SELECTING THE MOUNTING POSITION

Decide the mounting position with the customer as follows:

1. INDOOR UNIT

(1) Install the indoor unit level on a strong wall which is not subject to

vibration.

(2) The inlet and outlet ports should not be obstructed : the air should

be able to blow all over the room. (3) Install the unit near an electric outlet or special branch circuit. (4) Do not install the unit where it will be exposed to direct sunlight. (5) Install the unit where connection to the outdoor unit is easy. (6) Install the unit where the drain pipe can be easily installed. (7) Take servicing, etc. into consideration and leave the spaces shown

in (Fig. 2). Also install the unit where the filter can be removed.

2. OUTDOOR UNIT

(1) If possible, do not install the unit where it will be exposed to direct

sunlight. (If necessary, install a blind that does not interfere with

the air flow.) (2) Do not install the unit where a strong wind blows or where it is very

dusty. (3) Do not install the unit where people pass. (4) Take you neighbors into consideration so that they are not disturbed

by air blowing into their windows or by noise. (5) Provide the space shown in Fig. 2 so that the air flow is not blocked.

Also for efficient operation, leave open three of the four directions

front, rear, and both sides.

[Reverse cycle type only]

(6) Since the drain water flows from the outdoor unit during heating

operation, when it is installed at a high place, install the drain pipe

as shown in (Fig. 4) and connect it to a 16 mm (inside diameter)

hose available anywhere. (Fig. 4)

WARNING

Install at a place that can withstand the weight of the indoor and outdoor units and install positively so that the units will not topple or fall.

CAUTION

(1) Do not install where there is the danger of com-

bustible gas leakage. (2) Do not install near heat sources. (3) If children under 10 years old may approach the

AIR PURGE

Close the high pressure side valve of the gauge manifold fully and do not operate it during the following work.

1. Check if the piping connections are secure.

2. Check that the stems of 2-way valve and 3-way valve are closed fully.

3. Connect the gauge manifold service hose to the charging port of the 3-way valve (side with the projection for pushing in the valve core).

4. Open the low pressure side valve of the gauge manifold fully.

5. Operate the vacuum pump and start pump down.

6. Slowly loosen the flare nut of the 3-way valve and check if air enters, then retighten the flare nut. (When the flare nut is loosened the operating sound of the vacuum pump changes and the reading of the compound pressure gauge goes from minus to zero.)

7. Pump down the system for at least 15 minutes, then check if the compound pressure gauge reads -100 kPa (-76 cmHg, -1 bar).

8. At the end of pump down, close the low pressure side gauge of the gauge manifold fully and stop the vacuum pump.

9. Slowly loosen the valve stem of the 3-way valve. When the compound pressure gauge reading reaches 1-2 kg/cm retighten the valve stem and disconnect the service hose from the 3-way valve charging port. (If the stem of the 3-way valve is opened fully before the service hose is disconnected, it may be difficult to disconnect the service hose.)

WARNING

(1) Install the unit where it will not be tilted by more

than 5°.

(2) When installing the outdoor unit where it may ex-

posed to strong wind, fasten it securely.
