The feed water supplied to the liquid ring vacuum pump must
meet the following requirements:

♦ Water temperature: shall not exceed 59°F (15°C).
Note:
The use of hard water in the vacuum pump may invalidate the
warranty for the vacuum pump, since it can cause blocking of
the rotor, which can damage the pump.
