35B. THREE PHASE UNITS (except IST or STP units
with VS2 or VS4 sufx): Connect the ground wire
to the lug in the junction box. Connect any three
wires from the pump to any three wires from the
three-phase power source using the wire nuts
supplied (from hardware pack p / n 400301902).
Capacitors are not needed for three phase units.
Install a pressure gauge in the line test port
(see Figure 15), turn on the pump, and read the
pressure gauge. Turn off the pump at the power
supply, and change the connection of any two
wires at the pump. Turn the pump back on and
read the pressure gauge again. The electrical
connection that gives the higher reading on the
pressure gauge is the correct one.
35C. IST UNITS or STP units with a VS2 or VS4 sufx:
Connect the ground wire coming from indoors to
the ground lug in the junction box. Connect any
three wires from the pump connector assembly to
the three power wires coming from the Variable
Frequency Controller (VFC). Capacitors are
not needed for these units. Detailed installation
instructions for the VFC should be referenced
when connecting the VFC. These are supplied
with the VFC.
Not installing a ground wire increases
the risk of lethal electric shock and
equipment failure. All holes of the
compression seal (contractors plug)
must be lled with wires or a celcon rod
to enable it to seal.
36. Replace the junction box cover and tighten
securely.
The pump discharge manifold has
two labeled ports: one for the syphon
system and one for the tank. A piston
leak detector must be vented to the tank
port (lower port) only. Do not connect a
piston leak detector to the syphon port
because this will make the leak detector
inoperative, resulting in an increased
risk of contamination of the environment
(see tank port in Figure 14).
37. Connect power to the submersible pump at the
electrical supply box.
38. Test proper operation by dispensing product into
calibration can.
39. Turn off the dispenser switch. Feel the
submersible pump to make sure that the pump has
stopped running.
Note: If the pump does not turn off when the dispenser
switch is turned off, this may indicate an electrical
problem in the dispenser or other wiring error or
malfunction. Call this to the immediate attention of
a qualied electrician.
40. Visually check for leaks on the manifold head
during pump operation and after.
41. Install a pressure gauge in the line test port to
ensure that the STP / IST is providing proper line
pressure.
42. Turn on the STP / IST. While running, the pressure
should be above 24 psi (1.65 bar). PMA size will
affect psi.
43. Turn off the STP / IST and verify that the line
pressure is holding.
44. Remove the pressure gauge and replace the plug.
45. Turn on the STP / IST and, again, visually check for
any leaks.
