■ Electrical installation
WARNING
• Ensure electrical circuits are isolated before
commencing the electrical installation.
• The electrical installation must be completed by a
qualified electrician.
• The electrical installation must comply to all Local,
National and International electrical installation
regulations.
• This product must be earthed in accordance with
Local, National and International electrical installation
regulations.
CAUTION
• The Hydro Unit must be connected to a dedicated
power supply for the back up heater circuit.
• The electrical supply must be protected by a suitably
sized over current protection device (fuse, MCB etc)
and an earth leakage protection device.
• The Hydro Unit must be connected to the mains power
supply using a isolating switch which disconnects all
poles and has a contact separation of at least 3 mm.
• The cord clamps, attached to the Hydro Unit, must be
used to secure the electrical cables.
• Wrong connection of electrical cables may result in
electrical component failure or fire.
• Ensure the electrical cables are sized in accordance
with the installation instructions.
• Check that cabling will not be subject to wear,
corrosion, excessive pressure, vibration, sharp edges
or any other adverse environmental effects.
The check shall also take into account the effects
of aging or continual vibration from sources such as
compressor or fans.
• The earth wire should be longer than the power
supply wire from the strain relief clamp. This ensures
that if the cable is pulled out of the terminal block,
the power supply wires are disconnected first.
