WARNING
• Do not install steam cleaner in areas containing flammable material or gases. Severe injury or death from fire or fumes may result.
• Install steam cleaner in properly ventilated areas to avoid possible insufficient supply of oxygen. If poorly-vented area is a necessity, outside air may be piped to oil burner assembly and a fan may be installed to bring fresh air into the area.
• For inside installation, use exhaust stack to prevent fumes from collecting inside build-ing. Minimum exhaust stack is 10 inches (25.40 cm). Exhaust stack must be warm for sufficient draw; in cold areas of operation, exhaust stack should be insulated. Cold exhaust stack invites downdraft. Severe injury or death could result if exhaust is not vented.
• Items to be cleaned should be approximately 12 feet (3.66 m) from steam cleaner to avoid direct spray of steam cleaning gun coming into contact with steam cleaner.
Excess moisture reaching generator and electrical controls will reduce life of steam cleaner unit and components and may cause shorts which may result in electrical shock.
• Diesel fuel is FLAMMABLE; DO NOT smoke in vicinity while performing servicing operations. Severe injury or death may result.
• Ensure generator is properly grounded before operating steam cleaner to avoid electri-cal shock.
CAUTION
Incoming power supply must be 208 VAC ±10%, 50/60 Hz, single phase; otherwise, equipment damage can result.
a. Installation Site Precautions.
(1) Steam cleaner should be located on a level surface with consideration given to accessibility for filling of cleaning solution and fuel oil. Location for electricity, water connec-tions, and maintenance should also be consid-ered. If generator set will be used, ground generator set before operation. Refer to TM 5-6115-615-12.
(2) Ensure steam cleaner is properly stabilized before operating. Turn leveling-support jack crank handle (1) clockwise to raise flat bed trailer (2) and disengage it from towing vehicle. Turn leveling-support jack crank handle (1) counterclockwise to lower and stabilize the flat bed trailer (2).
(3) Go to the opposite end of flat bed trailer (2). Lift handle (3) to release rear stabilizer (4) from the travel position. Turn base of leg assembly (5) as necessary to adjust height of rear stabilizer (4) to ensure solid contact with the ground while in the locked position.
(4) When using commercial power source, steam cleaner should be wired to a fused- or breaker-protected electrical grounded circuit or outlet of at least 20 amp capacity.
b. Initial Checks and Services.
NOTE
For initial checks and services of generator set, refer to TM 5-6115-615-12. For initial checks and services of flat bed trailer, refer to TM 9-2330-202-14&P.
(1) Check fuel gauge (1). If necessary, remove fuel tank cap (2) and add proper grade of diesel fuel. Use grade 1 (item 10, appx E) at 32°F (0 °C) and below; use grade 2 (item 11, appx E) above 32°F (0 °C).
b. Initial Checks and Services. (cont)
(2) Open fuel shutoff valves (3 and 4).
(3) Check that float (5) in water tank assembly (6) operates freely.
(4) Check all fuel lines for loose connections and leaks.
Ensure liquid storage tank is positioned as shown.
(5) Remove webbing strap (7) and liquid storage tank (8). Remove cap (9) and fill liquid storage tank with cleaning compound (item 7, appx E). Reinstall liquid storage tank and webbing strap.
(6) Using cross-tip screwdriver, remove access cover (10). Using flashlight, check oil level in water pump assembly (11). Add oil (item 14, appx E) as required.
b. Initial Checks and Services. (cont)
When using generator power, observe correct hookup of cable to prevent damage to equipment.
(7) If using commercial power, connect facility power cable assembly (12) to commercial power source. If using generator power, ensure that generator power cable assembly (13) is con-nected to generator terminals (14). Refer to TM 5-6115-615-12.
(8) Attach wash hose assembly (15) to steam cleaner pipe coupling (16) and attach steam cleaning gun (17). Do not attach a nozzle when performing the Initial Start Up procedures in para-graph c., following.
c. Initial Start Up. The following steps provide steam cleaner initial starting procedures.
WARNING
Always use ear protection. During operation, the generator set exceeds permissible decibel levels. The steam cleaner also exceeds permissible decibel levels during operation in the steam mode and during blowdown. Failure to observe this warning could result in permanent hearing injury.
Wear safety goggles/glasses and gloves to prevent injury when operating the steam cleaner in any mode.
CAUTION
Do not use the steam cleaner in any mode on surfaces having a petroleum-based undercoating. Otherwise erosion/removal of such undercoating can result.
NOTE
Read through operating procedures prior to operation.
(1) If steam cleaner is to be operated from a pressurized water source, perform the following steps:
(a) (b) cleaner.
Open exhaust flap (1).
Connect pressurized water hose assembly (2) to water inlet assembly (3) on steam
c. Initial Start Up. (cont)
(c) (d) (e) (f (g) (h) (i) (j)
Ensure coupler cap (4) is tightened securely.
Rotate ball valve (5) to ON position.
Turn on water supply and fill water tank assembly (6).
If present, remove nozzle from steam cleaning gun (7). Open trigger (8).
Check that the CHEMICAL METERING valve (9) is in the closed position.
If using generator power, refer to TM 5-6115-615-12 and start generator set.
Check that EMERGENCY OFF circuit breaker (10) is in ON position.
Rotate MODE SELECTOR (11) to COLD.
CAUTION
Keep water and steam away from the oil burner electromagnet relay. Moisture can permanently damage internal parts.
(k) Press PUSH TO START switch (12). Steam cleaner should start immediately.
(l) When a steady stream of clear water is discharged from steam cleaning gun (7), steam cleaner is flushed and ready for operation.
(2) If steam cleaner is to be operated from a nonpressurized water source, perform the follow-ing steps:
(a) Open exhaust flap (1).
(b) Unscrew coupler cap (2) and connect suction hose assembly (3) to water pump assem-bly (4).
(c) Rotate ball valve (5) to OFF position.
(d) Place foot valve/strainer end of suction hose assembly at least 6 in. (15 cm) below water surface.
(e) If present, remove nozzle from steam cleaning gun (6). Open trigger (7).
c. Initial Start Up. (cont)
(f) Check that the CHEMICAL METERING valve (8) is in the closed position.
(g) If using generator power, refer to TM 5-6115-612-12 and start generator set.
(h) Check that EMERGENCY OFF circuit breaker (9) is in ON position.
(i) Rotate MODE SELECTOR (10) to COLD.
CAUTION
Keep water and steam away from the oil burner electromagnet relay. Moisture can permanently damage internal parts.
(j) Press PUSH TO START switch (11). Steam cleaner should start immediately.
(k) If water pump does not prime within 3 minutes, stop steam cleaner by rotating MODE SELECTOR (10) to OFF. Refer to Table 3-1, Operator Troubleshooting.
