GENERAL INFORMATION
The Vectaire Studio heat recovery system provides mechanica ven-
ti ation to bedrooms and bathrooms. It extracts sta e, contaminated
air from bathrooms, rep aces it with fresh air to the bedroom and
vents the sta e air to the outside.
Heat is rec aimed from the extracted air and used, via a heat
exchanger, to warm the incoming fresh air. The extract and intake
airstreams are comp ete y separate to avoid cross-contamination.
The system operates continuous y and is designed not be switched
off, except for maintenance purposes.
During norma operation, the unit produces a ow-vo ume airf ow,
creating a comfortab e, hea thy environment, with minimum energy consumption.
If additiona venti ation is required, (e.g. when a shower is in use), a boost faci ity is
inc uded which increases the airf ow rate. The boost can be operated automatica y
or manua y.
Insta ation of the unit is usua y above a cei ing or in a oft space and is connected
to air vents via hidden ductwork.
Each unit is commissioned individua y a owing its performance to be matched to the size of area to be ven-
ti ated.
STANDARD FEATURES
1. Variab e adjustment of ow (trick e) and boost speeds for optimum setting at insta ation.
2. Adjustab e overrun timer on boost setting - factory set to zero.
3. Adjustab e de ay-on timer, factory set to 2 minutes
4. Adjustab e night-time boost inhibitor set to operate from 10.00 p.m to 6.00 a.m
5. Mu tip e choice of externa devices for automatic or manua boost switching (e.g. ight switch, remote
switch/pu cord, PIRFF passive infra-red*, DRH240 humidistat*, THM thermostat*.)

INSTALLATION
Installation must be carried out by a suitably qualified person and must comply with all current building
regulations and electrical installation regulations.
Mounting the unit
Before choosing the position for mounting, it is important to take into consideration the ductwork routes
and condensate drain route. The four spigots on the unit are marked for the four unique connections. The
unit can be supp ied eft or right-handed in order to match the required duct routes more easi y. (Factory
option on y.)
It is also essential that adequate access to the
product is provided for maintenance or removal
after installation. The entire access panel needs to
be removed for maintenance.
The unit is intended to be suspended from a cei ing
or simi ar fixture. Two identica fixing brackets are
supp ied with each unit. It is important that the unit
is attached to ithese brackets so that there is a s ope
down towards the condensation drain connector of
the product. When correct y fitted, the brackets wi
provide a drop of approximate y 15mm at the ower
end.
Duct and Duct Connections (refer to design drawing)
1.4 x 125mm nomina diameter spigots are provided for the connection of ducting. These are c ear y
marked for correct connection of the supp y and exhaust ducts.
2. Where ducting is insta ed in an unheated space, a of the ducts shou d be insu ated. Where ducting is
insta ed in a heated space, on y the co d ducts shou d be insu ated. i.e. the supp y duct from outside and
the extract duct from the unit to the outside.
3.The duct ayout must be designed to suit the requirements of the venti ation/heat recovery system and
bui ding ayout. If the ducting passes through a fire wa /barrier, suitab e fire dampers must be
insta ed.
4. Where rigid duct is used (preferab e), it shou d be insta ed using the east number of fittings to min
imise air f ow resistance. Where possib e, fina connection to the gri es and unit shou d be made with
a f exib e connection.
5. Where f exib e ducts are used, ensure that:
- duct runs are kept as short as possib e
- the duct is stretched so that it is smooth and straight
- where bends are necessary, they have arge radii (ie avoid sharp bends)
- the duct is not crushed if in a restricted area
Note: Whenever the unit is insta ed in c ose proximity to a bedroom or other habitab e space, we recom-
mend that sound attenuation is provided within the duct runs between the rooms and the unit. A ength of
1 metre of f exib e acoustic ducting wi be sufficient in most circumstances, but reference shou d be made
to the sound data provided for this product
