For ventilation reasons, all units require a
minimum clearance of 50mm on all sides.
For ease of servicing (where there is

element replacement
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

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.
