Detailed instructions for use are in the User's Guide.

[. . . ] For installation of indoor units, follow the Installation Manual supplied with the indoor unit. Moreover, as this installation manual includes the important articles concerning the "Machinery" Directive (Directive 2006/42/ EC), please read through the manual and make sure you understand it. After installation, give this Installation Manual, the Owner's Manual and the Installation Manual supplied with the indoor unit to the customer and tell the customer to keep them safe. Prepare an exclusive power source for indoor units, independent to that for outdoor units. [. . . ] Install the outdoor units in order of their capacity codes: A (header unit) B C D When connecting gas pipes to indoor units, use Y-shaped branching joints to keep pipes level. When piping to outdoor units using Outdoor unit connection piping kits, intersect the pipes to the outdoor unit and those to indoor units at a right angle as shown in figure 1 on "6. Do not connect them as in figure 2 on "6. INSTALLATION OF THE OUTDOOR UNIT". · Be sure to apply pressure from the service ports of the packed valves (or ball valves) at the liquid side, gas side and balance pipe side. · An airtight test can only be performed at the service ports at the liquid side, gas side and balance pipe side on header unit. · Close the valves fully at the gas side, liquid side and balance pipe side. As there is a possibility that the nitrogen gas will enter into the cycle of outdoor units, re-tighten the valve rods at the liquid side and balance pipe side before applying pressure. (When using MAP140 or MAP160, you do not have to re-tighten the liquid side valve rod as their valves at the liquid side are ball valves. ) · For each refrigerant line, apply pressure gradually in steps at the liquid side, gas side and balance pipe side. Be sure to apply pressure at the gas side, liquid side, and balance pipe side. WARNING Never use oxygen, flammable gases, or noxious gases in an airtight test.

Make the difference 65m or less if the height difference between outdoor and indoor units (H1) is more than 3m. Make the difference 50m or less if the height difference between indoor units (H2) is more than 3m. · If the specified amount of refrigerant cannot be charged, fully open the valves of the outdoor unit at liquid and gas sides, operate the air conditioner in COOL mode, and then charge refrigerant into service port at the gas side. In this time, choke the refrigerant slightly by operating the valve of the canister to charge liquid refrigerant. · The liquid refrigerant may be charged suddenly, therefore be sure to charge refrigerant gradually.

Stick the enclosed refrigerant label adjacent to the charging and/or recovering location. Clearly write the charged refrigerant quantity on the refrigerant label using indelible ink. Then, place the included transparent protective sheet over the label to prevent the writing from rubbing off. Prevent emission of the contained fluorinated greenhouse gas. Ensure that the fluorinated greenhouse gas is never vented to the atmosphere during installation, service or disposal.
