SAFETY

These instructions should be studied carefully before installing or operating the pump. They are meant to help
you with installation, use and maintenance and to increase your safety. Installation should only be performed
with regards to local standards and directives. Only qualified personnel should maintain and service these
products.
Failure in following these instructions can cause damage to the user or product and can void warranty. Safety
functions are only guaranteed if the pump is installed, used and maintained as described in this manual.

PUMP MEDIUM

Pump medium can be pure water or a mixture of pure water and glycol, which is appropriate for central heating
system. Water must meet water quality standard VDI 2035. The medium must be free from aggressive or
explosive additives, free from mixtures of mineral oils and solid or fibrous particles. The pump should not be used
for pumping flammable, explosive media and in an explosive atmosphere.
Permanent magnet rotor inside the pump is prone to accumulating magnetic particles on its surface, which can
lead to abrasion of bearings and rotor can or even blocking the rotor. Although the pump is built in a way that
the effect of magnetic particles is minimal, failures of bearings, rotor cans and blocked rotors are not a subject
of claims.
To improve pump resistance to magnetite we recommend the use of magnetite filter.
