Set Up
1 There are two modes of operation for the pump; circulation internal to the bath; circulation external
to the bath. For internal circulation the blanking caps on the top of the outlet and return pipes
should be securely in place. They screw on and, for safety, they may be tight. For external circulation
these need to be removed.
The outlet nozzle is supplied fitted to the bottom of the pump housing in the internal circulation
position. In this position and with the blanking cap on the outlet pipe the pump will circulate
internally.
If maximum external flow is required: Remove the outlet nozzle from the pump base and reposition
it on the bottom of the return pipe. Remove the blanking cap from the return pipe and screw it onto
the hole from which the nozzle was taken. This redirects the full flow externally. Screw the pipe
connectors supplied with the unit to connect the appropriate pipe to the unit.

2 CAUTION: DO NOT SWITCH THE THERMOREGULATOR ON UNLESS EITHER THE
BLANKING PLUGS ARE FITTED TO THE TOP OF THE PIPES or AN EXTERNAL CIRCUIT IS
FULLY CONNECTED. NEVER SET THE UNIT SO THAT THE FLOW IS SPLIT INTERNALLY AND
EXTERNALLY.
3 Ensure that the bath is set up on a flat level surface.
4 Fit the unit securely to the bath using the correct bridge piece for the unit/bath or a portable clamp,
see the list of accessories. THE UNIT MUST ALWAYS BE MOUNTED WITH THE BACK AND
THE SWITCH END OUTSIDE THE AREA OF THE BATH. This will reduce the infiltration of hot
vapours into the cooling system of the thermoregulator. Ensure that at all times the air inlet and
outlet remain clear of obstructions. Free circulation of air inside the unit is essential for proper
cooling of the electronics and pump motor.
