10.4.5. Indoor unit drain piping • Be sure to use the drain hose provided (accessory item.) • Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the drain port at the indoor unit. - Page 54 2. Precautions in high humidity circumstance. This air conditioner has been tested according to the “JIS Standard Conditions with Mist” and have been confirmed that there is no form of any faults. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C), water drops are liable to fall.

Caution As a rule, please collect all existing refrigerants in the system outside the system when the refrigerant leakage occurs by the Caution system.
- Page 62 12. Be sure to leave enough space around the outdoor unit to maintain proper performance and to allow access for routine maintenance. • Allow enough space from any obstacles as shown in Fig. 1.2 below in order to prevent short-circuits from occurring. (If installing more than one outdoor unit, make the necessary space available as outlined in 13.) However, there should be at least 1 meter of free space above the unit.
- Page 63 • If a drain pipe needs to be installed, insert the accessory drain elbow into the mounting hole at the bottom of the outdoor unit, and connect a hose with an inside diameter of 15mm to this drain elbow. (The hose is not supplied.) If using the drain elbow, install the outdoor unit on a base which is at least 5cm high.

3. Notes when connecting the refrigerant pipes. • Use clean copper, pipes with no water or dust on the insides. • Use phosphorus-free, unjointed copper pipes for the refrigerant pipes. • If it is necessary to cut the refrigerant pipes, be sure to use a pipe cutter, and use compressed nitrogen or an air blower to clean out any foreign particles from inside the pipe. - Page 65 • Pump down operation - Operate the pump down according to the following procedures. Procedure Notes 1. Confirm the valve on the liquid side and the gas side is surely open. 2. Press the PUMP DOWN switch on outdoor printed board for 1 second Perform the cooling operation for five minutes or more.

11 Installation and Servicing Air Conditioner Using R410A 11.1. Outline 11.1.1. About R410A refrigerant 1. Converting air conditioners to R410A Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a destructive danger to the ozone layer in the earth’s upper stratosphere (20 to 40 km above the earth), measures have been taken around the world to prevent this destruction. -
Page 85: Tools For Installing/Servicing Refrigerant Piping
d. R410A refrigerating machine oil Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle. -
Page 86: R410A Tools
11.2.2. R410A tools 1. Copper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type)) • This gauge makes it easy to set the clearance for the copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool. - Page 87 5. Charging hose • The pressure resistance of the charging hose has been raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports.
- Page 88 8. Electronic scale for refrigerant charging • Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading.

11.3. Refrigerant piping work 11.3.1. Piping materials It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries. - Page 90 Table 11 R410A flaring dimensions Nominal Outside Wall thickness A (mm) diameter diameter (mm) R410A flaring Conventional flaring tool (mm) tool, clutch type Clutch type Wing-nut type 6.35 0 - 0.5 1.0 - 1.5 1.5 - 2.0 9.52 0 - 0.5 1.0 - 1.5 1.5 - 2.0 12.70...

Page 91: Installation, Transferring, Servicing
b. Copper pipes Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use. - Page 92 11.4.2. Transferring (Using new refrigerant piping) 1. Removing the unit a. Collecting the refrigerant into the outdoor unit by pumping down The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low.
- Page 93 Precaution: Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid without having to turn the cylinder around 6. Remove the charging hose of the manifold gauge from the vacuum pump adaptor, and connect it to the connection port of the electronic scale.
- Page 94 11.4.6. Brazing As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N ) flow.

12 Troubleshooting Guide If test operation does not proceed correctly Carry out test operation after approximately 12 hours have passed since the power was turned on (crankcase heater is energized). If operation is started by using the remote control within 1 minute of turning on the power, the outdoor unit settings will not be made cor- rectly and correct operation will not be possible. - Page 96 (When remote control display shows “power supply”) Clock setting, and no timer setting (When remote control display shows “No power supply”)
