CCI Thermal Technologies AC-R - Gas Pressure Regulator - Manual (Page 2)

INSTALLATION
Only qualified personnel should install a regulator.
Regulators should be installed, operated, and
maintained in accordance with applicable codes
and regulations, and CCI Thermal Technologies
instructions.
If the regulator vents fluid or a leak develops
in the system, it indicates that replacement is
required. Failure to take the regulator out of service
immediately may create a hazardous condition.
Personal injury, equipment damage, or leakage due
to escaping fluid or bursting of pressure-containing
parts may result if this regulator is overpressured or
is installed where service conditions could exceed
the limits given in the Specifications section, or
where conditions exceed any ratings or the adjacent
piping or piping connections.
To avoid such injury or damage, provide pressure-
relieving or pressure-limiting devices (as required
by the appropriate code, regulation, or standard) to
prevent service conditions from exceeding limits.
Additionally, physical damage to the regulator could
result in personal injury and property damage due
to escaping fluid. To avoid such injury and damage,
install the regulator in a safe location.
Clean out all pipelines before installation of the regulator
and check to be sure the regulator has not been
damaged or has collected foreign material during
shipping. For NPT bodies, apply pipe compound to the
male pipe threads. Install the regulator in any position
desired, unless otherwise specified, but be sure flow
through the body is in the direction indicated by the arrow
on the body.
Note
It is important that the regulator be installed so
that the vent hold in the spring case is
unobstructed at all times.
ADJUSTMENT
Each regulator’s outlet pressure is factory-set. If it
becomes necessary to increase outlet pressure, remove
the closing cap, Figure 1, and turn the adjusting screw
clockwise. Turn the adjusting screw counterclockwise
to decrease the outlet pressure. A pressure gauge is
needed to determine the regulator’s outlet setting after
adjustment. Always replace the closing cap
after adjustment.
OVERPRESSURE
PROTECTION
The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure
exceeds the maximum operating outlet pressure rating.
Overpressure protection should also be provided if the
regulator inlet pressure is greater than the safe working
pressure of the downstream equipment.
Regulator operation below the maximum pressure
limitations does not preclude the possibility of damage
from external sources or debris in the line. The regulator
should be inspected for damage after any
overpressure condition.
STARTUP
The regulator is factory set at approximately the midpoint
of the spring range or the pressure requested, so an
initial adjustment may be required to give the desired
results. With proper installation completed and relief
valves properly adjusted, slowly open the upstream and
downstream shutoff valves.
