Installation and operating instructions Wilo-CronoLine-IL/CronoBloc-BL (with cartridge mechanical seal)
• For a vibration-insulated installation, a simultaneous isolation of the
base block itself from the building structure by an elastic intermediate
layer (e.g. cork or Mafund pad) is required for few pump types.
CAUTION! Risk of property damage!
Danger of damage due to incorrect handling.
• A missing base or an incorrect installation of the unit on the base
can lead to a malfunction of the pump; this is excluded from the
guarantee.
A hook or eyelet with the corresponding bearing capacity is to be
installed vertically above the pump (for the total weight of the pump:
see catalogue/data sheet), to which hoisting gear or similar aids can
be attached when conducting maintenance or repair work on the
pump.
CAUTION! Risk of property damage!
Risk of damage due to incorrect handling.
• Only use lifting eyes on the motor for carrying the weight of the
motor and not for carrying the entire pump.
• Lift the pump using permitted lifting gear (see chapter 3 "Trans-
port and interim storage" on page 33.)
NOTE:
Shut-off devices shall be installed in front of and behind the pump in
all cases, in order to avoid having to drain the entire system when
checking, servicing or replacing the pump. If need be, the necessary
non-return valves are to be provided.
• The lantern has an opening on the underside which allows a drainage
pipe for condensation water/condensate to be connected (e.g. when
used in air-conditioning or cooling systems). The condensate gener-
ated can then be effectively drained.
• The pipes and pump must be free of mechanical stress when installed.
The pipes must be fixed in such a way that the pump is not supporting
the weight of the pipes.
• The air vent valve (Fig. 29 /30/31, item 1.31) must always face
upwards.
• Installation position: Only vertical installation is permitted (see
Fig. 40).
• BL series monobloc pumps are to be mounted on a sufficiently strong
base or mounting brackets (Fig. 41). For pumps of BL type, the motor
must be supported from a motor power of 18.5 kW, see installation
examples BL (Fig. 42).
Only pump type design B: For motor power from 37 kW four pole or
45 kW two pole, the pump housing and motor must be supported.
Suitable supports from the Wilo accessories range can be used for this
purpose.
NOTE:
The motor terminal box must not face downward. If necessary, the
motor or motor impeller unit can be rotated once the screws have
been loosened. While rotating the motor or motor impeller unit,
ensure that the housing O-ring seal does not become damaged.
