CTC EcoZenith i550 Pro

For the installer

Zinc-grey screw (4 off)

Plastic top

Fit the plastic top at the front and tip it backwards to locate it under the

mixing valve actuator. Fit the 4 zinc-grey screws provided in the pre-drilled

holes. Ensure that the plastic top cover is correctly aligned with the front.

Graphite screw (25 off)

Tie strap

When the rear insulation is in place, tension bands can be used to hold it

ﬁrmly against the tank. Attach the insulation sections to each other using the

25 graphite-grey screws provided. The screw positions have been pre-drilled.

The tension bands
can scratch the
surface of the insu-
lation. Use a piece
of cardboard or
similar to protect it.
