Note 1. How to connect refrigerant pipes.

Factory supplied optional refrigerant piping contains refrigerant at the above atmospheric pressure. As long as connec-
tion takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor
units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 20m, an additional charge of refrigerant is needed.

Note 2. The following main parts are contained in the optional refrigerant piping kit.

Heat insulating cover, vinyl tapes, nipples, sleeve, flange (for wall hole).

2. REMOTE CONTROLLER EXTENSION CABLE

When installing the remote controller at a distance from the air conditioner, use the designated extension cable with connec-
tor.

3. TIMER

When using a program timer, a program timer adapter (PAC-825AD) is also needed.

3-1 Program timer specifications

3-2 Feature of program timer

(1) Daily timer function

Daily timer can be set in 30 minute units up to 24 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.

(2) Setback operation. (PAC-SK65PT)

Set back operation is useful for reducing running costs
e.g. : At a hotel with a 24-hour system

8:00~23:00 Cooling operation with set temperature at 26°C
23:00~8:00 Setback operation with 2 degrees of setback

As shown in the chart on the right, the set temperature rises 2
degrees automatically during the setback operation. When the set-
back operation ends, normal operation will begin.

(3) Weekly timer function

Daily timer function can apply to each day of the week.
