WARNING
• Only a qualified and trained professional should handle the
electrical connections.
• The heat pump power supply circuit must have a reliable ground
connection, and both power supply and external grounding wires
should be eectively connected.
• The trained installer is responsible for testing the circuit and
making the final connections.
PRECONNECTION & REGULATIONS
• When installing the heat pump, electrical work must adhere to
local supply authority regulations and AS3000 standards.
• The heat pump power rating is fixed at 15 amps, so the mains
power supplying the unit should have a minimum 16 amps circuit
breaker installed.
• Please note that this heat pump includes an over-temperature
control cut-out. It is absolutely essential that the water heater
is never operated without this safety device connected to the
circuit. Any resetting or replacement of this device should only be
undertaken by a qualified electrical contractor.
• According to AS/NZS 60335-1 Clause 7.12.2, a disconnection
feature must be incorporated into the fixed wiring, following the
wiring rules.
• Fuse: 260V, 16A.
• Wiring should be carried out by professional installation technicians
following the provided circuit diagram.
• Arrange the layout of power and signal lines neatly, ensuring
they do not interfere with each other or come into contact with
connecting pipes and valve bodies.
• Ensure that the unit's power lines match the specified require-
ments; do not use wires that do not conform to the specifications.
• After completing all wiring construction, carefully inspect it before
switching on the power supply.
• If the supply cord is damaged, it should be replaced by the
manufacturer, a service agent, or a similarly qualified person to
prevent any potential hazards.
