Special Operating Notes; Storage - JAVAC XTR-ULTRA JAV-1063 Instrucciones De Seguridad Y Manual De Funcionamiento

4.4.1 The PUSH PULL method is used to move a large amount of liquid refrigerant from the system
being serviced to the recovery cylinder without passing it through the compressor. This method is
only useful when more than 7 Kg of liquid is known to be in the system and it can be easily isolated.
DO NOT ATTEMPT the PUSH PULL process unless you are sure of the situation.
4.4.2 Connect the refrigerant hoses as shown below. Addition of a SIGHT GLASS in line between the
system being serviced and the recovery cylinder can be an important aid to determine when all the
liquid has been transferred and only vapour remains.
4.4.3 This process uses the PULL from the exhausted recovery cylinder and the Discharge PUSH
from the recovery unit to move the liquid refrigerant. Rates in excess of 5 Kg per minute can be
achieved by this procedure.
4.4.4 The SCALE is required in this process to ensure that the cylinder is not over-filled.

4.5 SPECIAL OPERATING NOTES

4.5.1 If during operation the high discharge pressure switch trips, take appropriate action to reduce
the discharge pressure before resetting the switch.

4.6 STORAGE

4.6.1 When the recovery process has been completed, carefully coil the power cord, the refrigerant
hoses and ensuring that no dirt or foreign material is left in the ends or on the connectors.
4.6.2 Place the recovery unit in the service vehicle in its upright position and store the hoses and
cords nearby. Provide reasonable care to place the unit where it will not be subjected to accidental
damage due to shifting items during transit or to heavier objects being placed on its top.
4.6.3 The unit can be stored safely in temperatures of 0°C-50°C and humidity levels up to
95% RH. When stored in conditions that are severe, the unit may need to stabilize in the range
10°C-40°C before it will offer optimum operating performance. For best results, store the unit in an
environmentally controlled area when not in use.
4.6.4 Always purge and vent the machine prior to storage, close valve A & C and leave C in the
Recover Position.
