7. Install plumbing waste traps and strainers with a maximum of 10 mm diameter apertures in the inlet pipes to
prevent excessively large solids passing through.
8.3 Electrical Connection
1. The WALLACE UNI-SAN is fitted with a high quality 2900 rpm 2 pole speed motor :
Current :
2.45 amps FLC
Motor output :
0.4 kW
Cable:
1.5 metres of 3 core - supplied with the unit
Connection Plug : Standard 3 pin domestic earthed - supplied with the unit
Supply :
Single phase 230 volts 50 Hz.
2. Overload protection (thermal / overload) : the unit has a built-in automatically resetting motor overload. In the
event of a fault and trip, the pump may restart without warning. If the pump continually cycles on and off, switch
the power off and refer to the fault-finding section (Appendix B ).
3. Wiring connection : the electrical wiring connection type should preferably be the "Clipsal Permanent Connection
Unit with Neon" type, or PDL 253N, or similar. The permanent connection should be fixed in a position where it
cannot be reached by a person in a bath or shower or standing on a wet surface.
4. The unit requires a domestic 3 pin earthed single phase power supply. The appliance must
not
be connected
to a conventional plug, socket or adaptor when installed in a bathroom, unless properly protected by an approved
earth leakage circuit breaker or similar.
5. Refer Section 6 ( Warning : for your safety ) for additional electrical information.
Always refer to your local power supply authority for details of acceptable wiring, as their requirements over-ride the
guidelines above.

32 mm Waste Pipe
PUMP DELIVERY from UNI-SAN to approved termination
25 mm PVC
Class B/D/4.5 Pressure Pipe
Note : Choice of pipework sizes vary with state and local plumbing regulations.
9.2 Layout And Pipe-Out Options
The waste inlet valve sockets and Bottom Inlet Valve(s) can be installed in
any of the four walls, or in the top of the collection tank.
No inlet fittings or inflows should be in line with the operating range, or on top of the float switch.
The vent pipe must be installed in the top of the tank, anywhere around the inspection lid.
The pump is supplied with the delivery outlet out the end of the unit. If necessary and on request Wallace Pumps
can supply prior to despatch of the pump from our store with the outlet set to deliver out either side.
9.3 Positioning And Marking Out
Decide which way round to install the UNI-SAN unit.
Place the unit in position. At this stage, you must visualise where the pipes will run from fixtures to the unit, where
the tank vent pipe and delivery pipe will run from the unit. Ensure that the whole system will integrate correctly in
terms of gravity fall requirements before proceeding.
If the UNI-SAN Bottom Inlet Valve is used, mark the centreline position(s) at 80 mm height above the base of the
unit, and no closer than 45 mm centreline from the side of the unit. If a valve socket is used, allow room for the
back-nut inside the tank to be at least 40 mm away from the fittings inside the tank and the corners of the tank and
check that the pipe protrusion is clear of the vent tube, the float level switch and its movement operation. View
through the inspection lid before cutting the hole.
Decide on the position of the vent pipe in the top of the tank. Mark the centreline for a 42 mm O.D hole to take the
32 mm valve socket, allowing room for the fitment of the washer and back-nut inside the tank.
