WARNINGS

The M17 uses a variety of fuels. To prevent death, injury, fire or explosion, follow these rules;

DO NOT allow any flame producing material within 50 feet of unit.DO NOT smoke while mixing engine fuel or refilling fuel cans.DO NOT fill engine or heater fuel cans above weld line. Fuel can leak if overfilled.DO NOT prime carburetor when engine is hot. Fire or explosion may result.

Mix fuel in a well ventilated area, preferably outside.

Operate your equipment on a level surface only. If possible, position equipment so that water drains awayfrom the system.

Remove fuel cans and place on ground before filling.

The spray wands and injector will get extremely hot after two minutes of operation. To prevent injury,always wear protective gloves when operating the spray wands.

Always wear protective gloves when operating the M17 in cold weather.

The equipment gets very hot during operation. To prevent burns, avoid hot surfaces.

To avoid injury to personnel, do not operate the unit with protective panels or covers removed.

High noise levels exist during operation of this equipment. To prevent hearing loss, wear approved hearingprotection when standing within a 35 foot radius of the M17.

Verify that outlet ends of pressure hoses are secured before starting unit. Hose “whip” can cause injury.

Never operate showers with the FUNCTION SELECTOR switch in the WANDS position. Scalding hot waterwill injure personnel.

When in operation, the M17 emits carbon monoxide through the exhaust opening. To avoid sickness orcarbon monoxide poisoning, DO NOT stand in front of the exhaust opening. Stay upwind of equipment asmuch as possible. Always operate the M17 in a well ventilated area.

NEVER use a torch or open flame to thaw frozen components. Residual fuels/greases could ignite resulting ininjury and/or damage.

This equipment produces water pressure in excess of 100 psi. Verify that all pressure hoses and accessoriesare properly connected before operation. A connection that detaches can cause injury.

Ensure water hoses, shower bars, and spray wands are secure during operation. Severe injury may result ifaccessories detach during use.

Be sure a fire extinguisher is available when fueling and operating your equipment.

Fuel may have collected in burner. Attempting to restart unit with the burner full of fuel can result in injuryto personnel and damage to equipment. DO NOT attempt to restart unit after emergency shut down.

a

TM 3-4230-228-10

WARNINGS

To prevent injury to personnel and damage to the equipment, do not allow engine fuel to drip onto hot engineor burner components. Make sure a fire extinguisher is readily available.

The M17 pump/heater assembly weighs over 360 pounds. To avoid back injury, use a MINIMUM of fourpeople to move the unit. When loading onto a transport vehicle, use a MINIMUM of eight people or a loadingramp.

All fuels damage MOPP clothing. To prevent possible agent contamination, DO NOT let fuel touch MOPPclothing.

Do not let the suction hose strainer rest on the bottom of the water source. Ingestion of foreign matter canoccur and cause damage to the water pump.Avoid getting your gloves (mittens) wet during set-up operation and shut-down. Wet gloves can lead tofrostbite when operating in cold weather.

Do not open lock arms of camlock couplings when system is under pressure. Failure to comply may result ininjury to personnel and damage to equipment.

If temperature falls below 32°F (0°C) while performing your mission the following precautions should betaken to prevent getting your clothes wet and suffering cold weather injuries:

Avoid contact with water as much as possible.Stand upwind (if possible) of water spray.Use caution when connecting/disconnecting fittings.Use caution when adjusting control panel.

Remove rings, bracelets, wrist watch and neck chains before starting work. Jewelry can catch on equipmentand cause injury or may short across an electrical circuit and cause severe burns or electrical shock. Secureall loose clothing.

To prevent electrical shock, do not clean high voltage tripler while engine is running. Engine must be shutdown.

To prevent injury or illness, make sure the water tank oral inflator valve is clean before use. Remove all dirtfrom mouth piece using clean water. Use oral inflator ONLY when the hand pump is not available.

Never spray personnel with spray wands.

Carefully remove lid assemblies from fuel can openings to prevent fuel spills on skin, clothing or equipment.

If burner does not extinguish (go out) when FUNCTION SELECTOR switch (1) is set to OFF, performemergency shut down procedures (page 2-59). Notify your supervisor of the malfunction.

To prevent injury to personnel, allow system water to drain about one minute before unlocking couplings.

Be sure pressure hoses are properly connected. A connection that separates can cause fluid to spread over alarge area. Slipping hazards may result under freezing conditions.

b Change 1

TM 3-4230-228-10

WARNINGSTo prevent injury to personnel and damage to the equipment, unit must be shut down, waterpressure relieved, and water temperature allowed to cool before servicing the branch hose strainer.

Alternate fuel ball pump assembly (OMC) does not allow fuel to be drained from fuel lines bysqueezing bulb. Drain and relieve fuel line pressure by loosening hex head carburetor main jet,located at the bottom of the fuel bowl. Failure to do this could result in fuel being sprayed onpersonnel and equipment, causing injury or damage to equipment.

1-9. GENERAL

a. The pump/heater component of the M17 models comprisesseven functional areas: engine engine fuel system, electroniccontrol system, air system, heater system, heater fuel system,and water system. These systems provide a supply of pressurized,temperature-controlled water. After the system is operating, theoperator is required to periodically monitor the output watertemperature and fuel supplies.

b. No external power is required to operate the system.Only a source of water and fuel is needed. Operation is conduct-ed under two conditions: above freezing and below freezing.Operation may be conducted in the following three modes in eachcondition:

(1 ) Decontamination of material and equipment usingthe spray wands.

