Water Treatment; Electric Connection; Electric Wiring; Power Cable - EAS Electric EBP-06W/1 Owner's Manual And Installation Instructions

5.2 Water treatment

In order to use our appliances under the best conditions, the
following parameters must be respected: free chlorine: max.
2.5 mg/l, total bromine: max. 5.5 mg/l, PH between 6.9 and 8.0.
If chemical or electrophysical disinfection systems are
used, the installer and user must contact the supplier to ensure
they are compatible with our materials. These systems must
be installed after the heating system.

6. ELECTRIC CONNECTION

6.1 Electric wiring

CAUTION
The air source water heater shall have a specialized power
supply, which voltage must in compliance with the rated
voltage.
Power supply circuit of the air source heat pump water heater
with ground wires that must be reliably connected .
Wiring must be performed by professional technicians accord-
ing to the circuit diagram.
Power cable and signal cable shall be laid out orderly and
properly separate power cable from signal cable.
Power cable is attached to this equipment. User could select
power cable by reference to power supply specifications.
Shield wire must be employed for signal wire.
All wiring should be finished, before power is switched on to
the unit, please confirm all connections are correct.
Select the power supply capacity and wire size according to
the Design Manual. The size of the power cable of the unit
should be greater than that of ordinary motors.
Check the subscriber grounding is effective.

6.2 Power cable

To be on safe side, an additional RCCB is necessary to be
installed in the external power supply box. Please refer to
Fig.6-1 to arrange it.
Selecting the wire diameter
3)
Power cable is that the main wire (a) from deconcentrator and
the auxiliary wire (b) leading from deconcentrator and
connected to the power supply device. Please select the wire
diameter by following methods:
The diameter of main wire (a) be conducted by the horsepower
of the water heater and Table 6-1.
The diameter of the wire (b) connected from deconcentrator to
power supply device be conducted by the horsepower of the
water heater and Table 6-1.
