Electrical Connections - Triton TW10i Installation And Operating Instructions Manual

Procedure: Turn off the water supply either at the
mains stop tap or the isolating stopvalve.
Before connecting the supply pipe to the unit,
push the supplied wire mesh filter into the heater
inlet. This helps to prevent ingress of debris.
Ensure the filter is inserted the correct way as
shown in fig.9.
Connect the mains water supply to the inlet of the
unit via 15mm copper or stainless steel pipe using
the nut and olive supplied (fig.10).
Connect the hot water pipe to the outlet side
using the nut and olive supplied.
Ensure the backplate is square on the wall and
tighten the two retaining screws which hold it to
the wall.
Turn on the mains water supply at the isolating
valve, then fully open the sink tap until a smooth
flow of water is obtained. Close the tap and check
for leaks in the pipework connection to the
heater.
