•
Do not connect the power supply to the unit prior to filling the
space heating circuit (and DHW circuit if it were the case) with
water and checking water pressure and the total absence of any
water leakage.
• Do not connect or adjust any wiring or connections unless the
main power switch is OFF.
• When using more than one power source, check and ensure that
all of them are turned OFF before operating the unit.
• Avoid wiring installation in contact with the refrigerant pipes,
water pipes, edges of plates and electrical components inside
the unit to prevent damage, which may cause electric shock or
short circuit.

•
Use a dedicated power circuit for the unit. Do not use a power circuit
shared with the outdoor unit or any other appliance.
• Make sure that all wiring and protection devices are properly selected,
connected, identified and fixed to the correspond ing terminals of
the unit, specially the protection (earth) and power wiring, taking
into account the applicable national and local regulations. Establish
proper earthing; Incomplete earthing may cause electrical shock.
• Protect the unit against the entry of small animals (like rodents)
which could damage the drain pipe and any internal wire or any other
electrical part, leading to electric shock or short-circuit.
• Keep a distance between each wiring terminal and attach insulation
tape or sleeve as shown in the figure.
