24. Install the machine 18” above the floor and about 2
feet from wall providing adequate ventilation and
space.
25. When making repairs disconnect from electrical
source and shut off gas valve.
26. Install this machine on non combustible flooring.
Caution: Only qualified persons should fill your LP-Gas containers.
1. Never allow your LP-gas container to be filled above the maximum safe level as indicated by a scale or the
fixed liquid level gauge (outage). Do not use the visible gauge for filling.
2. Do not use a wrench or pliers to close the service valve or fixed liquid level gauge . T hese valve s are desig ned
to be closed leak-tight by hand or screwdriver as appropriate. If wrenches are necessary to stop a leak, the
valve needs repair or replacement.
3. When tightening the POL Nut (left hand thread) on the service valve, draw it up snug with a proper wrench.
This is a machined male brass fitting which seats securely against a female seat in the POL valve – no pipe
dope is necessary. Acme/Type 1 valves have right handed threads which are secure when hand tight, and on
the Quick Disconnect/Type 2 Valves, the male connection is inserted into the female connection on the cylinder
valve. (No wrenches required for both the Acme and the Quick Disconnect.)
4. When using container, slowly open service valve all the way. Listen to the regulator. A continuous hiss may
indicate a leak or an open valve on an appliance.
5. Check all tank and the line connections periodically to be sure they are tight. When testing for leaks, use
approved leak detector solution – not matches.
6. Make certain your container is properly fastened in place.
7. Turn container with open part of contain e r guar d to war d s fra me. Th is pr ot ects valves and regulator against
flying rocks and mud. Transport container in the proper position in which it is used, with the valves closed and
POL Plugs inserted for POL Valves or Dust Caps for Acme Valves. Secure the tank against falling or rolling.
8. Check for leaks after connecting. Apply approved leak detector solution to connection, turn off all burners and
pilots, and open service valve. Leaks will be detected by the growth of the bubbles. If bubbles grow, tighten or
repair the connection as needed. Repeat leak test until problem is corrected.
9. LP-gas is normally non-corrosive – you need not worr y about the inside of your container. However, the outside
should be kept free from rust by a periodic coat of paint in a light reflective color. It is very important to inspect
and maintain the bottom and foot ring on the container.
10. Do not store LP-gas containers indoors or in enclosed areas. Do not expose LP-gas container to heat. Always
store with service valve closed and plugged as required.
11. Do not attempt to repair any containers, container valves, regulator or appliances by yourself. Use only trained
certified LP-gas service personnel to perform repairs.
Propane tanks, gas bottles will not be picked up by local garbage collectors. Improper propane tank
disposal might be illegal in some areas. Propane tank disposa l is a safety issu e that is e asily handled by a
propane company.
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.
Machine must be stored indoors when not in use.
Location
The 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. 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
between the wash area and the machine to
prevent direct spray from the spray gun to come in
contact with machine. Excess moisture reaching
the electrical controls will reduce the machine life
and may cause electrical shorts.
3. During installation, beware of poorly ventilated
locations or areas where exhaust fans ma y cau se
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 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
municipal officials regarding any specific code or regulations governing the installation. The installation must
conform to local codes.
Consult your local service dealer for high altitude
adjustments. In Canada, certification for installation at
altitudes over 4500 feet above sea level is the jurisdiction of local authorities. You should not readjust the
burner ring gas pressure. If you replace your g as 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 instructions 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
Burning 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 VHP215021D 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 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
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 heat ing
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
machines.
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.
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 Identification.)
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any for m to locate
gas leaks, use a soap solution.
After the piping and meter have been checked
completely, 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.
Attach high pressure hose to discharge nipple by
pulling 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 discha r ge nipp le .
(Assembly Instructions)
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
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
necessary repairs and repeat the above test.
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.

and General Cleaning Techniques
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, 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 damage
the pump. Prepare detergent
solution as required by the manufacturer. Fill a container with pressure
washer detergent. Place the filter
end of detergent suction tube into
the detergent container.
STEP 2: Apply safety latch to spray gun trigger.
NOTE: Detergent cannot be applied using the yellow
nozzle.
STEP 3: With the motor
running, pull trigger to operate
machine. Liquid detergent is
drawn into the machine and
mixed with water at an approximate ratio of 15 to 1. Turn
pressure control handle on
wand counterclockwise. This
lowers the pressure by directing the water flow th rough
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
detergent 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 bo ttom 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
damage. If no damage is found, continue to
pressure washing.
CAUTION - Never use:
•Bleach, chlorine products and othe r co rro siv e
chemicals
These chemicals will harm the machine and will
damage the surface being cleaned.
Rinsing
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle.
