Product Data; Technical Data; Scope Of Delivery - Wilo CO-HELIX-V 4 Instrucciones De Instalación Y Funcionamiento

The pipes will not withstand loads and should
not be used to secure loads in transit. Some sti-
ckers on manifolds reminds this advice (Fig. 2b).
ATTENTION! Loading the pipes in transit can result
in leaks.
• When the product is delivered, check it for any
damage in transit. If any defect is found, inform the
delivery company (forwarding agent).
The pumps transport lock (if equipped) should be
removed before the start o the pump (sticker Fig. 2c,
2d).
ATTENTION! If the product is installed later on,
store it in a dry place. Protect it from impacts and
any outside influences (moisture, frost, etc. ...).
Handle the product with care.
4. Application
The booster is designed for boosting and maintaining
the pressure when the water supply network is not
well dimensioned or does not exist.
When a speed converter is integrated in the pumps,
the electronic regulation system integrated in the
control unit allows to get a constant pressure in the
water supply network whatever the flow is.
The booster is either or supplied:
- On load: from the public water mains or from a
mains collection tank.
- On suction: (on demand).
