Test Run - Sanyo SAP-CMRV3656EH Technical & Service Manual

Regulations on wire size differ from locality to locality. For field
wiring requirements, please refer to your local electrical codes.
Make sure that the installation fully complies with all local and
national regulations.
(1) Remove access panel "C" and the terminal cover. (Fig. 32)
(2) Connect the inter-unit wiring and power line according to
the drawing on the panel side.
(3) Be sure to size each wire allowing approx. 10 cm longer
than the required length for wiring. Store excess wiring
inside the cabinet.
(4) When connections are completed, check that all
connections are correct as shown in the wiring
system diagram on panel side.
(5) Be sure to ground the unit according to your local codes.

6. Test Run

Performing a test run
G
Refer to the test run procedures in the indoor unit
installation manual.
G Perform the test run separately for each connected
indoor unit. If 2 units are operated simultaneously, it is
not possible to correctly check for errors in tubing and
wiring.
G If the room temperature is 15°C or below, it may not
be possible to check for tubing errors with cooling
operation. If this occurs, perform heating operation for
each unit individually, and check that warm air is dis-
charged from each unit. If there is cold air mixed in
with the warm air, check the tubing connections
again.
Checking tubing and wiring
Perform the test run and check that operation is normal.
If there is an error in tubing or wiring, the refrigerant may
flow to indoor unit B when indoor unit A is operated (for
example).
CAUTION
G
Stop operation immediately if there is an error in tubing
or wiring. Turn the power (leakage breaker/fuse link)
OFF, and check whether the inter-unit cables are con-
nected incorrectly, or whether the narrow tubes A and B
are connected in reverse. Correct the connections.
G
If there is an error in tubing, pump-down must be
performed. Be sure to perform pump-down. After
making corrections, again purge the air from the
tubes.
