7. Operation
1.
Do not mix diffe rent refrigeran ts together i n one tank,
otherwise they cannot be separated o r used.
2.
The switch should be at“Position 0”before operation. All
the valves m ust be closed, the input and output fittings
should be covered with protective caps when the unit is
not in operation. Air humidity is harmful to the recovery
result and will shorten the life span of t he unit.
3.
A filter drier should always be used and should be replaced
frequently. Each type of refrigerant must have its own
filter. For the sake of ensuring the proper operationof the
unit, please use the filter specified by our company.
High quality filter drier will bring h igh quality services.
4.
Special caution is needed when recovering from a burnt
system. In th is case two dry filters are r equired.
5.
The unit has an Internal High Pressure Shut-Off Switch.
If the pressure inside the system is above 38.5 bar, th e
compressor will automatically sh ut off the power.
To restart the compressor, please lower the internal pressure,
then push on the start button to restart the compressor.
When High Pressure Protection is initiated, please find out
the cause and deal with it before restar ting the unit.
Cause of High Pressure Protection an d Trouble Shooting:
a.
The input value o f the refrigerant tank is c losed — open
the valve to solve the problem.
12
English Ins truction Manual ENVIRO-DUO
b.
The connecting hose between the reco very unit and
refrigerant tank is stuck — close all the valves and replace
the connecting hose.
c.
The temperature of the refrigerant t ank is too high,
therefore, pressure s is too high — give it some time to
cool down and the pressure will come back t o normal.
d.
The unit has an I nternal Lo w Pressure Shut-Off Swit ch
and delay circuit. If the pressure inside the system is below
-2.5 ~ -6.8 psi for 20 seconds, the unit will auto-matically
shut off and the Green Alarm Light wi ll switch on.
When the unit completes recovery and purge oper-ation,
there is no pressure in the intake port. Therefore the unit
can only run for 20 seconds after restar t.
When the input pressure is above 0.8 bar (11 psi), the
unit will run continuously.
e.
This unit can be used together with a overfill level sensor.
Please connect the recovery uni t and the tank with the
80% O.F.P. Cable (Item 1 in the PARTS DIAGRAM).
If the liquid refrigerant reaches 80% capacity of the tank,
the recovery unit will auto matically shut off and the Red
Alarm Light wil l s witch on (80% O.F.P. ALARM). Before
restart please replace tank.
f.
If the refr igerant tank has no f loat level sensor, pl ease
take the 80% O.F.P Cable off. Otherwise the recov ery
unit can not start. In this case, an electric scale is required
to monitor the recovered refrigera nt amount.
13
Instructi on Manual ENVIRO-DUO English
g.
In order to gain maxim um recovery s peed, a hose with
inner diameter bigger than 4 mm and shorter than 1.5 m
is recommended.
h.
While recovering large amounts of li quid, use the
Push/Pull Mode.
I.
After recove ring, make sure there is no r efrigerant left
in the unit. Read the Pu rge Operation careful ly. Liquid
refrigerant remaining in the unit may be expanded and
damage the components.
j.
If the unit is to be stored or not used for any length of time,
we recommend that it be comple tely evacuated of any
residual refrigerant and purged wi th dry nitrogen.
k.
A connection hose with check valve is recommended, it
can prevent refrigerant loss.
l.
The intake port is equipped with filte r screen;
please wash it frequently to keep it cle an.
m.
If it is difficult to start the unit, please turn the Sw itch
two rounds to balance the inte rnal pressure and make
it easier to start the unit.

12. Maintenance
1.
Your ENVIRO-DUO will provide many seasons of reliable
service if it is properly maintained. The actual maintenance
requirements are minimal but impor tant.
2.
Keep the unit cle an by wiping it down with a damp cloth
to remove dirt, oils, etc. prior to stor age for the day.
Standard household detergent or isopropyl alcohol may
be used if the unit is particularly dirt y; in all cases,
exercisecare to prevent liquids from entering the unit.
Gasoline and other solvents are to be avoided as they
can damage the ENVIRO-DUO's plastic enclosure and
they are hazardous.
3.
Clean inlet particle filter regularly. Discard internal filter
screen if it is heavily contami nated and replac e with a
new screen. Replace screen as per sketch for efficiency.
4.
Ensure that the Inlet and Discharge ports are protected
and kept clean by replacing the plastic caps after every
use. For best results, keep a FILTER permanently
connected to the INLET port and ch ange it regularly.
5.
Change HOSES periodically as they develop leaks and
a build-up of contamina nts over time. Change hoses at
least once per season.
6.
When performance declines it is likely that the compressor
seals require replacing. This is normal with use and may
occur after a year or two or more often, depending upon
the conditions th at are prevalent during there covery
operations. Co ntact your Wholesaler for assis tance in
selecting the proper maintenance k it.
