5. Test Operation (4/5/10/12 HP Models)
Follow the following procedure to conduct the initial test operation after installation.
5.1 Check Work Prior to Turning Power Supply ON
5.2 Turn Power ON
• Is the power supply appropriate?
• Have you finished a ductwork to drain?
• Have you detach transport fitting?
• Is the wiring performed as specified?
• Are the designated wires used?
• Is the grounding work completed?
Use a 500 V Megger tester to measure the insulation.
Do not use a Megger tester for low voltage circuits.
• Are the setscrews of wiring not loose?
• Is the electrical component box covered with an insulation
cover completely?
• Is pipe size proper? (The design pressure of this product is
4.0 MPa.)
• Are pipe insulation materials installed securely?
Liquid and gas pipes need to be insulated.
(Otherwise causes water leak.)
• Are respective stop valves on liquid and gas line securely
open?
• Is refrigerant charged up to the specified amount?
If insufficient, charge the refrigerant from the service port of
stop valve on the liquid side while the outdoor unit is not
operating after turning power ON.
• Has the amount of refrigerant charge been recorded on
“Record Chart of Additional Refrigerant Charge Amount”?
Check on refrigerant piping /
insulation material
Check on amount of refrigerant
charge
Check the below items.
•
Power wiring
•
Control transmission wiring
between units
•
Earth wire
• Be sure to turn the power ON 6 hours before starting
operation to protect compressors.
• Close outside panels of the outdoor unit.
Turn outdoor unit power ON.
Turn indoor unit power ON.
Carry out field setting on
outdoor PCB
