Damage to the Floway dual-ow air handling unit will be disregarded in case of failure to follow the instructions in this
document.
Each unit has a name plate bearing an identication number. This number must be quoted in all correspondence.
In accordance with Article 133-3 of the French Code of Commerce, the recipient is entirely responsible for checking the condition
of the goods received. In the event of missing items, the customer must provide the exact number of parcels delivered. Any damaged
or missing items must be specied on the delivery note in the presence of the driver before signing the delivery note. These
comments must be conrmed to the carrier by registered letter within 3 business days. The comments "conditional" and "pending
unwrapping" shall have no value. The customer must unwrap the goods in the presence of the driver. Damage/shortages must be
noted at time of delivery and described in detail.

FLOWAY “Classic PHE”, “Classic RHE/RHE-Z” and “Vertical PHE”
• The 3 sizes of the "Vertical PHE" model and the 1000 size of the "Classic PHE" and "Classic RHE/RHE-Z" models are packaged
units, delivered mounted on feet.
• Sizes > 1000 m³/h for the "Classic PHE" and "Classic RHE/RHE-Z" models are multi-block units, delivered assembled. The
blocks can be split in order to facilitate their passage through doorways (see splitting procedure in the HANDLING part).
• Sizes 10000 and 15000 of the RHE-Z model are delivered in 2 blocks. You are responsible for assembling these yourself on
site. Quick connectors enable the electrics for these blocks to be connected quickly and easily.
FLOWAY EN-4

3 - HANDLING
The unit can be handled by slings, lifting beam or stacker.
In all cases, the lifting point has to be at the base of the unit. For packaged units or assembled multi-block units, the centre of
gravity is at the centre of the unit.
This operation will be performed by qualied personnel.
The unit must be handled with care, and only in the horizontal
position. If the unit is handled by a lifting beam + slings, tubes
need to be placed in the holes provided in the support feet.
Ensure that the crane hook adapter is large enough to prevent
the belts applying any pressure to the AHU casing.
Furthermore, ensure that the steel tubes are secured to
prevent any movement.
If the above-mentioned lifting methods cannot be used, the unit
may be lifted using a forklift truck, taking great care not to dent
the lower panel (use forks of a su󰀩cient length).
Follow the applicable handling rules.

3 Disconnect the electrical connectors on the control and disconnect switch.
4 You can now separate the blocks.
Note: Follow the procedure in reverse to re-couple the blocks, particularly for the RHE Z10000 & 15000.
When uncoupling the blocks, ensure that the 18X10 PVC gasket located between the blocks remains correctly
in place to guarantee a perfect seal. If necessary, t one.
NB: if there is a roof, remove it rst in accordance with the instructions given on the roof tting plan (see technical specications).
FLOWAY “Classic PHE”, “Classic RHE/RHE-Z” and “Vertical PHE” models
These models are placed directly on a at, smooth oor. The atness value must be the best possible, around one per thousand.
Under normal conditions of use, there is no need to x the unit to the oor.
The unit's support feet must be standing fully on their contact surface. It is important to allow su󰀩cient service space to facilitate
maintenance operations.

1000 - 1100 ppm Tolerable level for enclosed spaces
5000 ppm Upper limit for 8 hours of exposure
* CO2sensor (sensor in duct): refer to the attached supplier manual
Duct pressure sensor
The optional constant pressure mode is available in two versions
-Constant pressure on intake: the air intake fan is controlled to maintain the supply air duct pressure. The extraction fan copies
the intake air ow. It is possible to create an o󰀨set between these two ow rates by conguring the M factor between 0.5 and
1.5 (see control manual).
-Constant pressure on both ow rates: each fan is controlled independently according to the pressure of the associated duct
network. The intake and exhaust ow rates are not connected.
Two pressure values can be congured: Nominal pressure and Reduced pressure.
The duct pressure sensor must be positioned on the duct
network at a distance of D = 2 Dh (hydraulic Ø)
• If the duct is circular, Dh = Ø of the duct
• If the duct is rectangular DH
To guarantee the duct pressure sensor works correctly,
an autozero must be performed on system start-up.
To do this, power up the sensor, disconnect the pipes from the 2 pressure tappings, marking their positions, and press the
"autozero" button located inside the unit. Ret the two pressure tubes in their respective positions.
This autozero should be checked once a year.

The installation of the equipment must comply with the regulations and standards of the recipient country
The additional box must be positioned in the duct so that the temperature sensor is on the downstream side
(air supply)
Special recommendations:
• Connections must not place mechanical stresses on the unit.
• Keep all inspection doors closed while the unit is operating
• If tted outdoors (Classic PHE and Classic RHE/RHE-Z models only), the units must be installed so as to withstand the climatic
conditions in the installation location (risk of snow: height from ground/risk of wind: suitable mountings, swan-neck type
electrical connection to the unit etc.).
Flexible sleeve
Ensure all electrical components are earthed.
5.1 - OUTDOOR INSTALLATION ("Classic PHE" and "Classic RHE/RHE-Z" model only)
The installation of a "Floway" dual-ow unit outdoors requires a roof and a canopy to be tted; these are usually supplied mounted*
and adapted to suit each conguration.
(* Supplied in kit form if delivery of the elements assembled is not possible)
Fitting the roofs:
The roofs for Floway units are designed to provide su󰀩cient protection against adverse weather conditions, as they overlap the
edge of the unit by 80 mm.
Fitting procedure:
1 Fix the foam seal along the length of the unit. (50 x 20 foam seal).
