• Ensure that no foreign objects can be drawn into the
pump.
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment
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 auto-
matic ventilation system. Clean ventilation slots if neces-
sary to avoid a reduction of ventilation.
Do not place the pumping unit on soft surfaces (e.g., rub-
ber foam) during operation. This may reduce or block the
electronics’ air supply. Do not cover the pumping unit.
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.
