Make sure ventilation is adequate to maintain recommended operating temperature.
Keep a minimum distance of 5 cm between the cooling fans and surrounding items
(e.g., housing, walls, etc.), or else install an external automatic ventilation system.
Check fans regularly for dust/dirt. Clean fan guard grills if necessary to avoid a re-
duction of ventilation.
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.
The ON/OFF-switches are located at the terminal box. At first, switch on the rotary
vane pump (backing pump), then switch on the diffusion pump. The diffusion pump
can be switched on only if the backing pump has been switched on.
Comply with all applicable and relevant safety requirements (regulations and
guidelines). Implement the required actions and adopt suitable safety mea-
sures.
Ambient conditions
•
Adopt suitable measures in case of differences from recommended conditions,
e.g., using the equipment outdoors, installation in higher altitudes, conductive
pollution or external condensation on the pump.
•
Do not operate this product near flames.
To the best of our knowledge the equipment is in compliance with the requirements
of the applicable EC-directives and harmonized standards (see "Declaration of Con-
formity") with regard to design, type and model. Directive EN 61010-1 gives in detail
