OPERATION & PERFORMANCE Performance characteristics of the unit The air-cooled heat pump modular unit is composed of one or more modules. Each module has its own independent electric control unit, and the electric control units of modules conduct information exchange through communication network. The air-cooled heat pump modular unit is characteristics of compact structure and easy transportation and lifting, and in the meanwhile, it also saves facilities, including cooling tower, cooling pump, and so on, for the user, and reduces installation cost.
Never inspect or service the unit by yourself. CONTENTS PAGE Ask a qualified service person to perform this work.
