INSTALL ATION and OPERATION MANUAL
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.
The water heater can be used for producing of domestic hot water (DHW) only in the manner described in this
manual.
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.
1. 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 boiler to the installation, check all screw connections (bolt inspection cover
flange, plug and anode). In very rare cases - during transportation, loading and unloading operations -
the screw connections may be loosen.
•The tightening torque for flanges is around 35 Nm.
•Before commissioning, check the installation for leaks
•Do not exceed the working pressure of 10 bar.
•If there is a risk of freezing of water in the tank - drain the tank completely or let the water heater
works continuously.

2. Description of water tank
The water heaters BB Q/S1 EXT series are used for producing of domestic hot water (DHW).
BB Q/S1 EXT models have compact and efficient water heater with one heat exchanger coil.
Designed for connection to a diesel boiler of gas boiler. Diesel boiler (or gas boiler) can be placed on top of
the water heater. This is a space-saving solution for smallinstallation room.
The load capacity of the boiler is up to 280 kg. in the area of the load surface.
The boiler shall be placed on a minimum of 4 contact / support points on the load surface: at a straight line
length of 150 to 200 mm from the center line at a width of 100 mm from the outer edge.
Product features:
• High efficiency insulation and outer casing of PVC
• Complex corrosion protection realized by means of titanium enamel and anode protection
• All threads are external.
• The large heat exchange surface of the coil allows fast and efficient heat transfer
• Easy installation
2.1. High efficiency 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 water heaters BB Q/S1 EXT series have a high efficiency insulation (DIN 4753, part 8) and outer casing of
PVC with RAL.
2.2. Water tank
Water tank is made of low-carbon steel S235JR, tightly covered with titanium
enamel on the inside. It is then baked to produce a smooth and uniform deposition
- free glazing. Thus the domestic hot water remains clean, and the water tank is
protected against corrosion.
All threads are external (see technical parameters).
