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.

DESCRIPTION

The Rolairtrol Air Separator is an ASME vessel designed with tangential open-

ings to create a low velocity vortex where air is separated and removed from the

circulating water. The Rolairtrol is designed and constructed per ASME Section

VIII, Division I. This product is intended for hot and chilled water systems.

OPERATIONAL LIMITS

Maximum Operating Temperature: 350°F

Maximum Operating Pressure: 125 PSIG

INSTALLATION INSTRUCTIONS

1. Refer to Figures 1 and 2 for the proper installation of the Rolairtrol.

2. Rolairtrol sizes through an “R-8” or “RL-8” can be supported in the piping sys-

tem as long as pipe hangers are attached to the tangential nozzles as close

to the Rolairtrol shell as possible. Sizes larger than an “R-8” or “RL-8” will

need to have additional supports, such as a cradle under the Rolairtrol acting

on a diameter as close to the Rolairtrol outside diameter as possible or facto

installed support brackets.INSTALLATION INSTRUCTIONS

Note: Welding to the pressure vessel boundary will void the ASME stamp.

3. Model “R” Rolairtrol Air Separators have strainers which must be removed

and cleaned after 24 hours of operation, 30 days of operation and as

required to maintain proper system air separation. Before installing the model

“R” Rolairtrol refer to Table 2 for minimum distances t

o be maintained

between the blowdown connection or end of the pipe plug and the floor or

other equipment for strainer removal.

4. A manual blowdown valve (MBV-1) can be added to the blowdown connec-

tion. The function of the MBV-1 is to facilitate the purging of sediment from

the vessel.

5. A manual blowdown valve (MBV-1) can be added to the 3" through 12" tanks

of the R models, by removing the 3" pipe plu

g and replacing with the proper

sized reducer.

personal injury and property hazards and to ensure safe use and

proper care of this product.

NOT FOR USE IN DOMESTIC (POTABLE) WATER SYSTEMS

DANGER: Rolairtrol Air Separator is for use in closed loop systems

only. Domestic, potable or fresh water can cause serious corrosion in a

tank. This can result in leakage and property damage. Do not use for

domestic, potable or fresh water. Failure to follow this instruction will result

in serious personal injury and property damage.

CAUTION: Hot uninsulated surfaces can cause burns to the skin. Do

not touch hot surfaces. Failure to follow these instructions could

result in moderate personal injury.

CAUTION: Use unit lifting lugs only to lift unit as shipped from

factory. Unit must be empty and disconnected from pipe, and other

restraints. Use proper rigging procedures. Failure to follow these instruc-

tions could result in injury or property damage.

WARNING: Wet weight of Rolairtrols can exceed strength of sup-

ports. Make sure the provisions are made to support the wet weight

and not just the dry weight (see Table 1). Failure to follow these instruc-

tions could result in serious personal injury or death and property damage.

WARNING: This product must be installed by a qualified professional.

Failure to follow the instruction in accompanying manual may cause

a leakage or explosion which may result in serious injury or death and

property damage.

WARNING: The use of improper mating flanges, connectors, gaskets

or bolting can cause flange or connector failure resulting in the loss

of hot or cold system fluid. Use only companion cast iron ANSI flanges or

connectors with appropriate gaskets and properly tightened bolts. Failure

to follow this instruction can result in serious personal injury and/or prop-

erty damage.
