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.
