(1) ALL ILLUSTRATIONS AND SPECIFICATIONS CONTAINED HEREIN ARE BASED ON THE LATEST INFORMATION AVAILABLE AT
THE TIME OF PUBLICATION APPROVAL. ROBUR RESERVES THE RIGHT TO MAKE CHANGES AT ANY TIME WITHOUT NOTICE, IN
MATERIALS, SPECIFICATIONS, AND MODELS OR TO DISCONTINUE MODELS.
(2) UNITS ARE FACTORY-WIRED FOR 230 VOLT OPERATION.
(3) MAY VARY BY ±10% AS A FUNCTION OF BOTH POWER SUPPLY AND ELECTRICAL MOTOR INPUT TOLERANCE.
(4) THE UNIT HAS 2 WATER CIRCUITS. THE VALUE IS REFERRED TO A SOLUTION OF QUALITY TAP WATER AND 10% BY VOLUME
OF INHIBITED PERMANENT ANTIFREEZE. HIGHER ANTIFREEZE CONCENTRATIONS MAY BE REQUIRED IN CERTAIN
APPLICATIONS. MONO-ETHYLENE GLYCOL MAY CAUSE CORROSION IN GALVANIZED METAL PIPES.
