Hydrovar Pump Controller Installation & Operation Manual

Technical Data
5.1 General Technical Data
Ambient temperature: 0° C ... +40° C, 32º F... +104º F
At higher temperatures reduce the output current as shown below or
upsize to the next largest HYDROVAR.
The enclosure rating of the HYDROVAR is IP55 however, please note
the following:
• Protect the HYDROVAR from direct sunlight!
• Protect the HYDROVAR from direct rainfall
• Outdoor installation without protection from sun will void warranty!
Storage temperature: -25° C ... +55° C, -10º F ... +130º F
Humidity: RH maximum 50% at 104º F, unlimited
RH maximum 90% at 70º F, maximum 30 days per year
75% average per year (class F)
Condensation is not allowed and will void warranty!
During long periods of inactivity or shutdown, the HYDROVAR should
remain connected to the power supply but turned off to prevent
inadvertant pump run. This will maintain power to the internal heater and
reduce internal condensation.
Air pollution: The air may contain dry dust as found in workshops where there is
excessive dust due to machines. Excessive amounts of dust, acids,
corrosive gases, salts etc. are not permitted
Altitude: Maximum 1000 m, 3280 feet above sea level.
At sites over 1000 m above sea level, the maximum output power should
be de-rated by 1% for every additional 100 m. For installations higher than
2000 m above sea level, please contact your local distributor.
Class of protection: IP 55, NEMA 4 (Indoor use only)
Certifications: CE, UL, C-Tick, cUL
