PRESSURE WASHER OPERATOR’S MANUAL
INSTALLATION
WARNING: Moving this machine on an incline may
cause instability and could result in the machine
tipping over. Equipment damage or bodily harm
could occur.
Place machine in a convenient location providing ample
support, drainage and room for maintenance.
These machines are intended for indoor use. Ma-
chine must be stored indoors when not in use.
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 sources
such as strong winds, freezing temperatures, rain,
etc. Consider accessibility for the replacing of LP
tanks, refilling of detergents, adjustments and
maintenance when selecting a location. Normal
precautions should be taken by the operator to
prevent excess moisture from reaching electrical
components.
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 to come in contact
with machine. Excess moisture reaching the elec-
trical controls will reduce the machine life and may
cause electrical shorts.
3. During installation, beware of poorly ventilated
locations or areas where exhaust fans may cause
an insufficient supply of oxygen. Sufficient combus-
tion 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 in a poorly
ventilated area, outside fresh air may have to be
piped to the burner and a fan installed to bring air
into the room. Avoid small locations or areas 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.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set for elevations of
0 to 2000 ft. Altitudes greater than 2000 ft will require
adjustments to the gas manifold pressures. Consult
your local service dealer/distributor for high altitude
adjustments. In Canada, certification for installation
at altitudes over 4500 feet above sea level is the juris-
diction of local authorities.You should not readjust the
burner ring gas pressure. If you replace your gas valve,
you will need to adjust the new valve. Refer to your
machine’s specification plate for the correct pressure
setting. Follow the installation and adjustment instruc-
tions provided with your replacement valve.
NOTE:Air for combustion and ventilation along with
exhaust flue sizing must conform to methods outlined
in current American Standard (ANSI-Z223.1) National
Fuel Gas Code or National Standard of Canada CSA-
149.1 and CSA-149.2 “Installation Code for Gas Burn-
ing Appliances”.
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter. The VHP2-
15021D requires a 20 amp receptacle to comply with
UL 1776 certification standards.
Venting:
Regulations or ventilation concerns may call for a
chimney or furnace pipe.
When venting, if the machine is to be in an enclosed
area with a chimney on it, be sure the chimney is the
same size as the stack on the machine. Poor draft
will cause machine to soot and not operate efficiently.
When placing for installation, keep in mind that the
pressure washer should be positioned in such a man-
ner that the stack will be as straight as possible and
protrude through the roof of the building at a proper
location and at sufficient height to eliminate downdraft.
The chimney of gas fired machines should be installed
with a down draft diverter.
Draft Diverter:
A draft diverter should be installed above the heating
coil. The diverter serves to sever the chimney effect
created in all sections of furnace pipe positioned below
to enhance the draft through the burner. It also helps
prevent freezing of the coil due to wind chill factors.
NOTE: the draft diverter is not standard on VHP ma-
chines.
When the pressure washer is installed in a tightly closed
room without ventilation openings to the outdoors or
other rooms, provisions shall be made for supplying
air for combustion through special openings, one near
the floor line and the other near the ceiling, each to be
sized on the basis of one square inch or more of free
area for each 1,000 BTU input per hour.

