General Information
The Vectaire WHHR100/60DC heat recovery system provides
whole house mechanical ventilation to living areas, bedrooms, kitchen
and bathrooms. They extract stale, contaminated air from kitchens,
utility rooms and bathrooms, and use the heat recovered from this air
to warm fresh, incoming air to create a flow of fresh air throughout
the dwelling. The extract and intake air streams are separated to
avoid contamination.
Heat is reclaimed from extracted air and used, via the heat exchang-
er, to warm incoming fresh air. The system will operate continuously
to create a stable, comfortable, healthy environment avoiding the use
of excessive energy and saving heat already generated.
The heat recovery unit will generally be installed in the loft of a house
or the void above the ceiling in an apartment (but may be installed in
a cupboard) and will be connected by hidden ductwork to vents sited
in the ceilings of the rooms which require ventilation. Each unit is
commissioned individually allowing its performance to be tailored to
suit the performance required. There will be a facility to boost the
extraction rate when desired (e.g when cooking or bathing or pollutant levels rise). This may be done automati-
cally or manually.
The system is designed to run continuously and should NOT be switched off except for maintenance or filter
replacement.

the sealed or balanced flue type, or allowance must be made for an adequate supply of air into the
room.
•The unit must NOT be be installed:
- where there is excessive oil or grease
- where there are hazardous gases, liquids or vapours that are flammable or corrosive
- in ambient temperatures above 50ºC or lower than 5ºC
- in humidity levels above 90% or in a wet environment
• Where possible the unit should NOT be installed directly above a bedroom or living room.
•The condensation drain must be fitted, and if insulated use the equivalent of at least 25mm of insulating
material with a thermal conductivity of 0.04 W/(mK)
•Care should be taken to ensure that ducting is free from blockages before switching on the unit as this may
invalidate your guarantee
•External grilles should be located a minimum of 600mm from any flue outlet in accordance with all
Regulations
•The unit must be connected to a 230v, 50Hz single phase electrical supply fused at 3A.
•A fused spur box, or triple pole switch having a minimum contact separation of 3mm must be used for
isolation.
•The product should only be connected to the mains electricity supply or electrical outlet if:
- your electrical voltage and frequency correspond to those shown on the rating label.
- the capacity of your electricity supply is sufficiently powerful to operate the product at its
maximum power.
•If one of the spigots is not connected to ducting a safety grille MUST be fitted to that spigot, so that it is
impossible for any moving part to be touched.
• This appliance is not suitable for installation on the outside of a building
Installation of the appliance MUST be carried out by a qualified and suitably competent person and should be car-
ried out in clean, dry conditions where dust and humidity are at minimal levels. It should only be installed after other
building works have been completed and the building in which it is installed cleaned. Failure to comply with any of the
above points will have an impact on the validity of the guarantee.
WHHR100/60DC
Duct and Duct Connections (refer to design drawing)
•4 x 125mm nominal diameter spigots are provided for the connection of ducting. These are clearly marked
for correct connection of the supply and exhaust ducts. Flexible duct fits over the spigots, whilst rigid duct fits
into the spigots.
•Where ducting is installed in an unheated space, all of the ducts should be insulated. Where ducting is in
stalled in a heated space, only the cold ducts should be insulated. i.e. the supply duct from outside and the ex
tract duct from the unit to the outside.
•The duct layout must be designed to suit the requirements of the ventilation/recovery system and building lay
out. If the ducting passes through a fire wall/barrier, suitable fire dampers must be installed.
•Where rigid duct is used, it should be installed using the least number of fittings to minimise air flow resist
ance. Where possible, final connection to the grilles and unit should be made with a flexible connection.
•Where flexible ducts are used, ensure that:
- duct runs are kept as short as possible
- the duct is stretched so that it is smooth and straight
- where bends are necessary, they have large radii (ie avoid sharp bends)
- the duct is not crushed if in a restricted area
•The inlet for the fresh air supply can be directly from outside, or from within a ventilated roof space. If the sup
ply is directly from outside, it must have an external wall grille fitted if supplied through a wall, or a recognised
roof terminal if supplied through a roof. If the supply is from a ventilated roof space, it must be protected by
a filter box.
