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 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. To avoid injury, give the piping time to return to normal temperature or be sure to wear protective gloves.
  • 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 10  Confirm the safety of the installation area ( walls, floors, etc. ) without hidden dangers such as water, electricity, and gas.Before wiring/pipes.  Before installation , check whether the user's power supply meets the electrical installation requirements of unit ( including reliable grounding , leakage , and wire diameter electrical load, etc.
  • Page 11 These units are used for both heating and cooling applications. They can be combined with fan coil units, floor heating applications, low temperature high efficiency radiators, domestic hot water tanks (not supplied) and solar kits (not supplied). A wired controller is supplied with the unit . The unit have a freeze prevention function that uses the heat pump and backup heater (option) to keep the water system safe from freezing in all conditions.
  • Page 12 Not supplied. A domestic hot water tank(with or without booster heater) can be connected to the unit. See table for specific tank. If the tank volume is greater than 240L, the temperature probe (T5) should be installed at a position higher than half of the tank’s height.

  • Page 14 Be sure to confirm the model name and the serial number of the unit. Due to relatively large dimensions and heavy weight, the unit should only be handled using lifting tools with slings. The slings can be fitted into foreseen sleeves at the base frame that are made specifically for this purpose. CAUTION To avoid injury, do not touch the air inlet or aluminum fins of the unit.
  • Page 15 CAUTION There is flammable refrigerant in the unit and it should be installed in a well-ventilated site. If the unit is installed inside, an additional refrigerant detection device and ventilation equipment must be added in accordance with the standard EN378. Be sure to adopt adequate measures to prevent the unit from being used as a shelter by small animals.
