match in voltage, phase, and frequency.
• Ensure that the coolant outlet pipe is always free and
that it cannot get blocked. If installing an optional cool-
ant valve, it must always be in the supply line of the
exhaust waste vapor condenser.
Make sure ventilation is adequate to maintain recommend-
ed operating temperature. Keep a minimum distance of
2 in (5 cm) between the cooling fan and surrounding items
(e.g., housing, walls, etc.), or else install an external au-
tomatic ventilation system. Do not place the pump on soft
surfaces (e.g., rubber foam) during operation. This may
reduce the air circulation in the pump housing and affect
the fans’ cooling effect. Check fans regularly for dust/dirt.
Clean fan guard grills if necessary to avoid a reduction of
ventilation.
Position the CVC 3000 controller and its vacuum line in
such a way that condensate cannot flow towards the pres-
sure transducer.
Use only hoses at the inlet and outlet of the pump with
an inner diameter at least as large as the diameter of the
pump’s tubing (to avoid overpressure at the outlet, and
reduction of pumping speed at the inlet).
Allow the equipment to equilibrate to ambient temperature
if you bring it from cold environment into a room prior to
operation. Notice if there is water condensation on cold
surfaces.
Secure coolant hoses at the hose nozzles (e.g., with hose
clamp) to prevent their accidental slipping.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re-
quired actions and adopt suitable safety measures.
