USE AND MAINTENANCE INSTRUC-
TIONS
2.1 GENERAL WARNINGS.
If the device must be deactivated temporarily, act directly on the
main switch to remove voltage from the system and work safely
•
Attention:
using any components that use electrical power
requires some fundamental rules to be observed:
- do not touch the device with wet or moist parts of the body; do
not touch when barefoot.
- if the device is wall-mounted: do not pull the electric cables, do
not leave the device exposed to the elements (rain, sun, etc.);
- the device power cable must not be replaced by the user;
- in the event of damage to the cable, switch the device off and
contact exclusively professionally qualified staff for replacement;
- if the device is not going to be used for a certain period, discon-
nect the main power switch.
2.2 WARNINGS FOR THE USER.
This device does not require any regulation or control by the user.
It is therefore prohibited to open the device front lid.
The only operation that the user must perform is to periodically
check the water pressure of the system in the boiler. The boiler
pressure gauge should read a value between 1 and 1.2 bar.
If the pressure is below 1 bar (with the circuit cool) restore normal
pressure via the filling valve located in the boiler (see boiler instruc-
tion book).
N.B.:
close the valve after the operation.
If pressure values reach around 3 bar, the boiler safety valve may
be activated.
In this case, remove water from an air vent valve of a radiator until
reaching pressure of 1 bar, or ask for assistance from professionally
qualified personnel.
In the event of frequent pressure drops, contact qualified staff for
assistance to eliminate any system leakage.
At the end of its service life the appliance must not be disposed of
like normal household waste nor abandoned in the environment,
but must be removed by a professionally authorised company.
Contact the manufacturer for disposal instructions.
2.3 CLEANING THE CASE.
Use damp cloths and neutral detergent to clean the manifold
casing. Never use abrasive or powder detergents.
