FEATURES
CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT
maximum 10 m (PUHZ-SW40/SW50)
The refrigerant circuit with LEV (Linear Expansion Valve) and power receiver always control the optimal refrigerant level
regardless of the length (10 m maximum and 5 m minimum) of piping. The additional refrigerant charging work during instal-
lation often causes problems. It is completely eliminated by chargeless system. This unique system improves the quality
and reliability of the work done. It also helps to speed up the installation time.
