How to select the correct Grander unit for a specific application
Normally, a Grander unit will be selected to match the internal diameter of the water pipe. However, in certain circumstances, a larger unit may be appropriate based upon several parameters including;
* Peak flow rate
* Intensity of water use
We recommend on-site consultation by a Grander consultant to ensure the correct choice of unit, ensuring optimum
performance. Installation
Units from ½” to 2 ½” are supplied with European Standard brass nipples. For the UK market, special adaptors are provided to allow direct connection to metric copper pipe. (eg. 15 mm, 22 mm etc.)
The 3” and 4” units are supplied with flanges DN80 and DN100 respectively (in accordance with DIN 2633).
Mounting: Due to their weight, the flanged units MUST be mounted on a secure base to avoid excessive strain on the connection.
The smaller units may require additional pipe support brackets either side of the unit.
Please note:
Normally, a unit corresponding to the pipe dimension provides adequate performance. However, in certain intensive applications or demanding water conditions, it may be recommended to use a larger unit. Guarantees:
- 3 months money-back guarantee
- 5 years warranty on the unit and its function
