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).
7. Installation Installation site • Appliance must only be installed in frost-free rooms. Never expose appliance to frost. • The Appliance is designed for wall mounted installation and has to be installed with water connectors upwards. • The appliance complies with protection class IP 25. • In order to avoid thermal losses, the distance between the instantaneous water heater and the tapping point should be as small as possible (< 0.5m).
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.
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.
8. Commissioning Commissioning 1. Close the circuit breaker to connect the electrical supply. 2. Check everything is working as it should and the water temperature is achieving the desired temperature. If not follow the guide below to correct the temperature. 9. Flow rate adjustment Adjustment of the flow rate is to be done by a Qualified Technician. Adjustments are done by turning the adjusting screw located under the appliance’s cover.
9. Flow rate adjustment Adjustment of the flow rate is to be done by a Qualified Technician. Decreasing the flow rate: Turning the adjusting screw clockwise decreases the flow rate, thus making a higher outlet temperature possible. Increasing the flow rate: Turning the adjusting screw counter-clockwise increases the flow rate, thus reducing the possible outlet temperature. Direction Flow Temperature increase (+) / decrease (-) – + + – 10.
11. Maintenance • The appliance and fittings should only be cleaned with a damp cloth. Do not use abrasive or chlorine-based cleaning agents or solvents. • Keep the control panel area dry. • Clean the jet regulator regularly and replace as necessary. • Dirt and scale deposited in the pipes and appliance will affect its function. Typical indications of this are a reduced flow rate or noisy flow.
