• The installation and maintenance must be carried out by a professional from the sector in accordance with manufacturer’s instructions. (p. V 1-2- 3-4).

• The buffer must only be installed in premises with normal fire resistance. There should be a siphon connected to a plumbing drainage.
  The premises should be protected from freezing and the temperature should never be lower than 4 °C

• Qualified P&P specialists and Electricians must only perform the connecting of the buffer to the local or central water heating, solar panel and electric mains.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

• Children should be supervised to ensure that they do not play with the appliance.

• If the probability exists for the premise’s temperature to fall below 0°C, the water heater must be drained via raising the safety return-valve’s lever.

• The safety valve must be left open to the atmosphere.

• When connecting copper pipes to the inlets and outlets, use an intermediate dielectric connection. Otherwise there is a risk of contact corrosion that can occurs on the connection fittings!

• For the connection of copper pipes to the inputs and outputs, use an intermediate dielectric connection. Otherwise there is a risk of occurrence of contact corrosion connecting fittings!

• In order to secure the water heater’s safe operation, the safety valve must undergo regular cleaning and inspections for normal functioning / the valve must not be obstructed/.

• This Device and its heat exchangers are intended for use with water and mixture of water and Propylene (Ethylene) GLYCOL at liquid state. The presence of anticorrosion additives is obligatory. Using different fluids in different states leads to warranty violation!

IMPORTANT! Usage of this device at temperature and pressure level above prescribed leads to warranty violation!

INTENDED USE

The appliance is designed to accumulate excess heat currently produced by the boiler and releasing it for use at peak demand. It is designed for use in closed and heated rooms (above 4°C) in a closed heating systems with maximum pressure up to 0,3 MPa (3 bar). Heat carrier must be circulating water or a mixture thereof with propylene glycol and anticorrosion additives!

DESCRIPTION OF THE APPLIANCE

Depending on the model of the high capacity water heater (HCWH), it can has one or two built-in heat exchangers. The connections to the high capacity buffers should be made following the market outlets and inlets, described below: TS1, TS2, TS3, ТSS1,TSS2 – for mounting temperature sensors (each heat exchanger can be controlled by temperature). If the appliance is equipped with one heat exchanger there will be only one outlet “TS1” available.( fig.1,1a,1b,1c,1d,2a,2b)

MOUNTING AND CONNECTION

ATTENTION! Qualified technicians must perform all technical and electrical assembly works.

INSTALLATION

Buffers are delivered on an individual transport pallet. If the high capacity buffers are used in premises with low humidity and flat floor you can leave the pallet as it is mount on the appliance, otherwise – please follow the described steps bellow (fig. 4):

• Put the water heater in horizontal position;
• Unscrew the three bolts which hold the pallet to the бuffer;
• Mount the adjustable feet directly to the appliance;*
• Put the high capacity water heater (HCWH) in vertical position and adjust the level using the feet.
  *If the adjustment feet are delivered in separate parts you can assemble them as follow (fig. 5):
• put the part 1 on bolt 2 which is unscrewed from the pallet
• put the washer 3 which is removed from the pallet
• Screw on the nuts 4 which are delivered with the appliances

ATTENTION! In order to prevent injury to user and/or third persons in the event of faults in the system for providing hot water, the appliance must be mounted in premises outfitted with floor hydro insulation (or) plumbing drainage.

MOUNTING OF INSULATION 800-2000 Ltr.

For the installation of insulating material two persons, in the case of very big boiler, three persons are needed. The temperature of the room where the fitting takes place should be at least 18°C. The insulation set should be stored at above mentioned temperature at least one hour before operating!
In the next step both sides of the zipper have to be pulled with light traction into the direction of the arrows shown in FIG.6. Please take care that the prefabricated holes stay in place and the connections are accessible all the time.
It is important to make sure that both sides of the zipper do not remain more than 20mm apart from each other after being fitted (Fig.6). Now push both sides of the zipper to the boiler and fix them on the first position. If necessary, the insulation can be narrowed (Fig.6) down again.
Once the insulation material has been fitted correctly and fastened with the zipper,
the foamed material is inlayed and closed with a plastic lid on the top. Finally, rosettes can be fixed onto the connections (Fig.6).

The insulating set should only be stored in a dry place! We cannot be held responsible for damage because of failure to observe these instructions!

CONNECTING THE SERPENTINES (HEAT EXCHANGERS) WITH HEATING INSTALLATION USING ALTERNATIVE AND RENEWABLE SOURCES

ATTENTION! Qualified P&P specialist and technicians must perform all assembly works for connection to the heat sources.

The connection of the serpentines (heat exchangers) with the heating installation should be done considering the marked outlets and inlets as described below:
IS1 (MS) – Inlet of heat exchanger 1;
OS1 (ES) – Outlet of heat exchanger 1;
IS2 (M) – Inlet of heat exchanger 2;
OS2 (E) – Outlet of heat exchanger 2.
Make sure that the system is empty of air. The presence of air may cost incorrect work of the boiler. Maximum temperature of the heat transfer fluid: 110°C. Maximum pressure of the heat transfer fluid: 0.6MPa!A safety valve inline coil heat exchanger have to be fit according to HVAC designer requirements but its adjustment must not be higher than Pnr = 0.6MPa. (EN 1489:2000) An expansion vessel according to HVAC Designer requirements must be installed!

CONNECTING BUFFERS TO THE CENTRAL HEATING LOOP. EXAMPLES.

Buffers for central heating system are intended for heat accumulation and stratification with subsequent distribution of heat flows with different temperatures to the specific consumers. As an example, on Fig.7 is shown high and low temperature heating realized by buffer. Heat demand is covered by gas boiler and solar collectors.

1. Buffer
2. Boiler
3. High temperature heating
4. Low temperature heating

ATTENTION! The buffer is a part of a complete heating system that must be designed and checked by specialized and authorized personnel! The installation of a safety valve with the exact release rate is obligatory!!! The maximum designed pressure of the buffer is 3 Bars! Expansion vessel, calculated by the designer, is a compulsory element of the installation!

OPERATING MODE

Before using the buffer make sure that the appliance is connected with the heating installation in correct way and is filled with water.

PERIODIC MAINTENANCE

The manufacturer recommends preventive maintenance of your water heater every two years by an authorized service center or service base.
(fig.30) Each preventive maintenance of the said type must be entered in the appliance’s warranty card and must outline date of performing the preventive maintenance, company performing the preventive maintenance, name of person performing the preventive maintenance, and signature.

Failure to comply with this requirement may terminate free warranty maintenance of your buffer.
The manufacturer does not bare the responsibility for all consequences.

INSTRUCTIONS FOR ENVIRONMENTAL PROTECTION

Old appliances contain valuable materials and because of this should not be disposed with other products. To protect the environment we kindly ask you to surrender them in approved centers only!o surrender them in approved centers only!
