Drain piping

CAUTION
Following the Installation Manual, perform the drain piping work so that water is properly drained. Apply a heat insulation so as not to cause a dew condensation.
Inappropriate piping work may result in water leakage in the room and wet furniture.

• Provide the indoor drain piping with proper heat insulation.
• Provide the area where the pipe connects to the indoor unit with proper heat insulation. Improper heat insulation will cause condensation to form.
• The drain pipe must be sloping downward (at an angle of 1/100 or more), and do not run the pipe up and down (arched shape) or allow it to form traps. Doing so may cause abnormal sounds.
• Restrict the length of the traversing drain pipe to 20 meters or less. For a long pipe, provide support brackets at intervals of 1.5 to 2 meters to prevent flapping.
• Install the collective piping as shown in the following figure.
• Do not provide any air vents. Otherwise, the drain water will spout, causing water to leak.
• Do not allow any force to be applied to the connection area with the drain pipe.
• A hard PVC pipe cannot be connected to the drain pipe connecting port of the indoor unit. Be absolutely sure to use the flexible hose provided for the connections with the drain pipe connecting port.
• Adhesive agents cannot be used for the drain pipe connecting port (hard socket) of the indoor unit. Be absolutely sure to secure the pipe using the hose bands provided. Use of an adhesive agent may damage the drain pipe connecting port or cause water to leak.

They vary depending on the outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit.
**CAUTION**
IMPORTANT 4 POINTS FOR PIPING WORK

1. Reusable mechanical connectors and flared joints are not allowed indoors. When mechanical connectors are reused indoors, sealing parts shall be renewed. When flared joints are reused indoors, the flare part shall be refabricated.
2. Tight connection (between pipes and unit)
3. Evacuate the air in the connecting pipes by using VACUUM PUMP.
4. Check the gas leakage. (Connected points)

Pipe size

Connecting refrigerant piping
Flaring

• Cut the pipe with a pipe cutter. Remove burrs completely. Remaining burrs may cause gas leakage.
• Insert a flare nut into the pipe, and flare the pipe. As the flaring sizes of R32 differ from those of refrigerant R22, the flare tools newly manufactured for R32 are recommended. However, the conventional tools can be used by adjusting projection margin of the copper pipe.

Projection margin in flaring: B (Unit: mm)

Outer dia. of copper pipe| Tool used| Conventional tool used
---|---|---
6.4, 9.5| 0.5 to 1.1| 1.0 to 1.5
12.7, 15.9| 0.5 to 1.1| 1.5 to 2.0

Flaring diameter size: A (Unit: mm)

Outer dia. of copper pipe| A +0
–0.4
---|---
6.4| 9.1
9.5| 13.2
12.7| 16.6
15.9| 19.7

CAUTION

• Do not scratch the inner surface of the ared part when removing burrs.
• Flare processing under the condition of scratches on the inner surface of are processing part will cause refrigerant gas leak.
•  Check that the ared part is not scratched, deformed, stepped, or attened, and that there are no chips adhered or other problems, after are processing.
• Do not apply refrigerating machine oil to the are surface.
• In case of aring with the conventional are tool, pull it out approx. 0.5 mm more than that for R22 to adjust to the specied are size. The copper pipe gauge is useful for adjusting projection margin size.
  • The sealed gas was sealed at the atmospheric pressure so when the are nut is removed, there will no “whooshing” sound: This is normal and is not indicative of trouble.
  •  Use two wrenches to connect the indoor unit pipe.
  • Use the tightening torque levels as listed in the table below.

Tightening torque of are pipe connections.
Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle. Align the centres of the connecting pipes and tighten the are nut as far as possible with your ngers. Then tighten the nut with a spanner and torque wrench as shown in the gure.
CAUTION
Tightening with an excessive torque may crack the nut depending on installation conditions.
