〈Precautions when connecting the ground〉
When pulling the ground wire out, wire it so that it comes through the cut out section of the cup washer.
(An improper ground connection may prevent a good ground from being achieved.)
9.9.3 Remote Power Supply Wiring, Transmission Wiring, Computerised Control Wire
•

[PRECAUTIONS]
•
Refer to the "Remote Controller Installation Manual" on how to install and lay the wiring for the remote
controller.
•
Do not, under any circumstances, connect the power wiring to the remote controller or transmission

Doing so can destroy the entire system.
•
Connect the remote controller and transmission wiring their respective terminal blocks.
9.9.4 Wiring for the Humidity Regulator (Locally Procured)
<VKM-GAMV1 series only>
•
Pass into the electric parts box together with the power wire through the power wiring through-hole.
•
Remove the short-circuit wires (1 and 2) on the X1M terminal block and connect the wiring for the
humidity regulator.
•
Secure with cramping material together with the power wire. (Refer to Fig. 17-1)

•
If using humidistat, install one per HRV unit.
Controlling more than one HRV unit with a single humidity controller may prevent normal humidity
operation and cause water leakage, etc.

Use the correct screwdriver for tightening the terminal screws. If the blade of screwdriver is too small,
the head of the screw might be damaged, and the screw will not be properly tightened.
If the terminal screws are tightened too hard, screws might be damaged.
