Evaluation of Performance During

Test Run

In order for the test run to be successful the system must be con-
tinuously running for 15-20 minutes. After that period the system's
refrigerant charge must be checked once more.
Procedure
1. Measure the pressure from the gas side service valve.
2. Measure the temperature of the intake and discharge of air
(Figure 50).
3. Verify that the difference in temperature between the intake air
and discharge air is more than 46.4 °F.
4. Refer to Table 18 for the gas side valve's optimum pressure.
5. If the unit passes these evaluations steps, it is ready for use.

Installing Batteries into Remote
Controller
As part of test running, you will need to insert batteries and power on
the remote controller. To insert the batteries follow the steps below. For
information on using the remote controller, refer to its owner's manual.
Procedure
1. The remote controller needs two AAA (1.5V) batteries (non-re-
chargeable) for operation. Remove the battery cover from the back
of the remote controller (Figure 49).
• Push 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 usage as
needed.
