INSTALLATION

Place machine in a convenient location providing ample
support, draining and room for maintenance.

Location:

This machine is certified for indoor installation. Its location
should protect the machine from damaging 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. The unit
should be located considering accessibility of the com­ponents and the refilling of detergents, adjustments
and maintenance. Normal precautions should be taken
by the operator of the unit to prevent excess moisture
from reaching 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 spr ay
from the gun from coming in contact with the machine.
Excess moisture reaching the pressure washer or the
electrical controls will reduce the life of the unit and
may cause electrical shor ts.

3. During installation of the unit, beware of poorly venti­lated locations or areas where exhaust f ans 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 unit in a poorly
ventilated area, outside fresh air may ha v e to be piped
to the burner and a fan installed bringing 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 unit.
Local code will require certain distances from floor

and walls. (Tw o feet away should be adequate.)

AVOID SMALL LOCATIONS OR AREAS NEAR EXHAUST FANS.

Gas Codes:

Confer with local gas company and with proper municipal
officials regarding any specific code or regulations gov­erning the installation. The installation must conform to
local codes.

Electrical:

The unit, when installed, must be electrically grounded in
accordance with local codes. Check for proper po wer sup­ply using a volt meter; check the serial plate for the cor­rect requirements.

Gas Piping:

All piping must comply with local codes and ordinances
of the National Fuel Gas Code. A sediment trap or dri p
leg must be installed in the supply line to the burner.

conver sion burner to house piping.

A manual shut-off valve shall be installed in the gas sup­ply line external to the appliance. See Figure 2. The gas
line should be a separate supply direct from the meter to
the burner. It is recommended that new pipe be used and
located so that a minimum amount of work will be required
in future servicing. The piping should be installed to be
durable, substantial and gas tight. It should be clear and
free from cutting burrs and defects in structure of thread­ing. Cast iron fittings or aluminum tubing should not be
used for the main gas circuit. Joint compounds (pipe dope)
should be used sparingly on male threads only and be
approved for all gases.

Propane Gas:

The following pipe sizes should be used betw een the regu­lator and the gas valve on the bu rner.

Distance From Regulator Pipe Size

0 - 50' 1" 1 PS

Venting:

Because this machine is installed indoors, regulations or
ventilation concerns may call for a chimney or furnace
pipe.

When venting the unit, if the machine is to be in an en­closed area with a stack on it, be sure the flue pipe is the
same size as the stack on the machine. Poor draft will
cause the unit to soot and not operate efficiently. When
placing the unit for installation, keep in mind that the unit
should be positioned in such a manner 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 down draft. The flue pipe of a gas fired unit
should be installed with a down draft diverter.

Input - BTU Per Hour Draft Hood & Flue Pipe Size

250,000 - 320,000 8 inch
320,000 - 410,000 9 inch
410,000 - 600,000 10 inch
600,000 - 750,000 12 inch

Draft Diverter:

The draft diverter should be installed at least one (1) foot
above the heating coil. The dive rter serves to sever the
chimney effect created in all sections of flue pipe posi­tioned below to enhance the draft through the burner. It
also helps prevent freezing of the coil due to wind chill
factors.

Figure 4

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. See Figure 5.

When a room is of unusually tight construction and has a
ventilating fan, which may be used for exhausting air to
outdoors - or has a vented fireplace - it is recommended
that combustion air be supplied to the enclosed room
through intakes extending to the outside of the building
and terminating in downturned fittings, suitably arranged
to prevent obstruction from snow or rain, and including a
protecting screen not smaller than 1/4 inch mesh.

Water Source :

Water source for unit should be supplied by a 5/8” I.D.
garden hose with a city water pressure of not less than 30
psi. If the w ater supply is inadequate, or if the garden hose
is kinked, the unit will run very rough and the burner will
not fire.

Water Connection:

Connect the high pressure hose by pulling the coupler
collar back and then inserting it onto the discharge nipple.
Secure it by pushing the collar forward.

Attach the wand into the trigger gun using teflon tape on
the pipe threads to avoid leaks.

Inspection and Testing Gas Piping:

The building structure should not be weakened by install­ing the gas piping. The piping should not be supported by
other piping, but should be firmly supported with gas hooks ,
straps, bands or hangers. Butt or lap welded pipe should
not be run through or in an air duct.

Before turning gas under pressure into piping, all open­ings 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 necessar y 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 chec ked completely,
purge the system of air. DO NOT bleed the air inside an
enclosed room.

The appliance 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.

