1.2 Intended use

There is a risk of injury or death to the user or

others, or of damage to the product and other

property in the event of improper use or use

for which it is not intended.

The product is only intended for aerating and

ventilating living areas. If the product is oper-

ated with a heat production source, the heat

production source must be room-sealed. The

remote control must only be used to control

the product. The product must only be oper-

ated when the filters are inserted.

The product is not suitable for aerating and

ventilating swimming pool systems. Due to

the high level of exposure to dust, the product

must not be operated during the construction

phase.

Intended use includes the following:

–observance of accompanying operating,

installation and servicing instructions for

the product and any other system compon-

ents

–compliance with all inspection and main-

tenance conditions listed in the instruc-

tions.

Any other use that is not specified in these

instructions, or use beyond that specified in

this document shall be considered improper

use. Any direct commercial or industrial use

is also deemed to be improper.

4.3 Observing the requirements for the

installation site

4.3.1 Observing the requirements for the

product's installation site

The product can be installed in dwellings, cellar spaces, stor-

age or utility rooms, and in attics. The product is wall-moun-

ted only.

▶Observe the current applicable national construction reg-

ulations.

▶Ensure that the installation site is dry and is frost-proof

throughout.

▶Ensure that the installation site is aerated and ventilated.

▶Install the supply air pipeline so that there is sufficient

distance to the exit air pipeline, exhaust air pipeline and

outflow purging.

▶Check the load-bearing capacity of the wall.

–Load-bearing capacity: ≥41 kg

▶Check whether the supplied fixing elements are sufficient

for the selected installation site.

▶Ensure that the installation site is not located higher than

max. 2000 metres above sea level.

Minimum clearances and installation clearances

400

300

400

▶Observe the minimum clearances and installation clear-

ances.

▶Plan sufficient space for installing the ventilation system.

▶In order to minimise pressure losses, ensure that the dis-

tances between the header line of the ventilation system

and the product are as short as possible.

▶After installation, ensure that the pipelines and the ventil-

ation system are easily accessible.

▶Ensure that the mains plug/circuit breaker (depending on

the country) is always accessible after the installation.

▶Ensure that there is sufficient space to install the con-

densate siphon and condensate drain pipework.

4.3.2 Observing the requirements for the

installation site of the remote control (step

switch/control)

▶Ensure that the remote control is always accessible at

the installation site.

▶Ensure that there is sufficient space to install and operate

the remote control.

4.3.3 Observe the requirements for silencers and

for installing ducts and the product

If the opening for the exit air pipeline is too close to the inlet

opening of the outside air pipeline, the exit air can recircu-

late.

▶Prevent exit air from being sucked in through the outside

air opening, supply air from being sucked in through the

exhaust air opening, and transfer air from being sucked

in directly through leaks/cable feedthroughs.

▶If required, connect the product to the pipelines using a

sound-absorbing hose in order to minimise noise pollu-

tion caused by structure-borne noise.

▶Install silencers in order to minimise noise pollution via

the duct system.

▶If you install the product in an attic, select an installation

site that is not above living spaces.

8Installation and maintenance instructions recoVAIR 0020159949_07

▶If particular acoustic requirements are in place at the

installation site, you should take corresponding on-site

measures to prevent noise.

4.4 Installing the product on the wall

min. 1120

Caution.

Risk of material damage caused by con-

densate.

If the condensate cannot drain from the

product, this may damage the product and

condensate may leak out of the product and

onto the floor.

▶Install the fixing bracket with the correct

horizontal and vertical alignment.

1. Drill the holes for the fixing screws.

–Installation height of the fixing bracket: ≥1,120 mm

2. Insert the rawl plugs into the drilled holes.

3. Screw the fixing bracket to the wall, tared.

–Installation position: Horizontal

–Taring the fixing bracket: Using the slotted holes in

the fixing bracket

–Spirit level

Danger!

Risk of injury caused by a heavy weight

when mounting the product.

The product weighs 41 kg. If you are mount-

ing the product, the product may easily slide

out of your hands and cause injuries.

▶Make sure that the product is mounted by

at least two people.

4. Position the product on the fixing bracket and mount the

product.

4.5 Connecting the condensate siphon/dry

siphon and condensate drain pipework

1. Connect the condensate siphon/dry siphon to the

product (→Installation instructions for the condensate

siphon/dry siphon, accessories).

–Condensate discharge pipe downward gradient

(descending from the product): > 5°

min. 20

Danger!

Risk of damage to health caused by incor-

rectly connected condensate drain pipe-

work!

In the interests of hygiene, the condensate

drain pipework must not be directly connec-

ted to the waste-water piping.

▶Connect the condensate discharge to the

second siphon.

Set-up 4

0020159949_07 recoVAIR Installation and maintenance instructions 9

Caution.

Risk of material damage caused by con-

densate.

If a condensate discharge pipe has been con-

nected incorrectly, a build-up of condensate

and uncontrolled condensate drainage may

damage the product. Furthermore, the con-

densate may leak out of the product and onto

the floor.

▶Install a drip distance of min. 20 mm

between the outlet for the condensate

drain pipework and the second siphon.

▶Note the downward gradient for the con-

densate discharge pipe (> 5°).

2. Connect the condensate drain pipework to the second

siphon while taking into consideration the drip distance

(1).

–Drip distance: ≥20 mm

3. Fill the condensate siphon/dry siphon with water.

4.6 Connecting the pipelines

1. Check the pipelines for coarse dirt.

Coarse dirt: Available

▶Clean the pipelines.

2. Route the pipelines in accordance with the manufac-

turer's specifications and applicable regulations for the

product.

–Diameter of pipelines: ≥150 mm

–Exit air lines: Continuous downward gradient to the

unit/Using the condensate drain pipework, if neces-

sary

3. Install the silencer in the supply, exit and outside air

lines.

4. Insulate all of the pipelines in accordance with the ap-

plicable regulations.

Note

Supply and exhaust air lines too, when rout-

ing through unheated rooms.

5. Seal the outside and exit air lines so that they are va-

pour-diffusion-tight.

1 Exit air connection

2 Supply air connection

3 Exhaust air connection

4 Outside air connection

6. Remove the sealing caps from the product connections.

7. Connect the pipelines to the product.

Caution.

Risk of material damage caused by a

missing seal.

If the pipelines are not connected to the

product in way that is vapour-diffusion-tight,

condensate may form and damage the

product.

▶Seal all of the connections for the

pipelines to each other and on the

product, so that they are vapour-diffusion-

tight.

▶Use suitable accessories and sealant.

8. Seal all of the product connections so that they are va-

pour-diffusion-tight.

–Suitable vapour-diffusion-tight adhesive tape
