Scope Of Supply; Accessories; Electrical Wiring - Wilo VeroLine-IPL Serie Notice De Montage Et Mise En Service

English
When used in conjunction with an automatic
variable speed controller only the base-duty
pump is operated variably. The second pump
remains available for parallel operation to cover
peak-load demand and additionally, for standby
duty to take over under fault conditions.

4.2 Scope of supply

IPL:
• Single pump
• Installation and operating instructions.
DPL:
• Double pump
• Installation and operating instructions.

4.3 Accessories

Accessories must be ordered separately.
• PTC trip relay for switchboard mounting.
• IPL and DPL: 3 support feet and sundries for base
mounting.
• DPL: Blind flange for repair purpose

5 Siting / Installation
5.1 Installation
• Installation only after all welding/soldering on the
pipework is completed and the pipe system has
been flushed out. Foreign matter and impurities
may cause damage to the pump.
• Standard design pumps must be installed in a
frost- and dustfree, well-ventilated and non
potential explosive environment.
• Mount the pump in an easily accessible position in
order to facilitate later inspections or exchange.
• Provide and place a hook or eyebolt of respective
load bearing capacity (total weight of pump: see
catalogue/data sheet) vertically above the pump,

suitable for taking lifting gear or other mechanical
aids capable of handling the pump for mainte-
nance or repairs.
• The pump must be carefully handled by means of
authorized lifting gear (see chap. 3).
• Minimum axial clearance between a wall and the
motor fan cover: clearance required for removal to
min. 200 mm + Ø of fan cover.
• Isolating valves must be provided and installed on
suction and discharge ports in order to avoid drai-
ning the whole pipe system when servicing or
exchanging the pump.
• At the risk of backflow a non-return valve must be
provided.
• Pump must be mounted free of stress from the
pipework. The pipes must be attached in such way
that the pump does not bear the weight of the
pipes.
• The venting valve always must face upwards (Fig.
4, 5, pos. 2.1).
• When pumps are used in airconditioning/cooling
systems, it is possible to drain off the condensa-
tion of the lantern through drilled holes.
• Any mounting position except „motor down-
wards" is allowed.
The mounting position with horizontal motor
shaft of the IPL and DPL range is permissible for
pumps with 7,5 kW motor power.
Mounting positions: IPL see Fig. 1
DPL see Fig. 2
The motor terminal box must not face downwards.
If necessary, the motor or the motor impeller unit
can be turned after removing the screws.
When turning, take care not to damage
ATTENTION!
the housing o-ring.
When sucking from tank make sure that
ATTENTION!
the level of liquid is always above the
pump suction port to avoid dry-running of
the pump.The minimum inlet pressure
must be maintained.
For units which are be insulated, only the
ATTENTION!
pump housing may be insulated, not the
lantern and the motor.

5.2 Electrical wiring

All electrical wiring to be carried out by qualified
and licensed electricians in strict conformity to
ruling local regulations.
• All wiring and external gear must comply with
ruling regulations (use of cables, all-pole swit-
ches, air gaps, etc. in accordance with the latest
edition of IEE wiring regulations).
• For protection against drip water and to ensure a
firm gland grip the mains supply cable must be of
sufficiently large size. The position of the
cableentrance in electrical connection box of the
motor or the cableposition has to protect the
electrical connection box against drip water.
