5.5 Preparing the installation of the ducts

INFORMATION
▪ Flexible ducting with sound insulation is effective to
reduce blowing noises.
▪ When you select installation materials, consider the
required volume of air flow and the acceptable level of noise for that particular installation.
▪ When the return air infiltrates into the ceiling and the
temperature and humidity in the ceiling become too high, insulate the metal parts of the unit.
▪ ONLY use the service hole to access the inside of the
unit.
▪ The sound pressure level is less than 70dBA.
CAUTION
▪ For safety reasons, the required minimum length of the
ducting is 1.5 m. If the ducting is shorter, or if no ducting is installed, then you MUST install grilles in the duct openings or the openings of the unit.
▪ Make sure no wind can blow in the ducting.

2 Pass the metal suspension bracket through the anchor bolt.
3 Secure the anchor bolt with washer and nut.
For VAM350~1000:
Installation tips:
▪ Installing the unit upside down allows for common use of the
inspection hole, reducing the required maintenance space. For example, if 2 units are installed closely together, ONLY 1 inspection hole is required for maintaining or replacing filters, heat exchange elements,…
a Control box
b Maintenance cover
c Inspection hole
▪ When the heat reclaim ventilation unit is installed upside down,
the minimum allowed outdoor air temperature is 5°C. If this CANNOT be guaranteed, you MUST install a heater to heat up the outdoor air to 5°C.
▪ Keep in mind that the ceiling hooks have to be reinstalled when
the heat reclaim ventilation unit is installed upside down. They have to be rotated 180°, so that they are upside down (see the illustration).

▪ The minimum bend radius for flexible ducts is as follows:
(Øduct/2)×1.5
▪ To prevent air leakage, wind aluminium tape around the section
where the duct joints and the ducts are connected.
▪ Install the opening of the supply air as far as possible from the
opening of the return air.
▪ Use ducts with a diameter that fit the unit model. See the data
book.
▪ Install the two outdoor ducts with down slope (slope ratio of 1 in
50 or more) to prevent entry of rain water. Also provide insulation for both ducts, to prevent dew formation. (Material: 25 mm thick glass wool)
▪ If the level of temperature and humidity inside the ceiling is always
high, install ventilation inside the ceiling.
▪ Insulate the duct and the wall electrically when a metal duct has to
penetrate the metal lattice and wire lattice or the metal lining of a wooden structure wall.
▪ Install the ducts in a manner that the wind CANNOT blow inside
the ducting.
VAM350~1000
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable legislation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on the site and all electrical
construction MUST comply with the applicable legislation.

6.5.1 Precautions when connecting electrical wiring

DANGER: RISK OF ELECTROCUTION
WARNING
If NOT factory installed, a main switch or other means for disconnection, having a contact separation in all poles providing full disconnection under overvoltage category III condition, MUST be installed in the fixed wiring.
WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable
legislation.
▪ All field wiring MUST be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do NOT come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.
▪ Make sure to install earth wiring. Do NOT earth the unit
to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.
▪ Make sure to use a dedicated power circuit. NEVER
use a power supply shared by another appliance.
▪ Make sure to install the required fuses or circuit
breakers.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electric shock or fire.
▪ When installing the earth leakage protector, make sure
it is compatible with the inverter (resistant to high frequency electric noise) to avoid unnecessary opening of the earth leakage protector.