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). On pipe thread connections, use teflon
tape to avoid water leaks. (See Component Identifica-
tion.)
Attach high pressure hose to discharge nipple by pull-
ing the quick coupler collar back and inserting it onto
the discharge nipple. Then push the collar forward to
secure. A detergent injector could be inserted between
the hose coupler and the discharge nipple. (See page
10.)
Place detergent dip tube into liquid soap or detergent
solution. Avoid letting tube suck air.
CAUTION:When installing propane hose to LP tank,
please note that it has left hand threads.
Inspection and Testing:
Before turning gas under pressure into piping, all open-
ings from which gas can escape should be closed.
Immediately after turning on gas, the system should
be checked for leaks.This can be done by watching the
1/2 cubic foot test dial and allowing 5 minutes to show
any movement, or by soaping each pipe connection
and watching for bubbles. If a leak is found, make the
necessary repairs and repeat the above test.
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks, use a soap solution.
After the piping and meter have been checked com-
pletely, purge the system of air. DO NOT bleed the air
inside an enclosed room.
The pressure washer and its individual shut-off valve
must be disconnected from the gas supply piping
system during the pressure testing of that system at
test pressure in excess of 1/2 psig or damage to the
gas valve will occur.
Shut-Off Valve:
A gas shut-off valve has been installed between the gas
supply line and the washer.The plumbing also includes
a union between the shut-off valve and the burner.
Condensation from Coils:
When cold water is being pumped into the water heater
coils, and the burners are on, condensation will form on
the coils and drip down into the burner compartment
giving the appearance of a leaking coil, particularly on
cold humid days.
Check Water Heater Coil for Leaks:
With the burner “OFF” start the pumping machine and
allow to run for a few minutes. Look into the burner
compartment with a drop light or flashlight. If no leak
is visible, then subsequent water dripping from the coil
will be from condensation in the flue gases when the
burner is on, as described in the previous paragraph.

WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could dam-
age the pump. Prepare detergent
solution as required by the manu-
facturer. Fill a container with pres-
sure washer detergent. Place the
filter end of detergent suction tube
into the detergent container.
STEP 2: Apply safety latch to spray gun trigger.
Secure black detergent nozzle into quick coupler.
NOTE: Detergent cannot be applied using the yellow
nozzle.
STEP 3: With the motor
running, pull trigger to oper-
ate machine. Liquid deter-
gent is drawn into the ma-
chine and mixed with water
at an approximate ratio of 15
to 1. Turn pressure control
handle on wand counterclock-
wise. This lowers the pressure by directing the water
flow through the soap nozzle and allow detergent
injector to siphon soap.
Apply detergent to work area. Do not allow detergent
to dry on surface.
IMPORTANT:You must flush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place de-
tergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears
to be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action, spray at a slight angle.
Recommendations:
 • Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
 • If painted surfaces are peeling or chipping,
use extreme caution as pressure washer may
remove the loose paint from the surface.
 • Keepthespraynozzleasafedistancefromthe
surface you plan to clean. High pressure wash
a small area, then check the surface for dam-
age. If no damage is found, continue to pressure
washing.
CAUTION - Never use:
 • Bleach, chlorine products and other corrosive

SHUTTING DOWN AND CLEAN-UP
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C).The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun trig-
ger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until re-
maining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which
does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
the spark plug hole, pull the starter grip several
times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicates the piston is on its compression stroke and
leave it in that position. This closes both the intake
and exhaust valves to prevent rusting of cylinder.
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE: The use of a fuel additive, such
as STA-BIL®, or an equivalent, will minimize the
formulation of fuel deposits during shortage. Such
additives may be added to the gasoline in the fuel
tank of the engine, or to the gasoline in a storage
container.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
possible ice from pressure washer hoses,
spray gun or wand.
Engine Maintenance
During the winter months, rare atmospheric conditions
may develop which will cause an icing condition in the
carburetor. If this develops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by deflecting some of the hot air from the
engine over the carburetor area. NOTE: Refer to the
engine manufacturer's manual for service and mainte-
nance of the engine.
STORAGE
STEP 2: After water has cooled,
turn pump off. Turn main gas valve
off, then close the valve on the LP
tank. Secure the LP tank to the
machine when moving it.
STEP 3: Turn the water off. To pro-
tect from freezing, pull the trigger
on spray gun to allow water to drain
from the system.
STEP 1: Remove detergent suction
tube from container and insert into
one (1) gallon of fresh water. Flush
detergent lines with fresh water,
switch to the pump position and
continue to spray water allowing
burner to cool.
STEP 4: Squeeze trigger on spray
gun to relieve remaining pressure.
Move safety latch into its locked
position.

