LRMEQ+LRLEQ3+4BY1
Air-cooled refrigeration condensing unit
4P500362-1A – 2018.09
NOTICE
If the power of some units is turned off, the charging
procedure cannot be finished properly.
NOTICE
Before starting charging procedures, check if the 7‑LEDs
display is as normal (see "7.2.4To access mode 1 or 2"on
page 29). If a malfunction code is present, see
"11.3 Solving problems based on error codes" on
page34.
NOTICE
In case of maintenance and the system (outdoor unit+field
piping+indoor units) does not contain any refrigerant any
more (e.g., after refrigerant reclaim operation), the unit has
to be charged with its original amount of refrigerant (refer
to the nameplate on the unit) and the determined additional
refrigerant amount.
6.7.3 To determine the additional refrigerant
amount
INFORMATION
For final charge adjustment in a test laboratory, contact
your dealer.
INFORMATION
If only showcase units are used, parameter B=0. If only
blower coils will be used, parameter A=0.
INFORMATION
If R≤0, there is no need to charge/recover additional
refrigerant.
Formula for LRMEQ3+4
R=[(X

×Ø9.5)×0.06+(X
2
×Ø6.4)×0.02]+A+B
R Additional refrigerant to be charged [in kg and rounded off
to 1 decimal place]
X

Total length [m] of liquid piping size at Øa
A+B Parameters A (for showcases) and B (for blower coils). See
tables below.
Parameter A
If the total capacity
(a)
of showcases is... Then A is...
<5.0kW 1.1kg
5.0≤x<8.4kW 2.3kg
(a) Capacity at evaporating temperature of –10°C
Parameter B
If the total capacity
(a)
of blower coils is... Then B is...
<5.0kW 0.6kg
5.0≤x<8.4kW 1.2kg
(a) Capacity at temperature difference (=evaporating
temperature – room temperature) of 10°C
Formula for LRLEQ3+4
R=[(X

×Ø9.5)×0.06+(X
2
×Ø6.4)×0.02]+A+B–2.4
R Additional refrigerant to be charged [in kg and rounded off

Total length [m] of liquid piping size at Øa
A Parameter A (in case showcases are used)=1.4kg
B Parameter B (in case blower coils are used)=0.6kg
Metric piping. When using metric piping, replace the weight factors
in the formula by the ones from the following table:
Inch piping Metric piping
Piping Weight factor Piping Weight factor
Ø6.4mm 0.02 Ø6mm 0.018
Ø9.5mm 0.06 Ø10mm 0.066
6.7.4 To charge refrigerant
To speed up the refrigerant charging process, it is recommended to
first pre-charge a portion of refrigerant through the liquid line before
proceeding with the charging via the refrigerant charging port. It can
be skipped, but charging will take longer then.
Pre-charging refrigerant
Pre-charging can be done without compressor operation, by
connecting the refrigerant bottle to the service port of the liquid stop
valve.
1 Connect as shown. Make sure that all outdoor unit stop valves,
as well as valve A are closed.

2 Open valves B and C.
3 Pre‑charge refrigerant until the determined additional refrigerant
amount is reached or pre‑charging is not possible anymore, and
then close valves B and C.
4 Do one of the following:
If Then
The determined additional
refrigerant amount is reached
Disconnect the manifold from
the liquid line.
Continue with the "Checking
the sight glass" instructions.
Too much refrigerant is
charged
Recover refrigerant.
Disconnect the manifold from
the liquid line.
Continue with the "Checking
the sight glass" instructions.
The determined additional
refrigerant amount is not
reached yet
Continue with the "Charging
refrigerant (with the
compressor running)"
instructions.
Checking the sight glass
If the determined additional refrigerant amount is reached by the
"Pre-charging refrigerant" instructions, continue as follows:
5 Open all outdoor unit stop valves.
6 Take all the precautions mentioned in "7 Configuration" on
page28 and "8Commissioning"on page31 into account.
7 Turn on the power of the outdoor unit, but leave the operation
switch turned off (see "6.8.6To connect the electrical wiring on
the outdoor unit"on page26).
