SAFETY
GENERAL
APD equipment is designed to operate safely when the installation, operation and servicing are
performed in accordance with the instructions in this technical manual. For Service Center
locations, see the Service section of this manual.
SPECIAL NOTICES
Three types of special notices -- WARNINGS, CAUTIONS and NOTES are used in this
technical manual.
WARNINGS call attention to actions or conditions that can result in injury or death.
CAUTIONS call attention to actions or conditions that can result in damage to the equipment or
in abnormal performance.
NOTE
NOTES give important, additional information, explanations or recommendations related to
the appropriate topic or procedure.
WARNINGS and CAUTIONS, like other safety instructions, appear within rectangles in the text
where they are applicable. Because of their importance, they are summarized in this Safety
section, the first section to be read.
1
Safety
WARNINGS
AVOID ELECTRIC SHOCK. All electrical supply equipment must meet applicable codes and
be installed by qualified personnel.
Disconnect the power to the compressor before troubleshooting the electrical components.
Permit only qualified electrical technicians to open electrical enclosures, to perform electrical
checks or to perform tests with the power supply connected and wiring exposed. Failure to
observe this warning can result in injury or death.
AVOID INJURY. Never use compressed helium gas from a cylinder without a proper regulator.
Overpressure can cause personal injury if the system equipment ruptures.
During operation, some surfaces under the compressor’s cover become hot. Allow the
compressor to cool for 1/2 hour after shutdown before removing the cover for maintenance.
When handling pressurized gas lines and other pressurized equipment, always wear eye
protection. Never apply heat to a pressurized gas line or other pressurized components.
Disconnect gas lines only when the compressor is stopped. Disconnecting the cold head while
it is cold can create excessively high internal pressure as the gas warms. Material failure and
uncontrolled pressure release can cause injury.
Use two wrenches when disconnecting a gas line coupling to avoid loosening the cold head or
compressor coupling. Gas pressure can project the coupling with enough force to cause
injury.
The refrigeration system is charged with helium gas. Vent both supply and return Aeroquip
couplings to atmospheric pressure before disassembly, except when disconnecting gas lines.
Uncontrolled pressure release can cause injury.
Always vent a gas-charged component before beginning to disassemble its couplings. Gas
pressure can launch a loose coupling with enough force to cause injury.
CAUTIONS
PRESERVE YOUR WARRANTY. Modification to equipment without the consent of the
manufacturer will void the warranty.
Specifications require the use of 99.999% pure helium gas. Using a lesser quality of helium can
cause damage to the system and void the warranty.
AVOID GAS LEAKS. Check the condition of the gasket face seal on the male half of each
Aeroquip coupling. Be sure the gasket face seal is in place and the sealing surfaces on both
the male and female halves are clean before connecting. Replace the gasket face seal if it is
damaged or missing.
Keep the gas line couplings aligned when making or breaking a coupling connection. Leaks can
occur due to the weight of the gas line or due to a sharp bend near the connection.
2
Safety
CAUTIONS (continued)
AVOID CONTAMINATION. When checking the compressor for shipping damage, do not
connect gas lines and cold head. The components may become contaminated with
compressor oil.
Follow the charging or venting procedures to prevent reversed flow of system gas. Do not
charge through the supply coupling. Do not vent through the return coupling. Reversed flow
can contaminate the system with compressor oil.
A leaking coupling on an adsorber should not be repaired in the field. Consult a Service Center.
Venting the adsorber will introduce contaminants to the system, which cannot be removed in the
field.
PREVENT EQUIPMENT DAMAGE. Damage to gas lines can result from crimping by repeated
bending and repositioning.
Always thoroughly drain the coolant from the cooling circuit if the compressor is to be shipped or
stored.
If the compressor is wired for 380/415 (+10% -14%) V3~ electrical service, connecting to a
higher voltage may damage the control circuit. Similarly, if it is wired for 480 V3~, 60 Hz, it can
be damaged by connecting to 380/415 V3~.
