Safety

• Read this manual carefully before installing the pump and putting it into operation.
Non-observance of these instructions may cause serious damage to the pump that is
not covered by our guarantee terms. Follow the instructions step by step.
• Depending on the design the pumps are suitable for liquids with a temperature of up
to 140°C. When installing the pump unit to work at 65°C and above the user should
ensure that appropriate protection measures and warnings are fitted to prevent
contact with the hot pump parts.

General

• The area in which the pump unit is to be placed should be adequately ventilated. A too
high ambient temperature and air humidity, as well as a dusty environment may have a
negative effect on the functioning of the electric motor.
• The foundation for a CBH pump must be hard, level and flat.
• The cooling air inlet of the motor should be positioned in such a way that unobstructed
air supply is ensured.
• Make sure that the system pressure is always below the maximum allowable
operational pressure. For exact values see paragraph 10.1 "Technical data pumps".
• If the pumped liquid is harmful to men or the environment, take appropriate measures
to drain the pump safely. Possible leakage liquid from the mechanical seal should also
be discharged safely.

Accessories

• In case the pump is provided with an isolation, special attention has to be paid To
temperature limits of shaft seal and bearing.

Piping

As regards the piping and connecting points of the pump attention should be paid to the
following:
• The piping to the suction and delivery connections must fit exactly and must not be
subject to stress during operation. For the maximum allowable forces and moments on
the pump flanges of a CBH pump see paragraph 10.8 "Permitted forces and torques
on the flanges for CombiBlocHorti".
• Preferably a CL pump should be mounted in the piping in such a way that the direction
of flow is vertical, so as to prevent air from remaining in the pump. Air in the pump may
cause damage to the mechanical seal!
• Make sure that the system has one or more draining apertures. Also, it should be
possible to bleed or de-aerate the system, preferably directly above the pump.
