90°
· The refrigerant valves can be mounted in any
orientation, but upright mounting is preferable.
· The pipes should be fitted such that the alignment does
not distort the valve connections. The valve body
should be fixed such 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
· Port 2 must be sealed off when the valve is used in a
straight-through application (1 ® 3).
· The valve body and the connected pipework should be
lagged.
·
The actuator must not be lagged.