NOTE: You can also stop detergent from flowing by
simply removing detergent siphon tube from bottle.
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.
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
protect from freezing, pull the
trigger on spray gun to allow water
to drain from the system
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
trigger to release pressure.
2.
Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until
remaining 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
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.

, or an equivalent, will minimize
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 maintenance of the engine.
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 perio ds
of time.
8. Periodically de-lime 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.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
possible ice from pressure washer hoses,
spray gun or wand.
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. Occasional adjustment of the unloader may be necessary 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
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. 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.
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 prevention for liming conditions is to use high quality cleaning
detergents. In areas where alkaline water is an extreme
problem, periodic use of Landa Coil Descaler (part
#8.914-296.0) will remove lime and other deposits
before coil becomes plugged.
Periodic descaling of the heating coil is recommended so please consult your local Landa Dealer
for instructions.
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.
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
fittings.
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.
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 10W-40 weight non-foaming oil. Change
oil after first 50 hours of use. Thereafter, change oil
every year 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.
Each machine is equipped with a relief valve to relieve
pressure in the system when higher than normal
operating pressures are encountered. Unusually high
pressures 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, continuousdemand 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.

generen insuficiente suministro de oxígeno. Se
puede obtener una buena combustión, solamente
cuando hay suficiente suministro de oxígeno
disponible para la cantidad de combustible incinerado. Si se instala en una área con ventilación
insuficiente, suministrar aire fresco exterior al
quemador con un ventilador instalado dentro del
ambiente. Evitar espacios estrechos o áreas cerca
de ventiladores.
Regulaciones Sobre Gases:
Consultar con la compañía de gas local y con las autoridades municipales respecto a las normas o regulaciones específicas que rijan el montaje. El montaje
debe hacerse de acuerdo con las regulaciones municipales locales.
Aspecto Eléctrico:
El voltímetro VHP2-15021D requiere un receptáculo de
20 amp para cumplir con los estándares de certificación UL 1776.
Respiradero:
Cuando la lavadora a presión es instalada en un
espacio muy estrecho sin aberturas de ventilación al
exterior, deben tomarse medidas para suministrar aire
de combustión a través de aberturas especiales, una
cerca del piso y otra cerca del techo; cada una medida
en base a una pulgada cuadrada o más de área libre
por cada 1,000 BTU de consumo por hora.
Colocación:
No colocar la máquina cerca de materiales combustibles. Mantener todo material inflamable a 20 pies de
distancia por lo menos.
Permitir suficiente espacio para dar servicio de
mantenimiento a la unidad.
Regulaciones municipales locales requieren mantener
ciertas distancias entre el piso y las paredes.
(Dos pies de distancia deberían ser suficientes.)
Suministro de Agua:
El suministro de agua para la unidad deberá ser
provisto por una manguera de jardin de 5/8” de
diámetro interno con una presión de agua local no
menor a 30 psi. Si el suministro de agua es insuficien te,
o si la manguera está torcida, la unidad funcionará mal
y el quemador no arrancará.

ADVERTENCIA
líquido, por favor, notar que las roscas
están hacia la izquierda.
Inspección y Prueba:
Antes de mantener el gas a presión en las tuberías,
cerrar todas la aberturas por donde pueda escapar el
gas. Inmediatamente después de encender el gas,
debe revisarse el sistema en busca de fugas. Esto
puede hacerse observando el indicador de prueba de
½ pie cúbico y esperando 5 minutos para observar
cualquier movimiento, o aplicando una solución de
jabón a cada conexión de la tubería y observando las
burbujas. Si se detectan fugas, hacer las reparaciones
necesarias y repetir la prueba anterior.
Las tuberías y accesorios defectuosos deben ser
cambiados, no deben ser reparados. Nunca usar
ningún tipo de llama o fuego para localizar fugas de
gas, usar una solución de jabón.
Luego que la tubería y el medidor han sido revisados
completamente, purgar el aire del sistema. NO purgar
el aire dentro de un ambiente cerrado.
La lavadora a presión y la válvula individual de cierre
deben ser desconectados del sistema de tuberías de
suministro de gas durante la prueba de presión donde
una presión sobre ½ psig podría dañar la válvula de
gas.
Válvula de Cierre:
Se ha instalado una válvula de cierre entre la línea de
suministro de gas y la lavadora. La instalación también
incluye una unión entre la válvula de cierre y el
quemador.
Condensación en los Serpentines:
Cuando se bombea agua fría por los serpentines del
calentador y los quemadores están encendidos, se
producirá condensación sobre los serpentines y
goteará al compartimiento del quemador dando la
impresión de fugas en los serpentines, particularmente
en días húmedos y fríos.
