AUTOMATIC MAKE-UP WATER LEVEL CONTROLLER—WLC-100
A. Pool water level shall be maintained by an automatic make-up level controller Model WLC-100.
B. Controller package shall consist of a PVC chamber to house stainless steel probes, a liquid level
relay and delay timer, 110v 24-hour timer and terminal board.
C. Water level shall be controlled by the use of a three-probe electrode system, one for high level, one
for low level and one ground. Electrodes shall be T316 stainless steel connected to a UL approved
probe holder. A mechanical linkage or float operated system will not be acceptable.
D. Probes and holders shall be housed in a PVC chamber consisting of an 8", schedule 80 PVC pipe.
Chamber shall be sized to accommodate desired range of water level variation and shall be complete
with removable cover and adjustable collar suitable for deck level installation. A 1 ½", equalizing
line shall be connected from the bottom of the chamber to the pool wall.
E. Probes shall be mounted on a readily removable plastic disk within the chamber. Probe connectors
shall be protected with 90º molded plastic holders. Probe holders allow for +/- ½" of elevation
adjustment.
F. Wiring from the probes shall be connected to a UL approved relay mounted within the Control
Panel.
G. A 24 hour, 110v time clock shall be provided to allow for variable time settings of operation for the
WLC system. Clock shall be provided with a manual override.
H. Solenoid valve size shall be as indicated on drawing, N.C., slow closing.

AUTOMATIC MAKE-UP WATER LEVEL CONTROLLER—WLC-300
A. Pool water level shall be maintained by an automatic water level controller Model WLC-300.
B. Controller package shall consist of a PVC probe chamber, stainless steel probes, and a solid state
relay with NEMA 1 enclosure. Unit shall be Neptune-Benson Model WLC-300 water level
controller or approved equal.
C. Water level shall be controlled by the use of a three probe electrode system; high level, low level and
ground.
D. Probes and holder shall be housed in a PVC chamber consisting of an 8" schedule 80 PVC pipe. The
chamber is sized to accommodate the desired range of water level variation and shall be complete
with a removable cover and adjustable collar suitable for deck level installation. A 1 ½" line shall be
connected to the bottom of the probe chamber from the pool wall to reflect the water level in the
pool.
E. Probes shall be mounted on a readily removable plastic disc within the probe chamber. Probe
connectors shall be protected with 90º molded plastic holders. Probe holders allow for +/- ½" of
elevation adjustment.
F. Wiring from the probes shall be connected to the relay that is to be mounted within a NEMA 1
enclosure.
G. Unit shall be suitable to activate any 110 volt or 230 volt circuit for solenoid valve, pump or other
method of providing makeup water.
H. Solenoid valve size shall be as indicated on drawing, N.C., slow closing.
