Test Run - Toshiba MMW-UP0271LQ-E Installation Manual

Test run

 Before test run
• Before turning on the circuit breaker, carry out the
following procedure.
1) By using insulation tester (500 VMΩ), check that
resistance of 1 MΩ or more exists between the
terminal block L to N and the earth (grounding).
If resistance of less than 1 MΩ is detected, do
not run the unit.
2) Check the valve of the outdoor unit that is fully
open.
• To protect the compressor at start-up, turn on the
power supply 12 hours or more before operation.
• Before starting the test run, follow the Installation
Manual included with the outdoor unit to set the
address.
• The water supply to the water piping system (above
10°C) should be completed and the pump should be
wired prior to the test run.
When water is not supplied to hot water module, and
when the water does not circulate, the entire system
will stop with an error detected (check code: A01).
 Perform test run
Use the wired remote controller to operate the unit as
usual.
For procedures of this operation, refer to the Owner's
Manual.
A forced test run can be executed in the following
procedure even if the operation stops by thermostat-
OFF. In order to prevent a serial operation, the forced
test run is released after 60 minutes have passed and
returns to the usual operation.
WARNING
Do not use the forced test run for modes other than test
run, as this will put excessive loads on the device.

. Outdoor unit board settings
*1 Do not operate the air conditioner (run the compressor) before the address to the hot water module is fixed.
Doing so will cause the heat exchanger in the hot water module to freeze, rupture, and leak water.
*2 Set DIP switch 4 of SW09 or SW103 on the P.C. board of the header outdoor unit to "ON" (factory default is
"OFF").
The VRF system will be stopped to avoid water freezing when the power supply is disconnected.
NOTE
Before you run the compressor, always confirm that the hot water module is operable (power on, address fixed,
communication wiring complete).
Failure to do this will cause the heat exchanger in the hot water module to freeze, rupture, and leak water.
