Introduction
Non-condensables like air, hydrogen,
nitrogen, and hydrocarbon gases
reduce the overall capacity of
the refrigeration system. Higher
pressures, which in turn causes
longer compressor runtime, longer
condenser fan runtime, higher
compressor discharge temperatures,
increase compressor power costs,
increase wear and tear on equipment,
increase leaks, reduce system
eciency, increase overall system
energy costs are all consequences of
non-condensables in the refrigeration
system.
In a refrigeration system non-
condensables can be introduced by:
• Inadequate system evacuation such
as servicing compressors, strainers,
valves, start-up, etc.
• Refrigerant additions
• Leaks from valve stem packings,
bonnet gasket, compressor shaft
seal, control transducers, etc.
• Separation of ammonia molecules
(hydrogen and nitrogen)
• Compressor oil breakdown
(hydrocarbon gases)
e base V200 Rapid Auto Purger
removes the non-condensable gases
from four purge points. With the
addition of up to two slave units, 36
purge points possible. is leads to
lower condensing pressure, runtime
of the compressors, and operating
costs.
Non-condensable indicators
are excessively high condensing
temperatures/pressures and
saturated temperature/pressure
deviations. One indicator is a higher
saturated condensing pressure/
temperature at the condenser for
the given outdoor air wet bulb
and heat rejection load. Another
indicator is the increasing dierence
between the observed condensing
pressure and the saturation
pressure corresponding to the liquid
refrigerant temperature exiting the
condenser.
Purge Points
e most common purge points
in a refrigeration system are at the
condenser drain, pilot receivers,
thermosyphon receivers, high
pressure receivers, liquid drain
header, equalizing lines, and low
velocity-high side areas.
Purge points should be located to
ensure no liquid refrigerant is drawn
by the purger. e Auto Purger V200
has a liquid drainer at the foul gas
inlet to prevent any liquid refrigerant
from entering the shell side of the
heat exchanger.
Auto Purging
e start of a purge cycle can
commence automatically, manually,
time based, central management,
and/or using the microprocessor. e
Auto Purger V200 can only purge one
point at any given time.
In automatic mode each purge point
is sampled for a minimum of ve
minutes. If the purge conditions are
not met within the sample time limit,
the Auto Purger continues to the next
purge point. When a purge point
meets the purge conditions within
the sample time limit the Auto Purger
starts the purge cycle. e purge
cycle shuts o when the non-purge
conditions are met.

A built in feature of the Auto Purger
is sleep mode. Sleep mode allows the
system to bypass purge points after
two cycles of not meeting the purge
conditions within the minimum
sample time of ve minutes. After the
Auto Purger samples each purge point
twice without a vent occurring, the
system will shut o for two hours.
Purge Cycle
e purge cycle consist of three main
operations: ll & pre-cool, separating
non-condensable gases & refrigerant,
and the release of non-condensable
gases.
1. Fill & Pre-Cool
Foul gas enters the V200 Auto
purger at the foul gas line. e
liquid drainer separates the liquid
refrigerant from the foul gas.
Using the suction line; the liquid
refrigerant from the liquid drainer
is transported to the shell side of the
heat exchanger.
Liquid makeup to the heat
exchanger is controlled by the
level sensor. As liquid refrigerant
boils o in the heat exchanger the
level drops. When the refrigerant
reaches a critical level the sensor
energizes the liquid solenoid,
opening the check valve, and letting
liquid refrigerant through to ll up
the heat exchanger. e level sensor
is set on a timer to prevent from over
lling the heat exchanger.

