ELECTRICAL CONNECTIONS
1. Shut off electrical power at fuse box before making any connections. All wiring must comply with local
codes.
2. Line voltage: Connect pump to voltage specified on label located on pump. Wiring is as follows:
Live - Brown
Neutral - Blue
Earth - Yellow/Green
3. If fused plug is used, a 1.0 amp fuse is recommended.
4. High level float switch connection options. The pump is fitted with a secondary float which will trigger a micro
switch just before the pump starts to over spill. This switch can be used to either switch off the boiler or signal
an external alarm (visual or audible alarms are available as option extras). The following diagrams show how
the high level float switch can be connected. (Fig 3 and Fig 4).
It is strongly recommended that either of these options is selected, if the pump where ever to over spill
the dilute acid condensate could cause damage to property.

WATER DRAIN CONNECTIONS
Inlet Water Connections
1. Position pump beneath boiler condensate drain so that condensate flows into the pump inlet freely (use any
of the three openings provided).
2. The pump will accept up to three drain lines, although care should be used to make certain that total inflow
does not exceed outflow of pump. If more drains into the pump than the rated output of the pump, tank may
overflow.
3. Keep plugs in unused pump inlet openings to prevent debris from falling into the pump tank.
Outlet Water Connections
1. Connect the supplied 3/8" I.D. tubing to the non return valve (Fig 1). For best results, secure tubing with
clamps (not provided) but do not pinch collapse or otherwise restrict the tubing.
2. The pump is supplied with an adaptor which can be connected to standard 22mm pipe or with associated
adaptors (not supplied) to 32mm and 40mm pipe.
3. Tubing should rise vertically but not exceed the maximum shut off head (pumping height) of 4.3 metre above
the pump.
4. At highest point angle tubing horizontally and create a downward slope to the drainage point. Do not sharply
bend or twist the tubing in a way that might result in collapse or restriction of the tubing. Creating a downward
slope will allow the condensate to drain by gravity and keep tubing empty.
5. If it is not possible to create a downward slope, try to create an inverted

trap directly above the pump at
the highest point.