Never pull a vacuum on the compressor or on the cold head. The motors will short circuit if
started.
After starting the system for the first time, to be certain that the water lines are properly
connected, check that the outlet water temperature is warmer than the inlet water.
For an installation using a water chiller or other circulating cooling system:
Use pure ethylene glycol with water for the coolant antifreeze solution. Do not use commercial
ethylene glycol sold for automotive cooling systems, which usually contains a fine grit material
that can damage the cooling system.
AVOID A MALFUNCTION. Repeatedly charging the system with helium gas rather than
locating and repairing gas leaks can cause a malfunction. Impurities are introduced at an
abnormal rate and can freeze in the cold head.
Do not allow air to get into the helium gas refrigerant of the system. Moisture from the
atmosphere can seriously degrade cold head performance.
AVOID EQUIPMENT FAILURE, CONTAMINATION OR A NUISANCE SHUTDOWN. Do not
tip the compressor greater than 10 degrees from horizontal, to avoid flowing oil into unwanted
places.

INTRODUCTION
Helium Compressor Models HC-10 and HC-10L
The compressors are designed to deliver high-pressure, oil-free helium gas to cryogenic
refrigerators. Cold head cables are used with the compressor to supply electrical power to cold
heads. Self-sealing couplings allow for easy connection to and disconnection from the rest of
the closed-cycle cryogenic refrigeration system.
The information in this manual pertains only to the HC-10 (high voltage model) and the HC-10L
(low voltage model) Compressors. Other components used to form an operating system are
described in separate technical manuals.
Pressures are stated as gauge, not absolute. Pressure units are bar and pounds per square
inch (psig). For reference:
1 bar = 14.5 Psig.
1 MPa = 10 bar
Definition of Symbols used in this manual and on equipment

DESCRIPTION
Components
Helium High and Low Pressure Couplings - Both are self-sealing, size 8, male (8M),
Aeroquip, bulkhead couplings and are the points of connection on the front panel for the gas
lines.
Helium Fill Port - A size 4, male (4M), Aeroquip coupling located on the front of the compressor
is used for charging or venting helium gas refrigerant.
Water In and Out Fittings - Both fittings are ½" MNPT mounted on the front panel.
Pressure Gauge - Indicates gas pressure in the supply line. When the compressor is not
running, the gauge located on the compressor’s front panel shows the equalization pressure.
Cold Head Power Receptacle - Mounted on the front panel for connecting a cable to supply
electrical power from the compressor to the cold head.
Circuit Breakers - Two panel-mounted circuit breakers, one in the main power supply and one
for the control circuit, protect the compressor from electrical overload.
Fuses - Five (5) 0.4 AT fuses are located in the electrical box. See Replace Fuses.
Electrical Chassis Box - The electrical box contains electrical components and connections
and distributes power to all system circuits.
Compressor Power Cord - The power cord supplies electrical power to the compressor.
Compressor - The helium, scroll compressor has a hermetically sealed motor.
Heat Exchanger - Uses water to cool the high-pressure helium from the compressor and the
compressor’s lubricating oil.
Oil Separator - Removes most of the entrained oil from the gas stream. This unit needs no
servicing or replacement.
Oil Capillary - The capillary returns oil collected in the oil separator sump to the compressor for
recycling.
Adsorber - The adsorber removes any oil and moisture the gas is carrying which did not drop
out in the separator. The adsorber has a finite life and must be replaced every 13,000 operating
hours.
Pressure Relief Valve - The relief valve prevents the compressor from operating at an unsafe
pressure by venting to the atmosphere.
Oil Filter - A filter in the oil separator drain line protects the return oil capillary.
Water High Temperature Switches - One each is located in the “water in” line and in the
“water out” line. They shut down the compressor if the inlet or the outlet water temperature is
too high. High outlet water temperature indicates low water flow. The switches reset
automatically after cooldown.
6
Description
Compressor High Temperature Switch - Located inside the compressor motor, the switch
senses compressor motor temperature and stops the motor if the temperature is too high. The
switch resets after cool down.
