T series convectors are our smallest units designed for efficient heating. They are a great choice for use with heat pumps due to efficient heat transfer even at low heating medium temperatures

Quiet operation

T convectors show low noise values in their category. At low and medium speeds, noise does not exceed the common noise background. The microprocessor control unit takes care of the smooth operation of the fan

Compatibility with control systems

The control unit also offers a wide range of settings, allowing the optimal convector control by various types of thermostats, BMS or Smart Home systems.

Ecological and economic solution

Due to the low volume of water in the exchanger and the high heat transfer efficiency, are the T convectors valuable for environmentally friendly and energy efficient heating. Low water volume minimizes losses in distribution and reduces the reaction times of the system.

A wide range of accessories

For your comfort, the T series convectors can be ordered with the complete accessories needed for easy installation and a reliable function. An overview of available accessories can be found on the MINIB website.

ORIENTATION AND CONNECTION

When ordering T series convectors, it is necessary to specify the orientation of the convector (left/right) and the water connection (straight/corneous).

Convector as the main source of heating

If the convector works as the main heat source we recommend to install the convector with the exchanger to the room side.

Convector as an additional source of heatling

If the convector is used as an additional heat source, which prevents the condensation of the window, install the convector with the heat exchanger towards the window.

CONNECTION OPENINGS

The convector is supplied with pre-cut holes for all connection directions and all variants of connection accessories. Simply push-out the holes according to the connection direction you have chosen. The positions of the connection openings for the individual dimensions of the convector are shown in the drawings. The openings are placed symmetrically according to the longitudinal and transverse axes of the convector.

BEFORE INSTALLATION

Select the correct convector position. Consult the convector position with an expert or your designer: if the convector is intended to be the main source of heat, it must be placed with the heat exchanger facing the room (PIC. 3), if the convector serves as an additional source of heat (as a thermal barrier), it is placed with the heat exchanger facing the window (PIC. 4).

PIC. 3: Main source of heat	PIC. 4: Additional source of heat

In case of a convector with a fan, always verify the regulation method of the convector. The method of regulation is stated on each technical sheet of the convector.

Installation Space

MINIB,a.s. recommends leaving sufficient space for convector installation in the structural opening. For installation in older floors, floors after renovation, or whenever sufficient space is not available, the dimensions of the installation opening should be equal to the convector height + at least 20 mm. The width and/or length (if only 1 convector is being installed) of the installation opening should correspond to the convector width (length) + at least 60 mm – see PIC. 5. Clearance around the convector should provide enough space for the water connection, electrical connections and for convector embedding in concrete. For new floors, MINIB, a.s. recommends at least +100 mm of free space around the convector; the height remains the same (H + at least 20 mm).

Principles before installing the floor convector

MINIB floor convectors are designed for installation in solid or hollow floors where certain principles have to be applied.

Convectors, which are designed, for wet environment or for after-cooling are equipped with a Ø 18 x 23 mm drainage pipe. You will probably have to connect a hose leading to the sewer system, sump or another location.

Principles of installation in HOLLOW floor

Use of reinforcement - U-channels When installing a convector in a hollow floor, in particular where more intensive traffic is expected (e.g., public buildings and office spaces) hollow floor U-channels must be used outside the convector body, which help ensure shape stability (PIC. 6).

PIC. 6: Hollow floor – U-channel for floor convector

Use of thermal-insulations Use thermal insulation depending on the type and nature of the floor, especially when installed in parquet, floating or all-wood floors. Thermal insulation is to be applied on the outer surface of the metal body of the convector (PIC. 7). If the heat exchanger is located at one side of the convector, it is sufficient for the insulation to be applied only on the heat exchanger side. If the heat exchanger is placed symmetrically in the convector it is advisable to apply insulation on both sides. The insulation protects the finished floor from the direct heat of the convector. If you do not use this insulation there is a risk of quick drying out of the floor (parquet), leading to unstable joints between the wooden blocks. This risk is particularly high in hollow floors where the heat is also transmitted through the metal body of the convector to the floor cavity.

PIC. 7: Hollow floor – thermal insulation for floor convector

Use of anti-vibration sheets For hollow floors MINIB,a.s. recommends to use anti-vibration sheets, to reduce the impact noise and/or any (fan) vibrations (PIC. 8). ::: alert warning::: For convectors with fan it is necessary to use anti-vibration sheet in hollow floors to dampen vibrations! :::

PIC. 8: Hollow floor – anti-vibration sheets for floor convector

The floor must be aligned as closely as possible with the convector perimeter. The expansion joint must be filled, for example with cork lining or silicone. This will prevent horizontal movement of the convector during load impact.

