BEFORE USING

SAFETY PRECAUTIONS

Check for any shipping damage. Place a
claim with carrier if damage is discovered.

DO NOT USE A DAMAGED UNIT.

The machine should not be operated or
serviced by any person who has not read
all the contents of this manual. Failure to
read and comply with these instructions or
any one of the limitations noted herein
can result in serious injury and/or property
damage.

These general instructions describe
normal operation and maintenance
situations encountered. The instructions
should not be interpreted to anticipate
every possible contingency.

It is the responsibility of the owner/user to
operate the machine in accordance with
all specifications and laws which may
apply.

The following pages contain rules for safe
operation. Taking precedence over any
specified rule listed herein, however, is
the most important rule of all:

! Recover, Recycle, and Charge only

the refrigerant for which this machine
is configured.

! Wear safety glasses and protective

gloves. Refrigerant has a very low
boiling point and can cause frostbite.

! Follow operation procedures

sequentially to avoid prematurely
disconnecting hoses or opening
valves which may release refrigerant
to the atmosphere.

! Do not expose the machine to

moisture or operate in wet areas.

! Use the machine in locations with

mechanical ventilation that provides at
least four air changes per hour.

! Hoses have shutoff devices within 30

mm of the connection point to the
system being serviced to minimize the
introduction of Non-condensable Gas
(Air) into the machine and the release
of refrigerant when being
disconnected.

"USE COMMON SENSE"

A few minutes spent reading these
instructions can make an operator aware
of dangerous practices to avoid and
precautions to take for his own safety and
the safety of others.

A regular schedule of inspection should
be established and records maintained
with special attention given to Hoses and
Filters.

! Disconnect machine from power

before performing any maintenance or
service.

! Avoid using an extension cord. If

necessary, use a good condition, 3­wire grounded, 2.5 mm
cord of the shortest possible length.

2

extension

! Connect the machine to a properly

protected, grounded receptacle. Do
not over load the circuit.

! Do not allow the machine to remain

unattended in the Charge Mode with
power On. The Internal Cylinder
Heater will be energized creating a
high pressure condition.
