• The refrigerant valves can be mounted in any orientation, but
upright mounting is preferable.
• Arrange the pipework in such a way that the valve is not
located at a low point in the plant where oil can collect.
• The pipes should be fitted in such a way that the alignment
does not distort the valve connections. Fix the valve body so
that that it cannot vibrate. Vibration can lead to burst
connection pipes.
• Before soldering the pipes, ensure that the direction of flow
through the valve is correct.
• The pipes must be soldered with care. To avoid dirt and the
formation of scale (oxide), inert gas is recommended for
soldering.

• The flame should be large enough to ensure that the junction
heats up quickly and the valve does not get too hot.
• The flame should be directed away from the valve.
• During soldering, cool the valve with a wet cloth, for example,
to ensure that it does not become too hot.
• The valve body and the connected pipework should be
lagged.
• The actuator must not be lagged.
