24. Do not overreach or stand on unstable support.Keep
good footing and balance at all times.
25. Follow the maintenance instructions specified in the
manual.
26. Do not operate this product when fatigued or under
the influence of alcohol or drugs. Keep operating area
clear of all persons.
PRE-OPERATION CHECK
❑Check pump oil level. (Use SAE 30W non-detergent
oil). Dipstick is located on top of pump.
❑Cold water supply (minimum 6 gpm, 5/8", 20 psi)
❑Hose, wand, nozzle (nozzle size per serial plate)
❑Water filter (intact, non restrictive)
❑Open spray gun to relieve pressure before starting.
SET-UP PROCEDURES
Machines must be stored indoors when not in use.
❑Location of machine is important. Avoid installing
near combustible material or in poorly ventilated ar-
eas.
❑Electrical connection to machine should be the
proper voltage, phase and amperage. See specifi-
cations for particular model.Plug the power cord into
a grounded receptacle. The PHW2-11021D and
PHW3-11021D each require a 20 amp receptacle
to comply with UL 1776 standards.
❑Water source for machines 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 inad-
equate, or if the garden hose is kinked, the machine
will run very rough and the burner will not fire.
❑Fill fuel tank with proper fuel.
❑Adding exhaust vent pipe to your oil fired burner is
not recommended because it restricts air flow. This
causes carbon build-up, which affects the operation
and increases maintenance on the coil. If a stack
must be used, refrain from using 90 degree bends. If
the pipe can not go straight up then use only 45 de-
gree bends and go to the next larger size pipe. The
overall pipe length must not exceed 6 feet in length.
OPERATING INSTRUCTIONS
❑Read safety, installation and preventative mainte-
nance instructions before starting machine.
❑Connect the water supply hose to the float tank inlet
swivel connector and turn on water supply.
❑Check fuel tank level.
❑Connect the high pressure hose quick coupler to dis-
charge nipple by sliding the quick coupler collar back
and inserting quick coupler on coupler nipple and
pushing the quick coupler collar forward to secure it.
❑Connect the wand, nozzle, hose and spray gun
(where applicable). Use teflon tape on pipe thread
connections to avoid water leaks (see component
identification).
❑Plug the power cord into the proper power supply.
(Refer to serial plate for information.)
❑Grip spray gun and wand handle securely.
❑Turn the pump and burner switch to the pump posi-
tion.
When a steady stream of water flows from the spray
gun and wand, turn the pump and burner switch to
the burner position. The burner will light automati-
cally when the spray gun trigger is pulled.
❑Turn the variable pressure control handle clockwise
to increase pressure.
❑Place detergent hose into detergent container and
open detergent valve. NOTE: Do not run this ma-
chine more than five minutes with spray gun closed.
When spray gun is closed more than two minutes,
the pump protector may open to allow hot water to
dump on the ground; thus allowing cold water to re-
enter the pump.
SHUT DOWN PROCEDURES
❑Place detergent line in a bucket of water allowing
detergent to be flushed from system. Then turn de-
tergent valve off.
❑Push burner switch off or turn switch to pump posi-
tion and open trigger on spray gun, allowing water
to flow, which will cool down the heating coil.
❑After water has cooled, turn the pump and burner
switch to the OFF position.
❑Turn water off.
❑Protect from freezing (see Winterizing Procedures).

LANDA PHW •9/02
GENERAL WASHING
TECHNIQUES
This machine is equipped with a spray gun and various
nozzle patterns, use the wide patterns on easy soil re-
moval jobs and the narrow patterns on the more difficult
jobs or tight areas such as cracks and holes.
In most cases, faster results and better detergent
economy will be obtained by applying the detergent and
letting it “set”for a few minutes, prior to rinsing. This en-
ables it to do its soil penetrating and loosening work.
Most cleaning work terminates with a high pressure rinse
as part of the normal cleaning procedure. In some cases,
however, the last operation may be the application of a
detergent (sanitizing, for example). After such work, run
machine for 20 - 30 seconds to clear the pump and lines.
Do not run anything through this machine that will dam-
age the steel heating coil and pump.
STEAM COMBINATION
❑Open the pump access panel.
❑Turn the unloader knob counterclockwise lightly un-
til you feel resistance. (Detergent will not siphon when
the steam valve is opened.)
❑Turn the thermostat knob to the 270°mark. (The ther-
mostat is a high limit device and does not regulate
temperature).
