Page 8: Installation Site Requirement
2.2 Installation site requirement This unit is designed for outdoor installation, do not install it in an close space. Please consider the condition as following factors when selecting installation site. The installation site should be large enough and well ventilation. The installation site should be convenient for water drainage. - Page 9 Unità Interna 2.4 Routing the refrigerant lines The outdoor unit is pre-filled with refrigerant R410A. No additional filling is required for lines up to 5 m in length. Minimum line length : 3 m Maximum line length :12 m Max. height differential Indoor to outdoor unit : 10m Line lengths between 5 and 12 m must be topped up with an additional 60 g/m refrigerant R410A.

operation, charge additional R410a refrigerant with specified amount to the unit through the service connector on liquid valve. Be sure to charge the specified amount of refrigerant in liquid state to the liquid pipe. Since R410a is a mixed refrigerant, adding it in gas form may cause the refrigerant composition to change, preventing normal operation. - Page 15 Condensate drainage connector shockproof rubber pads 2.7.2 Design of the store tank in the system 1 - kW is the unit for cooling capacity, L is the unit for (G) minimum water flow volume in the formula.

- Page 16 When ambient temperature lower 5 running cooling mode must be charged antifreeze. Refer to upper parameters for the charged volume. Fouling factors The performance data given refer to conditions with clean evaporator plates (fouling factor=1). For different fouling factors, multiply the figures in the performance tables by the coefficient given in the following table.
