SAVE THESE SAFETY
INSTRUCTIONS
1. LOCATION: This machine should be installed by
only qualified technicians. The machine should be
setupon a level surface whereit will notbe affected
by strong winds, rain, snow, extreme heat, and
freezing temperatures. Install the machine
considering locations for chemical pick-up, fuel
connections,electrical connections, water hook-up,
venting,andmaintenance.
All wiring and electrical connections should comply
withtheNationalElectricalCode(NEC)andwithlocal
codesand practices. Usethechart on thenext page
foryour cord selection

2. WATERCONDITIONS: Localwaterconditionsaffect
the coil adversely more than any other element. In
areaswheretroublesome conditions may existwith
like equipment (such as water heaters), we
recommendthe use of a watersoftener.
3. VENTING: This machine emits carbon monoxide, a
deadlygas,andmustbeventedifusedinanenclosed
area. Improperventingcan cause poor combustion,
delayed ignition, down drafts, and the possibility of
freezing the coil. Contact your distributor or local
heating and air conditioning dealer for proper
materials.Localcodes must beobserved.
4. WATER SUPPLY: This machine must have a water
supplymeetingorexceedingthemaximumdischarge
volume and a minimum water inlet pressure of 10
PSI/ 0.68 BAR.
5. BARRIER: We recommend a barrier be installed
between the machine and wash area to prevent
moisturefromcoming in direct contactwithelectrical
controls,motorsandtransformers. This will increase
themachine’s lifeand lessen electrical problems.
6. FREEZING: This machine must be protected from
freezingaccordingtoSTORAGEsectionofMACHINE
MAINTENANCE.
7. COLD WEATHER: As the weather becomes colder,
fuel becomes thicker and may become so viscous
that the fuel will not flow properly. As viscosity
increases,the thicker oilcan cause delayedignition,
poorspraypatterns, and rumbling fires. Asmoisture
will quickly destroy fuel pumps, make certain that
tankopeningsare secure andmoisturecannot enter.
Incold weather areas, frost buildup will occurin fuel
tanks.Asthe weather warms itturnsto condensate,
andthe water willbe in thetank. Keep the tankclear
of water, as moisture reaching the fuel pump will
cause rust, and the pump will bind. A full fuel tank
will lessen condensation build up.
8. CHEMICALS: Mix chemicals per the chemical
manufacturersprinted directions. Follow all mixing,
handling, application, and disposal instructions.
Weargloves,boots, goggles, and protectiveclothing
appropriatefor the chemicalbeing used.

WATER INSTALLATION
1. WATER TEMPERATURE VARIATION: On
machines not equipped with a temperature control
device, the temperature of the discharged water is
dependanton the incomingwatertemperature.Some
minor adjustmenttothe fuel inputmaybe required if
the incoming water is significantlY different than 50
degreesfahrenheit.
2. WATERCONDITIONS:Localwater conditions affect
thecoil andspray tip more adversely thanany other
element.Inareaswheretroublesome conditions may
exist with like equipment (such as water heaters),
werecommend theuse of a water softener.
WARNING: Thismachine emits carbon monoxide,
and deadly gas, and must be vented if used in an
enclosed area. Improper venting can cause poor
combustion, delayed ignition, down drafts, and the
possibilityoffreezingthe coil. Contact yourdistributor
orlocalheatingandair conditioning dealer for proper
materials. Local codes must be observed.

type that meets all codes for capacity and
materials. Mount the draft diverter directly to
thestacking flangeon themachine.
C. The draft diverter’s function is to insure that the
barometric pressures are as close to the same
as possible at the air inlet and outlet to the coil
and will not be changed by either up drafts or
downdrafts.
D. Installation of a draft diverter WILL NOT
PREVENT THE COIL FROM FREEZING. In
areas where freezing temperatures are
common, some type of down draft prevention
mustbeused. Checklocalcodesforacceptable

4. TOAPPLY CHEMICAL:
Upstream Chemical Injection
When injecting chemicals “upstream” what you are do-
ingis introducing chemicalsto the waterflowas it enters
theactualpumpinletandrequiresa float tank. The popu-
larity of this type of chemical injection is due to the fact
thatthis allowschemicals to be applied atfull pressure
amajoradvantageforproductivity.
Downstream Chemical Injection
Mounted to the outlet of the pump or the coil a down-
stream injector introduces chemicals to the water flow
AFTER it leaves the pump or the coil. This effectively
eliminates the major risks of exposing the inner work-
ings of a pump to harsh chemicals. When chemical is
desired, the system must be switched over to the low
pressure nozzle to draw chemical.
A. Engagethe trigger safetylatchon the spraywand.
Pull back the Quick-Connect collar on the end of the
wand and remove the tip. Now insert “black” tip into the
fitting, and release the collar. You can draw chemical
only with the “black” low pressure nozzle.Tug on spray
tip to make sure the connection is secure. Rotate to
desired spray angle. For most effective cleaning, keep
spray tip from 8 to 24 inches away from the cleaning
surface.
B. Insert chemical screen into chemical container.
C. Turn the burner switch to the “off” postion.
There will be air in the chemical line. Air heats very
quicklyandneedstobeeliminated before the burner can
beturnedon.Openthemetering valve counter clockwise
withthe triggergun openallowing the chemical to come
upthe chemicalline. Chemical should begin movingup
the chemical line. Once the chemical line is completely
full, trigger the gun on and off numerous times to break
any possible air locks. Turn burner system switch to
“on”position.
D. If the gun assembly is equipped with variable or
multiple nozzle assembly, adjust to low pressure.
E. If the gun assembly is equipped with a dual lance
wandopenthe valve.
Do not allow the detergent to dry on the surface
(preventsstreaking).

NOTE: In process of making steam, the water flow
through the coil has to be decreased. The amount of
water is determined by the pressure and water
temperature of your location.
If the incoming water temperature is as high as 70°F,
the amount of water going through the coil has to
decrease very little.
If the incoming water temperature is as low as 40°F,
the amount of water going through the coil has to be
decreased.
The water temperature is relative to the season
variation and should be taken in consideration when
operating steam.
The 2 systems used to create steam they are the high
volume and low volume system. The high volume
system uses a regulating valve and the low volume
uses a metering valve.
1. Set temperature control at 300°F / 150°C
MAXIMUM.
2. Open the water bypass ball valve (if so equipped)
on the coil inlet assembly.
TEMPERATURE REGULATING:
Regulate the temperature indicated on the
thermometer to 300°F by adjusting the regulating
valve.
3. Turn the tee on the regulating valve (if so equipped)
clockwise to DECREASE the temperature and
counter clockwise to INCREASE the temperature.
1. Set temperature control at 300°F / 150°C
MAXIMUM.
2. Completely open the water bypass metering valve
(if so equipped) handle turning it counter
clockwise found on the pump or unloader
assembly.
