11.1 Motor Connection: The electrical connection
between the WM -module and control box for the RO
pump motor is with the self-locking female and male
plugs. Push Male Plug into Female Plug and turn to
lock.
11.2 Connecting Inlet Solenoid and Low Pressure
Switch (LLP) to control box:
The pink female spade connector RED and BLACK
wires plug into the male terminals of the inlet solenoid
coil as shown in drawing below.
The Blue color female spade connectors WHITE and
GREEN wires plug into the male terminals of the LLP
Switch that are marked COM (common) and N/O
(normally open) as shown in drawing below.
If any of the 2 wires to the LPP switch are installed on
the terminal marked N/C the WM -PT will not operate.
11.3 TSO (Tank Pressure switch) connection:
Male Molex Plug on the TSO (Tank Pressure Switch)
plugs into the Female Molex Plug from the control
box. The Yellow and Brown wire are for the TSO.
The TSO is pre-set at the factory with a setting of
40 / 60 psi. The WM will shut down when the
pressure in the pressurized storage tank reaches 60
psi and will start up then the pressure in the tank
drop to 40 psi or below.
12.0 START UP:
All pre-treatment equipment should have been started
up and be in service before starting up the WM -
System.
12.1 Flush valve
The WM has a built in flush valve after the pre-
treatment. The flush valve allows to purge both air
and carbon fines out of the pre-filters. A water line
should be attached to the outlet of the flush valve and
run to a drain or into a pail. Open flush valve and turn
on water supply to WM -System. Flush water through
pre-filter for 5 minute or until water run clear of
carbon fines and air. Turn flush valve to the off
position.
12.2 Disconnect Permeate Line from Storage Tank
For start up disconnect RO Blue ¼” Poly Tubing from
the storage tank. This way you will be able to see the
production of RO water and be able to adjust
production of the unit and set the recovery rate.
12.3 Drain Control Needle Valve .
Fully open the Drain Control Needle Valve by turning
counter clockwise until it stops. Make sure the
Recycle Needle Valve is fully closed by turning
clockwise. (See Drawing below)
12.4 Connecting to electrical supply.
The toggle switch on the WM -control box must be in
the off position. Plug the power cord of the WM -
control box into electrical outlet. NOTE if wired for
220 volts at connector plug will need to be installed on
the power cord or hard wired into electrical disconnect
box.
