PREPARATION & POSITIONING
7.1
DUCT INFORMATION
7.1.1
It is an advantage to have all the compatible ductwork already installed and ready to connect to
the spigots.
7.1.2
Ducting passing through unheated roof voids should be insulated. Ducting runs should be as
straight as possible and the horizontal exhaust ducting should always slope downwards from the
Q-Vent CE50 unit.
7.1.3
The recommended type of ducting is ridged 125mm
ø or
202mm x 60mm rectangle plastic duct.
The final connection can be made with 125mm
ø
flexible duct.
7.1.4
Any exhaust duct passing through a roof use a suitable Vertical Terminal or Ridge Terminal. For
details on these contact our sales department for further information.
7.2
POSITION OF THE UNIT
7.2.1 Ensure there is adequate access for installation and maintenance. Installation can be at any 90˚
angle. Ensure the selected electrical mains wiring has an isolator near the unit for servicing.
7.2.2 Position the Q-Vent CE50 unit taking into consideration the position of the rooms being ventilated,
the exhaust exit position and electrical services. Also make sure when choosing you take into
consideration the accessibility of the commissioning control.
7.2.3 It is the responsibility of the installer to ensure all aspects of the system design are taken into
consideration. The Q-Vent CE50 is designed as a ducted unit and should only be used in ducted
situations.
7.2.4 The unit has one stale air inlet spigot and one exhaust air outlet spigot.
