needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Alwa ys use high grade quality cleaning products.
7. Never run pump dry for extended periods of time.
8. Use clean fuel-kerosene, No. 1 fuel oil, or diesel.
Clean or replace fuel filter every 100 hours of operation. A void water contaminated fuel as it will damage
the fuel pump.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature.
10. Nev er allow water to be spray ed on or near the engine
or burner assembly or any electrical component.
11. Periodically delime coils as per instructions.
12. Check to see that engine is properly lubricated.
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 equipment clean and dry .
The flow of combustion and ventilating air to the b urner
must not be blocked or obstructed in any manner.
The area around the Landa washer should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids .
MAINTENANCE AND SERVICE
Unloader V alves:
Unloader valves are preset and tested at the f actory before shipping. Occasional adjustment of the unloader may
be necessary to maintain correct pressure.
Winterizing Procedure:
Damage due to freezing is not covered by w arranty. Adhere to the following cold weather procedures whene ver
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 and
water in the float tank. Turn the engine on to siphon the
anti-freeze mixture through the machine. If compressed
air is available , an air fitting can be screwed into the float
tank by removing the float tank strainer and fitting. Then
inject the compressed air. Water will be blown out of the
machine when the trigger on the spray gun is opened.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a temperature sensitive high limit control switch. In the event that
the water should exceed its operating temperature, the
high limit control will turn the burner off until the water
cools then automatically reset itself. The thermostat sensor is located on the discharge side of the heating coil.
The thermostat control dial is located on the control panel.
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 dipstick found on top of pump,
or 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 heating coil. This growth is increased
by the extreme heat build up in the coil. The best pre ventative for liming conditions is to use high quality cleaning
detergents. In areas where alkaline water is an e xtreme
problem, periodic use of Landa Deliming Powder (C-Tech
Part #9-028008) will remove lime and other deposits
before coil becomes plugged. (See Deliming instructions
for use of Landa Deliming P owder.)
Deliming Coils:
Periodic flushing of coils or optional float tank is recommended.
Step 1 Fill a container with 4 gallons of water, then add
1 lb. of deliming powder . Mix thoroughly. Pour
mixture into float tank.
Step 2 Remove wand assembly from spra y gun and put
spray gun into float tank. Secure the trigger on
the spray gun into the open position.
Step 3 T urn engine on, allowing solution to be pumped
through coils back into the float tank. The solution should be allowed to circulate 2-4 hours or
until the color changes.
Step 4 After circulating solution, flush the entire sys-
tem with fresh water . Clean out float tank and
then reinstall wand assembly to spra y gun.
Removal of Soot and Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may dev elop between the heating coil pipe and
block air flow which will aff ect 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 (See Coil Remov al on page 9).

Rupture Disk:
If pressure from pump or thermal expansion should exceed safe limits, the rupture disk will burst allo wing high
pressure to be discharged through hose to ground. When
disk ruptures it will need to be replaced.
Fuel:
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every 100
hours of operation.
Use No.1 or No 2 Heating Oil (ASTM D306) only. NEVER
use gasoline in your burner fuel tank. Gasoline is more
combustible than fuel oil and could result in a serious explosion. NEVER use crankcase or waste oil in your burner .
Fuel unit malfunction could result from contamination.
Fuel Control System:
This machine utilizes a fuel solenoid valv e located on the
fuel pump to control the flow of fuel to the combustion chamber. The solenoid, which is normally closed, is activated b y
a flow switch when water flo ws through it. When the operator releases the trigger on the spray gun, the flow of water
through the flow switch stops, turning off the electrical current to the fuel solenoid.
The solenoid then closes, shutting off the supply of fuel to
the combustion chamber. Controlling the flow of fuel in this
way gives an instantaneous burn-or-no-burn situation,
thereby eliminating high and low water temperatures and
the combustion smoke normally associated with machines
incorporating a spray gun. 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 the burner is not firing when the spray
gun is in the OFF position.
Fuel Pressure Adjustment:
T o control water temperature , adjust fuel pressure by turning the regulating pressure adjusting screw clockwise to
increase, counterclockwise to decrease. Do not exceed
200 psi. NO TE: When changing fuel pump, a bypass plug
must be installed in return port or fuel pump will not prime.

Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a
clean, solvent saturated cloth, being careful not to plug

the nozzle each season.
Air Adjustment:
Machines are preset and performance tested at the factory - elevation 100'. A one-time initial correction for y our
location will pay off in economy, performance, and extended service life. If a smoky or eye-b urning 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.
Coil Removal:
Removal of coil because of freeze breakage , or to clean
soot from it can be done quickly and easily.
1. Disconnect hose from pump to inlet side of the coil.
2. Carefully disconnect the thermostat sensor making
sure you do not crimp the capillary tube.
3. Remove burner assembly from combustion chamber.
4. Remove the 3-3/8 bolts from each side of coil and
tank assembly (these bolts are used to fasten tank
to chassis).
5. Remove fittings connected to the 1/2" pipe nipples
from inlet and discharge sides of coil.
6. Remove top tank wrap, bend back insulation tabs
and fold back b lanket.
7. Remove bolts that hold down coil to bottom wrap.
8. Remove coil.
9. Replace or repair any insulation found to be torn or
