pump is connected to AC power. Unplug the pump be-
fore setting the voltage selection switch. Note: If the
pump is switched on with wrong voltage selection, the
motor may be damaged!
• 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.
Keep a minimum distance of 8 in (20 cm) between the
cooling fan and surrounding items (e.g., housing, walls,
etc.). Check fan regularly for dust/dirt. Clean fan guard
grill if necessary to avoid a reduction 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.
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.
