3. PIPING DESIGN Refrigerant pipe for CITY MULTI shall be made of phosphorus deoxidized copper, and has two types. A. Type-O : Soft copper pipe (annealed copper pipe), can be easily bent with human's hand. B. Type-1/2H pipe : Hard copper pipe (Straight pipe), being stronger than Type-O pipe of the same radical thickness. The maximum operation pressure of R410A air conditioner is 4.30 MPa [623psi] . The refrigerant piping should ensure the safety under the maximum operation pressure.

If the A/C system is designed to use Cooling-mode under Outside temperature 10°C [50°F], H'<=40m [131ft.]; Note3. As bents cause pressure loss on transportation of refrigerant, fewer bents design is better; Piping length needs to consider the actual length and equivalent length which bents are counted. Equivalent piping length = Actual piping length + "M" x Quantity of bent.

Refrigerant Charge Calculation (1) Calculation of additional refrigerant charge Calculate the amount of additional charge based on the length of the piping extension and the size of the refrigerant line. Use the table to the below as a guide to calculating the amount of additional charging and charge the system accordingly. If the calculation results in a fraction of less than 0.1kg, round up to the next 0.1kg. For example, if the result of the calculation was 12.

Tilting the twinning pipe more than specified will cause damage to the unit. The length of the straight part of the pipe before the branching For the twinning kit, always use the accessory piping parts. The length of the straight part of pipe connected in front of the twinning pipe must be 500 mm (19 in) or longer.

Low Ambient Kit Application Guidelines General Unit Placement and Clearances Top View 2010 H2i ® Y-SERIES SYSTEM DESIGN • Outdoor units should be located in an area protected from prevailing winds. • In high wind locations, it may be advisable to install the outdoor units within a walled area. • Hood discharge should be directed away from or perpendicular to the prevailing winds. Do not direct the hood discharge towards prevailing winds.

4. OUTDOOR INSTALLATION 2010 H2i ® Y-SERIES SYSTEM DESIGN Additional Rooftop Mounting Guidelines Ground-level installation is preferred for outdoor units that include a low ambient kit. If ground-level installation is not possible, follow general, as well all additional installation guidelines for rooftop mounting. If you have any questions, please contact your distributor. Note: Low ambient hood(s) increase the overall height of the outdoor units and make them more susceptible to wind stresses.

6. CAUTIONS 2010 H2i ® Y-SERIES SYSTEM DESIGN The installer and/or air-conditioning system specialist shall follow local safety regulations and standards regarding refrigerant leakage. The following standard may be applicable if a local regulation or standard is available. 6-1. Refrigerant Properties R410A refrigerant is harmless and incombustible. R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation.
