Getting Started
⚠ CAUTION
Always use a grounded outlet that meets minimum voltage supply requirements for industrial equipment. Do not use with portable power generators.
⚠ CAUTION
Always open valves slowly for safety, and to check for leaks.
⚠ CAUTION
The G5Twin is equipped with a 550psi (38.6 kg/cm
2
) pressure shut off switch to protect the machine from damage. This does not prevent overfilling of the storage container. (See Page 6)
ACCESSORY EQUIPMENT
Additional tools and equipment are used to connect the G5Twin to the system you are recovering refrigerant from. Verify operational details and safety information from the manufacturers of other equipment before use.
PREPARING FOR OPERATION
Before connecting or operating the G5Twin, verify that your accessory equipment is in good working condition:
•
.
A leaking hose may cause venting of refrigerant, and may introduce atmospheric air or other contaminants into the recovered refrigerant. Examine the gaskets on each hose to ensure they are intact, checking for any damage or wear that may lead to leaks.
•
Examine your external manifold gauges for proper valve operation and calibration of the gauges.
Contact the manifold gauge manufacturer for instructions in this process.
•
Check your refrigerant scale with a known weight to ensure that is operating correctly. A malfunctioning scale may not alert you to the amount of refrigerant in the storage container.
•
Check that the debris screen at the inlet fitting is clean before starting every job. This screen prevents damage to the machine that may get past the inline filter. When pumping dirty/used refrigerant, this screen may quickly clog and slow the process when used without an inline filter.
•
Verify the power source provides adequate voltage at the machine while it is running (within 10% of the rated power). When using an extension cord, follow the sizing guidelines on Page 4.
•
Remove all “Schrader”-type access valve cores from the access fitting. Remove core depressors from the hoses. Hoses going into the tank and hoses connected to the outlet of the G5Twin should be completely open and free from any restrictions (no core depressors, no “quick disconnect” fittings).
•
Use a new inline filter dryer with the machine when pumping dirty refrigerant. Replace the filter dryer after each use. If the filter has exceeded its capacity, this may affect the performance of the machine.
•
To maximize recovery speeds: use the shortest length of 3/8” hoses possible. Even with 1/4” fittings, the larger hose can deliver better performance during vapor recovery. When using a Manifold Gauge
Set, use a manifold with a 3/8” or larger diameter bore to maximize liquid and vapor refrigerant flow.
•
When using 3/8” hoses and manifolds, some slight valve throttling on the Manifold Gauge Set may be helpful in reducing compressor noise in some conditions (such as with very cold refrigerant), though it is not required for proper operation of the machine.
