3).spaces
1) Leave enough space above and around unit for operation and maintenance. For cleaning the
copper pipes or exchanging pipes, there should be enough space reserved( for single compressor
unit, it should be at least 3.5m, for dual compressor unit, it should be 5m), and the other end of the
unit should have at least 2.0m space, use the hole on door or other holes with appropriate position;
there should have the space of 0.7m in front of the unit (the side faces to the electric cabinet ) for
operation; the space in front and back of the unit should not less than 0.6m .
2) Do not install the unit at the place exposed to sunlight or other heat sources.
3) Near the power supply where it is convenient for wiring.
4) The floor is solid enough and the location should not easily bring about resonance or noise.
5) Put the unit indoors which should be well-ventilated with low humidity and little dust.

2. Water Pipeline System installation
1) Water quality control
When industrial water is used as chilled water, little furring may occur; however, well water or river
water, used as chilled water, may cause much sediment, such as furring, sand, and so on. Therefore,
well water or river water must be filtered and softened in softening water equipment before flowing
into chilled water system. If sand and clay settle in the evaporator, circulation of chilled water may be
blocked, and thus leading to freezing accidents; if hardness of chilled water is too high, furring may
occur easily, and the devices may be corroded. Therefore, the quality of chilled water should be
