2.0 INTRODUCTION
The unit is a unique low energy Positive Input Ventilation (PIV) unit.
Unlike conventional PIV 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 necessary for the home owner to program or operate the unit
in any way, as the 365 is fully automatic and intelligently decides which
location the fresh air will be supplied from.
If the loft temperature is below 24°C then the unit will take fresh air
from the loft. If the loft temperature is above 24°C then cool fresh air
will be taken from outside the dwelling. If the loft temperature is 19°C
to 24°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.
3.0 MECHANICAL INSTALLATION
Successful operation of the fan depends entirely upon the unit being
installed strictly in accordance with these instructions. Please read
through this guide in its entirety before commencing installation and
follow step by step to ensure a satisfactory completion.
Installation must be completed by competent persons, in accordance
with good industry practice and should conform to all governing and
statutory bodies i.e. IEE, CIBSE, etc.
Isolate from power supply before removing any covers. During
installation / maintenance ensure all covers are fitted before switching
on the mains supply.
All-pole disconnection from the mains as shown in the wiring diagram
must be incorporated within the fixed wiring and shall have a minimum
contact separation of 3mm in accordance with latest edition of the
wiring regulations.
Precautions must be taken to avoid the back-flow of gases into the
room from the open flue of gas or other fuel-burning appliances.
This appliance should not be used by children or persons with reduced
physical, sensory or mental capabilities or lack of experience and
knowledge, unless they have been given supervision or instruction
concerning the safe use of the appliance by a person responsible for
their safety. Children shall not play with the appliance. Cleaning and
user maintenance shall not be carried out by children.
CAUTION: In order to avoid a hazard due to inadvertent resetting
of the thermal cut-out, this appliance must not be supplied
through an external switching device, such as a timer, or connected
to a circuit that is regularly switched on and off by the utility.
3.1 Loft Inspection
Check to ensure that the loft has adequate ventilation. There may be
occasions where a loft is so well sealed that additional ventilation may
have to be provided by the owner/occupier.
Ensure that all water tanks are covered and sealed.
Check that all water pipes are lagged.
Ensure that any extract fans are discharging to outside and not into the
loft.
Check that the loft hatch is tightly sealed.
Ensure that all holes in the ceilings are sealed i.e. ceiling light fittings
etc. A visual inspection of any flues or chimneys for leakage in the loft
should be carried out by the installer. If any leakage points are found,
or if there is any doubt at all, then the installer should advise the house
owner/provider as soon as possible and seek instruction from them
before proceeding with the installation.
