DEMAND
The power is
supplied to the
outdoor unit.
Take due care
during the work to
prevent electric
shock.
(3) • When performing the
low-noise operation
(L.N.O.P.) or demand
(DEMAND) operation
upon request from the
customer, perform the
setting using the
pushbutton switches (BS1
to BS5) on the PC board
(A2P) in the outdoor unit.
• Press each pushbut-
ton switch from the
opening of the
insulation cover.
(Do not remove the
insulation cover.)
The power is supplied to the
•
outdoor unit. Take due care during
the work to prevent electric shock.
Before using the pushbutton
•
switches (BS1 to BS5) for setting,
confi rm that the microcomputer
(SERVICE) monitor is lit.
For the setting method, refer to the
•
[Cautions on service] label attached
on the back of the front panel of the
outdoor unit. (Make sure to write the
contents of setting on the [Cautions
on service] label.)
(4) Confi rm that the stop
valves are open on both
the liquid and gas lines. If
they are closed, open them.
Caution
Do not leave any stop
valve closed.
Otherwise the
compressor will fail.
(5) Press and hold the test
run button (BS4) for
5 seconds or more to start
the check operation.
For the details, refer to the
Check operation procedure
on the [Cautions on
service] label.
When leaving the outdoor unit
•
during the check operation for
unavoidable reasons, ask another
installation worker to watch the
outdoor unit, or close the front panel.
The system operates the check
•
operation for about 15 minutes
(30 minutes maximum), then stops
automatically.
The system can start normal operation
about 5 minutes after the check
operation if the remote controller does
not display any malfunction code.
During the check operation, the
•
status under execution is indicated
on the remote controller.
(6) After the check operation, make sure to close the front panel of
the outdoor unit.
<Cautions on check operation>
If the air conditioner is started within about 12 minutes after
•
the power of the indoor/outdoor unit is turned on, the H2P
indicator lights and the compressor does not run.
Confi rm that the LED status is as shown in the table in (2) in
“
9-1 Power on and check operation
” before starting the air
conditioner.
The air conditioner may require about 10 minutes maximum
•
until it can start the compressor after start of operation.
This period of time is required to homogenize the refrigerant
status, and does not indicate any failure.
The check operation does not provide any means of check-
•
ing the indoor unit individually. For that purpose, perform the
normal operation using the remote controller after fi nishing
the check operation.
The check operation is not available in any other mode such
•
as the recovery mode.
Before running a check on the unit, changing the indoor
•
remote controller settings might cause the error code “UF” to
be displayed and prevent a proper check to be run.
Checks in normal operation
9-2
After fi nishing the check operation, operate the air condi-
•
tioner normally.
(Heating is not available if the outside air temperature is
75 °F or more. Refer to the operation manual supplied
together with the unit.) (Heating is only available for RZQ-P
models.)
Confi rm that the indoor and outdoor units are operating
•
normally.
(If a knocking sound is heard in the liquid compression of
the compressor, stop the air conditioner immediately and
energize the crankcase heater for a suffi cient period of time,
then start the operation again.)
Check to see if cold (or hot) air is coming out of the indoor
•
unit.
Press the fan direction button and fan speed control button
•
on the remote controller to see if the fan is operating nor-
mally.
<Cautions for normal operation check>
Once stopped, the compressor will not start for about
•
5 minutes even if the “
ON/OFF
” button on the remote con-
troller is pressed.
When the system operation is stopped by the remote con-
•
trol, the outdoor unit may continue to operate for a further
3 minutes.
If the system has not undergone the check operation by the
•
test run button since it was fi rst installed, a malfunction code
“U3” is displayed.
In this case, perform the check operation by referring to
“
9-1 Power on and check operation
”.
