Warnings and Safety Information
This machine is for use by trained and certified professionals only.
Always wear gloves and eye protection when using this machine or handling refrigerants.
Read all Material Safety Data Sheets (MSDS) for any compounds that you are likely to encounter.
Failure to do so could lead to injury or death. This equipment is not to be used with any combustible
or flammable materials, doing so could lead to injury or death.
To reduce the risk of fire, extension cords must be at least 12AWG and not longer than 15 ft. This
equipment should be used in areas with mechanical ventilation providing at least four air changes
per hour, or be located at least 18” above the floor. Do not use this equipment near any spilled
or open containers of gasoline or other flammable liquid.
Remove all refrigerant from the system before connecting the vacuum pump. Attempting to
evacuate the system while it is under high pressure may cause damage to the vacuum pump.
To reduce the risk of equipment damage or fire, do not leave the TEZ8 running while unattended.
Disconnect the TEZ8 from the power supply before any maintenance or service of the TEZ8 to
reduce the risk of electrical shock or injury.
Keep out of reach of children at all times.
Machine Usage
Caution:
Always use a grounded 3-prong outlet.
Caution:
Always remove all refrigerant from the system before connecting the vacuum pump.
We recommend using the Appion G5Twin for this purpose. Equipment damage may
occur if the evacuation is started while the AC/R system is under high pressure.
Note:
For the deepest final vacuum, ensure that all fittings and hose connections are properly
and tightly secured before beginning the evacuation process.
Note:
Before beginning the evacuation process, verify that the Debris Monitor/Catch tube (located
in the right-front corner of the TEZ8) is free and clear of any debris or oil.
Standard Setup
1.
2.
3.
Install a fresh T
EZ
OM oil cartridge into the front of the Appion TEZ8 Vacuum Pump before
using (See
Page 5: Changing the Oil
for further details).
Connect the pump to the system according to the AC/R manufacturer’s guidelines.
A.
Install a vacuum-rated ball valve or manifold between the system and the TEZ8 to
allow for isolation of the system at the end of the evacuation process.
If you are using a vacuum gauge, attach it to the access port on the system that is farthest
from the TEZ8.