Principles of installation in SOLID floor

Always make sure the convector is well embedded in concrete to prevent air bubbles under the convector bottom which could cause increased transmission of the impact noise and vibrations (from the fans).

For installation in solid floors it is not necessary to use U-channels. Consider the use of thermal insulation, especially for wooden floors.

INSTALLATION

A correctly installed convector is in horizontal position and the top edges of the trough are not damaged or bent in order to ensure correct functionality of the walk-on grille; has a standard frame aligned with the final floor.

It is recommended that the top convector cover (fiberboard) be left in place during concrete pouring to prevent the contamination of the convector interior.

In case of installation to the solid floor, before pouring concrete thoroughly seal (with adhesive tape) all holes (e.g., unused prepared attachment holes and installation braces) to prevent concrete from entering the convector trough. During the concrete pouring process, the convector must be fixed in the floor with anchoring screws to prevent vertical movement of the convector after cast in concrete or another suitable material. A vertical load may also be applied to the convector during the concrete pouring process.

Installation in the hollow floor is solved individually according to the type of floor.

Installation of convectors with and without fan with standard construction

1. Insert 4 adjustment screws (6 screws for lengths over 2000 mm)

PIC. 9

2. Place the convector in the structural opening, mark the holes for mounting the feet, and remove the convector.

PIC. 10

3. Drill the marked holes (Ø 6 mm, depth 30-35 mm). Insert screw anchors in the holes.

PIC. 11

4. Clear the perforated plugs of the holes for heating water connection.

PIC. 12

5. If necessary, install U-channel reinforcements, thermal insulation or anti-vibration foils.
6. Place the convector in the structural opening and install the heating water pipes.

PIC. 13

7. Fix the convector using the attachment feet in the prepared screw anchors. Fix the feet using quick-hardening concrete.

PIC. 14

8. If the convector is equipped with a drainage pipe connect it to the prepared drain.

PIC. 15 Drainage pipe can be located on a side of the convector other than the side shown on the picture, depending on convector type.

9. In case of a convector with a fan, install the power supply cable for the electronics in the placed convector. For safety reasons check whether the supply cable is live.

PIC. 16

10. Align the convector (with frame attached) using the adjustment bolts. Set the final height so that the convector frame is aligned with the inished floor.

PIC. 17

11. Connect the inlet and outlet pipes. Perform final alignment according to PIC. 18.

PIC. 18

12. In case of a convector with a fan connect the convector control unit using the connecting, control instructions, and follow the wiring diagrams in the instructions depending on the control type selected.

PIC. 19

13. Make sure that all openings inside the trough are sealed so that the convector interior is not contaminated during the concrete pouring process! Install struts of the convector trough and wooden braces together with fiberboard cover.

PIC. 20

14. Pour concrete slurry to at least 1/3 of the convector height in order to minimize the impact noise transmission. In the case of poor embedding of the bottom in concrete the convector with fan might resonate!

PIC. 21

15. The entire space around the convector must be subsequently filled with normal concrete up to the final height of the unfinished floor. The convector is now set in the unfinished floor, which is ready for floor finish installation (parquet, tiles, etc.)

PIC. 22

PIC. 23 A correctly installed convector has a standard frame aligned with the floor finish.

Installation of convectors without a fan with universal construction

1. Install adjusting screws - height adjustment by adjusting screws is done from inside the convector.

PIC. 24

2. Select anchor leg position.

PIC. 25: - Convector anchor leg position variants

3. Place the anchor legs to the holes for attaching the legs to the convector. Screw the leg to the convector.

PIC. 26

CONNECTION OF THE FITTINGS

The heating or cooling system is connected using the connection accessories. The type of fittings and hoses varies according to the type and purpose of the convector.

Connect individual inlet and outlet valves.

Water inlet: a ball or screw connection or a thermostatic valve is connected to the inlet. If thermostatic valves are used observe the flow direction of the valve and leave sufficient space for the valve with the given throughput. The angular screw fitting or angular thermostatic valve is connected to the inlet for connections from the window or room side.

Outlet (return pipe): The screw fi tting is always connected to the return pipe. In some cases, it may be necessary to switch the hot water inlet and outlet depending on the space required for thermostatic valve installation; however, fittings are always installed as described above.

Install sealing between each joint.

In case the water connection set includes flexi hoses, use the flexible stainless steel hoses (bellows hose) for connecting the heat exchanger. An example of direct and corner connection can be found on the picture 31, 32 and 33.

The stainless steel hoses are designed to withstand a maximum pressure of 1000 kPa. The hoses must not be stretched, subjected to tensile stress, or otherwise deformed.
