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
supplier for advice.
3. INSTALLATION
This boiling water unit shall be installed
by a qualified service person. AS/NZS
3500.4 provides installation guidelines
and it must comply to 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.
For rear entry connection on 3-10 Litre models,
we recommend that you use a braided flexible
hose with a 90° elbow for ease of connection.
