4.3 ELECTRICAL INSTALLATION

ATTENTION!

• Before beginning repair or modication of

the HRV unit, make sure the main power

switch is off!

• The wiring must be done by a person authorized

to perform electrical installations. It is neces-

sary to follow all instructions in this manual and

to comply with local laws and regulations.

• Before connecting the wiring, make sure that

terminal indications match the diagram. If in

doubt, do not connect the unit, and contact the

supplier!

• The unit must be connected to the mains using

a heat-protected, insulated cable with a cross-

section that meets local regulations.

• To maintain electrical protection, all cables must

t in the hole on the sides of the control unit

casing (1/2" ex-conduit connector).

• Any changes or modications to the internal

wiring of the unit are prohibited and will void

the warranty!

• The unit’s correct operation can be guaranteed

only if original accessories are used.

• If it is necessary to install a sensor or control

component in the unit or on its casing, consult

beforehand with the unit manufacturer or rep-

resentative.

4.3.1 SUPPLY WIRING

Adjacent to the main power switch is a 7/8" hole

through the regulator box and a pre-installed 1/2"

ex-conduit connector. If the electrical installer

decides, the pre-installed connector can be re-

moved and supplanted with an appropriate tting

rated for:

• The listed Maximum Overcurrent Protection of

the device.

• The listed voltage of the device.

• 3 10AWG insulated wires: Line 1,

Line 2 (Neutral), and Protective Earth Ground.

• Compliance with local laws and regulations.
