do not point the nozzle toward an electrical outlet as you risk severe shock and personal
injury.

PRE-OPERATING INSTRUCTIONS
When unpacking the unit, if you find damage due to shipping, contact your dealer or Mi-T-M
Corporation immediately,
ELECTRICAL SUPPLY
Arrange with an electrician to install a properly grounded, three phase service. To protect the
receptacle from splashes, the recommended height above the ground level is a minimum of
four feet. A ground fault interrupter (GFI) should be used. Make sure the supply voltage is
correct. The voltage is shown on the rating plate of the unit, or see “Specifications, Features
and Options” sheet in this manual.
IMPORTANT!
DO NOT CHANGE THE AC PLUG ON THE UNIT TO A DIFFERENT TYPE DO NOT CUT
OFF THE GROUND PIN OR THE OPERATOR WILL BE EXPOSED TO SEVERE SHOCK.
KEEP ELECTRICAL CORDS AND CONNECTIONS DRY AT ALL TIMES.
INCOMING WATER SUPPLY
Connect a garden hose to the water inlet of the unit. The water supply must be able to deliver
5-8 gallons per minute at a minimum pressure of 5 psi. See “Specifications, Features and
Options” sheet in this manual.
HIGH PRESSURE NOZZLE
Attach the high pressure nozzle (sent with operator's manual), to the trigger gun extension.

SAFETY COMPONENTS
FLOW SWITCH
The flow switch prevents the burner from being turned on if there is insufficient water. Proper
water flow causes the magnetic core to be pushed up, causing the reed contact to close. This
contact is interlocked with the main heater contactor.
UNLOADER VALVE
The Unloader allows all of the water delivered by the pump to return to the pump suction
side. If the trigger gun is closed (shut) the valve goes into the “bypass mode”. The pump
runs without pressure. However, the pump may be SEVERELY DAMAGED, due to excessive
overheating, if left running in the “bypass mode” or “Gun-Off” situation for more than 6 minutes.
SAFETY RELIEF VALVE
The Relief Valve prevents the machine from being subjected to abnormally high pressures. If
this situation occurs, the valve will blow off relieving the pressure in the coil. This valve may
also operate if the unloader is adjusted too high.
THERMOSTAT
The built-in thermostat stops the unit from overheating. Maximum temperature of the unit
is 300° F. (150° C) Above this temperature, the thermostat contactor turns off the third set
of heaters.
LOW PRESSURE SWITCH
The Pressure Switch ensures that there is pressure, and therefore there is water flow at the
head of the pump. This control does not operate at less than 3 psi. Therefore if the water is
turned off, the machine will not operate.
HIGH LIMIT SWITCH
The high limit switch is a thermostat which operates at a higher temperature than the
thermostat, about 305° F (150° C). This switch is not adjustable and will only operate when the
other controls fail to keep the water temperature within the normal operating range. This switch
cuts the power to all of the heaters.
FUSIBLE PLUG
The fusible plug is a safety relief device designed to operate at about 380° F. At this
temperature it should only blow off if all of the other safety devices have failed. This is a one
time device and must be replaced if it releases. More importantly, the cause of this blow off
must be determined before refitting the machine.

THINGS TO CHECK REGULARLY
1. Check for SYSTEMS LEAKS. Leaks in the pressure side of the system can cause premature
wear (or even failure) of the pump. The WARNING signal for this kind of leak is “frequent”
cycling of the Unloader. (“FREQUENT” means more than once every 2 minutes in the
“Gun-Off” position.) Check the gun and swivel joints for leaks.
2. Check the OIL LEVEL at least once a week. Add ONLY the type and grade of oil specified for
this pump. (See Parts List.)
3. CHANGE OIL as recommended.
4. After you use chemical additives, thoroughly FLUSH the system with clean water.
5. Inspect the POWER CORD regularly. Also check the POWER OUTLET SOCKET.
For safety, replace worn or damaged parts immediately.
6. Never run the washer without water. TURN WATER ON FIRST.
7. PROTECT FROM FREEZING! When transporting your washer in temperatures below 32°F
(0°C), WINTERIZE the pump, hoses and gun.
WINTERIZING YOUR PRESSURE WASHER
1. Shut off the water supply and disconnect the hose at the water source.
2. Put the end of the water hose into a 4 litre jug of windshield washer anti-freeze.
3. Turn on Cleaner and open gun until liquid comes out of nozzle "foamy" or "soapy".
CAUTION: If your high pressure hose is longer than 26 feet, the 4 litre bottle of
anti-freeze may empty before liquid from the nozzle gets foamy.
4. Put gun in "OFF" position for 5 seconds to get anti-freeze into bypass line. Shut
off motor.
5. Disconnect the water hose at the machine.
6. The unit, pressure hose and gun are now winterized.

SERVICE AND MAINTENANCE
Before carrying out maintenance work or repairs, disconnect the plug from the power supply.
MAINTENANCE SCHEDULE:
WEEKLY:
Check the oil level of the high pressure pump. If the oil is milky or the oil level is below the minimum
mark, change or fill with SAE 20W or 30W non-detergent oil.
YEARLY:
Oil Change: Remove the drain plug of the water pump, drain the oil, and clean and replace the drain
plug. Fill oil up to the red dot inside the oil glass (Use SAE 20W or 30W non-detergent oil).
Coil Maintenance: Liming of the coils is caused by mineral deposits from the water and occurs in
hard water areas. The deliming procedure requires special caution and tools. It is recommended
that the local service person is contacted if problems arise.
Checking For Scale or Liming in Coil
1. Remove outlet orifice and check for liming. Clean orifice if needed.
2. Remove outlet gun.
3. Install a pressure gauge between the water pump and coil inlet.
4. Check condition of your water pump and unloader valve. Water pump and unloader valve
failure will cause low pressure readings.
5. Turn on pump without water outlet gun or outlet orifice. If pressure reading is above 50 psi,
have your machine descaled.
6. If your machine is satisfactory, reassemble.
Descaling: If pressure drop of over 50 psi is experienced in the coil, descaling is recommended.
Descaling requires the use of highly corrosive chemicals as well as the use of special protective
clothing.
1. Have a 20L pail of descaling chemical available.
2. Plumb the pump section into the pail of descaling compound with a screen on the end of
the suction line.
3. Plumb a hose from the machine outlet back into the pail of descaling compound.
4. Turn the pump on and circulate the compound through the machine for about 20 minutes.
5. After that time the chemical being pumped out of the coil should be running thin and dirty
rather than foaming heavily.
6. Remove the extra plumbing and reconnect machine together and run clean cold water
through the machine for five minutes.