Gas Pressure:

The ideal incoming gas pressure is 11" wc (water column)
(minimum 6" wc, maximum 14" wc or 1/2 psig). The cor­rect operating manifold pressure for natural gas is 3.5"
wc. The operating manifold pressure for propane gas is
11" wc. The gas valve pressure regulator can be adjusted
between 3" and 4" wc natural gas or 6" and 11" wc for
propane.

If the desired input rating cannot be obtained within the
above manifold pressure adjusting range, the next size
larger or smaller burner orifice should be used.

WARNING & CHECK LIST

WARNING

1. Installation or servicing of gas appliances and con­trols must only be performed by qualified personnel.
After installation or servicing, test manual valve, op­erating valves, pressure regulation, and automatic
shut-off valve for proper operation.

2. Install in a suitable dry location. The unit must be lo­cated in an area properly protected from the weather.

3. Shut off gas and electricity before starting installation
or service. Turn gas back on to test or operate.

4. DO NOT connect pressure washer before pressure
testing gas piping. Damage to gas valve may result
(6” - 14” W.C.P. or 1/2 psig).

5. DO NOT insert any object other than suitable pipe or
tubing in the inlet or outlet of the gas valve. Inter nal
damage may occur and result in a hazardous condi­tion.

6. DO NOT grip gas valve body with a pipe wrench or
vise. Damage may result causing gas leakage. Use
inlet or outlet bosses or a special body wrench.

7. DO NOT shor t the gas valve terminals.

8. DO NOT allow any flame to impinge on the regulator
vent tubing if supplied. It may clog and cause gas v alve
malfunction.

9. DO NOT use the gas cock to adjust the gas flow.

10. In case main burner fails to shut off , turn off gas supply.

11. Keep all combustible materials away from gas appli­ances. DO NOT allow lint or dust to collect in burner
area.

12. Dials must only be operated by hand. Never use pli­ers, wrenches or other tools to turn dials.

13. Leak test with a soap solution after installation or ser­vice with the main burner on. Coat pipe and tubing
joints, gaskets, etc. Bubbles indicate leaks.

14. If the unit is installed in an enclosed room, care should
be taken to ensure that an adequate supply of air is
available for combustion and ventilation (1 sq. inch
per 1000 BTU).

on. Check for water leaks and tighten as needed.

5. Turn on the main gas supply and tur n the gas valve
control knob into the “ON” position (see page 9).

6. Close the steam knob and chemical valve by turning
clock wise and setting the temperature control knob
between 200° - 225°.

7. Attach the desired high pressure nozzle into the wand
quick coupler by pulling the coupler collar back and
inserting the nozzle. Secure nozzle by pushing the
coupler collar forward.

8. Turn the pump switch on and pull the trigger on the
spray gun to activate the pressure switch which will
then start the machine. When spra y gun is closed more
than one (1) minute, a time delay feature will turn the
machine off.

9. For hot water, push the burner switch to the ON posi­tion and pull the trigger on the spray gun. Sparking
begins, pilot gas ignites and then the ignitor/sensor
will turn the main burner on. Optional remote control
requires the pump switch to be turned ON before the
burner and chemical switches will turn on.

10. To apply detergent, open the chemical va lve counter
clockwise making sure that the chemical pick up tube
is in the chemical solution and not sucking air. On op­tional remotes the chemical switch needs to be turned
to the OFF position then turned to the ON position to
activate the chemical solenoid.

11. To Stop: Turn the burner switch off and place the
chemical pick-up tube into fresh water. Open the
chemical valv e and trigger gun allowing chemical lines
to be flushed and the burner to cool. Otherwise, coil
damage will result.

12. When steam is needed, remove the side panel and
turn the steam knob counterclockwise. Then tur n the
temperature adjustment knob to 275°

13. After water has cooled, turn pump switch to OFF po­sition. If the machine is going to be off f or an e xtended
period of time, put the manual valve on the gas valve
into the OFF position.

14. Tu rn the water off. Protect from freezing.

1. STOP! Read operator’s manual be-
fore oper ating this machine. F ailure
to read operation and warning in­structions may result in personal in­jury or property damage.

2. Turn all switches off.

3. Review installation instructions.

4. Connect water supply hose to the
inlet connector and turn water

PREVENTA TIVE MAINTENANCE

1. Check to see that the water pump is properly lubricated.

2. Follo w winterizing instructions to prevent freeze dam­age to the pump and coils.

3. Always neutralize and flush chemical 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 the 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 equipment 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.

GENERAL OPERATING
TECHNIQUES

If dirt comes off relatively easy and no grease and oil are
present, cleaning with cold water will normally suffice. How­ever , when grease and oil are present, hot water will greatly
speed up the process.

Clean with the spray nozzle a foot or so from the surface
being cleaned. For more difficult cleaning, move the nozzle
in closer.

