Safety Instructions
9
Any coupling of the device with other system components
must be made while taking the operational characteristics of
both units into consideration.
10
An incorrect coupling could compromise the operation of
the device and/or system.
11
If the system is prone to ‘water hammer’ a water hammer
arrester must be installed.
12
If hot water recirculation is present or a non-return valve is
installed in the cold water inlet, provision must be made to
accommodate water expansion by fitting an expansion vessel.
NOTE: Risk of electric shock. Live parts. Shut off the electric
supply before opening the HIU cover.
1
During installation and maintenance operations, always
avoid direct contact with live or potentially hazardous parts.
2
The device must not be exposed to water drops or humidity,
direct sunlight, the elements, heat sources or high intensity
electromagnetic fields.
This device cannot be used in areas at risk of explosion or
fire.
3
The device must be connected to an independent bipolar
switch. If work has to be done on the device, switch off the
electric supply first. Do not use devices with automatic or
time reset, or which may be reset accidentally.
4
Use suitable automatic protection devices in compliance
with current legislation.
5
The device must always be earthed before it is connected to
the electric supply. If the device has to be removed, always
disconnect the earth connection after disconnecting the
electric supply. Check that the earth connection has been
made to the highest of standards under current legislation.
6
Electrical installation must only be carried out by a qualified
technician, in accordance with current requirements.
