START-UP

I. PRELIMINARY CHECKS
1. Check that all internal wiring connections are tight
and that all barriers, covers, and panels are in place.
2. Field electrical power source must agree with unit
nameplate rating.
3. All service valves must be open.
4. Crankcase heater must be tight on compressor crank-
case (if equipped).
II. LEAK TEST
Field piping and fan coil must be leak tested by pressure
method. Use R-410A at approximately 25 psig backed up
with an inert gas to a total pressure not to exceed 245 psig.
NOTE: Leak detectors should be designed to detect HFC
(hydrofluorocarbon) refrigerant.
III. EVACUATE AND DEHYDRATE
Field piping and fan coil must be evacuated and dehydrated
following good refrigeration practices.
IV. START UNIT WITH OPERATING TEST
Turn power on to the unit. Insert batteries in remote control.
Press the and the
5 seconds. The remote control will be cleared and the time
segment will display the Src1=service test mode.
Press the button to transmit the service test signal to
the unit. After the test has completed press the
to leave the test menu.
NOTE: When 30 seconds have elapsed and no buttons have
been pressed, the remote control will automatically exit the
test menu and resume its normal operation.

NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load equipment (refer to NEC Articles 430 and 440), the over-
current protective device for the unit shall be fuse or equipped with a
breaker.
2. Motor RLA values are established in accordance with UL (Underwrit-
ers Laboratories) Standard 465.
V. CONFIGURING TWO INDOOR UNIT REMOTE CONTROLS
If two indoor units are being installed in the same room,
working independently, two remote controls need to be con-
figured for proper operation.
A. Unit Configuration
Turn the unit off by pressing the
and buttons of the remote control for more than
5 seconds. The display will be cleared and the time segments
will display the first configuration item (rAdr=remote
address) and the temperature segments will display the
default value of this configuration item (Ab=control of both
indoor units). Press
to the new value of (a) or (b). Press the
mit the new configuration to the unit. Press the
to leave the configuration menu.
B. Remote Control Configuration
Turn the unit off by pressing the
the and buttons for more than 5 seconds. The dis-
play will be cleared and the time segments will display the
first configuration item (CH=remote address) and the tem-
perature segments will display the default value of this con-
figuration item (Ab=control of both indoor units). Press
and to change the default value to the new value of (a) or
(b). Press the button to transmit the new configuration
to the unit. Press the
menu.
NOTE: When 30 seconds have elapsed and no buttons have
been pressed, the remote control will automatically exit the
test menu and resume its normal operation.
