3 INSTALLATION INSTRUCTIONS
3.1 Hydraulic installation
The DHW circuit of the tank is prepared for permanent connection to the mains water supply through
the cold-water inlet. For more information in this area, please refer to the “Technical Characteristics”
section, where the maximum pressures are indicated.
The hydraulic installation must be made by qualified technicians, in compliance with current
installation regulations and taking the following recommendations into account:
- The secondary circuit (or domestic hot water circuit) must be equipped with a safety valve,
calibrated to a maximum of 0.7 MPa (7 bar)
- The evacuation of the safety valve should always be led to the drain. The drainage pipes should
be kept open to the atmosphere. The “Maintenance” section should be followed to ensure the
proper functioning of the device.
- To avoid the continuous dripping of the DHW safety valve, it is advisable to install an DHW
expansion vessel.
- The primary circuit (or heating circuit) should be fitted with a safety valve, calibrated to a
maximum of 0.3 MPa (3 bar).
- Place dielectric sleeves in the connections of the secondary circuit.
- When the cold water pressure is higher than the design pressure of the appliance, a calibrated
pressure reducer must be installed at a value not higher than the design pressure.
- To avoid heat losses through the hot water pipe in the tank installation, an anti thermosiphon
should be installed at the outlet of the tank. The hot water pipe should be heat-insulated (at least
until the inlet of the anti thermosiphon).
3.2 Location
The tank should not be installed outdoors or in a place where it can be exposed to inclement
weather.
For better energy use, the tank should be installed as close as possible to the hot water generator.
When choosing the location, the weight of the filled tank should be taken into account, and it must
be protected against frost. The pipes should have thermal insulation in accordance with current
regulations
3.3 Equipment / options
Although the BT TRIO devices are equipped with all the necessary components for their operation,
DOMUSA TEKNIK has found it interesting to offer several optional components for cases in which
special features are required.
