INTRODUCTION

The STAINLESS UV Unvented cylinder is made

from Duplex Stainless Steel for excellent corrosion

resistance. STAINLESS UV has a strong rust-proofed

steel case and is highly insulated with environmentally

friendly foam.

STAINLESS UV is supplied complete with all the

necessary safety and control devices needed to

connect to the cold water mains. All are pre-adjusted.

High quality controls have been selected to combine

high ﬂow rate performance with minimum pressure

drop to make STAINLESS UV perform well in all areas,

even those with poor water pressure.

IMPORTANT NOTE TO

THE INSTALLER

Read these instructions before commencing installation.

Unvented cylinders are a controlled service as deﬁned in

the latest edition of the building regulations and should

only be ﬁtted by a competent person.

The relevant regulations are: England and Wales –

Building Regulation G3, Scotland – Technical Standard

P3, N Ireland – Building Regulation Part F

After installation the Benchmark check list must be

completed and left, with these instructions, with the

householder for future reference.
