Waterco Aquamaster

INSTALLATION
1. The ‘Flocheck’ valve should be placed at the end of a straight length of pipe at least 500mm long
and before the integrated take-off point. Mounting the valve in this position assumes the water
flow is not turbulent at the point of sensing. This is important in order to avoid multiple starts of
the boost pump / integrated pump.
2. The valve can be installed in horizontal or vertical pipe. The probe stem should be upright if
installation is in the horizontal position for correct action.
3. The valve must be fitted to the direction of the water flow as indicated on the valve body.
4. WARNING: when gluing into the line, use cement sparingly so flap is not inadvertently glued in
the closed or open position.
5. Remove small bridging plug from the socket of the controller (if present). Push in the plug of the
‘Flocheck’ valve to the controller.
WARNING:
The sensing switch in the unit is rated in milliamps NOT AMPS and will not directly
switch 240 VAC power.
FLOW SENSING
PRE-SET THRESHOLD FLOW
The valve has a factory setting ‘switch-on’ threshold water flow of 60 litre/min and ‘switch-off’ (30
l/min) threshold point. To change the threshold point the following procedure is to be performed.
(a) Holding the sensing stem to prevent movement, slightly loosen the knurled lockseal nut.
(b) Slide the sensing stem to the new position required to accept the water flow characteristics of
that particular filter system. The threshold flow is increased by pulling the sensing stem further
out from the body and conversely decreased by pushing the stem into the body.
(c) Lock the stem into position with the knurled lock seal nut.
(d) Check correct operation of the flow switch. With the integrated pump operating, stop and start
the filter system several times.
If the pump continues to operate when there is no water flow, check the functionality of the hinged
valve inside the unit for correct operation and debris.
WARNING:
when gluing into the line, use cement sparingly so flap is not inadvertently glued in the
closed or open position.
Remove small bridging plug from the socket of the controller (if present).
Push in the plug of the ‘Flocheck’ valve to the controller.
WARNING:
the switch in the unit is only rated in milliamps NOT AMPS and will not directly switch
to 240 VAC power. Unit is to be connected to the terminal provided in the Aquamaster.
ELECTRICAL
Ensure power is disconnected prior to wiring Aquamaster.
• Follow all statutory and local wiring and installation regulations
• Use copper conductors only
The Aquamaster requires both high and low voltage connections.
To gain access to the wiring compartment, insert a flat blade
screw driver and half turn anti-clock wise to release the spring
loaded locking pin in each corner. Ensure the pins are fully
released prior to opening the hinged front panel. The hinged
panel may be removed by lifting it upwards from the hinge
pins. All connections will be made to the printed circuit board
(PCB) inside the control box. These connections include mains
supply, hard wired inputs and outputs, actuators, sensors and
dry contacts for heater control. When cabling is wired into the
Aquamaster Control Enclosure all cable entry points must be
sealed to prevent ingress of moisture.
