Improved Serviceability
• All main components like compressors, valves and
refrigerant components are easy to access to simplify
servicing. When the unit is supplied with an hydraulic
module, the service valves and strainer can be
accessed with ease for service.
• Water connections are extended up to the edge of the
unit, for easy connection with system water piping.
• Optional pump package is designed for easy
maintenance and service on site.
• Pressure transducers and temperature sensors
are supplied for easy identifi cation of potential
troubleshooting and eventually, replacement, without
the need of refrigerant handling.
• Dead front panel and IP20 protection allow for safe
servicing.
