9. The plumbing should be insulated to reduce heat losses, and water treated with a suitable inhibited antifreeze. Note: We recommend installing shut-off valves on the inlet and outlet water connections for ease of serviceability. Page | 6 Cool Energy inverTech Manual v6.6 2020 ©... -
Page 7: Materials Needed For Installation
Note: For detailed specifications of the units please refer to name plate on the units. Correct installation is required to ensure safe operation. The requirements for Cool Energy heat pumps include the following: 1. Appropriate site location and clearances. 2. Wiring to conform to 18 edition wiring regulations. - Page 8 Allow for proper clearances around the unit. Location should allow easy access for maintenance. For any further guidance on heat pump installations for planning purposes, please consult the latest version of the MCS guidelines or your local authority.

Page 25: Weather Compensation
Weather Compensation Your Cool Energy inverTech heat pump is equipped with intelligent weather compensation features. This means your heat pump will adapt itself automatically based on the ambient temperature outside and the system demand. So for example if the temperature outside is warmer, it will lower the flow temperature to your heating system and if its colder it will increase it automatically. - Page 26 Water Temperature Setpoint: Heating Y4 (User heating set point) Y1 (User cooling set point) Cooing Hot water Y4 (User hot water set point) Settings according to weather compensation graphs: Hot Water: Heating: Page | 26 Cool Energy inverTech Manual v6.6 2020 ©...
