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
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
keyhole slots at the back of the unit
(refer
to
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

strainer be serviced every six months by