Revisar el Serpentín del Calentador de
Agua en busca de Fugas:
Con el quemador “APAGADO” arrancar la unidad de
bombeo y dejar que funcione por unos minutos.
Observar el compartimiento del quemador con una
lámpara o una linterna de mano. Si no se observa
ninguna fuga, el goteo de agua del serpentín será
producto de la condensación de gases combustibles
cuando el quemador está encendido, como se ha
descrito en el párrafo anterior.

Mantenimiento Y Servicio
Mantenimiento Preventivo
1. Revisar si la bomba de agua está lubricada apropiadamente.
2. Seguir las instrucciones para acondic ion a mie n to
de invierno y prevenir daños por congelamiento de
la bomba y los serpentines.
3. Siempre neutralizar y limpiar después de usar
productos detergentes en el sistema.
4. Si el agua tiene alto contenido de minerales, usar
un ablandador de agua o eliminador de escamas
en el sistema, según sea necesario.
5. No permitir que líquidos ácidos, caústicos o
abrasivos sean bombeados a través del sistema.
6. Siempre usar productos de limpieza de alta calidad
Landa.
7. Nunca hacer funcionar la bomba en seco por
extensos períodos de tiempo.
8. Periódicamente, limpiar los depósitos de cal de los
serpentines según las instrucciones.
Se aconseja inspeccionar regularmente, el quemador
en forma visual. Revisar el ingreso de aire para
asegurar que no esté atascado o bloqueado. Limpiar
todos los derrames de aceite y mantener la máquina
limpia y seca.
Las áreas alrededor de la lavadora Landa deberán
mantenerse limpias y libres de materiales combustibles, gasolina y otros líquidos inflamables.
Procedimiento de Acondicionamiento para
el Invierno:
El daño debido al congelamiento no está cubierto por la
garantía. Respetar los siguientes procedimientos para
el clima frío siempre que la lavadora deba almacenarse
u operarse a la intemperie bajo condiciones de congelamiento.
Durante los meses de invierno, cuando la temperatura
baja a menos de 32° F, se debe proteger la máquina
del congelamiento según sea necesario. Almacenar la
máquina en un ambiente con calefacción. Si ésto no es
posible, mezclar una solución 50/50 de anticongelante/
agua en un depósito de 5 galones. Colocar una sección
corta de manguera de jardin en el d epósito y conectar a
la máquina. Elevar el depósito y prender la bomba para
sifonear el anticongelante a la máquina. Si se dispone
de aire comprimido, puede instalarse un accesorio de
aire al conector de entrada y todo el agua será
evacuada fuera del sistema.
Termostato de Control de Agua Caliente:
Para seguridad, cada unidad está equipada con un
interruptor de control de temperatura. Si la temperatu ra
del agua excede la temperatura de operación, el
control apagará el quemador hasta qu e el ag u a se
enfríe.
Bombas:
Usar solamente aceite no-detergente SAE 10W-40.
Cambiar el aceite después de las primeras 50 horas de
uso. Luego, cambiar el aceite cada tres meses o en
intervalos de 500 horas. El nivel de aceite debe ser
revisado usando la varilla de medir ubicada en la
bomba o el punto rojo visible a través de la ventana del
calibrador. El aceite debe mantenerse en ése nivel.
El flujo de combustión y aire de ventilación al
quemador no deben ser obstruídos o bloqueados de
ninguna manera.
Mantenimiento Y Servicio
Válvulas de Descarga:
Las válvulas de descarga liberan la presión en la línea
cuando la pistola de rociado está cerrada. La válvulas
de descarga son programadas y verificadas antes de
salir de fábrica. Ocasionalmente, deben regularse para
mantener la presión correcta. (Ver la sección del
manual sobre válvulas de descarga para el procedimiento correcto de regulación de la válvula.)
En áreas de agua alcalina, los depósitos de cal pueden
acumularse en los serpentines rápidamente. Estos
depósitos se incrementarán con la alta temperatura
generada en los serpentines. La mejor prevención para
la sedimentación es usar productos de limpieza de alta
calidad. En áreas donde el agua alcalina es un
problema, el uso regular de Polvo eliminador de cal
Landa (parte #9-028008) limpiará la cal y otros sedimentos antes que obstruyan el serpentín.

Page 46
Mantenimiento
Eliminador de cal de Serpentines:
Se recomienda un lavado periódico de los serpentines.
1. Llenar un depósito con 4 galones de agua y luego
añadir 1 libra de polvo desincrustante. Mezclar
completamente.
2. Retirar la varilla de la pistola y colocar la pistola en
un depósito. Asegurar que el gatillo de la pistola
esté en posición abierta.
