GENERAL SAFETY
Use information
• In order to prolong the usage of the recovery unit, please read the operating manual carefully before
using , which can help you to fully understand the safety, specification as well as operating procedure
of the recovery unit.
• Please check the product received is same as you ordered and also the accessories operating manual
are attached. Please check the product if there is any damage during transportation . Contact with
local distributor if the above problem is found.
• Please read the operating manual carefully and use the unit according to the product operating
procedures .
Safety indication
AWarning
Indicates procedures that must be strictly observed to prevent hazards to persons .
ANotice
Indicates procedures must be strictly observed to prevent damage or destruction of the unit.
Matters needing attention
AWarning
Only a qualified technician can operate this recovery unit.
Before starting the equipment, make sure that it is well grounded.
While using electrical wire, the wire must be well connected and grounded.
Only a qualified electrician can do the wire connection according to the technical standard
and circuit diagram.
Be sure the power is off before examining or repairing the recovery unit.
If the original power supply cord is damaged, choose carefully for the replacing one, or you
may directly buy from us.
When the unit breaks down, be sure the power is off before you do any operation.

GENERAL SAFETY
Please take power supply and the capacity of your ammeter and electrical wire.
Only authorized refillable refrigerant tanks can be used. It requires the use of recovery tanks with
a minimum working pressure of 45 bar(652.6 psi) . Do not overfill the recovery tank, maximum at
80% capacity to make sure that there is enough space for liquid expansion. Overfilling of the tank
may cause a violent explosion.
Always wear safety goggles and protective gloves while working with refrigerants to protect
your skin and eye from hurting by refrigerant gases or liquid .
Do not use this equipment near flammable liquid or gasoline.
An electric scale is needed to prevent overfilling.
Be sure that the place where you are working is thoroughly ventilated.
ANotice
Be sure the unit is working under the right power supply .
When using anextension cord it should be minimum 2.0mm
2 AWG and no
longer than 2.5 m,
otherwise it may cause the voltage drop and damage the compressor .
The input pressure of the unit should not exceed 26bar(377.1 psi).
The unit need to be laid in horizontally, otherwise it will lead to unexpected vibration, noise or
even abrasion.
Do not expose the equipment to sun or rain.
The ventilation opening of the unit must not be blocked.
If the overload protector pops, reposition it after 5 minutes .
If this equipment is equipped with oil separator deviceonly during vapor recovery process it will
purification and recycling of the refrigerants.
When the recovery vapor over 8 kg it need to release the oil of oil separator device.
(While release oil the internal system must be without pressure)

OPERATION MANUAL
1. Do not mix different refrigerants together in one tank, or they could not be separated or used.
2. Before recovering the
refrigerant , the tank should achieve the vacuum level: - 75cmHg(-29.6psi),
which is for purging non
-condensable gases. Each tank was full of nitrogen when it was manufactured
in the factory, thus the nitrogen should be evacuated before the first use.
3. The
switch should be at "0" Position before operation .All the valves must be closed , the input and
output fittings should be covered with protective caps when the unit is not in operation. The air moisture
is
harmful to the recovery result and will shorten the life span of the unit.
4. A filter
drier should always be used and should be replaced frequently. And each type of refrigerant
must have its own filter. For the sake of ensuring the normal operation of the unit, please use the filter
spec ified by our company . High quality f ilter drier will bring high quality services.
5. Special-caution is needed when recovering from burnt system , and two dry filter is needed .
6. The
unit has an Internal High Pressure Shut-Off switch. If the pressure inside the system is above
rated shut-off pressure (see specification) , compressor will automatically shut off and the high pressure
alarm light will turn on. To restart the compressor, please lower the internal pressure (Output gauge
ind icates lower than 30 bar/435 .1 PSI) , after the high pressure alarm light turn off, hit the Reset
button , then turn on the power to restart the compressor.
When high pressure protection is initiated, please find out the cause and deal with it before restarting
the unit.
Cause of High Pressure Protection and Trouble Shooting :
CD The input valve of the refrigerant tank is closed--open the valve will help solve the problem.
® The connecting hose between the recovery unit and refrigerant tank is stuck--close all the valves
and
replace the connecting hose.
® The temperature of the refrigerant tank is too high, pressure is too high--give it some time to cool
down and the pressure will come back to normal.
7. This unit can be used together with a float level sensor . Please connect the recovery unit and the
tank with the 80% O.F.P. Cable. If the liquid refrigerant reaches 80% capacity of the tank the
recovery unit will automatically shut off and the Red Alarm Light turns on. Before restart please
change a new tank.
8.
Please press " 0" button when start or stop running the machine.
The " 0" light is on when compressor works .

'lR
OPERATION MANUAL
9. If the refrigerant tank has no float level sensor , please take the 80% O.F.P Cable off. Otherwise
the recovery unit can not started . In this case, an electric scale is required to mon itor the recovered
refrigerant amount.
10. In order to gain maximum recover speed , a hose with inner diameter bigger than 4mm is
recommended and the hose should better be shorterthan1.5m.
11. While recover ing large amounts of liquid, use the Push/Pull Mode.
12. After recover ing , make sure there is no refrigerant left in the unit. Read the Purge Operation
carefully. Liquid refrigerant remained in the unit may be expanded and destroy the components.
13. If the unit is to be stored or not used for any length of time, we recommend that it be comp lete ly
evacuated of any residual refrigerant and purged with dry nitrogen .
14. Connection hose with check valve is recommended , it can prevent refrigerant lose.
15. The intake port is equipped with filter screen, please wash it frequently to keep it clean .
16. The Low Pressure Gauge shows the pressure of the intake port of the compressor and the High
Pressure Gauge shows the pressure of the outlet port of the recovery unit.
17. After using , please ture the knob to " 0" position .
