7 START UP Before start‐up

• Ensure the availability of diagrams and manuals of the installed appliance. • Check the availability of diagrams electrical and hydraulic diagrams of the plant where the appliance is connected. • Check if the anti‐vibration couplings exists on hydraulic pipes. • Check if the shut‐off valves of the hydraulic circuits are opened. • Check that the hydraulic circuit has been loaded into required pressure and vented from air. • Check that all the hydraulic connections are carried out correctly and that all information on the labels are respected. • Ensure that arrangements have been provided to drain condensate. • Ensoure that power cables and all terminals anre well connected. • Check that the electrical connections have been made according to applicable regulations including grounding. • The voltage must be specified on the nameplate of the unit. • Ensure that the voltage is within the tolerance limits of (±10%). • Check that the heating elements of the compressor are powered properly. • Ensure that there are no gas leaks. • Before the start up, check that all shutting panels are positioned and fixed with proper screws.

The crankcase heaters have to be powered at least 12 hours before start up by switching off the main switch (the heaters are automatically powered when the main switch is switched off). The crankcase heaters are working properly if, after some minutes, the temperature of crankcase’s compressor is about 10°C ÷ 15°C higher than ambient temperature. Never switch off the unit (for a temporary stop) by switching off the main switch: this component should be used to disconnect the unit from the power supply only for lengthy stoppages (e.g. seasonal stoppages). Besides, failing the power supply, the crankcase’s resistances are not supplied thus resulting in a possible breakdown of the compressors once the unit is switched on.

WARNING Do not modify the internal wiring of the unit otherwise the warranty will terminate immediately. WARNING: As for the heat pump models, the summer/winter operating mode have to be selected at the beginning of the related season. Frequent changes of this seasonal operating mode have to be avoided in order to prevent severe damages to compressors.

8.8 ADJUSTMENT OF SANITARY WATER VALVE

To activate the sanitary hot water you must: • connect to the terminals IA2 –G a sensor which should be installed inside the tank, • connect the 3‐way switch‐over valve to the terminals UD1‐N (with spring return) If the sanitary hot water temperature is lower than the set‐point of sanitary water (set to 48°C by default) the unit activates the 3‐way switch‐over valve to deviate the flow of water towards the water tank or to a heat exchanger. If the set‐point of sanitary water is reached, the valve returns in rest period. Contact UD1 N‐(3‐way valve): • close: valve energized and water flow deviated to the water tank, • open: valve de‐energized and water flow deviated to the user. Commutating from winter mode operation to sanitary mode operation, the compressor remains on and works under the set frequency. Commutating from summer mode operation, the compressor turns off for safety period.

NOTES: Using the keyboard on the unit to turn off it does not the sanitary operation The display board on the unit shows: • In sanitary mode: the display shows the temperature measured by the sensor located in the container, • In heating or cooling mode: the diplay shows the outlet water temperature sensor.

11.1 ENVIRONMENTAL PROTECTION

According to the norms dealing with the use of depleting stratospheric ozone substances, it is forbidden to release refrigerants fluids in the atmosphere. They have to be collected and delivered to the seller or to proper gathering points at the end of their operating life. Refrigerant R410A is mentioned among controlled substances and for this reason it has to be subjected to the mentioned norms. A particular care is recommended during service operations in order to reduce as much as possible any refrigerant loss.

12 WHEN THE UNIT GOES OUT OF SERVICE Once the unit is arrived at the end of its life cycle and needs to be removed or replaced, the following operations are

recommended. • the refrigerant has to be recovered by trained people and sent to proper collecting centre; • compressors’ lubricating oil has to be collected and sent to proper collecting centre; • the frame and the various components, if not serviceable any longer, have to be dismantled and divided according to their nature, particularly copper and aluminium, which are present in conspicuous quantity in the unit. These operations allow easy material recover and recycling process, thus reducing the environmental impact.

17 OPERATION LIMITS 17.1 Evaporator water flow rate

The nominal water flow rate is referred to a ∆T = 5°C, between the evaporator’s inlet and outlet temperatures. The allowed maximum flow rate is corresponding to ∆T = 3°C; higher values may cause too high pressure drops. The allowed minimum water flow rate is corresponding to ∆T = 8°C. Insufficient values may cause too low evaporating temperatures with the intervention of safety devices which would stop the unit and, in some particular cases, the water can freeze in the evaporator coil causing the refrigeration circuit to break down. We enclosed below a most accurate table showing the minimum flow rates that to ensure for the plate heat exchanger for a the proper operation of unit according to the model (note: the water flow switch is used for preventing the freezing sensor from failure in the case of insufficient water flow but it does not ensure the minimum flow rate required in order the unit can work properly)

Model

Cooling capacity for reference [kW] 6,12 8,12 11,90 14,07

Minimum water flow rate that to ensure [L/s] 0,183 0,243 0,356 0,421 As a first approch, and in the absence of other detection systems, the proper flow rate for getting the best performance from your unit can be found at maximum speed of the circulator, using the pressure gauges for controlling the pressure difference between the return and the delivery water on the outside water connections of the unit and make sure that such value is equal or less than the static pressure indicated on the curves shown in paragraph 16 for the respectives models.

17.2 Cold water temperature (summer operation)

The allowed minimum temperature at the evaporator’s outlet is 5°C; for more lower temperatures, the unit should undergo some necessaries structural modifications. In this case contact our company for the feasibility study and evaluation of changes to be made according to your requests. The maximum temperature that can be maintained at the outlet of the evaporator is 25°C. Higher temperatures (up to a maximum of 40°C) can anyway be tolerated during transitions and start‐up phases of the system. In all cases, the maximum electrical input occurs for the heat pump operating mode at a water outlet temperature of 55°C and with outdoor temperature of ‐10°C (see the tables in paragraph 17.3).

17.3 Hot water temperature (winter operation)

Once the system is working at the right temperature, the inlet hot water temperature should not to be lower than 25°C; the lowest values that are not related to transitional or start‐up stages may cause compressor’s incorrect working operation and its possible related breakdown. The maximum outlet water temperature have not to exceed 55°C. As a function of the maximum input power and the consequent performance decrease in terms of C.O.P. outlet temperature of the water up to 55°C with outdoor air temperature up to 5°C are basically recommended. The water outlet temperature may be reduced for lower temperatures of the outdoor air temperature, this is according to the conditions of use, taking account of the consumption values indicated in the tables below for the maximum input power as a function of the outdoor temperature and the produced water. For higher temperatures than those pointed out, especially if have a concomitant with the reduction of the water flow rate, it may cause abnormalities to the normal operating of the unit, or the safety devices act in critical cases.

17.4 Ambient air temperature

The units are designed and manufactured to operate, in summer operation, with the condensate control, with outdoor air temperatures ranging between ‐10°C and 46°C. While operating as a heat pump, the admitted outdoor air temperatures range from ‐15°C to 40°C as a function of the water outlet temperature as indicated in the below table.

The water flow rate and pressure drop correction factors are to be applied directly to the values given for operation without glycol. The water flow rate correction factor is calculated in order to get the same temperature’s difference that would be obtained without glycol. The pressure drop’s correction factor takes into account the different water flow rate obtained from the application of the water flow rate correction factor.
