Test Run
After the triple leak / pressure and evacuation procedures are com-
plete, perform a test run.
Before the Test Run
1. Check that all condensate tubing, refrigerant piping and power
wiring, and communication / connection (power) cables are prop-
erly connected.
2. Make sure that the gas and liquid service valves are fully open.

If the pressure is >142 psig, the system is most likely overcharged, and refrigerant must be removed. If the pressure is <113 psig, the system is most
likely undercharged and refrigerant must be added.

Installing the Remote Controller Batteries
As part of the test run, the batteries need to be inserted into the remote
controller, and the remote controller will need to be powered on to
operate the indoor units (depending on the indoor units included in the
system). To insert the batteries, follow the steps below. For information
on using the remote controller, refer to its owner’s manual.
1. The remote controller needs two (2) AAA (1.5V) batteries for oper-
ation.
Do not use rechargeable batteries. 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.
4. Reattach the back cover of the remote controller.
5. Proceed with powering on the remote controller and usage as needed.
Test Run Procedure
1. Operate the system in cooling mode for 15 to 20 minutes.
2. Evaluate performance as the system runs, verifying the outdoor unit, and all indoor units and branch distribution units (Multi F MAX sys-
tems only) are working properly. Make notes as needed to address any issues that might be found.
• Check the system refrigerant charge:
• Measure the pressure from the gas side service valve.
• Measure the indoor unit inlet and outlet air temperatures. Verify the difference between the intake temperature and the discharge is
