Irritrol Junior MAX - Manual (Page 4)

INSTALLATION INSTRUCTIONS - OUTDOOR MODELS:
Remove the lower cover of the Junior Max controller by sliding it down. Place the unit on
the wall using the top keyhole screw slot. Level the controller and then insert screws into
one or more of the three lower screws holes at the cabinet bottom. Drive the screws
through the plastic flashing that keep the cabinet weather resistant. If installing the
controller on drywall or masonry, install screw anchors to prevent the screws from
loosening. Connect the solenoid wires to the terminal block through the 12mm (
1 / 2 ”) hole
in the right side of the cabinet bottom. If the solenoid wires are being installed in conduit,
there is a knock-out on this hole that will accept a 24mm (1”) male conduit adapter.
Connect the wires as shown for the indoor model. Next connect the power wires.
Warning:
AC power wiring must be installed and connected by qualified
personnel only. All electrical components and installation procedures must comply with all
local and national electrical codes. Some codes may require a means of disconnection
from the AC power source installed in the fixed wiring and having a contact separation of
at least 3mm (0.120”) in the line and neutral poles.
Make sure the power is OFF prior to connecting the controller.
The hole on the left side of the cabinet bottom accepts a 12mm ( 1 /
2
”) male conduit adapter.
Route the power and equipment ground wires from the power source, through the conduit
and into the transformer connector compartment. Note: The terminal block accepts wire
size up to 4mm
2 (12 AWG). Remove 10mm ( 3 /
8
”) of insulation from the wire ends.
Using a small flat bladed screwdriver, secure the wires as follows: Line or Line 1 (L1) to
L, Neutral or Line 2 (L2) to N and Equipment Ground to G. Install compartment cover.
Apply power to the controller.
9 VDC Battery. The 9 volt battery compartment is located below the 24VAC terminals.
The 9 volt battery powers the LCD display in the absence of AC power and allows
programming without AC power. Program information is retained during power outages
by an on-board lithium battery.
