3.2
Preparing the installation site
The cylinder is to be installed vertically on a stable base which must be capable
of supporting the weight when the cylinder is full of water.
The minimum recommended installation space is dependent on the
specification of the cylinder, the slimline variants are recommended if available
space is limited. Additional considerations should be made to allow space to
mount expansion vessels. Full specification, weights and dimensions of the
product range are provided in this booklet.
Access for maintenance of all equipment should be considered when position
the unvented cylinder. Care should be taken that the immersion heater can be
withdrawn for servicing if required, these are 375mm long. Building regulation
G3 should always be followed when installing discharge pipework from the
safety valves.
Any hot outlets which are higher than the cylinder will reduce in pressure by 0.1
bar for every 1m of height difference.
All exposed pipe work should be insulated and additional considerations should
be taken to protect the unit from frost damage. Particular care is needed if the
cylinder is to be installed in an exposed location such as an outhouse or garage.
NOTICE
Make sure water quality complies with EU Directive 98/93 EC.

Electrical
DANGER: RISK OF ELECTROCUTION
•
Turn OFF all power supply before removing the switch box cover,
connecting electrical wiring or touching electrical parts.
•
Disconnect the power supply for more than 1 minute, and
measure the voltage at the terminals of main circuit capacitors or
electrical components before servicing. The voltage MUST be less
than 50 V DC before you can touch electrical components. For
the location of the terminals, see the wiring diagram.
•
Do NOT touch electrical components with wet hands.
•
Do NOT leave the unit unattended when the service cover is
removed.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles provided full
disconnection under overvoltage category III condition, MUST be
installed in the fixed wiring.
WARNING
•
ONLY use copper wires.
•
Make sure the field wiring complies with the applicable
legislation.
•
All field wiring MUST be performed in accordance with the wiring
diagram supplied with the product.
•
NEVER squeeze bundled cables and make sure they do NOT come
in contact with the piping and sharp edges. Make sure no
external pressure is applied to the terminal connections.
•
Make sure to install earth wiring. Do NOT earth the unit to a
utility pipe, surge absorber, or telephone earth. Incomplete earth
may cause electrical shock.
•
Make sure to use a dedicated power circuit. NEVER use a power
supply shared by another appliance.
•
Make sure to install the required fuses or circuit breakers.
•
Make sure to install an earth leakage protector. Failure to do so
may cause electric shock or fire.
•
When installing the earth leakage protector, make sure it is
compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the earth
leakage protector.
NOTICE
Precautions when laying power wiring:
•
Do NOT connect wiring of different thicknesses to the power
terminal block (Slack in the power wiring may cause abnormal
heat.
•
When connecting wiring which is the same thickness, do as
shown in the figure above.
•
For wiring, use the designated power wire and connect firmly,
then secure to prevent outside pressure being exerted on the
terminal board.
•
Use an appropriate screwdriver for tightening the terminal
screws. A screwdriver with a small head will damage the head
and make proper tightening impossible.
•

tightening the terminal screws may break them.
