❑Grip spray gun and wand handle securely.
❑On PHW models, turn the pump and burner switch to
the pump position.
On PHWS models, turn the pump and burner switch
ON and then pull the trigger on the spray gun to acti-
vate a pressure switch which will then start the ma-
chine.
When a steady stream of water flows from the spray
gun and wand, turn the thermostat knob to the 200°
mark, then push the burner switch (PHWS models) or
turn the pump and burner switch (PHW models) to
the burner position. The burner will light automatically
when the spray gun trigger is pulled. On the PHWS
models, the ignition light should be illuminated.
❑Turn the variable pressure control handle clockwise
to increase pressure.
❑Place chemical hose into chemical container and open
chemical valve. NOTE: Do not run this machine more
than five minutes with spray gun closed. When spray
gun is closed more than two minutes, the pump pro-
tector on PHW models will open to allow hot water to
dump on the ground; thus allowing cold water to re-
enter the pump. On PHWS models, a time delay fea-
ture will shut the machine off.
SHUT DOWN PROCEDURES
❑Place chemical line in a bucket of water allowing
chemical to be flushed from system.Then turn chemi-
cal valve off.
❑Push burner switch off or turn switch to pump position
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 (PHW models). On PHWS
models, release the trigger on the spray gun which
will activate a timer to shut the machine off after one
minute. On PHWS models, turn the pump switch off if
the machine is going to be left unattended.
❑Turn water off.
❑Protect from freezing (see Winterizing Procedures).
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.
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
These machines are intended for indoor use.
Machines must be stored indoors when not in use.
❑Location of machine is important. Avoid installing near
combustible material or in poorly ventilated areas.
❑Electrical connection to machine should be the proper
voltage, phase and amperage. See specifications for
particular model. Plug the power cord into a grounded
receptacle. The PHW2-11021D, PHW3-11021D and
PHWS3-11021D 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 inadequate, 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 in-
creases 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 degree 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 maintenance
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 push-
ing the quick coupler collar forward to secure it.
❑Connect the wand, nozzle, hose and spray gun (where
applicable). Use teflon tape on pipe thread connec-
tions to avoid water leaks (see component identifica-
tion).
❑Plug the power cord into the proper power supply. (Re-
fer to serial plate for information.)

PHW/PHWS SERIES PRESSURE WASHER OPERATOR’S MANUAL

In most cases, faster results and better chemical economy
will be obtained by applying the chemical and letting it
“set”for a few minutes, prior to rinsing. This enables 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
chemical or 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 steam valve counterclockwise lightly until you
feel resistance. (Chemical 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.
❑PHWS models have the steam mode built into the
unloader. Just turn the unloader adjustment knob
counterclockwise until you feel resistance.
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 chemicals 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 chemical.
❑Do not allow acidic, caustic or abrasive fluids to be
pumped through the system.
❑Always use high grade quality LANDA cleaning chemi-
cals.
❑Never run pump dry for extended periods of time.
❑Periodically delime coils as per instructions.
❑If machine is operated with smoky or eye-burning ex-
haust, coils will soot up and prevent water from reach-
ing maximum operating temperature. See section 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.
Electrode Setting:
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes
for condition, security and proper spacing. Transformer
test: CAUTION: 10,000 volts -- use defect free insulated
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).

Fuel Control System:
These machines utilize a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combustion
chamber. This solenoid, which is normally closed, is acti-
vated by the unloader's pressure switch. When an opera-
tor releases the trigger on the spray gun, the unloader
goes into a by-pass mode, thus stopping electrical cur-
rent 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 machine 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 by-
pass plug must be installed in return line port or fuel pump
will not prime. (See illustration below.)
Burner Nozzle:
Keep tip free of surface deposits by wiping with clean, sol-
vent-saturated cloth, being careful not to plug or enlarge
nozzle. For maximum efficiency, replace nozzle each sea-
son.
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 extended
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 kerosene or No.1 home
heating fuel is being used. Next, check the air adjustment
on the burner. An oily, smoky fire indicates a lack of air
and the air band should be moved to allow the air to flow
through the burner. Sharp eye-burning fumes indicate too
much air flowing through the combustion chamber. The
air band should be readjusted to allow less air to flow
through the burner.
Cleaning of Coils:
In alkaline water areas lime deposits can accumulate rap-
idly inside the coil pipes. This growth is increased by the
extreme heat buildup in the coil. In areas where alkaline
water is an extreme problem, periodic use of LANDA
Deliming Powder will remove lime and other deposits be-
fore coil becomes plugged. (See Deliming instructions 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 depend-
ing on the flow and pressure of that particular model. Spray
nozzles vary in bore size and angle of spray. Popular spray
angles are 0°, 15°, 25°and 40°. When ordering, please
specify size and angle of nozzle. Nozzle size for each ma-
chine 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 cor-
rect 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 below
32°F, protecting your machine against freezing is neces-
sary. Siphoning a small amount of antifreeze into the sys-
tem is recommended. This is done by pouring a 50/50 mix
of antifreeze and water into the float tank and then si-
phoning 100% antifreeze through the chemical line with
the pump on. If compressed air is available, an air fitting
can be screwed into the float tank strainer fitting 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 deter-
mine which is the problem. This can be done by eliminat-
ing the unloader from the system and attaching the dis-
charge hose directly to the pump. If high pressure is
present, then the unloader needs repairing.
CAUTION: WHEN USING THIS PROCEDURE TO TEST
COMPONENTS, 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 machine,
opens and recycles the cold water back to the inlet side of
the pump. Recycling for longer than five minutes causes
the cold water within the pump to heat up. To avoid dam-
age to the pump, a temperature and pressure relief valve
is installed next to the inlet side of the pump that will open
in the event the water temperature exceeds 140°F. There-
fore, while operating the machine, do not leave the spray
gun closed for an extended period of time.
High Limit Hot Water Thermostat:
For safety, PHW machines are equipped with a high limit
snap switch and PHWS machines are equipped with ad-
justable thermostats. In the event the temperature of the
water should exceed its operating temperature, the high
limit snap switch or adjustable thermostat 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 re-
placement disk to 35 lbs.
AUTO START / STOP
TIMER OPERATION
Once the pump switch is turned on, simply triggering the
spray gun is all it takes to start the machine. Once the
trigger is released the timer will let the machine bypass
water for 15 seconds. It also starts an internal 5 to 60
minute lockout timer. This feature is totally adjustable by
the operator by adjusting the knob at the top of the timer.
We recommend setting the timer for 15 minutes. To reset
the lockout feature, operator must trigger the spray for 10
full seconds.
TROUBLESHOOTING
To by-pass unloader pressure switch, remove wires on C
and NO , jumper same positions on timer.
To by-pass the timer, jumper wires on timer positions C
and 6 together.
