When n timers are continuously installed , the dimension
( A ) is calculated according to the following formula ( n:
the number of the timers to be installed ) :
A= ( 48 × n – 2.5 ) +0.6
Note) 1: The installation panel thickness should be between 1
and 5 mm .039 and .197
Note) 2: For connected installations, the waterproofing ability
between the unit and installation panel is lost.
