Safety Instructions
7
In the case of particularly hard or impure water, there must
be suitable provision for filtering and treating the water
before it enters the device, in accordance with current
legislation. Failure to do so may result in the HIU becoming
damaged or working incorrectly.
8
Any use of the HIU other than it’s intended use is
prohibited.
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.
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 dripping water 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.
7
The HIU does not contain asbestos or mercury.
8
The HIU should only be used by an authorised adult.
NOTES:
1
Install water hammer arresters to compensate for any
overpressure in the domestic water circuit.
2
In the presence of hot water re-circulation or if a check valve
is fitted into the domestic cold water inlet, suitable devices
must be used to accommodate the expansion of the
medium contained within the system and the heat interface
unit.
3
All hydraulic connections must be visually checked while
pressurising the system. Vibration during transport may
cause the connections to become loose. If a fitting needs to
be tightened apply an appropriate tightening torque,
otherwise the components may become damaged.
