Safety Instructions Safety Instructions This Air to water system - Air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the sys- tem so it operates safely and efficiently. For safe installation and trouble-free operation, you must: ●... - Page 11 Safety Instructions Special Precautions DANGER When Wiring Electrical shock can cause severe personal injury or death. Only a qualified, experienced electrician should attempt to wire this system. ● Do not supply power to the unit until all wiring and tubing are completed or recon- nected and checked.
- Page 12 Safety Instructions DANGER ► Keep the fire alarm and the air outlet at least 1.5 m away from the unit. In moist or uneven locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit.
- Page 13 Safety Instructions When Connecting Refrigerant Tubing DANGER ● When performing piping work, do not mix air except for specified refrigerant (R410A or R32, depending on the outdoor unit model) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high pressure inside the refrigerant cycle.
- Page 14 Safety Instructions When Servicing ● Contact the sales dealer or service dealer for a repair. ● Isolate the electrical supply to the unit (power OFF), before opening the unit to check or repair electrical parts and wiring. ● Keep your fingers and clothing away from any moving parts. ●...

- Page 16 Safety Instructions Check of Density Limit R32 U-200PZH2E8 The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the requirements for installation space of appliance are determined according to the refrigerant charge amount [mc] used in the appliance. The minimum indoor floor space compared with the amount of refrigerant is roughly as follows, in case it is installed in a living area with height factor 1.8: PAW-VP380L must be calculated as wall mounted.

Page 23: Dhw Temperature Layering
DHW Temperature layering DHW Temperature layering The water temperature distribution in the tank is not homogeneous! Due to the thermodynamic properties of the refrigerant, the water is at different temperatures across the tank volume. (Top: discharge gas cooling area Middle: condensing area Bottom subcooling area) This is expected to result in a layering of temperatures. -