If the unit is equipped with a shut-off gun and various nozzle
patterns, use the wide patterns for easy soil removal jobs
and the narrow patterns on the more difficult jobs or for
tight areas such as cracks and holes.

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 r insing. This enables the
chemical 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,
howev er , the last operation ma y be application of a chemi­cal or detergent (sanitizing, for example). After such work,
run the unit for 20-30 seconds to clear pump and lines.

MAINTENANCE AND SERVICE

Spray Nozzles

Each unit is equipped with one or more spray nozzles,
depending on model. Diff erent spray nozzles are calibr ated
for each machine depending on the flow and pressure of
that particular model. S pra y nozzles vary in bore size and
angle of spray. Popular spray angles are 0°, 15°, 25°, 40°.
When ordering, please specify size and angle of nozzle.
Nozzle size for each machine is located on the serial plate.

Unloader V alves:

Unloader valves relieve pressure in the line when a shut­off gun is closed. Unloader valves are preset and tested
at the factory before shipping. Occasional adjustment of
the unloader may be necessary to maintain correct pres­sure. (See section in manual on unloaders for correct pro­cedure in adjusting valve.)

Winterizing Procedure:

Damage due to freezing is not covered by wa rranty. Ad­here to the following cold weather procedures whenever
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 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 chemical line with the
pump on. If compressed air is available, an air fitting can
be screwed into the float tank str ainer fitting and by inject­ing compressed air, all water will be blown out of the sys­tem. The use of a draft diverter will prevent the wind chill
factor from freezing the coil.

Pumps:

Use only SAE 30 weight non-detergent oil. Change oil af­ter first 50 hours of use. Thereafter , change oil ev ery three
months or at 500 hour intervals. Oil lev el 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.

HEATING COIL

Condensation from Heating Coil

When cold water is being pumped into the water heater
coil, and the burner is on, condensation will form on the
coil and drip down into the burner compartment, giving
the appearance of a leaking coil, particularly on cold hu­mid days.

To Check Water Heater Coil for Leaks:

With the main burner “OFF” start machine and allow it to
run a few minutes. Check into the burner compar tment
with a drop light or flashlight. If no leaks are visible, then
water dripping from coil is from condensation.

Low Pressure Diagnosis
(Units with shut-off gun)

Refer to the Trouble Shooting Chart for low pressure. If by
referring to the chart, the trouble is found to be either the
unloader or the pump, your next step is to determine
whether, in fact, the unloader or the pump is the problem.
This can be done by eliminating the unloader from the
system and attaching a 50’ charge hose directly to the
pump. If high pressure is developed in this manner the
pump is good, and the unloader needs to be repaired or
replaced. If low pressure is still present the pump needs
repairing. C AUTION : When using this procedure to test
components, keep the shut-off gun open at all times.

High Limit Hot Water Thermostat:

For safety, each unit 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.

➤

GAS VAL VE

REGULAT OR ADJUSTMENT

Deliming Coil:

Periodic coil deliming is recommended.

1. Fill a container with 4 gallons of water, then add 1 lb.
of deliming powder. Mix thoroughly.

2. Remove nozzle from gun assembly and put gun into
container.

VNG/VLP SERIES PRESSURE W ASHER

OPERA T OR’S MANU AL

3. Attach a short section (3-5 ft.) of garden hose to ma­chine to siphon solution from an elevated container or
add mixture to the float tank. Turn pump switch on
allowing solution to be pumped through coil and back
into the container. Solution should be allowed to cir­culate 2-4 hours.

4. After circulating solution flush entire system with fresh
water. Reinstall nozzle in gun.

GAS V ALVE REGULA TOR
ADJUSTMENT

Adjustment of the built-in regulator isn’t normally neces­sary, since it is preset at the factory. Ho w ever, field adjust­ment may be accomplished as follows:

1. Attach manometer at pressure tap port.

2. Remove regulator adjustment screw cap.

3. With a small screwd river, rotate the adjustment screw
clockwise to increase or counterclockwise to decrease
gas pressure.

4. Replace regulator adjustment screw cap (see Figure
6, page 11).

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 preventative f or
liming conditions is to use high quality cleaning chemi­cals. In areas where alkaline water is an extreme prob­lem, periodic use of Landa Deliming Powder will remove
lime and other deposits before coil becomes plugged. (See
Deliming Instructions for use of Landa Deliming Powder.)

Pressure Relief Valve

Each unit is equipped with a relief valve to relieve pres­sure in the system when higher than normally operating
pressures are encountered. If operating pressure of unit
is found to be normal and relief valve continues to leak,
repair or replace the valve. CAUTION: Relief valve can
become obstructed by deposits and must be unscrewed
at least once per year to allow discharge.

