Assembly – Electric installation and electric connection EN
Safety instructions:
Beware! Any assembly work to the ventilation device may only be carried out when all phases
of supply voltage have been disconnected!
Make sure that the supply voltage of all connection lines is dead! (separation from the power
supply with a free space between contacts of at least 3 mm, e.g. all-phase disconnecting electr.
protection).
Each electric circuit of this ventilation system must be fitted with a residual current protection
(e.g. RCD)!
WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a.) Installation work and electrical wiring must be done by qualified person(s) in
accordance with all applicable codes and standards, including fire-rated construction.
b.) Sufficient air is needed for proper combustion and exhausting of gases through
the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating
equipment manufacturer’s guideline and safety standards such as those published by the
National Fire Protection Association (NFPA), and the American Society for Heating, Refri-
geration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
c.) When cutting or drilling into wall or ceiling, do not damage electrical wiring and
other hidden utilities.
d.) Ducted fans must always be vented to the outdoors.
e.) If this unit is to be installed over a tub or shower, it must be marked as appropri-
ate for the application and be connected to a GFCI (Ground Fault Circuit Interrupter) –
protected branch circuit.
The product’s installation shall not conflict with any requirement in the National Electrical Code,
ANSI/NFPA 70-1999.
Additional installations and electrical components in this ventilation system are prohibited!
The system is controled by Univer-
sal Control 5/UNI or Touch Air
Comfort TAC. Look for the installa-
tion instructions.
Select the position of the switch.
Slit the cable ducts (power cable +
cable to the device pairs). Lay the
power cable (e.g. 3 x AWG18) and
the cables to the pairs of devices
(e.g. 3 x AWG20). Circuit and
switch are connected like the dia-
gramm below.