3. Unir una sección corta (3-5 pies) de manguera de
jardin a la máquina para sifonear la solución hacia
un depósito elevado. Encender la bomba para que
la solución sea bombeada a través de los serpentines de regreso al depósito. La solución deberá
circular por 2-4 horas.
4. Después de hacer circular la solución, lavar todo el
sistema con agua fresca. Reinstalar la varilla en la
pistola.
Remoción de Hollín del Serpentín de
Calentamiento:
Durante el proceso de calentamiento pueden producirse residuos de combustible en forma de ho llín en tr e
los serpentines de calentamiento, bloquear el flujo de
aire y afectar la combustión del quemador. Cuando se
observe hollín, debe limpiarse después de seguir los
pasos para desmontar el serpentín.
Capacidad del Cilindro de Gas Propano:
Una importante consideración con los sistemas de gas
propano, es la capacidad del cilindro de suministro en
relación a las necesidades del quemador. El quemador
opera con gas propano del cilindro, el líquido del
cilindro ebulle para mantener la presión del gas. Este
proceso de ebullición enfría el líquido y, en una
situación de demanda continua y exigente, la temperatura del líquido puede disminuir a un punto que no
puede suministrar gas tan rápido como se r equiere. En
este caso, podría ser necesario calentar el Cilindro de
Gas Propano rociando agua caliente que no exceda
120° F, sobre el cilindro frío o al colocar dos botellas de
gas propano juntas para incrementar la capacida d total
de vaporización. Se recomienda usar una botella de
gas propano de 30 libras de capacidad en la unidad.
1. Retirar el ensamble del tanque destornillando los
tres tornillos Tek y levantando el cabezal del
tanque.
2. Retirar los dos niples de la tubería y los accesorios
correspondientes.
3. Levantar el serpentín fuera de la envoltura exterior.
PRECAUCION: El serpentín pesa casi 80 libras.
Usar técnicas de levantamiento apropiadas.
4. Limpiar, reparar y reemplazar el serp en tín
siguiendo los pasos anteriores pero a la inversa.
Válvula de Alivio de Presión:
Cada unidad está equipada con una válvula de alivio
de presión para descargar la presión del sistema
cuando se detectan presiones de operación más altas
de lo normal. Las altas presiones inusitadas provienen
de algún objeto que obstruye la boquilla de rociado.
Este problema se puede remediar fácilmente al retirar
la obstrucción. Si la presión de operación de la unidad
es normal y la válvula de alivio sigue con fugas, reparar
o reemplazar la válvula.
ADVERTENCIA: Algunos productos detergentes
pueden ser dañinos cuando se los inhala o ingiere,
causar náuseas, desmayo o envenenamiento
agudo. Los elementos dañinos pueden causar
daño a la propiedad o lesiones graves.
El conjunto de inyectores para productos detergentes
de Landa se puede utilizar para hacer sifón y mezclar
los detergentes.
1. Apague el motor y cierre la entrada de agua.
Antes de acoplar el inyector de productos detergentes, abra la pistola de rociado para aliviar la
presión.
2. Para acoplar el inyector de productos detergentes
entre la unidad de lavado a presión y la mangue ra
de alta presión, tire del cuello del acoplador de
conexión rápida del inyector hacia atrás y coloque
el manguito de unión de descarga. La flecha de la
válvula de inyección debe apuntar en la dirección
del flujo.
3. Conecte la manguera de descarga de presión al
manguito de unión de inyección con el acoplador
de conexión rápida. Empuje el cuello del acoplador
hacia el manguito de unión.
NOTA: El inyector para los productos detergentes no
puede hacer sifón cuando la manija de control, de la
extensión de presión variable, se encuentra en
posición de alta presión.
4. Haga arrancar la unidad tal como se describe en
las Instrucciones para operar la unidad.
5. Coloque el tubo de aspiración para el producto
detergente en el recipiente de la solución detergente.
6. Instale la boquilla para detergente en el acople
rápido.
7. Abra la pistola a gatillo. La proporción de agua y
del producto detergente es de aproximadamente
15 a 1.
8. Para limpiar, coloque el tubo para el producto
detergente en un recipiente con agua limpia y siga
los pasos 5 y 7 para evitar que los depósitos detergentes dañen el inyector.
9. Si la unidad cuenta con una extensión de presión
variable; para limpiar, alivie la presión haciendo
girar la manija para el control de presión en sentido
contrario a las agujas del reloj. Esto dirige el flujo
de agua a través de la boquilla de jabón y permite
que el inyector del producto detergente succione el
jabón. Para enjuagar con agua a alta presión,
simplemente gire la manija de control en la
dirección de las agujas del reloj.
