MAINTENANCE & SERVICE
1. Check to see that water pump is properly
lubricated.
2. Follow winterizing instructions to prevent freeze
damage to 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 on 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 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. Avoid 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. Never allow water to be sprayed on or near 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 burner
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.
Unloader Valves:
Unloader valves are preset and tested at the factory
before shipping. Tampering with the factory setting may
cause personal injury and/or property damage, and will
void the manufacturers 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
and water in the float tank. Turn the engine on to siphon
the anti-freeze mixture through the machine. If com-
pressed 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 tempera-
ture 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 heat-
ing 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 extreme problem, periodic use of Landa Deliming
Powder (Landa Part #8.718-911.0) 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 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 spray gun and
put spray gun into float tank. Secure the trigger on the
spray gun into the open position.
Step 3: Turn 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 spray gun.
