OPTIONAL ACCESSORIES
In order to complete the features offered by the
FUSION
hydraulic tank module,
DOMUSA TEKNIK
offers a wide range of optional accessories that can be integrated
inside
it. The following sections
describe the correct assembly and connection of these accessories.
5.1
Assembly and connection of a backup heater for DWH (E1)
The
FUSION
hydraulic module allows the assembly of a heating heater for DHW in the outlet
provided for this in the storage tank. With this heater, it will be possible to obtain Domestic Hot
Water production temperatures exceeding 50 ºC, enabling the necessary temperatures to be
reached for the correct execution of the function for protection against Legionella bacteria. For the
assembly, remove the socket cap and seal the heater on it:
1.-
Disassemble and remove the plug from the socket
indicated in the figure.
2.-
Assemble the heater supplied with the kit in its place,
making sure to seal it correctly.
3.-
Connect the power cable, supplied with the kit, to the Dual
Clima heat pump.
The electrical connection of the heater will be made between terminals
E1L
and
E1N
(neutral) of
the
DUAL CLIMA
heat pump components. To do this, an electrical hose (supplied in the DOMUSA
TEKNIK heater kit) should be carried from the
FUSION
module to the heat pump, located on the
outside. The hydraulic module has a series of cable ducts in its roof, through one of which it will be
possible to remove the hose from inside the equipment.
The relay that activates the electrical heater has a maximum capacity of 20 A of consumption.
Therefore, to connect heaters exceeding 4,500 W, a contactor should be interposed between the
terminals of the power terminal and the heater.
IMPORTANT: When working on the electrical installation of the heat pump, make sure that it is
disconnected from the electrical network.