PROPANE GAS

General Safety Precautions

Have a qualified gas service person assist in any gas
burner installation or service. Few maintenance people or
mechanics are knowledgeable in gas controls or related
safety practices. Propane Gas is heavier than air; unburned
Propane Gas will gravitate to the floor rather than rise out
of the stack. Hence, adequate floor space and good ven­tilation are especially important with propane systems.

Gas Pressure Requirements

All propane fired units operate on vapor propane fuel only .
They are designed to operate at a pressure of 11” water
column (between 1/3 and 1/2 of one psi), and are often
operated at even higher pressures when extra heat is
needed.

Exterior regulators are needed to control the system. Pro­pane bottles are not included with the unit. A high pres­sure regulator should be installed on the propane bottle
and a low pressure regulator attached to the pressure
washer.

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 vapor gas.
As gas is used from the propane cylinder, the liquid in the
cylinder boils to maintain vapor 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 vapor 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 manif olding two propane bottles
together to increase total vaporization capacity. It is rec­ommended that a minimum 100 lb. vapor propane bottle
be used on the unit, depending on the length of running
time desired.

BURNER FEATURES

Operated Automatic Valve

This machine is equipped with an Intermittent Pilot Igni­tion System. This System is designed to eliminate the need
for a constant burning pilot. Lighting of the pilot is accom­plished through electronic spark ignition each time the
burner and flow switch call for heat. The pilot is not burn­ing when there is no call for heat. Do not attempt to light
the appliance manually as a burn injury or electrical shock
may result. The pilot light will remain on and the main gas
valve is turned off when the spray gun is closed.

Care of Main Burner

Due to condensation from heater coils dripping down on
the burners, a scale build-up may occur in the burner jet
orifices.

1. TO REMOVE BURNER MANIFOLD FROM WATER

HEATER COIL:

Turn off the gas to the main burner by turning the
knob to the “OFF” position on the gas valve and the
main gas supply.

VNG/VLP SERIES PRESSURE W ASHER

Disconnect the pilot and ignition lines from the gas
valve. Disconnect union in main burner line below ther­mostat. (Remove the nuts from the U-bolts, item 44
on page 20 on the VNG-S units.) Slide burner mani­fold out through shell opening.

2. TO CLEAN BURNER JETS:
Select proper size drill for type gas involved. Use pin

vise to hold drill and ream out each jet orifice.
CAUTION: Do not ream out orifices to a larger size.

If the water heater will be exposed to freezing weather, an
anti-freeze solution should be circulated through the coil
by whatever means are available for the particular system
the water heater is used on.

To Adjust Pressure Regulator

Adjustment of the Pressure Regulator is not normally nec­essary since it is preset at the factory. However, field ad­justment may be accomplished as follows:

1. Manometer attachment may be accomplished at the
pressure tap plug.

2. Remove regulator adjustment screw cap (see Figure
6, page 15).

3. With small screwdriver , rotate adjustment screw “cloc k­wise” to increase, or “counterclockwise” to decrease
pressure.

4. Replace regulator adjustment screw.

1. Be sure m ain gas valve (gas cock or selector
arm) is turned on.

2. With gas on and system spar king, probe

terminals PV and TR. If pilot gas does not flow
with 24 volts at these terminals, replace gas
valve.

3. If you do not read 24 volts at t erminals PV and
MV/PV, replace the ignition control unit.

Set test meter to ohm s cale.

1. Disconnect the wire from the IGN terminal on
the ignition control unit.

B. Faulty igni tion control unit 2. Touch one meter probe to the tip of the

ignitor/sensor rod in the pilot. Touch the other
probe to the quick-connect at the other end of
ignitor/sensor wire.

3. If you have continuity from the tip of the ignitor/

PRESSURE EQUIVALENTS

Simply stated, pressure is the force exerted by a gas or liquid attempted to escape from a container. It is useful to know how strong this
“attempt to escape” is. Pressure can be measured with a manometer or with a pressure gauge. At the lower levels, it is expressed in
“inches of water column,” i.e. 11" w.c. Higher pressures are expressed in terms ofthe force exerted against a ssuare inch of area. For
example, 125 lbs. per square inch (125 PSI).

1" Water Column = 50 oz./sq. in. 11" Water Column = 6.35 oz./sq. in.
11" Water Column = 4 lb./sq. in. 1 lb./sq. in. = 27.71" Water Column
1 lb./sq. in. = 2.04" Mercury 1" Mercury = .39 lb./sq. in.
1 Std. Atmosphere = 14.73 lbs./sq. in.
