4 Installation
Heater tape (field supply)
1 Install heater tape to the outdoor field piping.
2 Provide external power supply for the heater tape.
NOTICE
▪ For the internal heater tape to operate, the power to the
unit MUST be ON. For this reason, during cold periods,
never disconnect the power, nor turn off the main
switch.
▪ In case of a power failure, power to the heater tape
(both internal and external) will be aborted and the
water circuit will NOT be protected. To guarantee a full
protection, it is always possible to add glycol to the
water circuit or to use freeze protection valves, even
when installing heater tape to the outdoor field piping.

To fill the domestic hot water tank

See the installation manual of the domestic hot water tank.
4.3.5

To insulate the water piping

The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.
Outdoor water piping insulation
See the installation manual of the outdoor unit, or the installer
reference guide.
