SETUP AND OPERATION:

3.1

GETTING STARTED:

3.1.1 CAUTION: Only personnel who have been properly trained in the use and
operation of Refrigeration Systems, Refrigerants and Service Equipment should
operate this equipment. Failure to follow proper safety precautions could result in
personal injury or death.
3.1.2 CAUTION: Review the full contents of this Manual before attempting to use
the EVO-OS in actual service.
3.1.3 Identify the refrigerant to be recovered and prepare the EVO-OS for use by installing
an approved filter, hoses and optional shutoff cable or scale per the diagram below.
Refer to Section 4.0 of this Manual for approved accessories.
3.1.4 Connect the AC Power cord to a circuit that is protected by a 4 amp breaker. Use an
extension cord only when absolutely necessary to perform the service; be sure it is the
minimum length required, that it contains a safety ground wire and that it contains
wires sized 16 AWG (1.291 mm) or larger.
3.1.5 Make sure the EVO-OS is set in a stable position and that it is reasonably level;
observe all safety precautions previously noted. Ensure that the fan inlet and discharge
areas on both sides of the machine are clear from obstructions.
3.1.6 Check all connections to ensure they are tight before starting the Recovery Operation.
3.1.7 EVO-OS is a liquid tolerant recovery machine. It is important to remember to
START the machine before opening the INLET valve. Should the compressor start to
'Knock', close the INLET valve immediately and while it is still running, slowly open
the valve back again.
3.1.8 Use a Refrigerant Scale to ensure that the cylinder is not filled to more than 80%
of its capacity by weight. When operating in the NORMAL RECOVERY mode
without the cylinder shutoff it is possible to overfill the cylinder. If you are not sure
check the cylinder weight before transporting. Refer to Section 8.0 of this Manual.
OVERFILLED CYLINDERS CAN RUPTURE EXPLOSIVELY!

NORMAL RECOVERY OPERATION

3.2.1 Connect all cables and hoses as described in Section 3.1 above and as shown in the

interfere with the operation.
