1.4 Function of the unit
The principle of heat recovery in the TX3100A is based on the rotating heat exchanger (B).
The exhaust fan (A) draws the warm room air through the funnel of the inlet ring(D),
through half of the heat exchanger (B), and send it through the exhaust cap (F).
Simultaneously the inlet fan will (C) draws air through the inlet cap(G), sending it through
the other half of the heat exchanger. The heated fresh air is sent through the inlet ring (E)
and distributed evenly in the room.
One half of the rotating heat exchanger will always be in the hot airflow from the exhaust
air. When the heated material in the heat exchanger is in the cool flow of the inlet air, it will
transfer heat from the material to the fresh supply air.
The process is regenerative as the heat exchanger rotates at a constant low speed.

install mounting stud extensions with the mounting studs. With the mounting stud
extensions the placement can be adjusted additional 300 mm vertically.
The mounting stud extensions are attached to the
TX3100A unit using the long M8 bolts and washers
with which the mounting studs were attached by
default. The mounting studs are attached to the
mounting stud extensions using the short M8 bolts and
washers that comes with the mounting stud
extensions.

2.3 Placement
TX 3100A is intended for installation through the roof. The unit can be placed in roofs with
inclines ranging from 0 to 45 degrees. TX3100A is available with two types of mounting
brackets;
Standard mounting brackets place the unit with the inspection hatch inside the building
while adjustable mounting brackets place the unit with the inspection hatch outside the
building.
2.4 Template
It is recommended to create a template from the chart below based on incline of the roof.
The illustration is shown with an incline of 25°
0° = Ø 870 mm
5° = 870 x 880 mm
10° = 870 x 890 mm
15° = 870 x 900 mm
20° = 870 x 930 mm
25° = 870 x 970 mm
30° = 870 x 1010 mm
35° = 870 x 1070 mm
40° = 870 x 1140 mm
45° = 870 x 1240 mm

2.5 Installing the unit(standard mounting brackets)
If the unit is installed by hoisting it up through the roof, the following components must be
temporarily removed for installing the unit:
•the 2 mounting studs
If the unit is to be installed by lowering it down through the roof,
the following components must be temporarily removed for
installing the unit:
•The 2 electrical boxes. The electrical wires that are
connected to the boxes are long enough, so that they don’t
need to be disconnected while installing the unit.
•The 4 wire brackets
The placement of the unit can be adjusted vertically through the
placement of the mounting studs as shown in 2.1 Dimensions and
2.2 Mounting stud extensions.
The placement and center of the unit is marked through

According to the placement of the unit it is measured where
the two standard mounting brackets should be installed with
a distance between them of 1000 mm, so that the unit is
placed equally distanced from both.
The standard mounting brackets are designed for a distance
between the purlins of up to 1070 mm. The end pieces are
fastened to the purlins using the 12 included Ø8 mm wood
screws.
The center pipes are adjusted so that the fork brackets are
horizontally aligned and so that their co-centric line is in the
center of the hole. The center pipes are fixed in place through
the endpieces with the 8 Ø6,3 mm self-drilling screws.
The unit is hoisted in place with a crane.
If the 2 mounting studs were temporarily removed for installing,
they are now re-attached to the unit.
When choosing installation with standard
mounting brackets the unit must be placed
with the service hatch facing towards the
ridge of the roof.
If the 2 electrical boxes has been detached
for installing the unit, pay attention to them so
that they are not stuck and damaged during
the use of a crane with the unit.

shaped brackets of the standard mounting brackets. It is checked that the unit is plumb.
If the 4 wire brackets were temporarily removed for installing the unit, they are now re-
attached to the unit.
The remaining included 4 wire brackets are attached to the purlins or battens.
The included wires and wire tensioners are now attached between the 4 wire brackets on
the unit and the 4 wire brackets on purlins or battens. The wire tensioners are tightened so
that the unit is fixed and plumb.
With the unit and wires installed, fixed and adjusted the 2
electrical boxes can be re-attached to the unit.

In the center of the soft cover a hole is cut. It is recommended to use the template from
2.4 Template as reference. It must be taken into consideration when cutting the hole that
the soft cover should be placed under either overlying roof plate(s) or the ridge of the roof
with an overlap of minimum 100 mm.
The overlying roof plate(s) the ridge of the roof is lifted to put the soft cover beneath it. The
soft cover is fastened with the included Ø5,5 mm self-drilling screws, up to 50 screws, with
a distance between them of approximately 200 mm or as required to ensure proper seal
with the roof.
A joint of silicone rubber grout is laid where the softcover meets the
unit. The soft cover is pressed against the unit by hand to ensure
seal between the soft cover and unit.
The hole in the soft cover is cut with a
diameter approximately 100mm smaller
than the hole in the roof to ensure proper
seal around the unit

The attachment of trapezoidal sheets should be reinforced, either with trapezoidal brackets
or planned and constructed as part of the roof's structure.
With the desired placement and center mark of the unit as reference(optionally using the
template from 2.4 Template) it is determined where the 2 trapezoidal brackets should be
placed. They must be placed with a distance to each other of 1400-1600 mm. They must
be placed in an equal distance from the unit and so that they attach to first trapezoidal
plate profile that will not be cut when making the hole for the
unit. 4 M8 popnuts is installed in the trapezoidal profile
corresponding to the final placement of each end piece.
The two trapezoidal brackets are fixed to the trapezoidal profils
