Test Run; Precautions - Sanyo SPW-C706VH8 Instrucciones De Instalación

10-13. Test Run

Using the control unit
(1) Change the indoor control unit switch from "ON" → "TEST".
(The outdoor unit will not operate for 3 minutes after the
power is turned ON and after operation is stopped.)
(2) All the indicator lamps blink while the test run is in
progress.
(3) Temperature control is not possible during the test run.
(4) If correct operation is not possible, the trouble will be
indicated by the indicator lamps. Refer to "Table of Self
Diagnostic Functions and Corrections" and correct the
problem.
(5) After the test is completed, change the control unit switch
from "TEST" → "ON". Confirm that the indicator lamps
have stopped blinking. (A function is included which
cancels the test run after a 60-minute timer has elapsed, in
order to prevent continuous test run operation.)

●
This mode places a large load on the devices. Use it only for
performing test runs.
●
A test run is not possible if the power is turned ON with the
switch in the TEST position.
After the power has been turned ON, change the switch
once to ON or OFF, then switch it back to the TEST position.

10-14. Precautions

●
Request that the customer be present when the test run is
performed. At this time, explain the operation manual and
have the customer perform the actual steps.
●
Be sure to pass the manuals and warranty certificate to the
customer.
●
Check that the 220 – 240 V AC wiring is not connected to the
inter-unit control wiring connector terminal.
* If 220 – 240 V AC is accidentally applied, the indoor or
outdoor unit control PCB fuse (0.5 A for both indoor and
outdoor units) will blow in order to protect the PCB. Correct
the wiring connections, then disconnect the 2P connectors
(indoor: blue) (outdoor: blue, serial 1) that are connected
to the PCB, and replace them with 2P connectors (indoor:
brown) (outdoor: brown, serial 2).
If operation is still not possible after changing the brown
connectors, try cutting the varistor (black) (both indoor and
outdoor).
(Be sure to turn the power OFF before performing this
work.) (Fig. 10-10)