MAINTENANCE & SERVICE
PREVENTATIVE
MAINTENANCE
1. Check to see that the water pump is properly
lubricated.
2. Follow winterizing instructions to prevent freeze
damage to the pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to be high in mineral content, use
a water softener in your water system or de-scale
as needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Always use high grade quality Landa cleaning
products.
7. Never run pump dry for extended periods
of time.
8. Periodically delime coils as per instructions.
It is advisable, periodically, to visually inspect the
burner. Check air inlet to make sure it is not clogged
or blocked. Wipe off any oil spills and keep this equip-
ment clean and dry.
The areas around the Landa washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves relieve pressure in the line when
the shut-off spray gun is closed. Unloader valves are
preset and tested at the factory before shipping. Oc-
casional adjustment of the unloader may be neces-
sary to maintain correct pressure. (Contact your local
dealer for correct procedure in adjusting unloader
valve.) Tampering with the factory setting may cause
personal injury and/or property damage, and will void
the manufacturer's warranty.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures when-
ever the washer must be stored or operated outdoors
under freezing conditions.
During winter months, when temperatures drop below
32°F, protecting your machine against freezing is nec-
essary. Store the machine in a heated room. If this is not
possible then mix a 50/50 solution of anti-freeze/water
into a 5 gallon bucket and with a short section of garden
hose elevate the bucket and turn the pump on to siphon
the anti-freeze through the machine. If compressed air
is available, an air fitting can be screwed into the inlet
connector and, by injecting compressed air, all water
will be blown out of the system.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event the temperature of the water
should exceed its operating temperature, the high limit
control will turn the burner off until the water cools.
Pumps:
Use only 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 the dipstick found on the
top of the pump or by the red dot visible through the oil
gauge window. Oil should be maintained at that level.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes.This growth is increased by
the extreme heat build up in the coil. The best preven-
tion for liming conditions is to use high quality cleaning
detergents. In areas where alkaline water is an extreme
problem, periodic use of Landa Deliming Powder (part
#9-028008) will remove lime and other deposits before
coil becomes plugged. (See Deliming Instructions for
use of Landa Deliming Powder.)
Deliming Coils:
Periodic flushing of coils is recommended.
1. Fill a container with 4 gallons of water, then add 1
lb. of deliming powder. Mix thoroughly.
2. Remove wand assembly from spray gun and put
spray gun into container. Secure the trigger on the
spray gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated con-
tainer.Turn pump switch on allowing solution to be
pumped through coils back into the container. Solu-
tion should be allowed to circulate 2-4 hours.
4. After circulating solution, flush entire system with
fresh water. Reinstall wand assembly to spray
gun.
Removal of Soot and Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe
and block air flow which will affect burner combustion.
When soot has been detected on visual observation,
the soot on the coil must be washed off after following
the coil removal steps.

LANDA VHP • 8.913-949.0 • Rev. 5/13

PRESSURE WASHER OPERATOR’S MANUAL
MAINTENANCE & SERVICE
1. Remove the tank head assembly by unscrewing
the three Tek screws and lifting the tank head off.
2. Remove the two pipe nipples and associated fit-
tings.
3. Lift the coil out of the outer wrap.
CAUTION:The coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
Pressure Relief Valve:
Each machine is equipped with a relief valve to relieve
pressure in the system when higher than normal oper-
ating pressures are encountered. Unusually high pres-
sures come from an object plugging the spray nozzle.
This problem can easily be remedied by removing the
obstruction. If operating pressure of machine is found
to be normal and relief valve continues to leak, repair
or replace the valve.
Rupture Disk
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst, allowing
high pressure to be discharged through hose to ground.
When disk ruptures, it needs to be replaced.

Propane Cylinder Capacity:
An important consideration with propane systems is the
capacity of the supply cylinder relative to the needs of
the burner. The burner operates on propane as a gas;
as gas is used from the propane cylinder, the liquid in
the cylinder boils to maintain gas pressure.This boiling
process cools the liquid, and in a heavy, continuous-
demand situation, the liquid temperature can fall to
the point at which it cannot provide gas as rapidly as
is needed. In this case, it may be necessary to warm
the propane cylinder by directing a warm spray, not
over 120° F, on the cold cylinder or by manifolding two
propane bottles together to increase total vaporization
capacity. It is recommended that a minimum 30 lb.
vapor propane bottle be used on the machine.
