HOT SERIES PRESSURE WASHER
OPERATOR’S MANUAL
7
LANDA HOT • 96-626 • REV. 2/04
It is recommended that a partition be made between
the wash area and the machine to prevent direct water
spray from coming in contact with the machine. Excess
moisture reaching any electrical components or controls
will reduce machine life and may cause electrical shorts.
During installation of the machine, beware of poorly ven-
tilated 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 bringing the air into the machine.
WARNING: Avoid small areas or areas near exhaust
fans.
Electrical
The machine, when installed, must be electrically
grounded in accordance to local codes. Check for proper
power supply using a volt meter. The HOT2-1100,
HOT2-1500, and HOT3-1100 each require a 20 amp re-
ceptacle to comply to the UL 1776 Standard.
Placement
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.)
Water Source
Water source for machine should be supplied by a
5/8" I.D. garden hose with a city water pressure of not
less than 30 psi. If the water supply is inadequate, or if
the garden hose is kinked, the machine will run very rough
and the burner will not fire.
Connection
Connect the wand, nozzle, hose and spray gun, where
applicable (see Component Identification). On pipe thread
connections, use teflon tape to avoid water leaks.
Venting
Adding exhaust vent pipe to your oil fired burner is not
recommended. The pipe restricts air flow which causes
carbon buildup, which affects the operation, and in-
creases maintenance on the coil. If a stack must be used,
refrain from using 90° bends. If the pipe cannot go straight
up then use only 45° bends and go to the next larger size
pipe. The overall pipe length must not exceed 6 feet.
STARTING AND OPERATING
INSTRUCTIONS
To Start
1. STOP! Read operator’s manual before operating this
machine. Failure to read operation and warning in-
structions may result in personal injury or property
damage.
2. Connect water supply hose to inlet connector and
turn water on.
3. Check fuel tank and pump oil levels.
4. Connect high pressure hose to discharge nipple by
sliding quick coupler collar back. (If detergent is to
be applied, insert a detergent injector.)
5. Insert quick coupler onto discharge nipple and se-
cure by pushing quick coupler collar forward.
6. Securely attach the desired high pressure nozzle into
wand coupler as described in steps 4 and 5.
7. Connect the power cord into the proper electrical
outlet, then push in the GFCI reset button. (Refer to
serial plate for information.)
8. Grip spray gun variable pressure wand securely. Then
turn the variable pressure control handle counter-
clockwise.
9. Turn switch to pump position. When a steady stream
of water flows from the spray gun and wand, the ma-
chine is ready for cold water cleaning by turning the
variable pressure control handle clockwise to raise
the pressure.
10. For hot water washing, turn the switch to the burner
position. (The burner will light automatically.)
NOTE: The optional float tank siphons detergent through
the pump when the detergent pick-up tube is placed into
a bucket of detergent and the detergent valve, located
on the control panel, is opened.
To Stop
1. If using the detergent injector, place detergent line
in a bucket of water allowing detergent to be flushed
from system (see “How To Use The Detergent Injec-
tor”).
2. Turn switch to pump position and continue spraying
water allowing the water to cool.
3. After water has cooled to less than 100°F, turn switch
to the off position.
4. Turn water off. Open the spray gun to relieve remain-
ing pressure.
5. Protect from freezing.
