Test Running
Test Running
Split Type
1.Check that all copper piping and wiring has been proper- ly connected.
2.Check that the gas and liquid side service valves are fully open.
1) Prepare remote controller
Remove the battery cover by pulling it according to the arrow direction.
Insert new batteries making sure that the (+) and
Reattach the cover by pushing it back into position.
NOTE:
•Use 2 AAA(1.5volt) batteries. Do not use rechargeable batteries.
•Remove the batteries from the remote controller if the sys- tem is not going to be used for a long time.
2)Precautions in test run
■The initial power supply must provide at least 90% of the rated voltage.
Otherwise, the air conditioner should not be operated.
■First operate the unit in cooling, even if you are test- ing the unit in the winter/heating season.
Operating the unit in heating first during the test run can cause compressor trouble.
■Carry out the test run more than 5 minutes without failure. (Test run will be cancelled 18 minutes later automatically)
■The test run is started by pressing timer cancel button five times continuously.
■To cancel the test run, press any button.
3)Settlement of outdoor unit
Bolt
Tubing connection
4) Evaluation of the performance
Operate unit for 15~20 minutes, then check the system refrigerant charge:
1.Measure the pressure of the gas side service valve.
2.Measure the temperature of the intake and discharge of air.
3.Ensure the difference between the intake temperature and the discharge is more than 8°C(14.4°F) (Cooling) or reversely (Heating).

■Anchor the outdoor unit with a bolt and nut(ø10mm/0.4inch) tightly and horizontally on a con- crete or rigid mount.
■When installing on the wall, roof or rooftop, anchor the mounting base securely with a nail or wire assuming the influence of wind and earthquake.
■If the vibration from the unit is being transferred to the indoor unit via the connection of the condensation hose and/or copper tubing, secure the outdoor unit with
