Notes:

1. Nominal cooling capacities are based on the following conditions:

Return air temperature: 80°FDB, 67°FWB

Outdoor temperature: 95°FDB

Equivalent ref. piping length: 25 ft / 7.5 m (Horizontal)

2. Nominal heating capacities are based on the following conditions:

Return air temperature: 70°FDB.

Outdoor temperature: 47°FDB, 43°FWB

Equivalent ref. piping length: 25 ft / 7.5 m (Horizontal)

3. Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.

4. The airflow is set to STANDARD before leaving the factory. You can switch between STANDARD ESP and HIGH ESP with the remote controller.

Refer to the fan curves for actual fan performance.

5. Anechoic chamber conversion value, measured under JISB8616 conditions. During actual operation, these values are normally somewhat higher as a result of installation conditions.

6. Refer to page 10 for Power Input.

REFRIGERANT PIPING WORK

For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.

Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, or water leakage can result.

Use insulation that can withstand temperatures of at least

250°F. Reinforce the insulation on the refrigerant piping according to the installation environment. If the temperature above the ceiling reaches 86°F or the humidity RH80%,. condensation may form on the surface of the insulation.

CAUTION

Follow the points at below.

• Use a pipe cutter and flare suitable for the type of refrigerant.

• Apply ester oil or ether oil to the flare section when using a flare connection.

• Only use the flare nuts included with the unit. Using different flare nuts may cause the refrigerant to leak.

• To prevent dust, moisture or other foreign matter from infiltrating the piping, either pinch the end or cover it with tape.

• Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air. If any refrigerant gas leaks while working on the unit, thoroughly ventilate the room immediately.

• The outdoor unit is charged with refrigerant.

• Be sure to use both a spanner and torque wrench together, as shown in the drawing, when connecting or disconnecting pipes to/from the unit. (Refer to Fig. 6)

Ensure that oil does not to adhere to any portions other

22 FXDQ-M

EDUS39-600-F2_a than a flare part. If oil adheres to resin parts., deterioration can occur.

• Refer to Table 2 if no torque wrench is available.

Using a wrench to tighten flare nuts causes the tightening torque to suddenly grow much tighter after a certain point.

From there, tighten the nut further by the appropriate angle listed in Table 2.

(5) After the work is finished, ensure there is no gas leak.

(6) After checking for gas leaks, be sure to insulate the pipe connections referring to Fig. 8.

• Insulate using the insulation for fitting (3) (4) included with the liquid and gas pipes. Besides, make sure the insulation for fitting (3) (4) on the liquid and gas piping has its seams facing up.

Tighten both edges with clamp (9).

• For the gas piping, wrap the middle sealing pad (6) over the insulation for fitting (4) flare nut part.

Precautions when laying power supply wiring

• Wiring of different thicknesses cannot be connected to the power supply wiring terminal block. (Slack in the power supply wiring may cause abnormal heat.)

• Use sleeve-insulated round crimp-style terminals for connections to the power supply wiring terminal block. When none are available, connect wires of the same diameter to both sides, as shown in the following figure.

Insulation sleeve

Round crimp-style terminal

Connect wires of the same gauge to both sides.

Do not connect wires of the same gauge to one side.

Electric wire

Do not connect wires of different gauges.

Follow the instructions below if the wiring gets very hot due to slack in the power supply wiring.

• For wiring, use the designated power supply wiring and connect firmly, then secure to prevent outside pressure being exerted on the terminal board.

• Use the correct screwdriver for tightening the terminal screws.

If the blade of screwdriver is too small, the head of the screw might be damaged, and the screw will not be properly tightened.

• If the terminal screws are tightened too hard, screws might be damaged.

• Refer to the following below for the tightening torque of the terminal screws.