2. Separating Non-Condensable
Gases & Refrigerant
e foul gas enters the heat
exchanger through a check valve
with an orice and condenses
immediately. e non-condensable
gases remain in a gas state, because
the non-condensable gases require
lower temperatures to condense.
Condensed refrigerant and non-
condensable gases rise through the
heat exchanger and into the vapor
vent. As the liquid rises it lifts an
orice, ow controller, to the top of
the vapor vent allowing pressure to
build. Once the pressure exceeds
the high pressure check valve the
refrigerant then ows back into the
tube side of the heat exchanger.
e high pressure refrigerant
runs through the tubes of the heat
exchanger absorbing heat from the
high temperature foul gas of the
shell side of the heat exchanger. e
refrigerant begins to boil and vapor
refrigerant, free of non-condensable
gases, is returned to the plant by the
suction line.
Any oil that may collect in the V200
purger can be drained o from the
two oil drains. Before draining the
oil, shut-o the purger and close the
liquid and foul gas valves. Allow the
purger to pump out any remaining
refrigerant and close the suction
line valve. Use normal oil draining
precautions to prevent injury or
property damage.

3. Release of Non-Condensable Gases
As the refrigerant level drops in
the vapor vent the oat will fall
allowing the non-condensable gases
to escape through the orice. Non-
condensable gases will continue to
accumulate, producing an elevated
pressure. Once the pressure of the
non-condensable gases exceed
the set point of the vent solenoid
and vent check valve with orice,
the gases are then released into
the bubbler. At the same time the
vent solenoid is activated the water
supply solenoid is also activated.
Non-condensable gases and
residual amounts of refrigerant
entering the bubbler are diluted
into the water. As the water in the
bubbler rises it will overow the
drain tube and exit the drain line.
Once the vent line pressure drops
below the pressure switch set point
the vent solenoid and water supply
solenoid close.

Because both the water and vent
solenoids are energized at the same
time, this procedure must be done
prior to opening the system to
refrigeration. Failure to do so will
result in a venting of ammonia.
!
Installation
All purgers are packed for a maximum protection. Un-1.
pack carefully. Check the carton to make sure all items
are unpacked. Save the enclosed instruction for the
installer and eventual user.
Do not remove the protective coverings until the purger
is ready to be installed.
Mount the Rapid Auto Purger to a wall or structure that 2.
can easily handle its weight and installation hardware.
Make sure to leave access for servicing the unit if re-
quired. Pipe the unit into the refrigeration system along
with an electrical supply, water, and a water drain as
needed.
Note: Wire only one purge point solenoid to each control-
ler contact relay (See electrical wiring diagram).
Contractors need to follow a WPS (Welding3.
Procedure Specication) for all welding. e
procedure must be qualied and welder doing
the weld qualied to perform that procedure.
For welding the stainless steel 304L body to
carbon steel pipe, E309L and ER309L-15,-16, or
-17 ller metal is a common choice. Contractors
can develop their own standards and have them
qualied based on the equipment they use and
the environment they may encounter.
Before opening the purger to the refrigeration 4.

Symptom Possible Cause Solution
Water bubbler
cloudy.
Water supply turned off.
Hard water.
Venting ammonia.
Open water supply ball valve supplied with purger.
Check water solenoid coil for proper operation (Loose wire,
burned out). Replace if necessary.
Used treated water (softened). Clean bubbler on regular bases to
prevent severe clouding.
Check vent solenoid for proper operation. If bubbles are seen in
the water bubbler when idol, vent solenoid is leaking. Clean or
replace solenoid if needed.
Purger stays in
“Pre-Cool” mode,
will not purge.
Suction too high.
Liquid NH3supply off or obstructed.
RTD (#19) not reading accurately or no
display.
Verify Suction is below 4.4oC (40oF) - 4.0 bar (58.4 psig) for
R-717.
Adjust the A2 (#21) suction regulator to maintain 3 psig (If in or
near a vacuum). If suction is above 3 psig, remove setting from
A2 regulator by turning stem counter clock wise until it stops.
Check liquid ammonia solenoid, SV2 (#8), for proper operation
(Loose wire, burned out). Replace if necessary.
Check controller display for “Liquid Solenoid” pilot light.
Segment should be darkened if liquid is required. This is located
on the upper left side of the front panel (#1).
Check optical level sensor (#17) for proper operation (Loose wire,
defective sensor). Replace if necessary.
Check liquid supply orice (#11) for obstructions. Clean or
replace if necessary.
Note: RTD is factory calibrated and no eld adjustment is
required.
If the main controller displays “_ _ _” rather than an actual
temperature reading, check for loose wires. Check wire
loom from main board to cover for loose or damaged wires/
connections.
Replace RTD if necessary.
No temperature
reading on
controller display.
Loose RTD (#19) wire on main terminal
block.
Loose or damaged wire loom

