installation. Failure to comply with the safety pre-
cautions invalidates any claim for damages.
In particular, failure to comply may lead to problems
such as:
– Failure of important pump or installation func-
tions,
– Injury resulting from electrical or mechanical fac-
tors.

Safety precautions for the operator

The existing national regulations for the prevention
of accidents must be followed.
All risks caused by electrical energy must be elimi-
nated. All directives issued by the VDE [German
Association of Electrical Engineers] and the local
electricity supply companies must be observed.
2.5 Safety information for inspection and
assembly
All existing national regulations for the prevention
of accidents, as well as all available internal work,
operation and safety instructions issued by the
operator, must be followed.
The operator must ensure that all inspection and in-
stallation work is carried out by authorized and
qualified specialists who have carefully studied
these instructions.
Work on a pump or installation should only be car-
ried out once the latter have been brought to a
standstill.
All of the applicable safety and protection installa-
tions must be reattached and switched back on im-
mediately following completion of work.
2.6 Unauthorised modification and
manufacture of spare parts
Alterations to the pump or installation may only be
carried out with the manufacturer's consent. The
use of original spare parts and accessories autho-
rised by the manufacturer will ensure safety. The
use of any other parts may invalidate claims invo-
king the liability of the manufacturer.
2.7 Unauthorised operating methods
The operating safety of the pump or installation
supplied can only be guaranteed if it is used in ac-
cordance with paragraph 1 of the operating in-
structions. All values must neither exceed nor fall
below the limit values given in the catalogue or data
sheet.

Pump description

The pump has a wet-running motor (single-phase
current (1~) or three-phase current (3~)), for mains
connection voltage and mains frequency see ra-
ting plate, (Chap. 1.2.2), in which all rotating parts
are surrounded by the pump medium. Depending
on the design of the pump, the pump medium may
lubricate the friction bearing rotor shaft.
The motor speed can be adjusted by different set-
tings (not for TOP-D). Depending on the terminal
box provided, switch to the required speed manu-
ally either by turning the switch knob or moving the
switch connector to the relevant socket (Chap. 6.2).
A switching connector is available as an accessory
for voltage range 3 ~ 230 - 240 V.
The section entitled "Terminal boxes" indicates
which terminal boxes are attrib-uted to each indi-
vidual pump type.
TOP-SD:
Double pumps contain two identically constructed
pump heads in a common pump housing.
TOP-Z:
The pumps in this range are specially designed to
cope with the operating conditions present in drin-
king water circuits. According to the German drin-
king water regulation 2001, pump housings in
bronze (CC 491K) have to be used in systems.
TOP-D:
The maximum speed is 1400
1
/min, speed constant.
