If there are any existing connections, ensure that they are not blocked. The pipes should be
kept as short as possible. The piping of the supply line in PVC must be executed in the
dimension d25-3/4”. Increase the nominal width for lines longer than 20m or in case of poor
pressure conditions.
Ensure that the connection sleeves for the water withdrawal and the dosing point are
completely open (metal sleeves may be rusted shut)
Line connection design
Line connections should always be installed laterally.
Figure 18, Line connections
Connect the Inlet ball valve
(Pos 4, Figure 5)
of the GRANUDOS 45/100 to the water
withdrawal point. The separation of dissolving and measuring water occurs in the dosing
device.
There are 3 possibilities for the water withdrawal point:
Possibility 1
, Swimming pool water directly from the pool
(
CPR Touch XL
only)
Water withdrawal at least 80cm below the upper edge of the water. The flow pressure at the
GRANUDOS Inlet must be at least 0.2barg. Install the GRANUDOS 45/100 a short distance
below the level of the withdrawal point. The height difference between the GRANUDOS and the
water surface should be at least 2m.
Avoid a rising and falling of the Inlet line in the piping to the GRANUDOS 45/100. This can lead
to the formation of air cushions that may subsequently enter the pump during operation.
Possibility 2
,
Swimming pool water before the swimming pool filter
(for
CPR Touch XL + Touch
and S5
)
Only use this alternative only in exceptional cases when Possibility 1 cannot be realised!
Water withdrawal between circulating pump and filter, prior to chemical dosing with 3/4 " sleeve.
The flow pressure at the Granudos Inlet must be at least 0.2barg. It may be necessary to add the
measuring water separately if the distortion is too strong on the way through the splash water
basin. Check the water quality!
Possibility 3
, Swimming pool water upstream of the swimming pool filter
(for
Touch + S5
)
Water withdrawal between filter and heat exchanger, before chemical dosing with 3/4" sleeve.
The flow pressure at the GRANUDOS inlet must be at least 0.2barg.
