1.0 Important notes to installers
The successful operation of this unit depends entirely upon
installation and ongoing maintenance being carried out in
accordance with these instructions.
Please read this guide in its entirety before installation and then
repeat the exercise step by step to ensure satisfactory completion.
Suitably qualified persons may achieve installation of the unit,
however the provision of the electrical supply and the connection of
the unit to the mains supply should only be carried out by a qualified
electrician.
The unit can be installed in a home with a “cold roof” construction.
Note: If a floor is higher than 4.5m the requirements in sections
5.2 and 10.2 must be followed.
Note: 3 storey properties must be fitted with an aluminium
diffuser - see section 5.2.
2.0 General description
The unit is a unique low energy Positive Input Ventilation (LEPIV)
unit. Unlike conventional LEPIV units which only draw in external air
via the loft in a “cold roof”, the unit is capable of drawing in external
air from a roof location via an inlet spigot fitted with a low energy
open/close damper.
It is not neessary for the home owner to program or operate the unit
in any way, as the 365 is totally automatic.
The unit intelligently decides where the fresh air will be supplied
from.
If the loft temperature is below 24
O
C then the unit will take fresh air
from the loft.
If the loft temperature is above 24
O
C then cool fresh air will be taken
from outside the dwelling.
If the loft temperature is 19
O
C to 24
O
C and the house is cooler than
this, then the unit goes into heat recovery mode. The unit will increase
in speed and supply more air to the property.
The unit can be boosted to obtain maximum ventilation by the
operation of a boost switch.
S
etting switch is located
on the rear of the fan case.
