7 Installation

7.1General Information

The following connections need to be established on the heat pump:

„Flow and return flow of the brine system

„Flow and return flow of the heating system

„Power supply

7.2Heating System Connection

ATTENTION!

Flush the heating system prior to connecting the heat pump.

Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down.

Once the heating system has been installed, it must be filled, de- aerated and pressure-tested.

The sensors which are delivered already connected and loosely placed in the switch box must be mounted and insulated accord- ing to the block diagram.

7.3Heat Source Connection

The following procedure must be observed when connecting the heat source:

Connect the brine pipe to the heat pump flow and return. The hy- draulic plumbing diagram must be adhered to.

ATTENTION!

The supplied dirt trap must be inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities.

In addition, a micro bubble air separator must be installed in the heat source system.

The brine liquid must be produced prior to charging the system. The liquid must have an antifreeze concentration of at least 25 % to ensure frost protection down to -14 °C.

Only monoethylene glycol or propylene glycol-based antifreeze may be used.

The heat source system must be de-aerated and checked for leaks.

ATTENTION!

The brine solution must contain at least a 25 % concentration of a monoethylene glycol or propylene glycol-based antifreeze, which must be mixed before filling.

English

Minimum heating water flow rate

The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing either a manifold without differential pressure or an overflow valve. The procedure for adjusting an overflow valve is described in the Chapter Start-Up.

Antifreeze protection for installation locations prone to frost

The antifreeze function of the heat pump controller is active whenever the controller and the heat circulating pumps are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. The heat- ing circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power fail- ure can not be detected (holiday home).

7.4Electrical Connection

The following electrical connections must be established on the heat pump:

„Connection of the control line to the control panel of the heat pump via terminal X1: L/N/PE.

„Connection of the mains cable to the control panel of the heat pump via terminal X6: L/N/PE.

„Connection of the brine circulating pump (to be provided by the customer) to the control panel of the heat pump via ter- minal X1: PE and pump contactor K5: 14/24. As an option, the brine pump can also be directly connected (see terminal connection plan).

All electrical components required for the operation of the heat pump are located on the control panel.

For detailed instructions concerning the connection and function- ing of the heat pump controller (e.g. external wall sensor included in the scope of supply) refer to the operating manual supplied with the controller.

A disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) as well as a 1-pole circuit breaker have to be provided by the customer. The re- quired conductor cross-section is to be selected according to the power consumption of the heat pump, the technical connection requirements of the respective utility company as well as all ap- plicable regulations. Details on the power consumption of the heat pump are listed on both the product information sheet and the type plate. The connection terminals are designed for a max.

conductor cross-section of 10mm2.

SI7MER, SI 11MER, SI 9MER, SI 5MER specifications

The Dimplex SI series is an impressive range of high-performance electric storage heaters designed for modern living while prioritizing energy efficiency and comfort. This line includes models SI 5MER, SI 7MER, SI 9MER, and SI 11MER, each tailored to meet various heating needs and room sizes.

One of the standout features of the Dimplex SI series is its innovative storage technology. These heaters work by storing heat during off-peak hours, when electricity costs are lower, and releasing it throughout the day. This characteristic not only helps in reducing energy bills but also provides a stable and comfortable heat output regardless of external temperature fluctuations.

The SI 5MER model is designed for smaller spaces, providing an efficient heating solution for apartments or compact rooms. The digital controls allow users to set desired temperatures easily, while the advanced thermal insulation minimizes heat loss.

Moving to the SI 7MER, this model offers a higher output suitable for slightly larger areas. It incorporates similar technology and features as the SI 5MER but with increased heat retention capacity, ensuring that spaces remain warm during colder months.

The SI 9MER takes performance up a notch, catering to medium-sized rooms. It includes a larger storage capacity and enhanced insulation, ensuring that warmth is dissipated gradually and evenly throughout the day. The integrated digital display allows for precise control, enhancing user convenience.

For those requiring even more power, the SI 11MER is the ideal option. It is perfect for larger living spaces and features advanced energy efficiency technologies. With a robust design, this model not only functions effectively but also features a sleek and modern aesthetic that can complement any interior.
