TA Fast-Fit 4 Prefabricated Solution for Terminal Units
Product Information: TA Fast-Fit 4
The TA Fast-Fit 4 is a prefabricated solution designed for small
terminal units. It is manufactured by IMI Hydronic and comes with
shut-off valves, a drain valve, and a strainer (optional). The
product has female threads and a bypass, and it is available in
different versions depending on the diameter size. It also features
the TA-Modulator/TA-COMPACT-P STAV technology that allows for flow
measurement accuracy.
Product Components:
- Shut-off valve
- Drain valve
- Strainer (optional)
- Female threads
- Bypass
- TA-Modulator/TA-COMPACT-P STAV technology
Product Usage Instructions:
Before installation, it is crucial to follow the instructions
provided in the manual. Also, ensure that the TA Fast-Fit 4
assembly is held only on the indicated places by the wrenches in
the illustration.
Installation:
To ensure flow measurement accuracy, it is essential that the
valve must be installed in a straight run. For this purpose, follow
the installation layout as shown in Figure 1 of the manual. The
piping on the inlet side must be straight and have a minimum length
according to the diagram.
Valve Setting:
The flow regulation is achieved by adjusting the valve setting
until the required flow rate is obtained. The handwheel indicates
the valve setting, and for maximum limit of the valve, use a 3 mm
Allen key, turn the inner spindle clockwise to its end position.
The valves operate from closed to fully open with 4 complete turns
of the handwheel. The handwheel indicates the valve setting by
means of digits appearing in outer (black) and inner (red) windows.
The digit in the outer window indicates the number of full turns,
and the digit in the inner window indicates tenths of a turn.
Pipe Cutting:
After cutting the pipe, ensure that the end is deburred before
fitting it to the valve. Failure to carry out this procedure may
lead to errors in flow measurement accuracy.

manual or visit the official website of IMI Hydronic.

Installation To ensure flow measurement accuracy it is essential that 1 the valve must be installed in a straight run
of pipe of the same nominal size, with the flow arrow on the valve body pointing in the direction of flow. 2 the piping in the inlet side is straight and has a minimum length according to Fig. 1. 3 after cutting the pipe, the end must be deburred before fitting it to the valve. N.B. If using pipes smaller than valve size (also when using KOMBI) contact IMI Hydronic Engineering.
