LRMEQ+LRLEQ3+4BY1
Air-cooled refrigeration condensing unit
4P545024-1 – 2018.09
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
2
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.

NOTICE
The operation output P1/P2 of the outdoor unit must be
connected to all solenoid valves that are installed upstream
of the expansion valves at the indoor unit. This connection
is required because the outdoor unit must be able to
control the solenoid valves during startup (to prevent liquid
refrigerant from entering the compressor) and oil return
operation.
NOTICE
Remote operation switch. The unit is factory-equipped
with an operation switch with which you can turn unit
operation ON/OFF. If you want to remotely turn outdoor
unit operation ON/OFF, a remote operation switch is
required. Use a voltage-free contact for microcurrent
(≤1 mA, 12 V DC). Connect to X2M/C+D, and set to
"Remote ".
NOTICE
Low-noise switch. If you want to remotely turn ON/OFF
low-noise operation (see setting [2‑18]), you must install a
low-noise switch. Use a voltage-free contact for
microcurrent (≤1mA, 12VDC). Connect to X2M/A+B.
NOTICE
Output signals. The outdoor unit is provided with a
terminal (X3M) that can output 4 different signals. The
signal is 220~240VAC. The maximum load for all signals
is 0.5 A. The unit outputs a signal in the following
situations:
▪ C/C1: caution signal – connection recommended –
when an error occurs that does not stop unit operation.
▪ C/W1: warning signal – connection recommended –
when an error occurs that causes unit operation to
stop.
▪ R/P2: run signal – connection optional – when the
compressor is running.
▪ P1/P2: operation signal – connection mandatory –
when the indoor unit solenoid valve is being controlled.
