5 Begin by securing the bridge piece to the bath. Use the two M4 countersunk stainless screws and
screw into the holes in the corners of the bath.
6 Locate the thermoregulator above the bridge piece. Toggle the heating element carefully through the
clearance hole. Lower the thermoregulator onto the M4 threaded stud (1) and 3mm diameter stud
(2). Use the half-turn plastic fastener (3) to clamp down the thermoregulator.
7 Use the thumb screw (4) to secure the cover plate to the bridge. Bungs (5 and 6) are provided to seal
off the holes in the bridge piece. It is necessary to fit the bungs to reduce heat losses and prevent
steam or other vapours getting to the thermoregulator.
