ES3, ES4 & ES6 Instructions. Issue: No. 2 Page 2 February / 2012

Description

Zip InLine ES3, ES4 and ES6 instantaneous water heaters are compact

electronically controlled instantaneous water heaters for hand washing.

This small instantaneous water heater 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.

The heater is pre-set in the factory to an outlet temperature of about 38°C, which is

ideal for hand washing. When this temperature is reached, the electronic regulator

reduces the power in order to ensure that the outlet temperature does not exceed

this value. This automatic temperature regulation means that it is only necessary to

open the hot water tap to obtain water at a constant, safe temperature for washing

hands. If the set outlet temperature is not reached, slightly reduce the ﬂow of water

from the tap. Cold water may be added if a lower temperature is required.

If the ﬂow rate is too low or if the hot water tap is closed, the appliance switches

itself off automatically. For an optimum ﬂow of water, always ﬁt the special jet

regulator supplied with the appliance. This regulator should be inserted into the

threaded retainer on the tap outlet.

The maximum possible outlet temperature is determined by the temperature

of the incoming water, the ﬂow rate and the heating power of the heater.

The temperature set point and ﬂow rate can be preset inside the appliance to

achieve an outlet temperature between about 30°C and 50°C.

Power consumption is also regulated based on outlet temperature to ensure

the required temperature is achieved exactly to the degree and irrespective of

ﬂuctuations in voltage and water pressure.

The maximum inlet temperature of 60°C is suitable for use with preheated water

e.g. from solar heating systems.

Approvals

Zip InLine ES3, ES4 and ES6 are VDE approved to the LVD and EMC directives

and CE endorsed.

Zip InLine ES3, ES4 and ES6 have been examined, tested and found when correctly

ﬁtted to comply with the requirements of the United Kingdom Water Regulations /

Byelaws (Scotland). The products are listed under the WRAS (Water Regulations

Advisory Scheme) Water Fittings and Materials Directory.

CAUTION

• Optimum operation is ensured at a water ﬂow pressure of 0.2 to 0.4 MPa

(2-4 bar). The appliance must not be subjected to pressure exceeding

1.0 MPa (10 bar).

• The appliance must only be used when correctly installed and in perfect

working order.

• The appliance must be installed in a frost-free room and must never be exposed

to frost.

• The ES range is not recommended for use with thermostatic mixing valves or

taps.

• The appliance must be completely ﬁlled with water before being switched on.

• Before commissioning for the ﬁrst time and each time the appliance is emptied

(e.g. due to work on the plumbing system or maintenance), the appliance

must be vented by opening and closing the hot water tap until all air has been

eliminated from the water heater and no more air emerges before re-connecting

to the electrical supply.

• The appliance must only be used for heating potable water. The speciﬁc water

resistance must not fall below the required value indicated on the rating plate.

The appliance must not be used for any other purpose.

• Incoming water temperature must not exceed 60°C.

• When the appliance has been in use for some time, the ﬁttings may be very

hot.

• If inlet temperature is up to 60°C (eg. fed from a solar supply) mixing with cold

water will be required to ensure a safe temperature at the outlet.
