INSTALLATION OF OPTIONAL 80% TANK
CAPACITY SENSING COMPONENTS (KIT:KT5001)
18
Note: PROMAX also offers the model, RG5410A-KT,
with the 80% Capacity Shut Off Kit installed at the
factory.
Ꮨ
Warning: Prior to performing any type of mainte-
nance work on your RG5410A, insure that it is dis-
connected from the power supply before you begin.
NOTE: Refer to the wiring diagram on page 17
during installation of your kit.
1. Disconnect your RG5410A from the power source
2. Remove the fasteners from each side of the
RG5410A and separate both halves of the plastic
case.
3. Place the metal frame of the RG5410A in the
upright position
4. Remove the "pry out plug" from the hole located
at the lower right of the front panel, and pass the
tank sensor cord (p/n EL1420) through it.
5. Visually identify the two studs located on the
base, directly behind the lower front panel. (this
will be the location for the relay, p/n EL1500, after
all your electrical connections are made.)
6. Disconnect a red wire from the high-pressure
switch (located under the start switch) Note:
There are two red wires on the high-pressure
switch, disconnect the one that originates from the
Power Switch.
7. Ensure that the terminal multiplier (p/n EL1221) is
placed on terminal #4 of the relay and then place
the red wire removed from the high pressure
switch on that terminal.
8. Place the black wire from the sensor cord on the
other side of the terminal multiplier, on the same
terminal #4 of the relay.
9. Place the white wire from the sensor cord on
terminal #0 of the relay.
10. Connect the white wire from the male side of the
3 pin connector (p/n EL1215) to terminal #1 of
the relay.
Note: Ensure that the green wire from the sensor
cord is connected to the center of the 3-pin connec-
tor. (Note: only two wires are used in this connector).
11. Connect the 3-pin connector to its female coun-
terpart, already pre wired on your RG5410A.
Note: make sure the two wires, (1) green and (1)
white, are in the proper position (directly across)
from their mating wires.
12. Connect one end of the red wire (p/n WR1403),
supplied with your kit, to terminal #2 of the relay
and the other end to the high pressure switch.
13. Secure the relay onto the two studs mentioned in
Step 5, using the hardware already installed on
the studs.
14. Secure the tank sensor into the hole in the front
panel with the strain relief grommet provided.
15. Secure any loose wiring with the wire ties pro-
vided.
16. Replace the plastic case halves and fasteners.
17. Test the installation by momentarily attempting
to start the RG5410A without thesensor cord
connected to a tank sensor. The unit’s compressor
should not start up. Turn the RG5410Aoff and
reattempt to start the unit with the sensor cord
connected to a tank with a tank capacity sensor.
The unit should function normally. Disconnecting
the sensor cord while the unit is running should
cause the unit to shut down.
18. If your unit does not function per above,
DISCONNECT the RG5410A from the Power
Supply, and re-check your connections per the
above steps and the wiring diagram on page 17.
