Finishing the Job

After the Triple Leak and Evacuation (and refrigerant trim charge, if any) procedures have been performed, follow the steps below to open

the refrigerant lines.

1. Verify that the auxiliary service port is removed (if used in the Evacuation procedure) and the original Schrader core was re-installed on

the gas (vapor) suction service port.

2. The service ports are a back-seated type with a right hand thread. Remove the service valve caps on both the gas (vapor) suction and the

liquid service ports.

3. Using an appropriately sized Allen wrench, fully open the valves on both the gas (vapor) suction and the liquid service ports by turning the

valve stem counterclockwise.

4. Turn until the valve stem is out, stops, and the valve is completely backseated.

5. Securely replace service port caps on both the gas (vapor) suction and the liquid using an adjustable wrench.

Installing Batteries into the Handheld Remote Controller

For information on using the handheld remote controller, refer to its owner's manual.

1. The remote controller needs two AAA (1.5V) batteries for operation. Remove the battery cover

from the back of the remote controller by pushing downward on the tab at the top of the battery

cover, and then lift up to remove.

2. Insert the two new batteries.

• Align batteries by the (+) and (-) sides.

• The interior battery compartment of the remote controller will have clear markings for the (+)

and (-) placement.

3. Verify that the batteries have clicked into the compartment and are firmly engaged with the

contacts on either side of them.

4. Reattach the back cover of the remote controller.

5. Proceed with powering on the remote controller and use as needed. Remove the batteries if

system won't be used for an extended time.

Test Run

After all installation procedures are complete, the system is ready for a test run. Follow the guidelines below.

1. Verify that the power supply is ±10% of the rated voltage.

2. Check that all drain piping, refrigerant piping, and wiring / cables are properly connected. Check if the drain piping and refrigerant piping

are fully and correctly insulated.

3. Check that both the gas (vapor) suction and liquid refrigerant piping service valves are fully open.

4. Install the batteries into the handheld remote controller (see above).
