Installation and Maintenance
FLATMASTER Low Energy Positive Input Ventilation Unit
2.2.1 Points to consider
•The inlet ducting should be kept as short as possible to avoid condensation
build up on the ducting surface (see fig. 5 and 6).
•Find the shortest, most direct route from outside of the unit and then to
the discharge grille using the least number of bends (these bends increase
the airflow resistance).
•Note the location of any joists, pipes, electrical cables etc.
•Allow adequate access to the front cover to allow filter cleaning.

2.3.1 Fitting the deflector plate
Fit deflector plate into scroll cover as shown below. Once fitted the
assembly can be slotted into the scroll and clipped firmly in place.

2.3.2 Transformation Piece
This should be on the appropriate scroll outlet. The transformation
piece should be fitted into the chosen outlet spigot insert, prior to
fitting.
Note: If the round spigot is used as an outlet, the 115 x 55mm clear
blanking plate will need to be fitted (as shown). This plate should be
prevented from movement by the use of silicone sealant.

2.4 Fitting of ducts
To prevent access to live or moving parts ensure ducts are adequately
secured to the spigots by fitting self tapping screws or by other means
requiring a tool. If using duct tape ensure tape cannot be removed
without the use of a tool by securing with tie wraps.
