safe and trouble free operation. If help and advice is required, please call 0345 6 005 005.
What is the Zip HydroTap®G4 ?
This Zip HydroTap®G4
is an electronically controlled, filtered and chilled water drinking system for the kitchen.
The HydroTap®G4 systems are under counter drinking water appliances with a dispensing tap mounted
on a sink or worktop, which has been designed for residential applications. The HydroTap®G4 utilises a
conventional refrigerant compressor to chill the water. This chilled model will dispense chilled water, factory
set to 6-10°C. These units are NOT designed to be used as sanitary fixtures.
The water filter is a disposable item which will require periodic replacement and is covered by a limited OEM
warranty.
It is important that the installation be undertaken safely, correctly and completely in order to utilise all the
benefits that the HydroTap®G4
can provide. Each tap can be ordered with the tap head assembly for disabled
use. The disabled levers are supplied with Braille caps for the visually impaired.

the sink bowl with ample clearance for a cup or tea pot. Alternatively,
the tap could be mounted away from the sink using a Zip Font, avail-
able as an accessory.
Apply a light smearing of silicon sealant
on the underside of the upper spacer to
ensure a watertight fi t.