Supply Gas High Temperature Switch - Opens if the temperature of the high-pressure helium
from the compressor is too high. The switch resets after cool down.
Oil Injection Orifice - This orifice is installed in the oil return manifold and controls the flow rate
of oil returned to the compressor.
Internal By-pass Valve - The internal by-pass valve opens to allow the compressor to be
operated in the stand-alone mode or when the system gas lines are disconnected, to avoid
overloading the motor.

INSTALLATION
Introduction
Install the HC-10 or the HC-10L Compressor, Cold head, Cable and the Gas Lines according to
the following procedures.
To prevent contaminating the components or the system, it is important to follow the procedures
in this manual step by step.
NOTE
Be sure to have 99.995% pure helium gas available for installation of the system.
See Refrigerant Quality in Specifications.
Lift the Compressor
Remove the shipping container from the compressor. Insert and tighten the three- (3) furnished
eyebolts into the top of the compressor. See Figure 1.
Unpacking, Inspection and Pressure Check
1.
Remove all components from their shipping containers and inspect them for damage.
AVOID EQUIPMENT FAILURE, CONTAMINATION OR A NUISANCE
SHUTDOWN. Do not tip the compressor more than 10 degrees from horizontal
to avoid flowing oil into unwanted places.
AVOID CONTAMINATION. When checking the compressor for shipping
damage, do not connect gas lines and cold head. The components may become
contaminated with compressor oil.
NOTE
Retain the shipping containers if reusable for returning the components to the
factory if reconditioning is required.
2.
Inspect the following:
2.1
Check the Tip-N-Tell sensor mounted on the compressor. If the Tip-N-Tell sensor
shows no mishandling and there is no apparent physical damage, proceed to the
section Compressor.
If the Tip-N-Tell sensor indicates mishandling (arrow point is blue), proceed to
either Step 2.2 or 2.3:
2.2
The equalization pressure is within specifications.
15
Installation
AVOID ELECTRIC SHOCK. All electrical supply equipment must meet
applicable codes and be installed by qualified personnel.
AVOID ELECTRIC SHOCK. Permit only qualified electrical technicians to open
electrical enclosures, to perform electrical checks or to perform tests with the
power supply connected and wiring exposed. Failure to observe this warning
can result in injuries or death
Connect power to the compressor. See the next sections Compressor, Change Electrical
Service Connections and Compressor Checkout. Test run the compressor for two (2)
hours minimum. If there are no problems during this time, stop the compressor and
proceed to assemble the system.
If the compressor shuts down during the two- (2) hour test, contact the nearest SHI-APD
Service Center.
2.3
If the equalization pressure is outside the specified range or there is physical
damage to the compressor enclosure or the compressor has been on its side or
upside down for an extended period of time (more than one hour), contact the
nearest SHI-APD Service Center.
If the compressor has been momentarily tipped (less than one hour) and the
equalization pressure is within specifications, allow it to stand upright for two hours
before running the two-hour test in Step 2.2.
PREVENT EQUIPMENT DAMAGE. If the HC-10 compressor is wired for 400
V3~, 50Hz (400 +10% -14% V3~) electrical service, connecting to a higher
voltage may damage the control circuit. Similarly, if it is wired for 480 V3~, 60
Hz, it can be damaged by connecting to 400 V3~.
Compressor
Place the compressor in a location that is protected from the elements and where the ambient
temperature will always be within the range of 4° C to 40° C (40° F to 104° F).
PREVENT EQUIPMENT DAMAGE. Always thoroughly drain the coolant from
the cooling circuit if the compressor is to be shipped or stored.
The compressor must be installed base down, within 10 degrees of horizontal, and preferably at
a height convenient for making connections and reading the pressure gauge.
16
Installation
Allow 600-mm (24”) space in front of the compressor for access to electrical, water and gas
connections. Allow 600-mm (24”) on the left side (when facing the front) of the compressor for
maintenance of the adsorber.