(2) Decontamination of material and equipment usingthe injector and decontaminant. At the presenttime, only a general purpose detergent is author-ized in the M17 models when using the injector.

(3) Provides showers for personnel.

1-10. ENGINE PRINCIPLES OF OPERATION

a. The 197cc engine is a one-cylinder, two cycle, air-cooled, power source that develops approximately 7.3 horsepowerat 4250 rpm. The 197cc engine on the M17, M17A1 has a built-ingenerator that suplies 6 vac (17 watts) to power the electroniccontrol system.

b. The 215cc engine is a one-cylinder, two-cycle, air-cooled, power source that develops approximately 8.0 horsepowerat 4250 rpm. The 215cc engine on the M17A2 and M17A3 produces 32vac (150 watts) to power the electronic control module via step-down transformer.

c. A manual recoil starter is used to start both engines.A centrifugal clutch drives the combustion air fan, water pump,and heater fuel pump. The clutch begins to drive the fan, waterpump, and fuel pump when engine speed exceeds 2700 rpm. A dia-phragm fuel pump, operating on pulsating crankcase pressure,supplies fuel to the engine carburetor.

1-14. HEATER SYSTEM PRINCIPLES OF OPERATION

The heat exchanger is a double-walled, convection type unit. The functional components consist of a burnerand a heating coil. The burner is fired by an electronic ignition system through an igniter plug, Pressurizedfuel is received and atomized by the burner fuel jet. Air is received in the burner from the fan, mixed with theatomized fuel, and ignited. The heated air is then forced around the water coils to heat the water and then outthrough the exhaust side of the heat exchanger.

1-15. HEATER FUEL SYSTEM PRINCIPLES OF OPERATION

Fuel is supplied to the burner from the five gallon (18.9 liter) fuel can through a strainer and fluid filterassembly by the engine driven fuel pump. The fuel then passes through the magnetic valves to the burnerfuel jets. Excess fuel is routed through the check valves back to the fuel can. The system operates on theprimary jet until there is a need for higher water temperatures; at that time, fuel will be routed through anadditonal, secondary, fuel jet to increase burner output.

NOTEThis diagram illustrates principles of operation ONLY. It is not an exact representation ofthe equipment.

TM 3-4230-226-10

1-16. WATER SYSTEM PRINCIPLES OF OPERATION

The water system consists of an over-capacity, roller-type pump that is belt driven by the engine through thecentrifugal clutch. The pump can provide varying flow rates at the outlet and is controlled by an automaticwater pressure regulating valve. The water pressure regulating valve will allow any oversupply of water tobe returned to the inlet side of the pump.

Two flow switches, mounted in the coil inlet assembly, sense system water flow. The signals sent by the flowswitches are received by the electronic control module, which controls burner ignition and output. Duringperiods of high water flow (showers or injector in use or both spray wands actuated), both jets in the burnerare activated. During periods of low water flow (only one spray wand actuated), only one burner jet is used.

NOTE

The burner will ignite when spray wand triggers are squeezed, and will go out when released. Burnerignition is automatic in both SHOWER and WAND modes.

WARNINGThe heater uses a variety of fuel. To prevent death, injury, fire or explosion, follow these rules:

DO NOT smoke when mixing fuel. DO NOT allow flame producing materials within 50 feet durinfueling.DO NOT fill fuel can past top weld line. It could leak.Remove heater fuel can from pump/heater assembly frame and place on ground during refueling.All fuels damage MOPP clothing. To prevent possible agent contamination, DO NOT let fuel touchMOPP clothing.Perform fueling operations in well ventilated area, preferably outside.

NOTEThe burner uses as primary fuel, leaded or unleaded gasoline. Alternate fuels include: kerosene, jetfuel, diesel fuel, or any mixture of these. Because of the lower volatility of the alternate fuels, igniticof the burner assembly at temperatures below 80°F may be difficult and result in wet fouling of theigniter. When the surrounding air temperature is below 80°F, the primary fuel, gasoline, will be useuntil operating temperature has been achieved (about 5 minutes). Thereafter, one of the alternatefuels may be used.

Burner will operate about one-half hour on five gallons of fuel.

Shutdown in Freezing Weather (page 2-59)Thawing Procedure (page 2-60)

If temperture falls below 32° while performing your mission the following precautions should be taken toprevent getting your clothes wet and suffering cold weather injuries:

Avoid contact with water as much as possible.Use caution when connecting/disconnecting fittings.Stand upwind (if possible) of water spray.Use caution when adjusting control panel.

CAUTIONIn an emergency, (actual decontamination mission), if 2-cycle oil is not available, SAE 30 nondetergentoil may be used. The use of SAE 30 oil, however, will reduce engine life and increase maintenancerequirements.

In freezing weather, the M17 water system will freeze in a matter of minutes. If engine operation cannotbe established quickly, proceed with thawing procedures.

In extremely cold weather (100oF or lower), it is necesary to preheat the system by circulating warm anti-freeze through the pump to prevent freeze up. Perform steps 1 through 19 of Storage in Freezing Weather.Circulate warm antifreeze for at least 3 minutes to assure all inner surfaces are adequately thawed

If you expect that your next mission will be performed in below temperture or that theequipment will be stored in below temperature, perform Storage in Freezing Weather.

In cold weather, add icing inhibitor (Alcohol, Denatred) to the engine and burner fuel. Use l/12 to 1 pintof icing inhibitor to 5 gallons of fuel.
