1. Instructions to the InstallerDear Customers, We strongly hope that the appliance you have bought from us will contribute to creating comfort at you homes and decreasing the energy expenditure.

This manual contains important information for the safe and correct installation, start-up and trouble-free operation and maintenance of the water heater.

Hygienic Combi Tanks can be used only in the manner described in this manual – to produce and accumulate sanitary hot water and hot water for space-heating system.

The application and any other was the area of operation is not recommended by the manufac-turer and is not responsible for the occurrence of defects or failures.

Note: The preperation, installation and commissioning must be performed by an authorizedprofessional installer / service.

During installation and operation, the country specific requirements and regulations must be observed:

• local construction regulations on installation of water tank; weight of the boiler to comply with the stability of the floor of the room where it will be installed. • regulations and norms concerning the fitting of theinstallation with safety devices. • safety during installation - personal protective equipment

Use only original parts

When choosing a room for tank installation observe the following requirements:

• to have a drainage channel. Some maintenance procedures require draining of all water from the tank. • Thermal insulation of the room. This provides efficiency of the appliance and prevents the water from freezing.

1.2 requIreMents for tank InstallatIon • The length of connecting pipes between the water tank and consumer must be as short as possible. • Before connecting the water tank to the installation, check all screw connections (plug and etc.). In very rare cases - during transportation, loading and unloading operations - the screw connections may be loosen. • Before commissioning, check the installation for leaks • Do not exceed the working pressure of 3 bar for buffer tank and 6 bar for hygienic stainless steel coil. • If there is a risk of freezing of water in the tank - drain the tank completely or let the water tank works continuously.


2. DescriptionHygienic Combi tanks are used To produce and accumulate sanitary hot water and hot water for space heating system.

Coil-in-Tank construction- Flexible stainless-steel coil for sanitary hot water + Buffer tank powering space heating system. Sanitary water heats up instantaneously as it flows through the large surface stainless coil. Thus water is delivered hot while still fresh and clean of depositions.

2 Heat Exchanger Models: these models have a heat exchanger for your potable water and a second heat exchanger for your solar energy system connection.

3 Heat Exchanger Models: these models have a heat exchanger for your potable water, a second heat exchanger for your solar energy system con-nection and a third heat exchanger for connecting your boiler as a backup heating source.

2.1 Removable INSUlaTIoN & oUTeR CaSINg The quality of the insulation of a water heater is a key factor for its heat conservation capability and energy efficiency.

All CTEC tanks have a removable insulation with a thickness of 4 inches (DIN 4753, part 8) and an outer casing of PVC with RAL 9006 color.

2.2 the tank Floor standing. Water tank is made of low-carbon steel S235JR.
