INSTALLATION
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Location:
The location should protect the machine from damag-
ing environmental conditions, such as wind, rain and
freezing.
1. The machine should be run on a level surface
where it is not readily influenced by outside sourc-
es such as strong winds, freezing temperatures,
rain, etc. The machine should be located consider-
ing accessibility for the replacing of components
and the refilling of detergents, adjustments and
maintenance. Normal precautions should be taken
by the operator of the machine to prevent excess
moisture from reaching electrical controls.
2. It is recommended that a partition be made be-
tween the wash area and the machine to prevent
direct spray from the spray gun from coming in
contact with the machine. Excess moisture will
reduce the machine’s life and may cause electrical
shorts.
3. During installation of the machine, beware of
poorly ventilated locations or areas where exhaust
fans may cause an insufficient supply of oxygen.
Sufficient combustion can only be obtained when
there is a sufficient supply of oxygen available for
the amount of fuel being burned. If it is necessary
to install a machine in a poorly ventilated area, out-
side fresh air may have to be piped to the burner
and a fan installed to bring the air into the area.
4. Do not locate near any combustible material. Keep
all flammable material at least 20 feet away.
Local code will require certain distances from floor
and walls. (Two feet away should be adequate).
WARNING: Avoid small areas or near exhaust
fans.
Gas Codes:
Confer with local gas company and with proper mu-
nicipal officials regarding any specific code or regula-
tions governing the installation. The installation must
conform to local codes.
Electrical:
The machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter; check the
serial plate for the correct requirements.
Gas Piping:
Figure 1: DRIP LEG
Sediment trap (drip leg) must be
installed in the supply line.
Install a union in the gas line adjacent to and upstream
from the control manifold and downstream from the
manual main shut-off valve. A 1/8” NPT plugged
tapping accessible for test gauge connection shall
be installed immediately upstream of the gas supply
connection for the purpose of determining the gas
supply pressure to the burner, and to prevent damage
to gas valve.
If a manual gas shut off valve is not in the gas supply
line within six feet of the machine and in an accessible
location, one shall be installed.
