f) After selecting the number of the indoor unit to be forced to stop, press the SET (S007) key for longer than 1
second. The forced thermostat OFF setting is set for the selected indoor unit. TEST/WARNING indicator (red
LED (D052)) lights up.
In order to cancel the forced stop, after selecting the number of the indoor unit, press the SET (S007) key
for longer than 1 second. The forced thermostat OFF setting is canceled for the selected indoor unit. TEST/
WARNING indicator (red LED (D052)) goes off.
g) After completing the tests, remove the setting.
∗ Regardless of the number of indoor units operating, the engine rotation speed depends upon the load at
that time.
16HP - 30HP : 800 - 2,200 min
● Check that there is no error metallic noise from the compressor.
● Check that there is no error metallic noise or tappet noises from the engine.
Check that there is no error vibration in each part of the units.
● Check that there is no error vibration in the refrigerant tubing or capillary tubes. (particularly during low rota-
tional speeds)
● Check that there are no error vibrations due to contact between tubing, fi ttings, panels, etc.
a) For safety, when the outdoor units are stopped, set the total stop setting (Set S001 (STOP-SW) to "STOP") on
all outdoor main boards of the corresponding refrigerant system. (Figure 25)
* When this is set, "    " is displayed on the seven-segment LED display for 3 minutes, and then "   "
is displayed. (Figure 26)
b) When stopping only specifi c outdoor units in the same refrigerant system, set the total stop setting for only the
outdoor units you want to stop. Only outdoor units for which the total stop setting is not set will be in an operable
state. In such a case, all valves of the outdoor units for which the total stop setting was set will open. Operating the
other units while the valves are open will result in refrigerant liquefaction. Close the corresponding closing valves of
the outdoor units for which the total stop setting was set.
