· 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 locat-
ed 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 connec-
tion pipes.
· Before welding/soldering the pipes, ensure that the direction of
flow through the valve is correct.
· The pipes must be welded/soldered with care. To avoid dirt
and the formation of scale (oxide), inert gas is recommended
for welding/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 welding/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.
The valve is supplied complete with Mounting Instructions 74 319 0707 0.
