G1SINGLE OPERATION MANUAL

How to Make an External Cooling Accessory:

Making an ECA uses the same tools as you would use when installing an AC/R

system. You will need 50 feet of 1/2” (OD) copper tubing, and two (2) 3/8” FL Service

Valves. Connect the service valves to each end of the copper tubing with solder

using industry practices. Then, coil the tubing around a pipe or round object of

at least 8” inches in diameter, and maintaining about 1/8” spacing between each

coil. Leave about 2 feet of the copper tubing straight, and bend it upwards, so that

both extend above the “coiled area,” as in Diagram 9. Prior to using the ECA, verify

pressure and vacuum tightness using the same methods as on an AC/R system.

Alternative: A 50 foot, 1/2in (OD) copper Immersion Wort Chiller with two (2) 3/8in

FL service valves fitted to the ends of the copper tubing can also be used in place of

making your own.

How to Use an External Cooling Accessory:

Using a 5-gallon bucket (or equivalent container), submerge

50% of the ECA in water before adding ice. Continue to add ice

until the ECA is submerged below the ice by at least 3 inches.

This will help keep the ice water cooled as the heated vapor

travels through the ECA.

Important: If the ice melts, replenish the ice as needed to maintain

maximum cooling throughout the recovery process.

Connect the ECA and hoses equipped with ball valves as shown

in Diagram 10. Submerge the ECA in a bucket of ice water (as

described above). Close the ball valve on Hose “C”, and open

the ball valves on Hose “A” and Hose “B”, as shown in Diagram

10. Proceed with the Standard Recovery Procedure as described

on Page 9, starting from Step 2, and continuing through Step 9

(substitute the Recovery Cylinder Liquid Port in Step 2).

WARNING: Aer recovery is complete, the ECA and Hoses A, B and

C will contain high pressure refrigerant.

To recover the residual refrigerant from the ECA:

1. Close the Recovery Cylinder liquid valve, and the ball valve at

the end of Hose “A”.

2. Disconnect the hoses from the G1Single input/output.

3. Connect the hoses as shown in Diagram 11.

4. Open the Recovery Cylinder vapor valve, and all 3 ball valves.

5. Repeat Steps 6-9 from Page 9 to finish the recovery.
