Bell & Gossett A07180C Enhanced Air Separator EASB-JR - Manual (Page 2)

INST ALLATION INSTRUCTIONS
Enhanced Air Separators with Sweat Connections
1. Install the air separator in horizontal piping so that the air
vent is in the top vertical position. The air separator is
bi-directional so that water can flow in either direction
(see Figure 1).
2. Use a torch with a sharp pointed flame.
3. Clean tube ends and air separator connection thoroughly.
4. Use 95-5 (Tin-Antimony) solder and a good grade of flux.
5. When sweating joints, first wrap the air separator with a cool
wet rag, then direct the flame with care to avoid subjecting
the EASB-JR to excessive heat.
6. Refer to Chart A for the maximum operating pressure and
temperature based on the type of solder used.
7. After sweating the joints, check the connections for leakage.
Enhanced Air Separators with NPT Connections
1. Install the air separator in horizontal piping so that the air
vent is in the top vertical position. The use of Teflon tape
sealer or a high quality thread sealant is recommended. The
air separator is bi-directional so that water can flow in either
direction (see Figure 1).
2. Check connections for leaks.
OPERA TING INSTRUCTIONS
T urn the cap on top of the vent counterclockwise one full turn to
allow the EASB-JR to automatically remove the air from the
system. This is the normal operating position.
To shut down the automatic air vent, turn the cap tight. Be sure
to turn the cap back to the open position (one full turn) for
normal operation.
SER VICE INSTRUCTIONS
The Enhanced Air Separator should not r equire servicing. If the
system fluid contains large amounts of contaminants, the
perforated metal strainer may become contaminated with
foreign substances. The Enhanced Air Separator cap unscrews
from the body for easy cleaning of strainer.
CAUTION: The use of T eflon ® impregnated pipe com-
pound and Teflon tape on pipe threads provides lubricity
which can lead to overtightening and breakage. Do not over-
tighten. Failure to follow this instruction can result in moder-
ate personal injury from hot water and/or property damage.
CAUTION: Contaminants and scale fr om the system
can foul the automatic air vent operation mechanism.
Keep vent cap closed tight during the system filling to pre-
vent contaminants from running into valve vent mechanism.
Failure to follow these instructions could result in property
damage and/or moderate personal injury.
W ARNING: Servicing the Enhanced Air Separator with
unit pressurized or at temperatures above 100°F
(37.8°C) can cause personal injury. Make sure pressure is
removed from unit and temperature is below 100°F (37.8°C).
Failure to follow these instructions could result in serious
personal injury or death and property damage.

CAUTION: Heat associated with the use of silver solder
may damage a Air Separator voiding the warranty. Do
not use silver solder. Failure to follow these instructions could
result in proper damage and/or moderate personal injury.
CAUTION: Hot venting can be hazar dous. Avoid con-
tact with venting fluid and only manually vent when
system temperature is below 100°F (38°C). Failure to follow
these instructions could result in property damage and/or
personal injury.
W ARNING: State of California Residents
This pr oduct contains a chemical known by the State
of California to cause cancer. This product contains a chemi-
cal known by the State of California to cause birth defects or
other reproductive harm.
CAUTION: Uncontr olled venting of water can occur
with automatic air vents if foreign material prevents
vents from closing. Unwanted flow should be directed to a
drain. Failure to follow these instructions could result in prop-
erty damage and/or moderate personal injury.
