DUPLEXVENT series appliances have a single-stage filtration system. Appliances in a hygienic version in compliance with
hygienic standard VDI 6022 must have an Class F7 filter fitted on the inlet (applies to outdoor air e1/ODA Class ODA 1 and
ODA 2). When outdoor air is Class 3, a Class F5 filter must be fitted in the duct upstream the outdoor air inlet into the
HVAC unit; alternatively, a Class F5 filter may be installed in the HVAC unit and a Class F7 filter in the duct at the e2/SUP
outlet from the unit. Note: F5 and F7 filters are separately supplied accessories.
Appliances in a hygienic version in compliance with hygienic standard VDI 6022 may be operated only if the use of recirculating
air is suitable for hygienic reasons or the arrangement of operation of the HVAC network ensures positive pressure in the supply
section of the appliance against the extraction section
5.3 Identification of ports, connecting the HVAC duct
●
The versatile design of sizes 1100, 1600, 2600 and 3600 allows adjusting the direction of air flow through the appliance. Identify
and label individual ports using the pictures below (labels are included). Begin by identifying port e1 (ODA) - outdoor air inlet;
continue toward the fan on the same (shorter) side of the unit with exhaust air outlet port i2 (EHA); next is the port with fan on the
opposite side of the unit - supply air outlet e2 (SUP); the last (remaining) port is extract air inlet port i1 (ETA).
Note: Depending on a specific location of the unit proceed clockwise or anticlockwise.
●
Connect the HVAC duct following the design documentation.
●
To prevent injuries caused by the fan wheel, an HVAC duct at least 2 metres long must always be connected to the unit. The
duct must be fastened in such a way that it cannot be removed without tools.
ATTENTION: For the unit to reach performance levels stated by the manufacturer a straight duct at least 1 meter long must be
connected to all outlet ports. The duct connected to inlet ports must be arranged in such a way so as to allow a
uniform flow rate across the entire section of inlet ports.
5.4 Installation steps
●
Before installation remove the wooden transport planks.
●
The versatile design of 1100, 1600, 2600 and 3600 sizes allows mounting the unit under the window or under the ceiling.
●
Fit the appliance in such a way that the prescribed handling spaces are observed:
View from the operator's side - windowsill position
Under-ceiling position
