Correct installation is required to ensure safe operation. The requirements for Enviro-Tex heat pumps include the following: 1. Appropriate site location and clearances. 2. Wiring to conform to 17 edition wiring regulations. 3. Adequate water flow. This manual provides the information needed to meet these requirements. Review all application and installation procedures completely before continuing the installation. - Page 10 The foundation of the heat pump can be a cement or steel structure. Anti-vibration rubber feet and a flat foundation are generally required. The foundation structure can be flexibly designed according to the working weight of the heat pump. (Please see the technical data in this manual.) Water drainage should be available near the installation location for draining water in an effective way.
