Water Installation
1. Ensure adequate cold water supply pipe size is installed to maintain
the pressure and flow when multiple units are installed(100-1000 kPa)
2. Allow for a full bore stop cock without any flow restriction to be fitted
in the cold water supply to each Hotrun
3. Connect the Hotrun only with the flat seal flexible hoses supplied.
(too much torque on the fittings can damage the internal copper coil)
4. Fit the supplied flow restrictor to the cold water inlet on the Hotrun.
