INSTALLATION FOR QUICK-CONNECT LINES
seal test
Remove the sealing caps from both of the stop valves on the outdoor air conditioner. Use a wrench to slightly unscrew
the valve on the thin lines counter-clockwise and immediately re-close it. The lines are now under coolant pressure and you
can check the connections for tightness using soapy water. If the soapy water bubbles up, the seal is not tight. If this is the
case, use the open-ended wrenches to retighten the screwed connections. Then insulate the connections with the supplied
insulation to prevent condensation.
After the tightness check is complete, open both valves on the outdoor air conditioner using the wrench, unscrew them to
the stop, and re-seal with the valve caps. The air conditioner cannot function unless the valves are completely opened up.
WiRing
· A power connection exclusively dedicated to the air conditioner must be provided.
· Make sure that the voltage complies with the rated voltage for the air conditioner.
Voltage Fuse
50 Hz 220-240 V~ 16A C - automatic cut-out ≤ 1.5 mm
caution
· Only make the connections if the requirements are met.
· By law, short-circuit insulation must be provided at the installation location to prevent electric shock.
· Do not cut electrical wires to size to extend them.
· The voltage must range between 90% and 110% of the rated voltage.
· The electrical outlet for the air conditioner must be grounded. Therefore, a grounding receptacle must be used so that
the air conditioner can be insulated effectively.
