ACTIVITY DESCRIPTION
The Jäspi GTV Hybrid 500 energy heater is suitable alongside all forms of energy, both heat pumps and traditional heating modes. Product
design has been based on versatility, space friendliness and advanced energy economy.
Hybrid accumulators are energy accumulators developed alongside low-temperature systems (e.g. heat pumps and solar energy) that provide heating
of a waterborne floor and/or radiator system and hot water. Hybrid bookers are suitable for both new and renovation sites. The water space of the
500-liter Hybrid Accumulator is divided into two parts; a top of 300 liters and a lower part of 200 liters separated by an intermediate bulkhead with
a flow channel. At the bottom of the 200 litres, which serves as the buffer tank for the heating circuit, a solar charging spiral and a preheating spiral
of domestic water are located. The top 300 liters store energy for the needs of the domestic water cycle.
Jäspi Hybrid heaters are ideally
suited to all heat pumps on the
market, e.g. alongside rapidly
increasing air-to-water heat
pumps. If the consumption of
domestic water is consistently
particularly high,
or if the property has a po-
reamme, we recommend
connecting the Jäspi water heater
to the Hybrid Heater.
To ensure the yield of heating and
hot domestic water, the hybrid
heater heat pump combination is
always equipped with spare heat
sources, e.g. electricity. Jäspi
Elbox (6kW + 6 kW) is available
as an accessory for hybrid
accumulators
+ Power watch automation). Jäspi
Elbox's power guard car
automation enables efficient use
of the main fixed fuse by taking
into account the rest of the
property's electrical load.
1 Temperature distribution and combinations in hybrid use
Figure 1 shows the temperature distribution of the boiler water in hybrid use, where the upper part of the accumulator is heated hotter than the lower
part of the accumulator. The intermediate bulkhead below the halfway point of the boiler prevents the hot water at the top of the tank and the hot
water at the bottom of the tank from being mixed without need.

GtV Hybrid 500 bookers also have a solar spiral as standard. It is therefore easy to switch to the utilisation of solar heat later on. You can find
different models of the possibilities of utilising Jäspi Hybrid Accumulators at the internet address www.kaukora.fi.
Jäspi Hybrid Accumulators combines Kaukora Oy's over 30 years of experience in domestic water heaters and traditional energy accumulators.
Jäspi Hybrid accumulators are manufactured in Finland using the most modern production technology.
TRANSPORT AND HANDLING
It is recommended that the booker be transported upright. Do not leave the heater with moisture on sensitive flooring materials before installing it,
as condensation or test pressure water may leak from the container. Do not cover the paintwork with rubbers, plastics or fabrics, as the surface may
be damaged.

SOLAR SPIRAL
The boiler has one 6.3m long ø18mm solar charging spiral when installed at factory. The
liquid volume of the coil is 0.2 litres.
The heat transfer area outside the coil is 1.3 m².
GENERAL INSTALLATION INSTRUCTIONS
The accumulator is a model standing on the floor and requires a floor area of 665 mm x 675 mm. The charger is installed upright in a dry space near
the floor drain.
When planning the location of the accumulator, sufficient installation and maintenance space around the accumulator must also be taken into
account. When selecting the location, it should also be noted that the overflow pipe of the safety valve can be led to a nearby sewer, etc. It must also
be possible to empty the booker if necessary.
USE OF ELECTRICAL RESISTORS
Electrical connections of the accumulator may only be made by a qualified electrician. All electrical connections must comply with the current
specifications and instructions. N.B.! If foreign control voltages are connected to the boiler, accumulator or heat pump, the the device must be fitted
with the following warning text: "Note! The control voltage that is foreign to the appliance."
PIPE INSTALLATION
Pipe installations must be carried out in accordance with the current regulations. The structural pressure of the tank is 3 bar. The safety valve must be
connected to an overflow pipe and placed in an appropriate location, e.g. in the case of a safety valve. floor drain. On the possibility of emptying the
tank , e.g. care shall be taken care of through the group of safety devices.

USE
Before commissioning, it must be ensured that the piping has undergone a leakage test and that the accumulator is full of water. The tank must be
filled with water to avoid damage to any electrical resistors installed. The operation of the safety valve should be checked every 3-4 months, as its
lack of functioning may cause a hazardous situation. The valve is triggered by turning its knob counterclockwise, allowing water to flow through the
safety valve brick outlet. If this does not happen, the valve is defective and must be replaced.
MAINTENANCE
The operation of the safety valve should be checked every 3-4 months, as its malfunction may cause a hazardous situation. The valve is triggered by
turning its knob counterclockwise, allowing water to flow through the safety valve discharge pipe. If this does not happen, the valve is defective and
must be replaced.
The broken electrical part must be replaced with the original spare part. Maintenance must only be carried out by a qualified
electrician. Paint surfaces can be cleaned with diluted detergents.
To remove the domestic water spirals, remove the coil cover and cut a hole in the insulation behind the lid using a knife. After removing the
insulation, the thread can be removed by opening the bolts on the coil flange.
After removing the lower circulator, the solar coil can be removed through the operating water coil's installation opening, from the inner side. In
addition, the counter nuts of the solar spiral penetrations must be removed from under the surface damper to remove the coil.
TROUBLESHOOTING
• The boiler does not provide enough hot water.
The higher boiler temperature produces more domestic water, but especially in heat pump heating, the high temperature yield requirement for a heat
pump reduces the efficiency of the pump. See The operating description of possible actions.
• The safety valve drips water : NOTE! The drip of the safety valve is generally interpreted as having something wrong with it, even though it is
quite reversed. The safety valve will then work exactly as it should. The drip is caused by the thermal expansion of the water. In renovation projects,
pipes and valves are often replaced when the domestic water system is renewed. In this case, the one-way valve in the network will also be renewed,
through which the increase in pressure has previously been able to escape to other parts of the network. Therefore, the safety valve drops more in
renovation sites than before. Water density is at its highest at + 4 °C. When the temperature is raised or lowered, the volume of water increases. The
coefficient of thermal expansion of the water volume when increasing the temperature from +4 °C to +80 °C shall be 0,0290:
1 Kg H2O (water) + 4 °C at = 1 litre
1 Kg H2O (water) + 80 °C = 1,0290 liter
E.g. 300 kg of water at + 4 °C = 300 liters
300 kg water at + 80 °C = 308,7 litres
In the example, the volume increases by 8.7 litres and this amount is removed through the safety valve.
E.G. 50 kg of water + 4 °C = 50 liters of 50 kg of water at + 80 °C = 51,45 litres

10 / 16
In example 2, 1.45 l is removed respectively.
The examples are used to illustrate how much water expands as it heats up, and thus how much water can be removed through the safety valve in 24
hours. If this expanded part of the water cannot escape through the safety valve, the pressure in the system will rise so high that eventually the
weakest point in the network will fail and cause water damage.
GUARANTEE
The warranty of the tank is 2 years, for components 1 year.
The warranty does not apply to situations where the operating and installation instructions have been followed.
RECYCLING
When removing the appliance from service, it must be agreed with a qualified installer that the appliance will be delivered to an appropriate and
authorised recycling station.
