HNG SERIES PRESSURE WASHER
OPERATOR’S MANUAL
machine should be located considering accessibil-
ity for the replacing of components and the refilling
of detergents, adjustments and maintenance. Nor-
mal precautions should be taken by the operator of
the machine to prevent excess moisture from reach-
ing the power unit or electrical controls.
2. It is recommended that a partition be made between
the wash area and the machine to prevent direct
spray from the spray gun from coming in contact with
the machine. Excess moisture reaching the power
unit or electrical controls 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, outside 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.
Allow enough space for servicing the machine.
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 munici-
pal officials regarding any specific code or regulations
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:

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 loca-
tion, one shall be installed.
