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 bat-

teries if system won't be used for an extended time.

Test Run

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

1. Check that all drain piping, refrigerant piping, and wiring / cables are properly connected.

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

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

4. Turn on the power to the outdoor unit, and test system operation.

5. As system operating, make notes as needed to troubleshoot any issues that might appear.

Performance Evaluation

Operate the unit in heating and / or cooling, depending on outdoor conditions, for 15 to 20

minutes, then check the system refrigerant charge (feature availability depends on model):

1. Measure the pressure of the gas (vapor) suction service valve. See optimum psig in table

at right.

2. Measure the air temperature from both the inlets and outlets.

3. Verify the difference between the inlet and outlet temperatures is > 14.4°F.

4. The air conditioner is now ready to use.

• If all modes can't be tested all at one time, testing must be performed later when weather

conditions permit.

• If the actual pressure is higher than shown, the system is most likely overcharged, and

charge must be removed. If the actual pressure is lower than shown, the system is most

likely undercharged, and charge must be added.