The following installation procedures are based on standard arrangements of equipment, using
SHI-APD Cryogenics standard components.
Mains power input wires to the HC-10 (high voltage model) Compressor must be
connected to the proper transformer terminals inside the compressor.
Use terminals labeled 400 for 380/415 (+10% -14%) V3~, 50 Hz electrical service.
Use terminals labeled 480 for 480 (+10% -14%) V3~, 60 Hz electrical service.
Look through the transparent Power Selection Access Cover (shown in Figure 1) to determine
and confirm that the wires are connected to the correct terminals to suit the user’s electrical

AVOID ELECTRIC SHOCK. All electrical supply equipment must meet
applicable codes and be installed by qualified personnel. Permit only qualified
electrical technicians to open electrical enclosures, to perform electrical checks
or to perform tests with the power supply connected and wiring exposed. Failure
to observe this warning can result in injury or death.
PREVENT EQUIPMENT DAMAGE. If the HC-10 Compressor is wired for 400
V3~, 50 Hz (380/415 +10% -14% V3~) electrical service, connecting it to a
higher voltage may damage the control circuit. Similarly, if it is wired for 480
V3~, 60 Hz, it can be damaged by connecting to 400 V3~.
The compressor should be operated before being connected to the other system components.
1.
Connect coolant supply and return lines to the water in and water out fittings on the front of
the compressor. Connect the supply line to the user’s cooling water or coolant supply
valve. Turn on the coolant and check the water lines for leaks. Tighten the fittings if
necessary. See Specifications for cooling requirements.
2.
For the HC-10 (high voltage model) Compressor only, look through the power selection
access cover to be sure the compressor is wired to the correct voltage terminals for the
electrical service.
3.
Connect the power cord to the mains power receptacle on the front panel of the
compressor. Be sure to lock the plug in place with the tab on the locking lever. Connect
the power cord to the appropriate power source.
4.
Close the main power circuit breaker (handle is up). Close the control system circuit
breaker. Push the ON button. Run the compressor for ten (10) minutes, then stop.
5.
While the compressor is running, lightly touch the water supply and return lines. The
return (water out) line should be warmer. If the return water line is cooler than the supply
(water in) line, stop the compressor and reverse the water connections.
18
Installation
NOTE
The compressor has reversed-phase protection to prevent it from running in
reverse. If it does not start and the LCD displays “Phase Seq – ERR”, disconnect
the power cord and interchange any two wires (except ground) at the compressor’s
power cord plug. Refer to the Troubleshooting section in this manual.
NOTE
If the compressor starts but does not build pressure, turn it off immediately. It could
be running in reverse despite the above-mentioned phase monitor relay. Be sure to
rewire the power supply correctly after electrical work. See the Troubleshooting
section.
This completes the checkout of the compressor.
Install the Gas Lines
Tools required: Open-end wrenches, 1", 1 1/8", 1 3/16".
Gas lines are shipped with protective dust plugs. Do not remove the plugs until the gas lines
are ready to be attached. All bending and routing of gas lines should take place with plugs
in place.
PREVENT INJURY. Always wear eye protection when handling pressurized gas
lines and other pressurized equipment. Never apply heat to a pressurized gas
line or other pressurized components.
PREVENT EQUIPMENT DAMAGE. Damage to gas lines can result from
crimping by repeated bending and repositioning.
NOTE
Be sure to have 99.995% pure helium gas available at the installation site in
case gas needs to be added to the system. See Refrigerant Quality in
Specifications in this manual.
1.
Identification labels are furnished with the gas lines. Before installing the gas lines,
identify each with an appropriate label, SUPPLY (high pressure, color-coded red) or
RETURN (low pressure, color-coded green) by applying a label adjacent to each
Aeroquip coupling. See Figure 3.
NOTE
Supply and return gas lines are identical. Labels are used to prevent making a
wrong connection at installation or at reassembly following maintenance.
19
Installation

3.
Remove the dust caps from the compressor’s supply and return gas couplings.
4..
