6. Description of applicance
The Zip instantaneous water heaters are compact electronically controlled water heaters. It is intended to provide economical heating of
water for a wash basin when installed together with a sanitary water fitting. When the hot-water tap is opened, the heater switches itself
on automatically when the minimum water flow rate is exceeded and heats the water as it passes through the appliance.
There are 3 available temperature settings, 35ºC, 38ºC and 45ºC (Max).
For best performance, always fit the special flow controller included with the appliance. This controller is inserted into the outler at the
end of the tap and fits into any standard sleeve size M 22/24.
The maximum possible outlet temperature is determined by the temperature of the incoming water, the rate of flow and the heating
power of the appliance.
This appliance delivers water not exceeding 50ºC in accordance with AS3498.
7. Installation
The following regulations must be observed:
• Installation must comply with all statutory regulations, AS/NZS 3000, AS/NZS 3500, as well as those of the local electricity and water
supply companies.
• The specifications on the rating plate. The rating plate is located under the appliance‘s cover. See Section 10 on removing the cover.
• Technical specifications.
• These instructions must be read and fully understood before commencing the installation. If in doubt, or in need of further guidance
please ring Zip on 1800 638 633.
• Zip Instantaneous Hot Water heaters must be installed by a competent person familiar with electric instantaneous water heaters.
• Zip Instantaneous Hot Water heaters must be installed according to the specifi cation on the rating plate and the technical specifi cations.
• The appliance must be permanently connected to the electrical supply through an isolation switch as per AS/NZS 3000.
• To protect the appliance, a circuit breaker must be fi tted with a rating suitable for the nominal current of the appliance.
• The cross sectional area of the connection cable must be in accordance with the power rating of the appliance and the specifi c
requirements of AS/NZS 3000.
• Take care to protect the wiring from damage during installation and ensure that the wiring is not directly accessible after installation.
• Check that the power supply is switched off prior to electrical connection.
• This appliance must be earthed.

7. Installation
Pipe connection
1. The cold water inlet (blue) and hot water outlet (red) are marked on the rating plate. Connect the appropriate pipes from the tap to the
water inlet and outlet accordingly. Avoid exerting any mechanical pressure on the appliance by applying a spanner on the flats of the
inlet and outlet connections when tightening the pipe connectors (Fig.3).
2. Once the water connections have been made, check for any leaks and rectify as necessary.
3. In order to obtain an optimum water jet at low flow rates, always screw the jet regulator supplied with the unit onto the tap outlet.
This insert fits commercially available sleeves with an M22 or M24 thread.
4. To remove the water heater, insert a wide bladed screwdriver behind the unit from above and gently lever the unit out of the wall
bracket.

7. Installation
Electrical connection
Do not switch on the electric power at this time.
WARNING! To prevent damage to the appliance, the instantaneous water heater must be purged of air before using it for the first time.
Purging
Before connecting the electrical supply, open and close the hot water tap until the water runs smoothly and no more air emerges.
NOTE! Every time the appliance is drained (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the
heater must be purged in this way before reconnecting the power supply.
WARNING! This appliance must be earthed.
Installation must be carried out by a qualified electrician.
The electrical installation including earthing and cross bonding should comply with current Australian regulations and any Local Authority
requirements.
IMPORTANT:
The appliance must be installed according to the specification on the rating plate and the technical specifications. Ensure that the voltage
marked on the appliance matches the power supply.
The appliance must be permanently connected to the electrical supply.
To protect the appliance, a circuit breaker must be fitted with a rating suitable for the nomi nal current of the appliance.
The cross sectional area of the connection cable must be in accordance with the power rating of the appliance and the specific requirements of AS/NZS 3000.
Take care to protect the wiring from damage during installation and ensure that any uninsulated wiring is not directly accessible after
installation.
The cable must be adequately secured.
WARNING! Check that the power supply is switched off prior to electrical connection!
