Install Hose Power Controller Kit
Before you can install the new hose power controller kit,
it must be positioned properly.
1. Position hose power controller in bottom of box fac-
ing up. Ensure it is positioned for easy wire access
on top and left side of controller.
2. Mark through mounting feet for drill holes.
3. Drill through #29 (0.136 in.). Tap 8-32 screw
threads.
Install Fan Power Wires
Install new wires to power fan on hose power controller.
1. Tape the two new wires (plain ends) to a piece of
flexible steel wire. Route wires from the lower com-
partment, through the middle (large) conduit, and to
the upper control box. See F
2. Route, tie wrap, and connect the wires to their
respective terminal blocks.
3. Plug in the wires with push-on connectors into the
fan terminals; terminals do not have polarity.
Wire Hose Power Controller
1. Connect power wire 1252 from top of control box to
terminal #2.
2. Connect black wire 1332 (230V units) or wire N 10
ga.wht (380V units) to terminal #3.
3. Connect the two black transformer primary wires to
terminal #5.
4. Connect the two white transformer primary wires to
terminal #6.
5. Route one of the large 6-gauge transformer second-
ary wires through the D Current Sensor, which is
included in the kit.
6. Connect the black 6-gauge transformer secondary
wires to each red 6-gauge hose power cable with
wire nuts supplied. Secure nuts with electrical tape.

7. Connect D Sensor doughnut wires to terminals #15
and #16. Polarity does not have any affect.
8. Connect blue 5 Vdc signal wires. Connect 3501 to
terminal #7, and 3502 to terminal #8.
9. Ensure all cable connections are secure.
Mount Hose Power Controller and Bracket
Use screws and lockwashers provided in kit to secure
hose power controller to bottom of control box.
Power On and Test
1. Turn power on to unit. Switch the Main Disconnect
to ON and switch the E-Stop to ON.
2. Turn on amber control power switch.
3. Adjust the hose temperature set point (SP1) on con-
trol panel above the actual temperature until the O1
output light on the display stays on constantly.
4. Turn on hose zone control switch (green light).
5. Test newly installed hose power controller.
•
Ensure the green signal light above terminal #4
is on.
•
Ensure the amber current limit light above termi-
nal #5 is on.
•
As the hose reaches temperature, the O1 out-
put light will flicker less until it goes out com-
pletely. As this occurs, the amber light will flicker
off slowly, and then the green light will flicker off
slowly.
If you have a true RMS AC current meter, you can
check one of the hose cables for 45 amps AC +/-
2a. while the O1 output light is steadily on.
•
Check voltage at lower hose circuit breaker
between two hose cables. Keep in mind that
voltage varies with hose length; approximately
15 Vac per 50 ft. of 3/8 in. bundle plus 2.5V for
whip hose.