Remove the dust plugs from the Aeroquip couplings on one end of each of the gas lines.
Connect the gas lines to the compressor’s high-pressure (supply) and low-pressure
(return) couplings. Use two wrenches to tighten the coupling. Torque all couplings to
47 ± 7 Nm (35 ± 5 ft. lbs.) See Figure 4. Tighten each coupling before proceeding to the
next one.
AVOID GAS LEAKS. Check the condition of the gasket face seal on the male
half of each Aeroquip coupling. Be sure the gasket seal is in place and the
sealing surfaces on both the male and female halves are clean before
connecting. Replace the gasket seal if it is damaged or missing.
Keep the gas line couplings aligned when making or breaking a coupling
connection. Leaks can occur due to the weight of the gas line or due to a sharp
bend near the connection.
NOTE
Retain the dust caps and plugs to re-cover the couplings when they are not in
use. They protect the couplings from damage and prevent the entry of
contaminants.
5.
Connect the SUPPLY gas line to the SUPPLY coupling on the cold head. Use two
wrenches. Tighten the coupling to 47 ± 7 Nm (35 ± 5 ft. lbs.).
6.
Connect the RETURN gas line to the RETURN coupling on the cold head. Tighten the
coupling to 47 ± 7 Nm (35 ± 5 ft. lbs.).
20
Installation
The system equalization pressure, shown by the compressor gauge after all components have
been connected, will determine if charging or venting is required.
Figure 4 Connect Gas Line to Compressor or Cold head
This completes the installation procedure.
Prestart Check
1.
Check that the cooling water lines are connected. Verify that the supply water is
connected to the water in connection. Turn on the coolant and check the lines for
leaks. Tighten the fittings if necessary. See Cooling Requirements in Specifications.
2.
Check that all electric cables are connected:
a.
b.
Power to the compressor.
Cold head cable.
3.
Check that the electrical power supply is switched on.
4.
When the compressor is at room temperature, 20° C (68° F), the pressure gauge
should indicate the equalization pressure. Higher or lower temperatures will result in
correspondingly higher or lower pressures, but these pressure changes are normal.
Abnormally lower readings indicate that some of the gas charge has been lost.
System Diagnostic Connector
A female DB-25 connector is located on the front panel to supply remote indication of the
operating status of the compressor. See Figure 8 in the Troubleshooting section of this manual
for connection information.

OPERATION
Starting
Close the main power circuit breaker. Close the control system breaker. Push the ON button.
The compressor and the cold head will start.
Stopping
Push the OFF button. The compressor and the cold head will stop. Open the main power circuit
breaker (push handle down).
Restarting After a Power Failure
When the power comes on, the microprocessor will determine if the last shutdown was due to a
power outage. If the operator turns off the system by the main breaker, it will be detected as a
power outage. If the compressor power was interrupted by a power outage, the compressor
and the cold head will restart automatically after a one (1) second delay.
If the compressor stops for other reasons, compressor troubleshooting is required.
PREVENT EQUIPMENT DAMAGE. After starting the system for the first time,
to be certain that the water lines are properly connected, check that the outlet
water temperature is warmer than the inlet water.

MAINTENANCE
AVOID EXPOSURE. People with pacemakers or ferrous implants should avoid
exposure to strong magnetic fields. The long-term effects of high magnetic fields
are not well understood. Keep personal exposure to a minimum.
AVOID INJURY. When released in a high magnetic field, ferrous tools and parts
can become hazardous projectiles.
PREVENT DEGRADED PERFORMANCE. Failure to replace the adsorber can
result in oil carryover to the cold head, degraded performance and difficult oil
cleanup.
AVOID CONTAMINATION. A leaking coupling on an adsorber should not be
repaired in the field. Consult a Service Center. Venting the adsorber will
introduce contaminants to the system that cannot be removed in the field.
PRESERVE YOUR WARRANTY. Modification to equipment without the consent
of the manufacturer will void the warranty.
