ELECTRIC WIRING

Connection of wiring

� Connect the wires in accordance with the diagram of eachsystem.

� All wiring must be performed by an authorized electrician.

� All field supplied parts and materials and electric works mustconform to local codes.

� Use copper wire only

Connection of wiring

� A main switch or other means of disconnection, having a contactseparation in all poles, must be incorporated in the fixed wiringin accordance with applicable legislation.Do not turn on the main switch until all the wiring is complete.

� A single switch can be used to supply power to units on thesame system. However, branch switches and branch circuitbreakers must be selected carefully.

� Fit the power supply wiring of each unit with a switch and fuse asshown in the drawing.

� Be sure to give the electric grounding (earth) connection.

Precautions

1 Do not connect wires of different gauge to the same powersupply terminal. Looseness in the connection may causeoverheating.

When connecting more than one wire to the power supplywiring, use a 2 mm2 (Ø1.6) gauge wire.

2 Keep total current of crossover wiring between indoor units lessthan 12 A.

When using two power wiring of a gauge greater than 2 mm2

(Ø1.6), branch the line outside the terminal board of the unit inaccordance with electrical equipment standards.The branch must be sheathed so as to provide an equal orgreater degree of insulation as the power supply wiring itself.

3 Do not connect wires of different gauge to the same groundingterminal. Looseness in the connection may deteriorateprotection.

4 Keep the power supply wiring distant from other wires to preventnoise.

5 For remote controller wiring, refer to the "Installation manual ofthe remote controller".

Before obtaining access to terminal devices, all powersupply circuits must be interrupted.

Fresh-up operation

Purposes

When combined with a local ventilating fan (such as the one in toiletand kitchen), the air flow rate of HRV is balanced by either fanoperation or exhaust operation.

However, a circuit with voltage and low current (16 V, 10 mA) isformed between JC and J1, so a relay with low-load contact pointmust be used.

Functions

The unit performs overcharged operation to prevent back flow ofodour.

Necessary parts

Operation contact of exhaust ventilating fan (Field supply)

Example of control wiring

System description

TEST RUN

After completing the installation of the system, check again to makesure that No error was made in wiring or switch setting on the printedcircuit boards of the HRV units.

Then, turn on the power of the HRV units. Refer to the manual of theremote controller of each unit (remote controller for air conditioner,central control unit, etc.) for conducting a trial operation.
