Heat pump water heater – SAFETY INFORMATION
58
•
WARNING! It is normal for water to trickle from the pressure safety
device during the heating phase; for this reason, it is necessary to
connect the outlet, which must always be left exposed to the
atmosphere, to a drainage pipe that slopes downwards and towards
an area not subject to frost. It is advisable to also connect the
condensate outlet to the same pipe, through the connection located
on the back side of the water heater.
•
WARNING! The appliance must be drained if left inactive in a room
subject to frost.
When necessary, empty the appliance as follows:
-
Permanently disconnect the appliance form the mains electricity;
-
Close the shut-off valve, if installed, or the central tap of the
domestic water supply network;
-
Open the hot water tap (washbasin or bathtub);
-
Open the tap located on the safety valve.
•
WARNING! Hot water at temperatures above 50°C running from taps
may immediately cause serious burns. Children, the disabled and the
elderly run a greater risk in this regard. Therefore, it is advisable to
use a thermostatic mixing valve connected to the appliance’s water
outlet pipe, which is identified by a red collar.
•
WARNING! If the appliance includes rechargeable batteries, these
must be removed before disposing of the appliance and placed in
specific disposal containers.
Before removing the batteries, the appliance must be disconnected
from the power supply.
