Connection on Heat Source Side | Dimplex SI 9CS, SI 17CS, SI 7CS

7.3 Connection on Heat Source Side

The following procedure must be observed when making the connection:

Connect the brine line to the flow and return pipe of the heat pump.

CAUTION! The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress of impurities.

In addition, a powerful vent must be installed at the highest point of the heat source system. The hydraulic plumbing diagram must be observed here.

The brine liquid must be produced prior to charging the system. The brine concentration must be at least 25 %. Freeze protection down to -14°C can thus be ensured.

Only antifreeze products on the basis of mono- ethylene glycol or propylene glycol may be used.

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

CAUTION! The brine solution must contain at least 25 % of an antifreeze and corrosion protection agent on a monoethylene glycol or propylene glycol basis.

7.4 Electrical Connection

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

-Connection of the control wire to the control panel of the heat pump via terminals X1: L/N/PE.

-Connection of the load wire to the control panel of the heat pump via terminals X5: L1/L2/L3/PE.

-Connection of the brine pump (to be provided by the customer) to the control panel of the heat pump via terminal X1: PE and pump contactor K2: 2/4/6 (.. 5-17CS), or motor protection F7: 2/4/ 6 (.. 21CS).

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

For detailed instructions concerning the connection and functioning of the heat pump controller refer to the operating manual supplied with the controller.

MOUNTING

An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company disable contac- tor or power contactor) as well as a 3-pole circuit breaker with simultaneous tripping of all external conductors must be provided . The required cross- sectional area of the conductor is to be selected according to the power consumption of the heat pump, the technical connection requirements of the relevant utility company and all applicable regula- tions. Power consumption data of the heat pump is provided in the product literature and on the nameplate. The terminals are designed for a max. conductor cross-section of 10 mm˝.

CAUTION! The clockwise phase sequence must be observed when connecting the load line (the heat pump will deliver no output and will be very noisy when the phase sequence is in- correct).
