LAZER BOILING WATER UNIT
INSTALLATION AND OWNERS GUIDE
Thank you for choosing our Lazer Boiling
Water Unit. Please take a few minutes to
read this booklet because it contains
important information about the correct
installation and operation of your Lazer
unit.
1.
WARNING:
This Lazer unit produces boiling water
(third degree burns may occur) and care
should be taken at all times when using it.
This unit is not intended for use by infirm
persons and young children should be
supervised to ensure that they do not play
with the unit.
2. WATER QUALITY
Caution is suggested if the Boiling Water
Unit is to be connected to a water supply
with a high content of silica or calcium.
Water supplies of this nature may be
detrimental to the unit’s operation and
may cause the warranty to become void.
For further information relating to the
guidelines of water quality, contact your
local Rheem office for advice.
3. INSTALLATION
This boiling water unit shall be installed by
a qualified service person. The installation
must comply with AS/NZS 3500.4 and all
relevant
statutory
and
local
body
requirements of the state in which the
Boiling Water Unit is installed.
A. LOCATION
This
unit
is
designed
for
interior
installation only.
B. OPENING THE UNIT
To remove the jacket from models 3, 5,
7.5 & 10 L remove the 4 retaining screws
at the top and bottom and pull the jacket
forward. For models 15, 25 and 40 L
unscrew the lid at the top and service
plate on the left hand side.
C. MINIMUM CLEARANCES
For ventilation reasons, all units require a
minimum clearance of 50mm on all sides.
For ease of servicing (where there is
sufficient space) we recommend 300mm
clearance from the top of all units.
For
element
replacement
reasons
we
recommend clearance of 150mm from
the right hand side of 3 to 10 litre units
and 300mm from the left hand side of the
15 to 40 litre units.
D. MOUNTING
The Lazer when installed is suspended
from mounting screws located into
keyhole slots at the back of the unit
(refer
to
the
Mounting
Dimension
Specification on page 6).
Be sure that the mounting screws are
securely inserted into the keyhole slots.
The screws MUST be anchored in such a
way, that they will hold the weight of the
unit when filled with water, (refer to the
specification table on page 5).
WARNING:
Before drilling into the wall make sure
that the screw positions avoid any pipe-
work or electrical cables. Allow 4 mm
clearance between the screw head and
the wall for locating the unit.
E. WATER SUPPLY CONNECTION
Cold mains pressure water (refer to
specification table on page 5 for minimum
water pressures) must be piped and
connected to the ½” BSP inlet fitting
located on the left hand side underneath
the unit. An accessible isolating valve
must be installed near the unit.
This unit contains an inlet strainer on the
water inlet connection (refer to figure 1).
To
ensure
continuing
satisfactory
operation, it is suggested that the inlet
strainer be serviced every six months by
a qualified service person. Where poor
water
quality
is
present
it
is
recommended to install an additional
auxiliary filter.
