General Requirements
IMPORTANT: This appliance can be used
by children aged from 8 years and above
and persons with reduced physical sensory
or mental capabilities or lack of experience
and knowledge if they have been given
supervisory or instruction concerning use of
the appliance in a safe way and understand
the hazards involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not
be made by children without supervision.
Also:
- water may drip from the discharge pipe
of the pressure-relief device and this pipe
must be left open to the atmosphere; (see
page 10 for details)
- the pressure-relief device is to be operated
regularly to remove lime deposits and to
verify that it is not blocked; (see page 15
for details)
- how hot water can be drained. (see page
15 for more details)
- the type or characteristics of the pressure-
relief device and how to connect it; (see
Fig. 2, page 5 for details and Fig. 5, page
11 for the installation schematic)
- a discharge pipe connected to the
pressure-relief device is to be installed in
a continuously downward direction and in
frost free environment; (see Fig. 4 , page
10 for details)
- details on how to set the temperature
controls for the immersion backup heater
and boiler controls can be found in section
"Commissioning Instructions" (see page
13 for details).
- each circuit must be protected by a
suitable double pole isolating switch with a
contact separation of at least 3 mm in both
poles (see page 12 for details).
- recommended minimum water pressure
0.15 MPa (1.5 bar). Max water pressure
1.6 MPa (16 bar), see page 4 for details.
WARNING: Do not switch on if there is a
possibility that the water in the heater is frozen.
Siting The Unit
The cylinder must be vertically floor mounted. Although
location is not critical, the following points should be
considered:
•
The cylinder should be sited to ensure minimum
dead leg distances, particularly to the point of most
frequent use.
•
Avoid siting where extreme cold temperatures will
be experienced. All exposed pipe work should be
insulated.
•
The discharge pipe work from the safety valves
must have minimum fall of 1:200 from the unit and
terminate in a safe and visible position.
•
Access to associated controls and immersion
heaters must be available for the servicing and
maintenance of the system. Where these controls
are installed against a wall a minimum distance of
250 mm must be left (see Fig. 1, below).
•
Each circuit must be protected by a suitable double
pole isolating switch with a contact separation of at
least 3 mm in both poles.
•
Ensure that the floor area for the cylinder is level
and capable of permanently supporting the weight
when full of water. (see Table 2, Page 7)
•
Please bear in mind the length of the Heat Pump
DHW cable when siting the cylinder.
