5.4 Expansion joints
Alfa Laval recommends the installation of expan-
sion joints on both inlet and outlet connections.
Expansion joints are elastic elements which, if
properly installed, absorb the thermal expan-
sions of the tubing. Expansion joints are also
helpful in order to reduce vibrations in the piping.
Picture shows an installation example using
threaded bar, nut, grower washer, washer and
locknut (not supplied).
This way vibration dampers can be used to
make the cooler level adjusting the locknut. This
is particularly useful with long units or irregular
basement.
5.5 Switch on/off (option SW)
If switch on/off (SW) is selected, the default positioning is for horizontal airflow installation.
The cover design is such that it can be used both for horizontal and vertical airflow installation.
To adjust the switch positioning to the actual positioning on site: unscrew the cover fixing screws,
turn it as shown and replace fixing screws.
