Installation and operating instructions Wilo-CronoLine-IL, CronoTwin-DL, CronoBloc-BL
• 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 material damage!
Danger of damage due to unsuitable foundation/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 material 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 temporary storage" on page 33).
• Shut-off devices shall be installed in front of and behind the pump, in
order to avoid having to drain the entire system when checking, ser-
vicing 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.
• Installation position: All installation positions except for "motor fac-
ing down" are allowed.
• The air vent valve (Fig. 1/2/3/4/5/6, item 1.31) must always face
upwards.
NOTICE:
The installation position with horizontal motor shaft is permitted for
the IL and DL series only up to a motor power of 15 kW (Fig. 12). A
motor support is not necessary. Only the installation position with
vertical motor shaft is intended for a motor power > 15 kW. Only hori-
zontal installation is permissible for 2-pole BL pumps from 90 kW. BL
series monobloc pumps are to be mounted on a sufficiently strong
base or mounting brackets (Fig. 13).
DL
• For pumps of BL type, the motor must be supported from a motor
power of 18.5 kW, see installation examples BL (Fig. 14).
Only pump type design B: 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.
NOTICE:
The motor terminal box must not face downward. If necessary, the
motor or motor impeller unit can be rotated once the hexagon head
screws have been loosened. While rotating the motor or motor impel-
ler unit, ensure that the housing O-ring seal does not become dam-
aged.
