3. PIPING DESIGN 3-1. R410 Piping Material 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. MITSUBISHI ELECTRIC recommends pipe size as Ta ble 3-1, or You shall follow the local industrial standard. Pipes of radical thickness 0.7mm or less shall not be used. Table 3-1. Copper pipe size and radial thickness for R410A CITY MULTI.

3. PIPING DESIGN r 3-2-1. IF 16 ports or less are in use, I.e., if only one BC controller is in use with no sub BC controller. Note1. PQRY systems do not require headers. Note2. Indoor units sized P72-P96 should be connected to a BC controller using the Y-shaped CMY-R160-J joint adapter. These indoor units cannot use the same BC controller ports as other units. (They must use their own individual BC controller port.) Note3.

4. INSTALLATION 4-1. PQRY-P-T(S)HMU/Y(S)HMU’s Installation Install indoors; avoid exposing the unit to outside elements. Do not install in an area where it could be subjected to direct heat. Avoid installing the unit in a location where the operating sound could be an annoyance. Install on a stable, load-bearing surface.

4. INSTALLATION WR2-SERIES SYSTEM DESIGN 4-3. Piping Direction 1. Insulation installation With City Multi WY/ WR2 Series piping, as long as the temperature range of the circulating water is kept to average temperatures year-round (29.4°C[85°F] in the summer, 21.1°C[70°F] in the winter), there is no need to insulate or otherwise protect indoor piping from exposure. You should use insulation in the following situations: • Any heat source piping.
PAGE 33
5. CAUTIONS The installer and/or air conditioning system specialist shall secure safety against refrigerant leakage according to local regulations or standards. The following standard may be applicable if no local regulation or standard is available. R410A refrigerant is harmless and incombustible. The R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation.