❑To stop, reverse steps 1 to 3 and set all controls to
their original settings.
❑Turn burner switch off, open trigger on spray gun
and allow water to cool.
PREVENTATIVE
MAINTENANCE
❑Use clean fuel - kerosene, No. 1 home heating fuel
or diesel. Clean or replace fuel filter every 100 hours
of operation. Avoid water contaminated fuel as it will
seize up the fuel pump. De-soot coils monthly or use
an additive if diesel is being used.
❑Check to see that water pump is properly lubricated.
❑Follow winterizing procedure to prevent freeze dam-
age to pump and coils.
❑Always flush detergents from system after use.
❑If water is known to be high in mineral content, use a
water softener on your water system or use a LANDA
recognized coil cleaning detergent.
❑Do not allow acidic, caustic or abrasive fluids to be
pumped through the system.
❑Always use high grade quality LANDA cleaning de-
tergents.
❑Never run pump dry for extended periods of time.
❑Periodically delime coils as per instructions.
❑If machine is operated with smoky or eye-burning
exhaust, coils will soot up and prevent water from
reaching maximum operating temperature. See sec-
tion on burner adjustments.
MAINTENANCE AND SERVICE
Pump Lubrication:
Use only LANDA SAE 30 weight, non-detergent oil.
Change oil after first 50 hours of use. Thereafter, change
oil every three months or at 500 hour intervals. Oil level
should be checked through use of dipstick found on top
of pump or red dot visible through oil gauge window. Oil
should be maintained at that level.
Fuel:
Use clean (not contaminated with water and debris) kero-
sene, No. 1 home heating fuel or diesel. Drain fuel tank
and replace fuel filter every 100 hours of operation.

Ignition Circuit:
Periodically inspect wires, spring contact and electrodes
for condition, security and proper spacing. Transformer
test: CAUTION: 10,000 volts —use defect free insu-
lated screwdriver and keep fingers off blade! Lay blade
across one contact: OK if arc will span 1/2" between end
of blade and other contact (see illustration).
Transformer Check:
Fuel Control System:
These machines utilize a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combus-
tion chamber.This solenoid, which is normally closed, is
activated by the flow switch. When an operator releases
the trigger on the spray gun, the unloader goes into a
by-pass mode, thus stopping electrical current to the fuel
solenoid coil.With the solenoid closed, the fuel supply to
the combustion chamber ceases. Periodic inspection to
insure that the fuel solenoid valve functions properly is
recommended. This can be done by operating the ma-
chine and checking to see that when the spray gun is in
the off position, the burner is not firing.
Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw clock-
wise to increase, counterclockwise to decrease. Do not
exceed 200 PSI. NOTE: When changing fuel pump, a
bypass plug must be installed in return line port or fuel
pump will not prime.
Burner Nozzle:
Keep tip free of surface deposits by wiping with clean,
solvent-saturated cloth, being careful not to plug or en-
large nozzle. For maximum efficiency, replace nozzle
each season.
Air Adjustment:
Machines are preset and performance tested at the fac-
tory elevation of 100'. A onetime initial correction for your
location will pay off in economy, performance and ex-
tended service life. If a smoky or eye-burning exhaust is
being emitted from the stack, two things should be
checked. First, check the fuel to be certain that kero-
sene or No.1 home heating fuel is being used. Next, check
the air adjustment on the burner. An oily, smoky fire indi-
cates a lack of air and the air band should be moved to
allow the air to flow through the burner. Sharp eye-burn-
ing fumes indicate too much air flowing through the com-
bustion chamber. The air band should be readjusted to
allow less air to flow through the burner.
To adjust, start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings (re-
fer to illustration) and close air shutter until black smoke
appears from burner exhaust vent. Note air band posi-
tion. Next, slowly open the air shutter until white smoke
just starts to appear.Turn air shutter halfway back to the
black smoke position previously noted. Tighten locking
screws.
If the desired position cannot be obtained using only the
air shutter, lock the air shutter in as close a position as
can be obtained, then repeat the above procedure on
the air band setting.
Cleaning of Coils:
In alkaline water areas lime deposits can accumulate
rapidly inside the coil pipes. This growth is increased by
the extreme heat buildup in the coil. In areas where al-
kaline water is an extreme problem, periodic use of
LANDA Deliming Powder will remove lime and other de-
posits before coil becomes plugged. (See Deliming in-
structions for use of LANDA Deliming Powder).
