2.Installation A. Heat pump installation location and attentions *. Heat pump is not allowed to be installed in the place where combustible gas may leaks. *. Heat pump is not allowed to be installed in the place where there is oil or corrosion gas released.
Tips for installation related to the water pipe part: *Install a valve at the highest point of each water circulations for releasing air from water system. * A Y filter is very important in front of circulating water pump of heat pump. * If more heat pumps installed in one water pipe system, the connection of these heat pumps can’t be in series, only can be in parallel or independent.

5.4 Except there is water level error, hot water tank temp sensor error, when there is other temp error, high and low pressure error protection, electric heater will start. Remarks: EVI-HH series, only hot water side has electric heater function, heating side doesn’t have.
Part 3. Maintenance and repairing A. Daily maintenance Heat pump is high automatic equipment, if can check and maintain periodically, the stability and lifetime of heat pump will increase greatly. 1. When using and maintain the heat pump, please note: all security device have been set before leave factory, please don’t adjust anymore.
