Checklist After Installation Work - Panasonic S-22MU2E5A Einbauanleitung

9. PRECAUTIONS ON TEST RUN
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.
Check that the 220 – 240 V AC power is not connected to
●
the inter-unit control wiring connector terminal.
* If 220 – 240 V AC is accidentally applied, the indoor unit
control PCB fuse will blow in order to protect the PCB.
Correct the wiring connections. Then disconnect the 2P
connectors (OC) that are connected to the indoor unit PCB,
and replace them with 2P connectors (EMG).
If operation is still not possible after changing the brown
connectors, cut off the jumper on the indoor unit PCB.
(Be sure to turn the power OFF before performing this
work.)

10. CHECKLIST AFTER INSTALLATION WORK

Work List No.
Are the indoor units installed following the
1
Installation content of the section "2. SELECTING
THE INSTALLATION SITE"?
Is the earth leakage circuit breaker
2 (all-pole switching function provided)
installed?
Is there any wrong installation of optional
3
parts or wrong wiring?
4 Was the ground wire work performed?
Are there any wrong power supply wiring,
Tubing &
5 wrong connection wire, wrong signal wire
Wiring
or loose screw?
Is the thickness of wire in accordance with
6
rule?
Is the power-supply voltage range equal
7
to the nameplate of the unit?
Was the check of the airtight test, flared
8 tube fitting and gas leakage on the
welded portion performed?
Has the adhesive been applied to the
9 drain connecting portion (resin portion) of
the indoor unit?
Drain
10 Is there water leakage?
Check
Indoor unit drain pipe has a downward
11 gradient (1/100 or more) by rule. Is the
drain water flowing smoothly?
Was the heat insulation work at a suitable
Heat location including the flared tube fitting
12
Insulation (refrigerant tube & drain pipe) performed
properly?
Was the short-circuit connector connected
Optional
13 or the fan tap changed when installing the
Parts
air-blocking material?
14 Did the abnormal sound occur?
Test Run
Did the cool and warm airflow discharge
15
from the indoor unit?

□
Check Possibility of Failure & Checkpoint
□
There is a possibility of light injure or loss of
property.
□
□
□
Power failure or short circuit may cause electric
shock or fire. Check installation work and ground
□
wire work.
□
□
If the gas leakage occurs, the unit quality not only
□
becomes inferior but affects environment. Repair it
as quickly as possible.
□
The resin portion cracks after a few months and it
may cause water drain.
□
Since there is a possibility of water drain, repair the
□
drain pipe if the drain failure or water drain occurs.
The quality of unit not only becomes inferior but
□
there is a possibility of the water drain. So, perform
the heat insulation work properly.
The discharge temperature decreases in cooling
□
mode according to the reduction of air volume
and there is a possibility of dew drops. Be sure to
change settings.
□
Check if there is a fan contact or distortion of the
indoor unit.
Check if the unit does not operate or there is a
□
wrong tubing or wiring connection with another
system.
