Thank you very much for purchasing TOSHIBA Air Conditioner. Please read this manual carefully before using your Air Conditioner. ·Be sure to obtain the "Owner's manual" and "Installation manual" constructor (or dealer). [. . . ] · After the above procedure of vacuuming has finished, exchange the vacuum pump with a refrigerant cylinder and advance to the additional charging of refrigerant. 39 Outdoor Unit / INSTALLATION MANUAL [ VOLUME-1 ] Addition of refrigerant After vacuuming work, exchange the vacuum pump with the refrigerant bomb and then start the additional charging work of refrigerant. Calculation of additional refrigerant charge amount Refrigerant charge amount at shipment from the factory does not include the refrigerant for pipe at the local site. For refrigerant to be charged in pipe at the local site, calculate the amount and charge it additionally. NOTE) If the additional refrigerant amount indicates minus as the result of calculation, use the air conditioner without addition of refrigerant. Outdoor unit Model Charging amount (kg) MMY-MAP0801FT8 MMY-MAP1001FT8 14. 0 MMY-MAP1201FT8 Additional refrigerant charge amount at local site = Real length of liquid pipe × Additional refrigerant charge amount per 1m liquid pipe (Table 1) × 1. 3 Example : Additional charge amount R (kg) = {(L1 × 0. 025kg/m) + (L2 × 0. 055kg/m) + (L3 × 0. 105kg/m)} × 1. 3 L1 : Real total length of liquid pipe Ø6. 4 (m) L2 : Real total length of liquid pipe Ø9. 5 (m) L3 : Real total length of liquid pipe Ø12. 7 (m) System : 10HP Table-1 Liquid pipe dia. (mm) Additional refrigerant amount/1m liquid pipe (kg/m) 6. 4 0. 025 9. 5 0. 055 12. 7 0. 105 Charging of refrigerant · Keeping valve of the outdoor unit closed, be sure to charge the liquid refrigerant into service port at liquid side. · If the specified amount of refrigerant cannot be charged, open fully valves of outdoor unit at liquid and discharge/ suction gas sides, operate the air conditioner in COOL mode under condition that valve at suction gas side is a little returned to close side, and then charge refrigerant into service port at suction gas side. In this time, choke the refrigerant slightly by operating valve of the bomb to charge liquid refrigerant. The liquid refrigerant may be charged suddenly, therefore be sure to charge refrigerant gradually. · When refrigerant leaks and refrigerant shortage occurs in the system, recover the refrigerant in the system and recharge refrigerant newly up to the correct level. REQUIREMENT <Entry of refrigerant charge amount> · Fill the additional refrigerant record column of the wiring diagram indication plate with the additional refrigerant amount at installation work, total refrigerant amount and the name of the service man who charged refrigerant at installation time. · The total refrigerant amount means the total value of the refrigerant amount at shipment and the additional refrigerant amount at installation time. The refrigerant amount at the shipment is one described on the "Unit nameplate". 40 Outdoor Unit / INSTALLATION MANUAL [ VOLUME-1 ] 5 · · · · REFRIGERANT PIPING Full opening of valve Open valve of the outdoor unit fully. Using 4mm-hexagonal wrench, open fully the valve rods at liquid sides. Using a spanner, etc, open fully the valve rod of packed valve at suction gas side. Using the pinchers, open fully the handle of the ball valve at gas side. Be careful that handling of ball valve differs from that of packed valve. How to open the ball valve at gas side Valve unit Valve unit Handle position Charge port Handle Pull out the handle and using cutting pliers, etc. (Open fully) Charge port Flare nut Push in handle. Handle Closed completely Opened fully Flare nut Heat insulation for pipe · Apply heat insulation of pipe separately at liquid, suction gas, discharge gas sides. · Be sure to use thermal insulator with heat-resisting temp. 120°C or more. CAUTION · After piping connection work has finished, cover the opening of the piping/wiring panel with the piping cover, or fill silicon or putty in space of the pipes. · In case of drawing-out the pipes downward or sideward direction, also close the openings of the base plate and the side plate. · Under the opened condition, a trouble may be caused due to entering of water or dust. In case of using pipe cover In case of using no pipe cover Piping/wiring panel Piping/wiring panel Drawing-out sideward Drawing-out sideward Drawing-out frontward Close the opening with pipe cover. Drawing-out downward Drawing-out frontward Fill silicon or putty in periphery of the pipes.

If there is capacity shortage of the power circuit or incomplete electric work, a fire or electric shock is caused. For wiring, use the specified wires and connect them securely so that external force of wire does not transmit to the terminal connecting section. If connection or fixing is incomplete, a fire is caused. Be sure to connect the earth wire. Grounding work is necessary based upon a law. If the earth grounding is incomplete, an electric shock is caused. [. . . ] Connect the connector (green) of the attached wire (control wiring) to CN02 on the control P. C. Secure the two attached wires with the attached cord clamp. (Be careful not to apply tension to the wires and connectors. ) · Check that the wires are not pinched, and then attach the cover.
