RXYSQ4PA7V1B RXYSQ4PA7Y1B RXYSQ5PA7V1B RXYSQ5PA7Y1B RXYSQ6PA7V1B RXYSQ6PA7Y1B CONTENTS Page READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION. KEEP THIS MANUAL IN A HANDY PLACE FOR FUTURE REFERENCE. 1. Safety considerations ................................................................ 1 2. Introduction................................................................................ 2 2.1. 2.2. 2.3. 2.4.
■ ■ ■ ■ ■ ■ Make certain that all electrical work is carried out by qualified personnel according to the local laws and regulations and this installation manual, using a separate circuit. Insufficient capacity of the power supply circuit or improper electrical construction may lead to electric shocks or fire. Make sure that all wiring is secure, using the specified wires and ensuring that external forces do not act on the terminal connections or wires. Incomplete connection or fixing may cause a fire.
3. BEFORE INSTALLATION 1 Select an installation site where the following conditions are satisfied and that meets with your customer's approval. - Places which are well-ventilated. - Places where the unit does not bother next-door neighbours. - Safe places which can withstand the unit's weight and vibration and where the unit can be installed level. - Places where there is no possibility of flammable gas or product leak. - Places where servicing space can be well ensured.
The outdoor unit may short circuit depending on its environment, so use the louvers (field supply). 8 If you install the unit on a building frame, please install a waterproof plate (within 150 mm of the underside of the unit) or use a drain plug kit (option) in order to avoid the drain water dripping. 5.1. Installation method for prevention of falling over If it is necessary to prevent the unit from falling over, install as shown in the figure.
(C) In case of multiple-row installation (for roof top use, etc.) If drain holes of the outdoor unit are covered by a mounting base or by floor surface, raise the unit in order to provide a free space of more than 100 mm under the outdoor unit. NOTE 1. In case of installing one unit per row. ≥100 ≥2000 ≥200 ≥1000 2. 6. INSTALLATION In case of installing multiple units (2 units or more) in lateral connection per row.
7.1. ■ Selection of piping material Always use the supplied copper gasket when connecting the gas pipe supplied with the unit. See "9. Refrigerant piping" on page 7. ■ Foreign materials inside pipes (including oils for fabrication) must be ≤30 mg/10 m. ■ Construction material: phosphoric acid deoxidized seamless copper for refrigerant. 8.1. ■ Temper grade: use piping with temper grade in function of the pipe diameter as listed in table below.
For RXYSQ6 only You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may follow the installation method mentioned below. NOTE The size of the gas side stop valve is Ø15.9 while the inter-unit piping is Ø19.1. Use the standard supplied accessory piping to make the connection. See figure 15. After the work is finished, make sure to check that there is no gas leak.
■ For cooling operation under low ambient temperature or any other operation under low pressure, apply silicon pad or similar to prevent freezing of the gas stop valve flare nut (see figure). Freezing of the flare nut may cause refrigerant leak. Silicon sealing pad (Make sure there is no gap) 9.3. Opening the valve 1. 2. ■ Be sure to insulate the liquid and gas-side field piping and the refrigerant branch kit. Any exposed piping may cause condensation or burns if touched.

9.7. Leak test and vacuum drying The units were checked for leaks by the manufacturer. See figure 6 and refer to "Additional refrigerant charge" on page 10 for nomenclature of the parts in figure 6. • Confirm that the gas and liquid line stop valves are firmly closed before pressure test or vacuuming. • Make sure that valve A is completely open.

During automatic refrigerant charging, the remote controller indicates (test operation) and (external control).
........................... Functional earthing ■ To avoid compressor breakdown. Do not charge the refrigerant more than the specified amount. ■ If the total refrigerant cannot be charged while the outdoor unit is at a standstill, it is possible to charge the refrigerant by operating the outdoor unit using the refrigerant charge function (refer to "Setting mode 2" on page 18) and follow "Procedure 3: Charging while the outdoor unit is operating" on page 13. ..........................

Thermistor (M1C discharge) ■ Before obtaining access to terminal devices, all supply circuits must be interrupted. R4T................ * ..... Thermistor (heat exchanger) ■ Use only copper wires. R4T................ # ..... Thermistor (subcool) ■ Do not turn on the main switch until all the wiring is completed.
11.4. Connecting power wire and transmission wires 11.5. Power circuit and cable requirements ■ Let the power wire (including ground wire) go through the power outlet port on either the front, side or back of the outdoor unit. ■ Let the transmission wires go through the cable outlet port, pipe outlet port or knock out hole on either the front, side or back of the outdoor unit. (See figure 9). A power circuit (see table below) must be provided for connection of the unit.
Precautions when laying power wiring For low-noise operation or demand operation, it is necessary to get the optional 'External control adaptor for outdoor unit' (DTA104A61/62). Use round pressure terminals for connections to the power terminal block. For details, see the installation manual attached to the adaptor. When none are available, follow the instructions below. ■ Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause abnormal heat.
12. BEFORE OPERATION Play it safe! Touch a metal part by hand (such as the stop valve) in order to eliminate static electricity and to protect the PCB before performing service. 12.1. Service precautions WARNING: ELECTRIC SHOCK 12.2. Checks before initial start-up Caution when performing service to inverter equipment ■ Do not touch live parts for 10 minutes after the power supply is turned off because of high voltage risk.

■ 5 12.5. Checks in normal operation Indoor units cannot be checked individually. After the test operation is finished, check the indoor units individually via the remote controller. Set the master unit (= indoor unit having the right to select the cooling/heating operation mode). ■ The led indication changes during this operation, but that is not abnormal. In case of wired remote controllers ■ Please attach the front plate of the outdoor unit in order to prevent electric shocks.
13. SERVICE 14.2. Maximum concentration level MODE OPERATION After turning on the power supply, the unit can not be started until the H2P initialisation led, indicating that the unit is still under preparation, goes off (maximum 12 minutes). The unit of measurement of the concentration is kg/m 3 (the weight in Vacuuming method At the first installation, this vacuuming is not required. It is required only for repair purposes.
2 Calculate the smallest room volume (m3) In a case such as the following, calculate the volume of (A), (B) as a single room or as the smallest room. A. Where there are no smaller room divisions B. Where there is a room division but there is an opening between the rooms sufficiently large to permit a free flow of air back and forth.
