Where the corrosion of copper pipes or welded parts can lead to refrigerant leaks.

  • Page 13: General Introduction

    GENERAL INTRODUCTION. - Magis M4-30 block heat pumps are used both for heating and cooling applications and for domestic hot water tanks. They can be cou- pled with fan coils, floor heating applications, low-temperature high-efficiency radiators, domestic hot water tanks and solar kits. - The unit is supplied with a control panel.

  • Page 14: Cooling Mode

    Solar control unit (optional) A solar control unit can be connected to the unit for the production of domestic hot water with thermal solar system, with relative coil inside the storage tank. The unit has a freezing prevention function using the heat pump to keep the water system safe from freezing in all conditions. Since a power failure could occur while the unit is unattended, it is recommended to empty the system (if there is no glycol in the water) (see par- agraph “Anti-freeze protection of water circuit.“...

  • Page 152 a) During repairs of sealed components, all power supplies must be disconnected from the appliance in operation before removing the sealed covers, etc. If it is absolutely necessary that the appliance be energised during maintenance, a permanently operated leak detec- tion device must be used, at the most critical point, to prevent a potentially hazardous situation.
  • Page 153 Before performing this operation, the technician must have extensive knowledge of the appliance and all its details. It is good practice that the refrigerant be recovered correctly. Before performing the intervention, an oil and refrigerant sample must be withdrawn. If an analysis needs to be performed before recovering the refrigerant, power must be available. a) Become acquainted with the appliance and its operation.
