MODELS:PED-2,2.5EJA WIRING DIAGRAM
NOTES
1. Since the outdoor side electric wiring may change be sure
to check the outdoor unit electric wiring for servicing.
2. Symbols used in circuit diagram above are, :Terminal block,
:connector.
3. Emergency operation
If a trouble occurs with either the remote controller or
the indoor microcomputer and no other trouble exists,emer-
gency operation for cooling can be performed by changing
the setting of dip switch (SW3<I.B>) on the indoor controller
board (emergency dry operation is not possible).
<Check items>
(1) Make sure that no other trouble exists with the outdoor unit.
Trouble with the outdoor unit prevents emergency operation.
(If any trouble exists with the outdoor unit,the trouble
location will be displayed on the remote controller and
the trouble position will be shown on the outdoor contro-
ller board LED.See electric circuit diagram of the outdoor
unit for details.)
(2) Make sure that there is no trouble with the indoor fan.
Emergency operation will be a continuous run with the power
ON/OFF(ON/OFFwith the remote controller is not possible).
<Emergency operation procedure>
(1) Set the dip switch(SW3<I.B>)on the indoor controller board
to 1 - 2 on and 3 off for cooling.
(2) Turn on the outdoor unit side circuit breaker.
(3) During emergency operation indoor fan runs at High speed.
(4) Thermostat will not function.Cold air blows out for defro-
sting during heating thus do not operate de frosting for
a long time.
(5) Emergency cooling should be limited to 10 hours maximum(the
indoor unit heat exchanger may freeze).
