Cleaning of Coils

In alkaline water areas lime deposits can accumulate 

rapidly inside the coil pipes. This growth is increased by 

the extreme heat buildup in the coil. 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.

Spray Nozzles

Each machine is equipped with four spray nozzles. 

Different spray nozzles are calibrated for each machine 

depending on the flow and pressure of that particular 

model. Spray nozzles vary in bore size and angle of 

spray. Popular spray angles are 15°, 25° and 40°. 

When ordering, please specify size and angle of 

nozzle. Nozzle size for each machine is located on the 

serial plate.

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. (Consult your local 

LANDA

 Dealer for the correct procedures.)

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 the 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. Pouring a 50/50 mix 

of antifreeze and water into the float tank and then 

siphon 100% antifreeze through the detergent line with 

the pump on. If compressed air is available, an air 

fitting can be screwed into the float tank strainer fitting 

and, by injecting compressed air, all water will be blown 

out of the system.

Low Pressure Diagnosis

Refer to the low pressure section of the troubleshooting 

guide. If, by referring to the guide, the trouble is found 

to be either the unloader or pump, your next step is to 

determine which is the problem. This can be done by 

eliminating the unloader from the system and attaching 

the discharge hose directly to the pump. If high 

pressure is present, then the unloader needs repairing 

or replacing. 

CAUTION: When using this procedure to test 

components, keep spray gun open at all times.
ATTENTION: Lorsque cette procédure est utilisée 

pour tester les composants, garder le pistolet 

pulvérisateur ouvert en tout temps.
