INSTALLATION
This machine emits CARBON MONOXIDE, a
DEADLY GAS, and must be vented if used in an
enclosed area. Improper venting can 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. Local codes must
be observed.
1. VENTILATION: Oil fired machines that must
be vented. See the VENTING section of this
manual. Where stacking is not required,
provide adequate ventilations to prevent any
possible accumulation of hazardous fumes.
2. FIRE HAZARD: Keep combustible materials
away from oil machines. DO NOT allow lint or
dust to collect in the burner area.
3. BARRIER: We recommend a barrier be installed
between the machine and wash area to prevent
moisture from coming in direct contact with
electrical controls and engine. This will increase
the machine’s life and lessen electrical
problems.
2. WATER SUPPLY: This machine must have a
water supply meeting or exceeding the
maximum discharge volume specified in the
machine specifications, and a minimum water
inlet pressure of 40PSI / 12.1KGM.
7. WATER CONDITIONS: Local water conditions
affect the coil adversely more than any other
element. In areas where troublesome conditions
may exist with like equipment (such as water
heaters), we recommend the use of a water
softener.
8. FREEZING: This machine must be protected
from freezing according to STORAGE section
of MACHINE MAINTENANCE.
9. 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 oil can cause
delayed ignition, poor spray patterns, and
rumbling fires. As moisture will quickly destroy
fuel pumps, make certain that tank openings
are secure and moisture cannot enter. In cold
weather areas, frost build up will occur in fuel
tanks. As the weather warms it turns to
condensate, and the water will be in the tank.
Keep the tank clear 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.
10. CHEMICALS: Mix chemicals per the chemical
manufacturers printed directions. Follow all
mixing, handling, application, and disposal
instructions. Wear gloves, boots, goggles, and
protective clothing appropriate for the chemical
being used
VENTING
DANGER: This machine emits carbon monoxide,
and deadly gas, and MUST NOT be used in an
enclosed or confined area.
DANGER: Engine exhaust gases contain
poisonous carbon monoxide. Carbon monoxide is
oderless, colorless, and can cause death if inhaled.
Avoid inhaling gas fumes. Engine MUST NOT be
used in an enclosed or confined area.