Deliming Coils:
Periodic flushing of coils is recommended.
1. Fill the float tank with 4 gallons of water, then add 1
lb. of deliming powder. Mix thoroughly.
2. Remove nozzle from wand assembly and put spray
gun and wand assembly into float tank. Attach a ny-
lon stocking to the end of the wand to collect debris.
3. Turn pump switch on, allowing solution to be pumped
through coils and back into the float tank. Solution
should be allowed to circulate 2 - 4 hours.

4. After circulating solution, clean and drain float tank
and flush entire system with fresh water. Replace
nozzle in wand.
Spray Nozzles:
Each machine is equipped with one spray nozzle. Differ-
ent spray nozzles are calibrated for each machine de-
pending on the flow and pressure of that particular model.
Spray nozzles vary in bore size and angle of spray. Popu-
lar spray angles are 0°, 15°, 25°and 40°. When order-
ing, please specify size and angle of nozzle. Nozzle size
for each machine is located on the serial plate.
Unloader Valves:
Unloader valves are preset and tested at the factory be-
fore shipping. Occasional adjustment of unloader may
be necessary to maintain correct pressure. (See section
in manual and consult your local LANDA Dealer for the
correct procedures in adjusting the unloader valve.)
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Ad-
here to the following cold weather procedures whenever
the washer must be stored or operated outdoors under
freezing conditions.
During the winter months, when temperatures drop be-
low 32°F, protecting your machine against freezing is
necessary. Siphoning a small amount of antifreeze into
the system is recommended. This is done by pouring a
50/50 mix of antifreeze and water into the float tank and
then siphoning 100% antifreeze through the detergent
line with the pump on. If compressed air is available, an
air fitting can be screwed into the float tank strainer fit-
ting and, by injecting compressed air, all water will be
blown out of the system.
Low Pressure Diagnosis:
Refer to the low pressure section of the troubleshooting
guide. If, by referring to the guide, the trouble is found to
be either the unloader or pump, your next step is to de-
termine which is the problem.This can be done by elimi-
nating the unloader from the system and attaching the
discharge hose directly to the pump. If high pressure is
present, then the unloader needs repairing or replacing.
CAUTION: When using this procedure to test com-
ponents, keep spray gun open at all times.
Coil Removal:
Removal of the coil because of freeze breakage or to
clean soot from it, can be done quickly and easily.
1. Disconnect hose from pump/unloader to inlet side
of coil.
2. Disconnect the electrical connections to the thermo-
stat or remove thermostat sensor.
3. Remove all the fittings from the discharge and inlet
side of the coil.
4. Remove the burner assembly from the combustion
chamber.
5. Remove 3 - 3/8" bolts from either side of coil and
tank assembly (these bolts are used to fasten tank
and handles to chassis).
6. Remove the two 3/8" nuts which are underneath the
bottom wrap (to keep the coil from moving).
7. Remove tank top wrap exposing insulation and coil.
Carefully bend insulation tabs at exhaust stack.
8. Carefully fold back the insulation and remove the
coil.
9. Replace or repair any insulation found to be torn or
broken.
10. Reinstall new or cleaned coil by reversing steps 8
through 1.
Temperature and Pressure Relief Valve:
(Pump Protector)
Machines with spray gun control offer the operator the
convenience of stopping and starting the flow of water at
the end of the discharge hose.When the spray gun stops
the flow of water, the unloader valve, back at the ma-
chine, opens and recycles the cold water back to the
inlet side of the pump. Recycling for longer than five min-
utes causes the cold water within the pump to heat up.
To avoid damage to the pump, a temperature and pres-
sure relief valve is installed next to the inlet side of the
pump that will open in the event the water temperature
exceeds 140°F.Therefore, while operating the machine,
do not leave the spray gun closed for an extended pe-
riod of time.
High Limit Hot Water Thermostat:
For safety, machines are equipped with a high limit snap
switch. If the temperature of the water should exceed its
operating temperature, the high limit snap switch ther-
mostat will turn the burner off until the water cools, then
it will automatically reset itself.
Rupture Disk:
If pressure from pump or thermal expansion should ex-
ceed safe limits, the rupture disk will burst, allowing high
pressure to be discharged through hose to ground.When
the disk ruptures, it will need to be replaced. Torque
replacement disk to 35 lbs.
