a. When PAC-BH01EHT-E or PAC-BH02EHT-E is installed, connect the base heater power wires to terminals L1 and L2 on the
Relay Box.
When PAC-BH03EHT-E is installed, connect the two base heater power wires that have a white line to terminal L1, and connect
the other two base heater power wires to terminal L2.
Never connect the base heater power wire (L1 or L2) to
of the terminal block on the Relay Box.
Using a wire seal (
D
) and a black cable tie (
C
), water-proof the base heater power wire that was passed through the access hole
for the Relay Box wire.
* If the diameter of the wire, once it has been wrapped in wire seal, is too large to pass through the Relay Box holes, cut back the
wire seal. Leave enough wire seal to keep the Relay Box water proof. (The recommended width of wire seal is 70 mm for the four
base heater power wires.)
Clamp down the base heater power wire at the outlet of the Relay Box with the supplied clamp.
If an active filter is installed, disconnect the earth wire of the active filter from the control box, and screw it down as shown in the
figure below.
