4 MAINTENANCE

Any maintenance operation must be performed by qualified
personnel only.
When the equipment is working, all the access and operating
doors and covers must be closed and locked.
Unauthorized changes to the system are strictly forbidden.
Prevent conductive dust from accumulating near the louvers
and over them.

).
- Check the condition of the electric pump.
- Check the state of the hose connections.
Every six months, change the cooling liquid and wash out the
hoses and tank with water. Change the liquid in cases, where it
should boil, since it would loose its protective properties.
Failure to carry out the above maintenance will invalidate all
warranties and exempt the manufacturer from all liability.
Routine maintenance must be carried out on the
system according to the manufacturer's instruc-
tions.
Disconnect the power supply before every
operation!
Periodically check the cooling liquid level in the
tank. If the tank is completely empty and/or there
is air in the cooling circuit, this may cause mal-
functions of the pump.
Filling or topping up of the tank with cooling
liquid must be performed with the power source
and WU assembled and positioned on a horizon-
tal surface.
Filling or topping up of the tank must be per-
formed with cooling liquid, code 18.91.001.
