1. General Inf ormation
Thank you for pur ch as in g the ENVIRO Refrig er an t
Recovery Mach in e!
ENV IRO combines an innovative refrige rant gas compressio n syste m with a rugg ed, mou lde d case that i s desig ned
to offer m ax im um pr ot ec tion fr om dama ge during transit
and normal hand li ng.
With normal use and with care as prescribed in this Manual,
you r ENVIRO wi ll give you years of trouble-free operation.
Safety First!
When found on the machine, this inte rnational symbol is i nt en ded to a le rt t he u se r to the presence of important operating, safety and maintenance (servicing) instructions in this Manual. As used in the Manual, it is intended to
draw y ou r at te ntion to critical ite ms .

The ENVIRO is a Recov ery Mach ine for a bro ad range of
refrigerants. Recovering refrigerants into a separate storage c yl in de r i nv ol ve s a process of g as compr es si on ,
resulting in high pressures within the mach in e, t he c onnecting hoses and the st orage c ylinder. High-pressure
sys tems mus t always be treated with care and respect to

Product Saf et y:
The ENVIRO has been designed to meet the requirements
of t he S ta nd ar d fo r Re fr ig er an t Re co very M ac hines, A RI
and certificati on .
If an ap proved cyli nder wit h overfill is no t available always
use an a pp ro ve d sc al e to monit or the cylinders capacit y.
Additionally, a pp roved refrigerant hoses must be used
which have shut-off d ev ic es w it hi n 30 0mm of t he e nd s to
reduce the like li ho od of refrigerant le ak ag e t o the atmosphere when chang in g cy li nd ers or setups.
Responsib il it y:
Onl y a qualified technician who has been prop erl y traine d
in the ca re an d use of s uc h e quipment and in the recovery process itself mu st o nl y op er ate the ENVIRO.
The op er ating in structions are p art of the prod uc t an d
must be st ored i n cl os e pr ox imity to t he E NV IRO wh er e
they should be read il y ac ce ssible to qualifi ed p er so nnel

Be sure t he power is o ff before e xa mi ni ng o r
repairing the recovery unit. R isk of s er io us in jury and death!
Use onl y authorized ref illable refrige rant tanks.
The Unit requ ires the use of recover y tan ks wi th
a minimu m wor king pre ssure of 40 bar (580psi ).
Do n ot overfill t he recovery tank. Tank is full a t
80% capac it y. T he re should b e enough sp ac e
for liquid expansion.
Overfilling of the tank may cause a violent explosion.
A Charging scale is required to prevent overfilling.
It is compu lso ry t o we ar s afe ty g oggles, and protective gl ov es whi le working wi th refri ge ra nt s to

Risk of serious i nj ur y!
Be sure t ha t a ny room w he re work is bei ng co nducted is thoro ug hl y ventilated.
When using an extension cord, the cord should be
a minimum of 1.5 mm (15 awg) and no longer than

occur.
Avoid exposing the equipmment to the sun or rain.
USE CAUTION WHEN OPERATION OUTDOORS.
Be certain that the power cord, the overfill cylinder
safety co rd and th e unit itself are no t pl aced in
water or other pote nt ia ll y dangerous locat io ns .
While the ENVIRO is very safe to oper at e, u si ng

5.
The unit has an Internal High Press ure Shut-Off Sw itc h.
If the pressure ins ide the system is abo ve 38.5 bar, compressor will automatica ll y shut off the power. To restart
the compressor, plea se lower t he internal p ressure and
hit the High Pres su re b utton, then tur n.
When High Pressur e Pr ot ec tion is initiated , pl ea se fi nd

replace the con ne ct ing hose.
c.
The tempera tu re of the ref ri ge ra nt tank is to o hi gh,
pressures is too high — give it some time to cool down
and the pressur e wi ll c ome back to norma l.
6.

7.
In order to gain maxim um re covery spe ed , a hose w it h
inner d ia me ter b ig ge r than 4m m is re commended a nd
the hose should b e sh or ter than 1.5m.
8.
While recover in g la rge amounts of li qu id , us e the

any r es id ua l refri ge ra nt and pu rged wi th dry ni tr og en.
11.
Connection hose with check valve is recommend ed , i t
can prevent ref ri ge rant loss.
