1.0 Installation

1.1 Product description

Lindab’s high performance supply air beam Premax can be used for cooling, heating

and ventilation. Water valves, actuators, Regula Secura, Regula Combi and Regula

Connect can all be built into the Premax beam.

1.2 Handling

The beam must be handled with care, ensuring that the beam does not sustain dents,

scratches or bends during installation.

Always seek to lift the beam at multiple points.

– Do not lift in pipes

– Do not lift in edges

– Each beam is equipped with protective ﬁlm to avoid any damage during transport

and handling at building site. The ﬁlm needs to be removed before commissioning

the products.

1.3 Mounting instruction

– Please visit www.lindqst.com

• Select Documentation Finder

• Select “Premax”

• Select “Mounting”

1.4 Air connection installation

The primary air supply should be connected with instructions from a ventilation spe-

cialist. Lindab’s chilled beams can beneﬁcially be used together with Lindab’s Safe®

duct systems.

1.5 Connection description water

Flow indication arrows are shown on the inlet and return pipes in order to assist the

installer. If the beam has been ordered with integrated valves, a special direction

of the ﬂow must be upheld to ensure correct ﬂow through the thermostatic valve. If

the beam has been delivered without integrated valves, the ﬂow can be reversed,

depending on the location of the retroﬁtted valve. Please note the ﬂow direction indi-

cator on the valve to insure correct installation in relation to the desired ﬂow.

1.5.1 Push-on ﬁttings

– Please ensure that all pipes and ﬁttings are undamaged, as even small dents and

scratches potentially pose a risk of leakage in the system. Always remember to do

a pressure test after assembly of the pipe work.

– Both ﬂow and return pipe is covered by a plastic or rubber protection cover,

which should be removed before installation.

After removing the protection cover, make sure that the pipe is intact and undam-

aged, especially at the pipe end. Crocked or in other ways imperfect pipe ends will

result in leaks. Deburr the pipe on the inside and the outside, using a deburring tool

before installation

– Mount a push-on ﬁtting to the pipe. Make sure to press the ﬁtting all the way onto

the pipe. Consult the installation guide for the speciﬁc ﬁtting for further details on

proper installation.

Push-on valve

Notice! The connection pipes are internally soft-welded why it’s not allowed to

solder the beam to the pipes.

1.5.2 Compression ﬁtting

– Please ensure that all pipes and ﬁttings are undamaged, as even small dents and

scratches potentially pose a risk of leakage in the system. Always remember to do

a pressure test after assembly of the pipe work.

– While mounting a compression ﬁtting, the pipe will be exposed to a big amount

of force, creating a risk of crushing the pipe. To ensure that the pipe won’t be

crushed when mounting the compression ﬁtting, a copper insert should be

inserted into the pipe.

– Both ﬂow and return pipe is covered by a plastic or rubber protection cover

during transport, which must be removed before installation.

– After removing the protection cover, make sure that the pipe is intact and undam-

aged, especially at the pipe end. Crocked or in other ways imperfect pipe ends

will result in leaks. Deburr the pipe on the inside and the outside, using a deburr-

ing tool before installation

– The copper insert should be placed inside the pipe on the beam. Always support

the copper pipe coil when inserting the copper insert into position.

– Mount a compression coupling and/or a valve to the pipe. Don’t stress the nut too

much, since this may crush the pipe.

Notice! The connection pipes are internally soft-welded why it’s not allowed to solder

the beam to the pipes.

1.5.3 Flex hoses

Our ﬂexible hoses can be used with both compression and Tectite ﬁtting. We recom-

mend using Tectite ﬁttings, for easier and faster mounting.

– Please ensure that all pipes and ﬁttings are undamaged, as even small dents and

scratches potentially pose a risk of leakage in the system. Always remember to do

a pressure test after assembly of the pipe work.

– Both ﬂow and return pipe is covered by a plastic or rubber protection cover,

which should be removed before installation.

that the ﬂexible hose is pushed fully into the ﬁtting. Consult the installation guide

for the speciﬁc ﬁtting for further details on proper installation.

2.0 Commissioning

2.1 Product labeling

Fig.1: Label location exterior (water connection) Fig.2: Label location interior (battery end).

On the label you’ll ﬁnd:

– Order: Order identiﬁcation number.

– Pos: Order position.

– Product: Product conﬁguration.

– Project: Project name.

– Mark: Marking noted on order.

– Nozzles: Number of nozzles.

– Plugs: Number of plugged nozzles.

– Product ID: Product number.

– Sign: To be signed when checked and commissioned on site.

2.2 Measure air pressure and calculating the airﬂow.

Before calculating the airﬂow, the static nozzle pressure must ﬁrst be measured. The

static nozzle pressure is the air pressure available at the nozzles.

2.2.1 Measure the static nozzle pressure.

– To measure the air pressure, a manometer, analog or digital (such as the Lindab

PC410) will be needed.

– Insert the measuring tube onto the specialized measuring nozzle

– Read off the static nozzle pressure from the manometer

2.2.2 Calculating the airﬂow

– After measuring the static nozzle pressure, read the setting of the four pins in the

corners to ﬁnd the mean value of the pins.

– Locate the diagram on the faceplate or see diagram 1-2, and use the static nozzle

pressure and the mean value of the pins to ﬁnd the current airﬂow.

2.3 Changing the airﬂow

– Measure the static nozzle pressure

– Locate the air pressure/airﬂow diagram on the faceplate, or see diagram 1-2.

– Find the mean value of the four pins to reach the desired airﬂow, in the diagram

on the faceplate. Use the static nozzle pressure and the desired airﬂow to ﬁnd the

mean value of the four pins.

– Adjust the four pins in the corners, so the mean value of the pins will correspond

with the mean value found in the diagram.

– Example: Pin setting: 6+6+8+8 = 28 / 4 = mean value 7.

2.4 Changing the air pattern (with plus feature AirGuide)

ONLY POSSIBLE IF THE BEAM WAS DELIVERED WITH AIRGUIDE

– Press the Airguide retaining clip to retract the clip from the Airguide deﬂector.

– Align the Airguide deﬂector in the desired position.

– Realease the Airguide retaining in the new position.
