SAFETY PRECAUTIONS The precautions listed here are divided into the following types.They are quite important, so be sure to follow them carefully. Meanings of DANGER, WARNING, CAUTION and NOTE symbols. DANGER Indicates an imminently hazardous situation which if not avoided, will result in death or serious injury. WARNING Indicates a potentially hazardous situation which if not avoided, could result in death or serious injury.
Page 8 SAFETY PRECAUTIONS DANGER Before touching electric terminal parts, turn off power switch. When service panels are removed, live parts can be easily touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed. Do not touch water pipes during and immediately after operation as the pipes may be hot and could burn your hands.
Page 9 CAUTION • Ground the unit. • Grounding resistance should be according to local laws and regulations. • Do not connect the ground wire to gas or water pipes, lightning conductors or telephone ground wires. • Incomplete grounding may cause electric shocks. −...

Page 44 WATER CONNECTIONS Air purge valve Remaining air in the water circuit will be automatically removes air from the water circuit. Backup heater(optional) Provides additional heating capacity when the heating capacity of the heat pump is insufficient due to very low outdoor temperature. Also protects the external water piping from freezing.
Page 45 Check the water circuit The units are equipped with a water inlet and outlet for connection to a water circuit. The units should only be connected to closed water circuits. Connection to an open water circuit would lead to excessive corrosion of the water piping. Only materials complying with all applicable legislation should be used.
Page 46 WATER CONNECTIONS NOTE In most applications this minimum water volume will be satisfactory. In critical processes or in rooms with a high heat load though, extra water might be required. When circulation in each space heating loop is controlled by remotely controlled valves, it is important that this minimum water volu- me is kept even if all the valves are closed.
Page 47 Example 1： The unit (16kW) is installed 10m below the highest point in the water circuit. The total water volume in the water circuit is 50 L. In this example, no action or adjustment is required. Example 2： The unit(16kW) is installed at the highest point in the water circuit. The total water volume in the water circuit is 150 L. Result: 1.
Page 48 WATER CONNECTIONS NOTE The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping: • Never use Zn-coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the unit's internal water circuit.

Page 50 WATER CONNECTIONS NOTE Be aware of the hygroscopic property of glycol. It absorbs moisture from the environ-ment. Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concentration is then lower and the water could freeze. Preventive actions must be taken to ensure minimal exposure of the glycol to air.
Page 51 Piping insulation The complete water circuit including all piping, must be insulated to prevent: • condensation during cooling operation • reduction of the heating and cooling capacity • freezing of the outside water piping during winter. The thickness of the sealing materials must be at least 13 mm with λ= 0.039 W/mK in order to prevent freezing on the outside water piping.

13 TROUBLE SHOOTING This section provides useful information for diagnosing and correcting certain troubles which may occur in the unit. This troubleshooting and related corrective actions may only be carried out by your local technician. General guidelines Before starting the troubleshooting procedure, carry out a thorough visual inspection of the unit and look for obvious defects such as loose connections or defective wiring.
Page 102 13 TROUBLE SHOOTING The unit is turned on but the compressor is not starting (space heating or domestic water heating) POSSIBLE CAUSES CORRECTIVE ACTION In case of low water temperature, the system utilizes the backup heater to reach the minimum water temperature first (12°C).
Page 103 Space heating capacity shortage at low outdoor temperatures Check that the "OTHER HEATING SOURCE/ BACKUP HEATER"is enabled, see chapter 9 Start-up and configuration - OTHER HEATING SOURCE. Check whether or not the thermal protector of the backup heater has been activated (see chapter to Backup heater operation is not Electronic board layout - main control board to thermal protector of the backup heater for location of activated.
