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.

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.

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.

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).

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.

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.

3. INSTALLATION

This boiling water unit shall be inst alled
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.

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.

A. LOCATION

This unit is designed for interior
installation only.

B. OPENING 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.

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.

3.

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.

F. OVERFLOW / VENT
CONNECTION IMPORTANCE

Connect a 15 mm (½”) pipe to the
overflow/vent connection (½”BSP
nipple). This pipe is to be made of a
material such that continuous steam will
not degrade it (i.e. copper). This pipe
must have a continuous fall, not
exceeding 3 metres in length and / or
contain no more than 4 bends ( refe r to
figure 2).

Figure 1: Water Connection

If the site situation requires a pipe length
exceeding 3 metres, then discharge the
overflow/drain into a tundish.
The drain pipe work must not exert a
pressure of more than 1 metre of head on
the Lazer boiling unit (refer to figure 2).

During normal operation of the Lazer, the
overflow/vent connection may discharge
small quantities of steam and condensate,
so it is ESSENTIAL that the drain pipe is
attached to the overflow vent connection.
This drain pipe must discharge to waste at
a point where no scald injury, nuisance n or
inconvenience is caused to people in the
immediate vicinity.

WARNINGS:

Ensure the overflow/vent line remains open
because the Lazer’s tank is not designed to
be pressurised. Where freezing may occur,
protect the pipes and install an air break. It
is recommended to install an air break in
the overflow/vent drain line, no more than
300 mm from the Lazer unit. Also it is
important to connect the overflow/vent and
water inlet correctly. Incorrect connection of
pipe work may damage the unit.

G. DRAIN

WARNING:

Before drainin g the unit, ensure t he
appliance has been switched off,
and water is not hot enough to
scald.

To drain 3-10L models, turn unit off and
open tap until no water flows out. Remove
unit from wall and tip over with tap open
until unit is empty. For 15-40L units. A drain
plug is accessible from the bottom of the
unit (note switch unit off before draining)

IMPORTANT

Installation and maintenance of the Lazer Boiling Water

unit shall be carried out by a qualified service person.
