7. Use the wiring diagram schematic on the
inside of the control panel cover to
help wire the panel. The incoming power
wires are outlined in green on the wiring
diagram. Attach the incoming hot (black)
lead to the terminal block corresponding to
“L” in the UV control panel. Attach the
common (white) lead to the terminal block
corresponding to “N” in the control panel. The
ground (green) lead is to be attached to the
terminal block corresponding to “GND” in the
control panel.
a. The terminals are spring loaded, insert
a small flat head screw driver into the square
opening of the terminal and use to lever
terminal open (pry away from round opening)
while inserting wire into round opening.
b. Once wire is seated in round opening
release terminal by removing screwdriver
from square opening.
8. OPTIONAL: The Alarm Relay terminals can be
used if desired. Drill a properly sized hole in
the UV control panel enclosure for a correctly
sized conduit to be used with the auxiliary
alarm leads. The conduit should follow the
same rules applied to the incoming power wiring.
Connect one alarm lead to either the normally open
(NO) or normallyclosed (NC) terminal based on the
type of signal required by the alarm panel.
Connect the remaining lead to the common (C)
terminal.
WIRE THE CONTROL PANEL
1. The UV unit operates on 120 VAC
single-phase power. A 15 amp circuit
breaker on the main electrical panel
should be used for the UV disinfection
device. Make sure the breaker is “OFF”
before continuing.
2. Install at least a #14 AWG copper wire
cable from the specified breaker in the
main electrical panel to the UV control
panel.
3. The UV control panel is not equipped
with knockouts for electrical conduit
connections. Drill a properly
sized hole in the UV control
panel enclosure for the chosen conduit.
Ideally the conduit should enter from the
bottom of the enclosure to increase
protection against water infiltration into
the panel.
NOTE:
Flexible conduit is ideal for UV device
4. Attach all conduit and cable connectors
to the control panel. Follow the conduit
manufacturer’s instructions for proper
connection installation.
NOTE:
ONLY
PROPER SIZE
WATERTIGHT
HUB AND FITTINGS CAN BE USED WHEN
ATTACHING CONDUIT AND WIRING TO THE
CONTROL PANEL.
Jet recommends using Carlon or T&B liquidtight
non metallic conduit and fittings for field
installations.
5. Verify all connections are properly
installed and watertight.
6. Pull all cables and wiring through the
conduit and connectors into the control
panel. Allow sufficient wiring to make all
connections in the control panel.
