Function

The hydronic separator is a device which makes the primary and

secondary circuits connected to it independent, and can be

used on hot or chilled water systems.

The separator is supplied with an air-vent and check valve

assembly to permit automatic discharge of the air in the circuits,

and a drain valve for removing any impurities deposited in the

bottom of the unit.

SAFETY INSTRUCTION

This safety alert symbol will be used in this manual to draw attention to safety related

instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT!

YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY

RESULT IN A SAFETY HAZARD.

CAUTION: All work must be performed by qualified personnel trained in the

proper application, installation, and maintenance of systems in accordance

with all applicable codes and ordinances.

CAUTION: If the hydronic separator is not installed, commissioned and

maintained properly, according to the instructions contained in this

manual, it may not operate correctly and may endanger the user.

CAUTION: Make sure that all the connecting pipework is water tight.

CAUTION: When making the water connections, make sure that the

hydronic separator connecting pipework is not mechanically over-

stressed. Over time this could cause breakages, with consequent water

losses which, in turn, could cause harm to property and/or people.

CAUTION: Water temperatures higher than 100°F (38°C) can be

dangerous. During the installation, commissioning and maintenance of the

hydronic separator, take the necessary precautions to ensure that such

temperatures do not endanger people.

Leave this manual for the user.

Hydronic characteristics The hydronic separator should be sized according to the maximum flow rate value foreseen at the inlet. The selected value must be either that of the primary circuit or of the secondary, whichever is the greatest. UNION Size 1” 1 1/4” 1 1/2” 2” gpm 11 18 26 31 m3/h 2.5 4 6 8.

Procedure for installation and insulation assembly on union models 1. Remove the protective strip from the adhesive surface. Re-close the insulation shells. 2. If the hydraulic separator is used with chilled water spread a thin layer of sealant on the edge of the insulation and wait until the solvent evaporates (10 minutes approx) and the close it again. Procedure for installation and insulation assembly (only for 2” to 4” sizes) A B 1. Remove the two black head covers at the ends. 2.
