Installation 2. Installation/Tubing/Electrical wiring WARNING ● On sensing danger or abnormality, suspend operation immediately and inspect/ solve problems. Caution ■ Installation 1. Ambient temperature around the pump should not exceed 40°C. Observe the allowable maxi- mum ambient humidity of 90%RH. This product is designed for indoor use only. - Page 22 Installation ■ Tubing 1. Tube should be thick enough. The use of a thin and light tube may reduce suction force and an air flow. CAUTION Avoid sharp turns or bends. Otherwise, an tube end may break. 2. The short tubing with the minimum bends is opti- mal to reduce resistance.
- Page 23 Installation ■ Electrical wiring Electrical wiring must be done by a qualified person who has a full knowledge of safety. We are not respon- sible for personal injury or property damage due to nonobservance of this warning. Contact us or your near- est distributor as necessary.
