Before Use
TE-10D And TU-20D Only
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.
All Models
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.
