KEEP THIS MANUAL IN A HANDY PLACE FOR FUTURE REFERENCE. IMPROPER INSTALLATION OR ATTACHMENT OF EQUIPMENT OR ACCESSORIES COULD RESULT IN ELECTRIC SHOCKS, SHORT-CIRCUITS, LEAKS, FIRE OR OTHER DAMAGE TO THE EQUIPMENT. BE SURE TO ONLY USE ACCESSORIES MADE BY THE SUPPLIER WHICH ARE SPECIFICALLY DESIGNED FOR USE WITH THE EQUIPMENT AND HAVE INSTALLATION DONE BY A PROFESSIONAL ALL ACTIVITIES DESCRIBED IN THIS MANUAL SHALL BE CARRIED OUT BY A LICENSED TECHNICIAN. BE SURE TO WEAR ADEQUATE PERSONAL PROTECTION SUCH AS GLOVES AND SAFETY GLASSES WHEN PERFORMING INSTALLATION, MAINTENANCE OR SERVICE TO THE UNIT. IF UNSURE OF INSTALLATION PROCEDURES OR USE, CONTACT YOUR DEALER FOR GUIDANCE ■ Operation range (*) The unit can not operate in cold weather conditions below -15℃. If it is necessary to operate, an external auxiliary heat source must be added as a backup heater. the backup heater also serves as a backup in case of malfunctioning of the unit and for freeze ptrotection of the outside water piping during winter time. These models have an antifreeze function that allows the use of heat pumps to keep the water system free from freezing under all conditions. If there is an accident or intentional power outage, it is recommended to use ethylene glycol. 2. ACCESSORIES 2.1 Accessories supplied with the unit 1.1 General information ■ These units are used for both heating and cooling applications. They can be combined with fan coil units, floor heating applications (connect the mixed station), low temperature high efficiency radiators (field supply). ■ The host unit controller is standard supplied with the unit to control the system. ■ A wired remote controller can also be used to control the system (Optional). 1.

Only some precautions and tips and tricks about the design of the water circuit are given in a separate chapter of this manual. Once the selection is done and the water system is designed, this manual describes the procedures for handing, installing and connecting the unit, This manual has been prepared to ensure adequate maintenance of the unit, and it will provide help if problems occur. This unit is designed to cool/heat water and must be used in applications compatible with its performance characteristics, i.e. residential or commercial applications combined with a fan coil unit, low temperature radiators and underfloor heating. It should never be used for underfloor cooling, as doing so may damage the plate heat exchanger. 1
