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 (refer 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 nor 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 draining the unit, ensure
the 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.
