JOWA REP-1L
饮用水紫外线消毒器
JOWA REP-1L sterilises drinking water with one low-pressure UV lamp in a stainless steel chamber. A photocell measures UV intensity and gives an alarm and closes the outlet solenoid valve when it falls below 30 %; a lamp ammeter monitors the lamp. It is fitted after the pH filter, storage tank and hydrophore, as close to the tapping point as possible. The manual covers specification, installation, start-up, chamber cleaning, lamp and quartz jacket replacement, a troubleshooting chart, wiring and parts.
