INSTALLATION and OPERATION MANUAL
Version 0.6

Dear 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 manufacturer and is not responsible for the occurrence of defects or failures.

INSTRUCTIONS TO INSTALLER

**** The preparation, installation and commissioning must be performed by an authorized 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 SUNSYSTEM parts.
1.1. Requirements to Water Tank installation room**
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 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. DESCRIPTION ON HYGIENIC COMBI TANK
Hygienic Combi tanks are used to produce and accumulate sanitary hot water and hot water for space-heating system.
Coil-in-Tank construction – Flexible stainlesssteel 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.
HYG-B series – Inlet/Outlet arrangement – 90 angle degrees.
HYG-B models, the heat source is an electric heater.
HYG-BR models have a built-in heat exchanger (coil type) designed to connect to a solar installation or boiler. Option for installation of an electric heating element.
HYG-BR2 models have two built-in heat exchanger (coil type) for connection to the solar system and boiler. Option for installation of an electric heating element. sonal
2.1. Removable insulation and outer casing.
The quality of the insulation of a water heater is a key factor for its heat conservation capability and energy efficiency.
All Hygienic Combi tanks HYG series/ HYG-B series have Removable insulation with thickness 100 mm (DIN 4753, part 8) and outer casing of PVC with RAL 9006 color.
2.2. Water tank.
Floor standing. Water tank is made of low-carbon steel S235JR, DHW tube of sanitary grade stainless steel -316L, heats up instantaneously.
All threads are internal (see technical parameters).
2.3. Electric heating element.
Outlet connection of electric heating element 1 ½“ : 3000W/230V;4500W/230V; 6000W/230V; 7500W/400V.
**** The connection of the electric heating element to the electric power supply must be done by a qualified electricians.
When connect the heating element to the electric network, make sure that it is properly grounded.

Wiring diagrams 2.4. Thermostat
The thermostat may be adjusted by the user within the range 30°С ÷ 80°С, and the thermal protection would go off in case the water reaches 95°С.
This is an adjustable double THERMOSTAT which is designed to regulate the water temperature and ensures safety tolerance; it can be manually adjusted (TLSC model) or automatically adjusted (TLSC/A model).

CONNECTING OF RELIEF VALVE

TO WATER TANK
3.1. Connecting of Buffer tank.

3.2. Connecting of Stainless HYG coil.

**** Stop (Shut-off) valves should never  be installed between a safety (relief)valve and the tank. It is recommended once a year to check the operation of the safety valve.

TRANSPORT AND PACKAGING

We recommend to transport the water tank to the installation site in its packaging placed on the pallet, and stretch foil.
During transport and installation, depending on the weight, appropriate safety equipment must be used in accordance with Directive 2006/42/EC.
When transporting items weighing more than 30 kg, the use of pallet jack, fork truck or other hoisting devices is a must.
Hygienic Combi Tanks can be with or without insulation. They are secured on a pallet packed with foil.
Insulation, decorative cover and rosettes can be delivered separately.
Advantages:

• Easy transportation (takes less space at transportation).
• Easy conveyance to the place of installation.
• Easy and quick packing of water heaters with soft insulation. All necessary openings in the casing are made beforehand, and the installer has only to find them and take them out.

The casing is fastened by a zipper at the assembly platform.
