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
.
The air filters and heat exchanger of the Vectaire WHHR100/90DC should be cleaned regularly by a
suitably qualified person (the frequency of cleaning will vary depending on the installation environment). Filters
should be replaced after a maximum of 3 cleaning cycles.
Filter and Heat Exchanger access:
•
Remove the centre screw and the four corner screws located on the larger access panel
•
Completely remove the panel
To clean the filters and heat exchanger:
•
Remove the access panel
•
Slide out the filters that are fitted either side of the heat exchanger as shown.
•
Clean the filters carefully using a vacuum cleaner.
•
Carefully remove any dust from the face of the heat exchanger using a vacuum cleaner.
Never use water or any other fluids to clean the heat exchanger.
•
Return the heat exchanger and filters to their original position.
•
Replace the front cover and ensure it is securely located at the top before tightening all screws.
•
Power to the unit can now be restored.
Filter Replacement
Filters should be replaced annually or after a maximum of 3 cleaning cycles.
Replacement filters are available from Vectaire - call us on +44 (0) 1494 522333 or via
