Maintenance And Service
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 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. Place a short section of
garden hose into the bucket and connect it to the
machine. 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 that 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 non-detergent oil. Change oil
after the first 50 hours of use. Thereafter, change the oil
every three months or at 500 hour intervals. Oil level
should be checked by using the dipstick found on top of
the 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 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 Coil Descaler (part
#8.914-296.0) will remove lime and other deposits
before coil becomes plugged.
Periodic descaling of the heating coil is recom-
mended so please consult your local Landa Dealer
for instructions.
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 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 tank. Gasoline is
more combustible than fuel oil and a serious explosion
could result.
NEVER use crankcase or waste oil in your
burner. Fuel unit malfunction could result from contami-
nation.
