no obstr ctions to or in the d cts
Installation engineers m st follow this man-
al strictly. Improper action can create a
health hazard and red ce efficiency of the
nit
Fresh air vent m st be far eno gh away
from any fl e gas discharge or areas where
hazardo s vapors are present
Unit m st be installed strictly following this
man al and mo nted to a weight bearing
s rface for the weight of the nit
Electric engineering m st follow national
reg lations and the man al, se special ca-
bles. Less capacity cables and improper en-
gineering can ca se electric shock or fire.
D ring maintenance or repair, the nit and
circ it breaker m st be switched off. Other-
wise electric shock co ld occ r.
Gro nd wire cannot be connected to gas
pipe, water pipe, lighting rod or telephone
line etc. Incorrect gro nding can ca se
electric shock.
Power cable and wires m st be installed by
a q alified electrical engineer. Improper
connection can ca se over heating. Fire and
loss of efficiency.
To avoid condensation, ins lation sho ld be
fitted to fresh air d cts. Other d cting may
also req ire ins lation depending on dew
point conditions.
Ins lation between the metal d cting and
wall penetration m st be installed if the
d cting penetrates metal wall cladding, to
avoid risk of electric shock or c rrent leak-
age.
The cover of wiring box m st be pressed
down and closed to avoid d st and dirt en-
tering. Excess d st and dirt can ca se over-
heating of terminals and res lt in fire or
electric shock.
Use only approved installation hardware
and accessories. Fail re to observe can re-
s lt in fire risk, electric shock and eq ip-
ment fail re
Where the nit is positioned, at high level in
a hot h mid sit ation. Please ens re s ffi-
cient ventilation is available
The o tdoor d cts m st be installed facing
downwards to avoid rain water entering.
Improper installation can ca se water leak-
age.
Correctly sized MCB m st be fitted to the
