MAINTENANCE
A regular inspection schedule should be adopted and carried out
by competent personnel to examine the pressure vessel for corrosion
and its cause, extent and possible arrest, to determine minimum metal
thicknesses, maximum metal temperatures, calculation of reduction in al-
lowable working pressure and to conduct hydrostatic tests. Also, defects
such as cracks, laminations and distortion of shell, heads or connections
should be noted and repaired if possible, after consultation with and ac-
ceptance by a commissioned authorized inspector who shall be involved
at all stages of any repairs or alterations of the ASME vessel.
In addition, the operation of the air vent, flush cock and drain valves,
and switchable on/off magnet (if installed) should be checked for proper
operation.
CAUTION: MAINTENANCE SHOULD ONLY BE UNDERTAKEN BY
PROPERLY TRAINED AND QUALIFIED PERSONNEL. NEVER OPEN
A VESSEL UNTIL THE SYSTEM PRESSURE IS OFF AND THE VES-
SEL HAS BEEN ISOLATED AND DRAINED. FAILURE TO FOLLOW
THESE INSTRUCTIONS MAY RESULT IN SERIOUS INJURY OR
DEATH.
The Taco automatic air vent located in the top of the air separator is
designed to prevent system fluid or debris from fouling the venting mech-
anism. Periodically the flushing cock on the side of the separator should
be opened by qualified personnel in order to clean any system debris
which may have accumulated at the air/system fluid interface beneath
the vent. CAUTION: MAINTENANCE SHOULD ONLY BE UNDERTAK-
EN BY PROPERLY TRAINED AND QUALIFIED PERSONNEL. CARE
SHOULD BE UNDERTAKEN WHEN OPENING THE FLUSHING COCK
AS SYSTEM FLUIDS MAY BE UNDER HIGH TEMPERATURE AND
OR PRESSURE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY
RESULT IN SERIOUS INJURY OR DEATH. This procedure should only
be performed by properly trained personnel.

LIMITED WARRANTY STATEMENT
A Taco Family Company
Systems where Air/Dirt or Dirt separators are installed should be period-
ically blow down by properly trained personnel to remove sand, dirt or
other system debris. The frequency of this cleaning is dependent upon
the nature of the system fluid. Initially the system is blowdown after
the first 12 hours of operation. Dependent upon the amount of debris
removed during the blowdowns process, subsequent blowdown should
be scheduled for a minimum of three minutes.
The blowdown process should be undertaken by trained personnel
only. CAUTION: MAINTENANCE SHOULD ONLY BE UNDERTAKEN
BY PROPERLY TRAINED AND QUALIFIED PERSONNEL. CARE
SHOULD BE UNDERTAKEN DURING SYSTEM BLOWDOWN AS
SYSTEM FLUIDS MAY BE UNDER HIGH TEMPERATURE AND PRES-
SURE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT
IN SERIOUS INJURY OR DEATH.
Systems where Air/Dirt with the switchable on/off magnet or Dirt Sepa-
rators with the switchable on/off magnet are installed should follow the
same process for Air/Dirt or Dirt Separators except should consider pro-
hibiting system flow followed by turning the magnet handle from the On
to the Off position prior to performing the blow down to ensure magnetite
is released from the internal magnet sleeve. CAUTION: MAINTENANCE
SHOULD ONLY BE UNDERTAKEN BY PROPERLY TRAINED AND
QUALIFIED PERSONNEL. NEVER OPEN A VESSEL UNTIL THE SYS-
TEM PRESSURE IS OFF AND THE VESSEL HAS BEEN ISOLATED
AND DRAINED. 4900s with Switchable on/off magnet option contain 1 or
more high power magnet.
THIS MAGNET SHOULD NOT BE REMOVED FROM
THE VESSEL WITHOUT CONSULTING THE FACTORY.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY
RESULT IN SERIOUS INJURY OR DEATH.
If loss of system fluid is a concern, the separator should be isolated from
the system by closing the adjacent valves as needed. Residual pressure
within the separator should be reduced by slowly opening the factory
installed blowdown valve. Make-up water may be introduced through
the flushing cock located on the side of the separator to promote further
rinsing of the internals of the separator without wasting system fluids.
