1. General Information

Thank you for purchasing the ENVIRO-DUO Refrigerant

Recovery Machine!

ENVIRO-DUO combines an innovative refrigerant gas

compression system with a rugged, moulded case that is

designed to offer maximum protection from damage during

transit and normal handling.

With normal use and with care as prescribed in this Manual,

your ENVIRO-DUO will give you years of trouble-free

operation.

Safety First!

When found on the machine, this international symbol

is intended to alert the user to the presence of important

operating, safety and maintenance (servicing) instructions

in this Manual. As used in the Manual, it is draw

your attention to critical items.

It is important to read this entire Manual and be familiar with

its contents before using the machine!

intended to

The ENVIRO-DUO is a Recovery Machine for a broad range

of refrigerants. Recovering refrigerants into a separate

storage cylinder involves a process of gas compression,

resulting in high pressures within the machine, the connecting

hoses and the storage cylinder. High-pressure systems must

always be treated with care and respect to prevent careless

accidents.

Instruction Manual ENVIRO-DUO English

The ENVIRO-DUO has been designed to meet the

requirements of the Standard for Refrigerant Recovery

Machines, ARI and certification.

If an approved cylinder with overfill is not available always

use an approved scale to monitor the cylinders capacity.

Additionally, approved refrigerant hoses must be used which

have shut-off devices within 300 mm of the ends to reduce

the likelihood of refrigerant leakage to the atmosphere when

changing cylinders or setups.

Product Safety:

A qualified technician who has been properly trained in the

care and use of such equipment and in the recovery process

itself must only operate the ENVIRO-DUO.

Responsibility:

The operating instructions are part of the product and

must be stored in close proximity to the ENVIRO-DUO

where they should be readily accessible to qualified

personnel at all times.

The qualified personnel must have carefully read and

understood the operating instructions prior to operating

the device.

The manufacturer shall not be liable for any damage

whatsoever arising through improper use, failure to comply

with these operating instructions, assignment of inadequately

qualified personnel, or unauthorised modification of the

ENVIRO-DUO.

The General Terms and Conditions as set out in the sales

documentation shall apply.

Subject to technical modifications.

DANGER!

The activities described in these operating instructions

should only be carried out by skilled personnel in

possession of the qualifications outlined below.

Keep unqualified personnel away from hazardous areas.

Instruction Manual ENVIRO-DUO English

Skilled personnel are workers who, through their specialist

training and operational knowledge of the recovery machine,

are capable of carrying out the described work and

independently identifying potential hazards.

Skilled personnel

ONLY QUALIFIED SERVICE PERSONNEL SHOULD

OPERATE THIS UNIT. MOST STATES AND

COUNTRIES, MAY REQUIRE THE USER TO BE

LICENSED. PLEASE CHECK WITH YOUR LOCAL

GOVERNMENT AGENCY.

2.2 Special Hazards

Before starting the Equipment assure that it is

well grounded.

Risk of serious injury and death!

While using the electrical wire, the wire must be

well connected and grounded.

Risk of serious injury and death!

Only a qualified electrician should perform wire

connection according to the technical standard

and circuit diagram.

Risk of serious injury and death!

When using an extension cord, the cord should

be a minimum of 1.5 mm (15 awg) and no longer

than 7.5 m. Otherwise Voltage may drop and damage

the compressor! The cable must be completely

unrolled.

English Instruction Manual ENVIRO-DUO

Be sure the power is off before examining or

repairing the recovery unit. Risk of serious

injury and death!

Use only authorized refillable refrigerant tanks.

The Unit requires the use of recovery tanks with

a minimum working pressure of 40 bar (580psi).

Do not overfill the recovery tank. Tank is full at

80% capacity. There should be enough space for

liquid expansion.

Overfilling of the tank may cause a violent

explosion.

A charging scale is required to prevent overfilling.

It is compulsory to wear safety goggles, and protective

gloves while working with refrigerants to protect

skin and eyes from refrigerant gas and liquid. Avoid

any contact with caustic gas or liquid.

Risk of serious injury!

Be sure that any room where work is being

conducted is thoroughly ventilated.

Instruction Manual ENVIRO-DUO English

Input pressure of the unit should not exceed 26

bar (377 psi).

Only keep unit in a horizontal position, otherwise

unexpected vibrations, noise or abrasions may

occur.

Avoid exposing the equipmment to the sun or rain.

USE CAUTION WHEN OPERATION OUTDOORS.

Be certain that the power cord, the cylinder overfill

safety cord and the unit itself are not placed in

water or other potentially dangerous locations.

While the ENVIRO-DUO is very safe to operate,

using in environments such as hard rain or sand

and dust storms must be avoided.

FLAMMABLE ENVIRONMENTS ARE

DANGEROUS

when any machine is used because motors and

switches can generate sparks. This equipment should

be used in locations with mechanical ventilation

providing at least four air changes per hour, or the

equipment should be located at least 50 cm above

the floor.

DO NOT USE THIS EQUIPMENT IN THE

VICINITY OF SPILLED OR OPEN CONTAINERS

OF GASOLINE OR ANY OTHER FLAMMABLE

Do not block the ventilation opening of the unit.

If the overload protector pops, reposition it after

5 minutes.
