2. Installation

Installation should be done by a specialist with suitable qualifications (connecting the heater should be noted down in the warranty card). Due to the design

of the water heater, it can be installed only VERTICALLY.

The water heater must be connected directly to the water supply network (with the possibility of disconnection in case of maintenance) with a pressure not

exceeding 1 MPa - approx. 10 bar, and the minimum pressure can not be lower than 0,1 MPa - approx. 1 bar. If water pressure in the water supply network

exceeds 1 MPa - approx. 10 bar, it is necessary to reduce the pressure by using a reduction valve.

A safety valve, for example ZB8 FACH Cieszyn, must be installed on the cold water supply pipe, while the safety valve, equipped with a function that reduces

water pressure in the water heater through redirecting its flow back to the water supply installation, with a water supply installation that, for a distance of

5 m from the safety valve, should withstand a water temperature of 90°C (due to the possibility of hot water flow from the tank to the installation).

The outlet of the safety valve must be open all the time – connected with a normal atmosphere.

The tank acts as a buffer loaded from the top with warm water, which does not mix with the cold water occupying the bottom section of the tank. This

solution greatly enhances the comfort of using a dual function boiler, resulting in a large amount of heated water in a short time. A 3-stage circulation

pump (standard) of adjustable output allows the tank to work with dual function boilers of various outputs, without the risk that they will switch off due

to overheating of the water flowing into the tank. Its compact size makes it possible to locate the tank right beneath your boiler, and this means easy and

quick installation even in small spaces.

The outer body of the circulation pump is made of composite. The maximum force

that can be used to screw the pump can not exceed 30 Nm.
