2. SAFETY PRECAUTIONS
Safety instructions
1. This evacuation and charging machine designed for use only by trained HVACR professionals, and
can be damaged or dangerous if operated incorrectly.
2. For your safety and correct operation, please read the operation manual carefully before use.
3. Never connect vcharging machine to a pressurized system, and always verify system is at atmospheric
pressure or below before connecting hoses to an HVACR system.
4. Protective gloves and goggles should be worn during operation in case refrigerant gas or liquid
comes in contact with skin or eyes.
5. Do not smoke while operating evacuation or charging equipment.
6. Do not use machine near flammable gases, open flames, or other ignition source.
7. Please do not use equipment in direct sun or in rain, cover if needed, leaving adequate room for
ventilation.
8. Always make sure the equipment has good ventilation.
Precautions:
1. The smart refrigerant charging machine is for use with air conditioning and refrigeration systems
only.
2. The red high-pressure hose is connected to the high pressure (liquid) valve on NC-R systems and
blue low pressure hose to the low-pressure (suction) valve.
3. Before operation, verify the type of refrigerant used to insure compatibility.
