3. Selecting an installation site & Accessories • Select a site with sturdy fixed surface sufficiently durable against the weight of unit. • Before installing unit, the routing to carry in unit to the installation site should be determined. • Select a site where the unit is not affected by entering air. • Select a site where the flow of supply and return air is not blocked. • Select a site where refrigerant piping can easily be led to the outside.
6. Refrigerant piping work 6.1. Refrigerant pipe [Fig. 6-5] (P.3) a Flare nut b Copper tube [Fig. 6-1] (P.3) a Indoor unit b Outdoor unit Refer to the Instruction Manual that came with the outdoor unit for the restrictions on the height difference between units and for the amount of additional refrigerant charge. • Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. (not possible to put them on after flaring work) 6.2.4. Flaring work [Fig.
6. Refrigerant piping work 1.Remove and discard the rubber bung which is inserted in the end of the unit piping. Tighten the cap to the service port to obtain the initial status. 2.Flare the end of the site refrigerant piping. 3.Pull out the thermal insulation on the site refrigerant piping and replace the insulation in its original position.
7. Duct work • • • • Connect canvas duct between unit and duct. [Fig. 7-1] (P.5) Use incombustible material for duct parts. Provide full insulation to inlet duct flange and outlet duct to prevent condensation. Be sure to change the position of air filter to a position where it can be serviced.
8. Electrical work 8.1. Power supply 8.1.1. Indoor unit power supplied from outdoor unit 8.1.2. Separate indoor unit/outdoor unit power supplies (For PUHZ application only) The following connection patterns are available. The outdoor unit power supply patterns vary on models. The following connection patterns are available. The outdoor unit power supply patterns vary on models. 1:1 System 1:1 System * The optional wiring replacement kit is required.

8. Electrical work 8.2. Indoor wire connection [Fig. 8-5] (P.7) Work procedure 1.Remove 2 screws to detach the electric component cover. 2.Route each cable through the wiring intake into the electric component box. (Procure power cable and in-out connecting cable locally and use remote control cable supplied with the unit.) 3.Securely connect the power cable and the in-out connecting cable and the remote control cable to the terminal blocks. 4.
8. Electrical work 8.4.2. Signal Receiving Unit [Fig. 8-11] (P.8) 1) Sample system connection [Fig. 8-7] (P.8) Only the wiring from the signal receiving unit and between the remote controllers is shown in [Fig. 8-7]. The wiring differs depending on the unit to be connected or the system to be used. For details on restrictions, refer to the installation manual or the service handbook that came with the unit. 1. Connecting to Mr.
8. Electrical work 8.5. Function settings (Function selection via the remote controller) 2) For wireless remote controller [Fig. 8-22] (P.11) 1. Changing the external static pressure setting. 8.5.1 Function setting on the unit (Selecting the unit functions) • Be sure to change the external static pressure setting depending on the duct and the grill used. 1) For wired remote controller [Fig. 8-21] (P.11) 1. Changing the external static pressure setting.
9. Test run 9.1. Before test run 9.2. Test run After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply. Use a 500-volt megohmmeter to check that the resistance between the power Ω. supply terminals and ground is at least 1.0 MΩ Do not carry out this test on the control wiring (low voltage circuit) terminals. Warning: Ω.
9. Test run 9.3. Test run 9.3.1. Using wireless remote controller (option) [Fig. 9-3] (P.11) 1 Turn on the power to the unit at least 12 hours before the test run. 2 Press the TEST RUN button A twice continuously. (Start this operation from the status of remote controller display turned off.) TEST RUN and current operation mode are displayed. 3 Press the MODE button B to activate COOL mode, then check whether cool air is blown out from the unit.
9. Test run On the wireless remote controller with conditions above, following phenomena takes place. • No signals from the remote controller are accepted. • OPE lamp is blinking. • The buzzer makes a short ping sound. Note: Operation is not possible for about 30 seconds after cancellation of function selection. (Correct operation) For description of each LED (LED1, 2, 3) provided on the indoor controller, refer to the following table.