Symptom Possible Cause Solution
Strong Ammonia
smell coming
from bubbler
(#14).
Water make up closed or restricted.
Leaking vent solenoid (#6).
Make sure the fresh water supply to the bubbler is not turned
off or being restricted. The purger is supplied with a shutoff ball
valve that should be in the full open position to start, and then
throttled back to control the ow rate into the bubbler.
Check the operation of the water makeup solenoid (#5). Verify
that the coil is energized when the vent cycle is active. The
magnetic eld can be veried with a small screwdriver touching
the top of the solenoid tube. It should be drawn to the tube if the
coil is powered and functioning properly. If the coil functions and
water still does not ow to the bubbler, check the supply lines for
obstructions.
Replace the water solenoid (#5) if necessary.
If bubbles are seen in the bubbler well after a vent has occurred,
the vent solenoid may be leaking.
Replace the solenoid if necessary.
Slave unit (#2)
not functioning (5
purge points and
up).
Master, slave communication cable
missing or damaged.
No power supplied to slave board.
Verify that the communications cable connecting the main purger
controller to the slave board is present, attached to the proper
terminals and is not damaged.
Check to make sure the green LED at the top of the slave unit
(#2) circuit board is ashing.
Verify the proper communication setting. This is done by pressing
the up & down arrow keys on the main controller (#1) at the same
time. Several attempts may be required as timing is critical. After
successfully completing this step, you should see a menu screen
that displays; Baud Rate, Parity, Temperature Scale and Slave ID.
(See step #7 under installation instructions)
Make sure the “baud” rate is set for 19200, “parity” even and
“slave ID” 01. Use the same keypad strokes to move and enter
settings as described in the bulletin under “Setup Instructions”.
Press the menu key to get back to the main screen. Check the
operation of the slave unit.
Make sure the power cable from the main purger controller to the
slave board is present, not damaged and properly connected.
Replace slave unit if necessary. (See both 4 point purger and
slave unit wiring diagram for proper wiring terminals)
Controller in
“sleep mode”, will
not purger
No foul gas present in system.
Damaged main controller board.
The purger controller will automatically go into “Sleep Mode” if
it has sampled every programmed purge point twice without a
vent occurring. It will stay in sleep mode for 2 hours then resume
its programmed cycle. You can override the sleep mode cycle
by simply pressing the “Enter” key on the controller. The sleep
mode feature will not be disabled and will repeat again if no vent
occurs.
Replace controller if necessary.
Note: all items with a (#) can be located in the V200 auto purger parts diagram.

Safe Operation (See Bulletin RSBCV)
People doing any work on a refrigeration system must be
qualied and completely familiar with the system and the
Refrigerating Specialties Division valves involved, or all other
precautions will be meaningless. is includes reading and
understanding pertinent Refrigerating Specialties Division
Product Bulletins and Safety Bulletin RSB prior to installation
or servicing work.
Where cold refrigerant liquid lines are used, it is necessary
that certain precautions be taken to avoid damage which
could result from liquid expansion. Temperature increase in a
piping section full of solid liquid will cause high pressure due
to the expanding liquid which can possibly rupture a gasket,
pipe or valve. All hand valves isolating such sections should
be marked, warning against accidental closing, and must
not be closed until the liquid is removed. Check valves must
never be installed upstream of solenoid valves, or regulators
with electric shut-o, nor should hand valves upstream of
solenoid valves or downstream of check valves be closed until
the liquid has been removed.
It is advisable to properly install relief devices in any section
where liquid expansion could take place. Avoid all piping
or control arrangements which might produce thermal or
pressure shock.
For the protection of people and products, all refrigerant
must be removed from the section to be worked on before a
valve, strainer, or other device is opened or removed. Flanges
with ODS connections are not suitable for ammonia service.
