User manual TOSHIBA RBC-TWP101E INSTALLATION MANUAL

[. . . ] Follow the Owner's Manual to explain how to use and maintain the unit to the customer. · Turn off the main power supply switch (or breaker) before the unit maintenance. · Ask the customer to keep the Installation Manual together with the Owner's Manual. WARNING · EN Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner. Inappropriate installation may result in water leakage, electric shock or fire. [. . . ] Conform to the regulations of the local electric company when wiring the power supply. Inappropriate grounding may cause electric shock. Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas. If a combustible gas leaks, and stays around the unit, a fire may occur. CAUTION New Refrigerant Air conditioner Installation · THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER. · The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1. 6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle. · To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the outdoor unit and installation tools are changed from those for the conventional refrigerant. · Accordingly the exclusive tools are required for the new refrigerant. (R410A) · For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it. · The two indoor units of TOSHIBA simultaneous twin packaged air conditioning system are the same units. EN 3 Branch Kit 1:2 · Set and install the header and follower units taking the installation site into consideration. (Be certain to use the new refrigerant R410A in the indoor units. ) The indoor unit connected to the remote controller will be the main unit. Wiring · TO DISCONNECT THE APPLIANCE FROM MAIN POWER SUPPLY. · This appliance must be connected to the main supply by means of a switch with a contact separation of at least 3 mm. · The remote controller cannot be connected to both of the two indoor units (header and follower units). Connect it only to the indoor unit that will become the header indoor unit (Unit A). Connecting the remote controller to the follower indoor unit will cause malfunction. Refrigerant Piping (Branch piping system is used for refrigerant piping) · Compared with R22, pressure of R410A is about 1. 6 times. Unless the piping is installed correctly, gas leak may be caused during operation such as pressure boosting. [. . . ] Automatic address While automatic addressing, the operation can not be performed on the remote controller. When power will be turned on after finish of automatic addressing; · It will require Max. 3 minutes) that outdoor unit starts operation after power was on. EN 12 EN Branch Kit 1:2 5 PIPING HEAT INSULATION Thermal insulation was produced locally. Be certain to thermally insulate the piping both on the liquid and gas sides. [. . . ]
