Do not charge system with a mixture of
R-404A refrigerant and R-452A refrigerant.
In order to be compliant with ATP rules, it is
recommended to check with your local ATP
authorities if any procedures exist to declare
refrigerant type.
Below instructions are to be followed for
following products: Xarios 150 / 200 / 300 /
350 / 500 / 600 / 500MT / 600MT
Depending on the refrigerant to be used for your
mounting, place the appropriate decal as per below
recommendations.
1. On the "safety decal" (fig.1), either place the R-
404A decal or place the R-452A refrigerant
decal on the dedicated location as per beside
drawings.
2. On each evaporator, either place the R-404A
decal or place the R-452A refrigerant decal close
to TXV depending on the refrigerant to be used

COMPRESSOR: PREPARATION
COMPRESSOR INSTALLATION
Refrigeration oil is very hygroscopic ! The compressor is under a nitrogen
pressure • Before the compressor mounting, make sure that
the compressor has an adhesive label fitted, proof that it is charged with Carrier oil type (no oil change to do)
• Never leave a compressor crankcase opened If one of these two points is not respected, compressor oil should be change and the right level of oil should be refilled (see the table ) with Carrier POE 68 oil from a brand new tank.

Cleaning method for gauge hoses
To allow accurate reading and to reduce pollution in the refrigeration circuit, it’s necessary to clean the gauge hoses before commissioning:
Refrigerant bottle is closed
Manifold gauge valves are closed except the refrigerant bottle and the vacuum pump which are opened.
Start the vacuum pump, wait 2 to 3 seconds and close the pump
The connections are cleaned and ready for the commissioning
This operation can’t be done on 3 way service gauges
Warning !
The evacuation has to be done with a vacuum pump (see page 15) and not by purging with the refigerant bottle.

Charging with refrigerant
See attached chart for weight
Add refrigerant to correct level
REFRIGERANT CHARGE
Unit charge must be done monitoring the weight of the
refrigerant bottle :
Install the manifold gauges on “free Schrader” fitting
located inside the condenser on the high pressure
line.
Place refrigerant bottle on scale and connect charging
line from bottle to manifold
Purge charging line for inlet manifold and fittings
using a vacuum pump
Note the weight of refrigerant bottle. Be sure that he
unit is stopped during this operation
Open liquid valve on refrigerant bottle and allow the
liquid refrigerant to flow into the unit until the correct
weight of refrigerant has been added as indicated by
the weight scale.
When refrigerant bottle weight (scale) indicates that
the correct charge has been added, close the
manifold valves.
NOTE : it is possible that all the liquid may, to be pulled

Definition :
The superheat is a T° difference between: The T° indicated on the expansion valve bulb and the evaporating temperature
It is imperative to set correctly the superheat to
Optimise the unit performance
Increase compressor « life time »
Practice :
Connect the low pressure gauge to the evaporator
Place a « thermocouple »at the expansion valve bulb
Start the unit to reduce the box temp to (0°C or -20°C)
Check superheat setting
If this value is not correct, adjust the expansion valve
Tighten the screw to increase the superheat value
Loosen the screw th reduce the superheat value
COMMISSIONING: SUPERHEAT
A correct superheat is:
S/H = Bulb T° - Evaporating T°
(thermometer) (BP manometer)
Example : (thermo.) - 31°C - (mano.) - 35°C - = S/H 4°C

COMMISSIONING: OIL CHARGE
Carrier compressors are delivered with 180ml of oil and pressurized with nitrogen.
Oil charge must be completed (see table), with the oil
delivered with the unit.
Those oil quantities include the 180ml/6,08.Oz of oil
already inside the road compressor.
Example: Xarios 600MT = 680 ml/22,99Oz. The
compressor is provided with 180ml/6,08.Oz
=> add 500ml/16,9.Oz in the circuit.
Adjustment:
Fill the extra oil in the unit using one of the following 2
options:
1 - After vacuum process, using the vacuum pump on LP
side. Oil will be drawn in by differential pressure through
the liquid receiver for oil quantity up to 600ml
2 - Into the oil separator (200 ml /6,76.Oz max).
At commissioning let the unit run 10 min at idle speed to
allow a good lubrication.