Condensation
(the unit may sometimes produce condensation which must be drained away. A 15mm dia pipe connection is
provided on this unit).
•A 15mm dia pipe must be fitted to the pipe connection. If any part of the condensate drain is in an
unheated space it MUST be insulated with the equivalent of at least 25mm of insulating material with a
thermal conductivity of 0.04 W/(mK).
•The drain must incorporate a U-bend to prevent air penetration.
•The pipe must drain into the normal household drainage system.
•The unit must be tilted towards the side carryng the condensation exit point. It should be installed
horizontally with a 3º tilt towards the condensation drain used (equivalent of raising the opposite end by
approximately 25mm).
•. Four possible condensation drain points are provided, which allow the installer to turn the unit through 180O
to simplify duct layout and connections.
Electrical Connection
WARNING: these appliances must be earthed and all wiring must conform to current IEE Regulations and
all applicable standards and Building Regulations.
• The unit is suitable for 230V, 50Hz Single phase supply fused at 3A.
• The unit is supplied with a mains rated 4 core flexible cord (black, brown, grey and green/yellow)
• A triple pole isolation switch with contact separation of at least 3mm must be used to connect the appli-
ance to the fixed wiring when using the Switched Live.
• Boost controls must not be located within 1 metre of a cooker or where they may be affected by
excessive heat or moisture
• Boost controls should be clearly identified and conveniently located.
• The boost switch wiring cable access is via a 12mm cable gland.
• The boost speed can be triggered by a switched live connection from a variety of external devices including:
- PIRFF (passive infra red)*
- DRH240 (dynamic remote humidistat)*
- THM (thermostat)*
- a light switch (if more than one light switch is used, each one must be a double pole switch)
- a remote switch/pull cord
(*PIRFF, DRH240 and THM may have integral over-run timer which controls the length of time that the fan
will continue to operate at its boost speed after the boost has been switched off.)
Commissioning
•The units operate by extracting warm, stale air from kitchens, WCs, bathrooms etc, and passing it into a heat
exchanger and out to the atmosphere. Another fan draws in cool, fresh air and passes it through the same
heat exchanger, where it is heated by the outgoing, stale air.
•When the unit is set up and running, the minimum setting on the speed control switch must relate to the
designed volume air flow. The variable air flow from minimum to maximum allows the unit to extract a greater
volume to cope with any increase in the build up of condensation or foul air, ie cooking etc.
•Before starting the commissioning procedure, refer to the design drawing for correct air flows.
N.B extract and supply air volumes will not always be equal. When setting up, therefore, the extract system
should be the datum.
Installation of the appliance MUST be carried out by a qualified and suitably competent person and should be car-
ried out in clean, dry conditions where dust and humidity are at minimal levels. It should only be installed after other
building works have been completed and the building in which it is installed cleaned. Failure to comply with any of the
above points will have an impact on the validity of the guarantee.
Commissioning Procedure
•Ensure that the exhaust and supply grilles or valves are open.
•Turn the electrical supply ON and set the fan speed control to TRICKLE.
•Check the air flows at the grilles or valves, and adjust to suit the design figures by turning the centre of the
valve clockwise to decrease the airflow, and anticlockwise to increase the airflow.
•If the airflow is still not correct proceed as follows:
- turn the electrical supply OFF
- remove the electrical access cover
- locate the trickle speed adjustment (see Wiring Diagrams) and adjust as required.
- turn the electrical supply ON.
•Re-measure the air flows at the grilles or valves as detailed above, and repeat the procedure until the correct
air flows are achieved.
•Adjust the Boost Speed to requirement and ensure that the air flows increase when the boost switch is acti
vated.
Cleaning and Maintenance
WARNING: The unit uses a 230V supply and contains rotating mechanical parts.
• Before carrying out any maintenance or cleaning operations the mains electrical supply MUST be dis-
connected.
