Air to Water Heat Pump
How to wire
1. Connect the system interconnection wire to the
terminal as identified with their respective numbers
on the terminal block of the Hydro and outdoor units.
H07 RN-F or 60245 IEC 66 (1.5 mm
2. When connecting the system interconnection wire to
the outdoor unit terminal, prevent water from coming
into the outdoor unit.
3. Insulate the unsheathed cords (conductors) with
electrical insulation tape. Process them so that they
do not touch any electrical or metal parts.
4. For interconnecting wires, do not use a wire joined
to another on the way.
Use wires long enough to cover the entire length.
CAUTION
• An installation fuse must be used for the power supply
line of this air to water heat pump.
• Incorrect / incomplete wiring may lead to an electrical
fire or smoke.
• Prepare a dedicated power supply for the air to water
heat pump.
• This product can be connected to the mains power.
Fixed wire connections:
A switch that disconnects all poles and has a contact
separation of at least 3 mm must be incorporated in
the fixed wiring.