HC-10/HC-10L Compressor Adsorber Replacement
The compressor’s adsorber should be replaced every 13,000 operating hours (18 months). The
used adsorber has no salvage or repair value. Venting the compressor is not required when
replacing the adsorber because the couplings are self-sealing.
Adsorber Removal
Tools required:
#2 Phillips screwdriver
Open-end wrenches, 1", 1 1/8", 1 3/16"
1. Stop the compressor and disconnect the power to the compressor.
2. Disconnect the supply (red) gas line from the supply coupling on the compressor. Screw a
dust plug into the disconnected gas line.
NOTE
Always hold the stationary nut on the gas line coupling with one wrench while
turning the moveable coupling with the other wrench.
3. Remove the compressor’s cover panel.
25
Maintenance
4. Disconnect the self-sealing coupling on the inlet side of the adsorber. Use two wrenches.
AVOID EQUIPMENT FAILURE, CONTAMINATION OR A NUISANCE
SHUTDOWN. Do not tip the compressor greater than 10 degrees from
horizontal, to avoid flowing oil into unwanted places.
5. Use a Phillips screwdriver to remove the two screws holding the adsorber to the base.
6. Remove the locknut on the Aeroquip supply coupling on the front panel.
7. Pull the adsorber back until the supply coupling clears the front panel. Remove the
adsorber. Remove the lockwasher from the Aeroquip supply coupling. Retain all hardware

This completes the procedure for replacing an adsorber.
26
Maintenance
Used Adsorber Venting and Disposal
For safe disposal of the used adsorber:
1.
A venting adapter fitting is included with the new adsorber. Attach it to one of the selfsealing couplings on the used adsorber. Vent the used adsorber to atmospheric
pressure.
2.
Discard the used adsorber and the adapter fitting.
Charging or Venting
Charging or venting is required whenever the equalization pressure of the system is outside the
range as stated in the Specifications. See Specifications for equalization pressures at different
ambient temperatures.
Venting a component to atmospheric pressure is required if the component needs to be
disassembled for repairs or maintenance, including repairs to its self-sealing couplings.
AVOID INJURY. Never use compressed helium gas from a cylinder without a
proper regulator. Overpressure can cause personal injury if the system
equipment ruptures.
AVOID CONTAMINATION. Follow the charging and venting procedure to
prevent reversed flow of system gas. Do not charge through the supply
coupling. Do not vent through the return coupling. Reversed flow can
contaminate the system with compressor oil.
NOTE
Adapter fittings for charging and venting are available as optional service tools
from SHI-APD. See the Parts section of this manual.
Charging Procedure
Tools required:
Adapter fitting with valve, 4F Aeroquip, P/N 253757B.
Open-end wrenches, 5/8", 3/4".
Helium gas cylinder with pressure regulator and charge line.
AVOID A MALFUNCTION. Repeatedly charging the system with helium gas
rather than locating and repairing gas leaks can cause a malfunction. Impurities
are introduced at an abnormal rate and can freeze in the shield cooler.
To charge helium gas to the system:
1.
Stop the compressor.
27
Maintenance
2.
Locate an adapter fitting, P/N 253757B. Slightly open the adapter fitting’s valve. Use two
wrenches to attach it to the 4M Aeroquip helium fill port on the front of the compressor.
Close the valve.
3.
Connect a charge line to the pressure regulator of a helium gas cylinder containing
99.995% pure helium with a dew point less than -50° C (-58° F) at 20.7 bar (300 psig).
4.
When connecting the charge line to the adapter fitting, thoroughly purge the charge line
from the regulator. Slightly open the valve on the adapter fitting and release a small volume
of gas from the compressor. While both the charge line and the adapter fitting are purging,
connect them together. It is important to remove all air contaminants to prevent them from
entering the system.
5.
Adjust the regulator to the required equalization pressure. See the Specifications section in
this manual. Slowly open the valve on the adapter fitting. Charge the system with helium
gas to the equalization pressure.
6.
Close the valves on the adapter fitting and on the gas cylinder.
7.
Disconnect the charge line from the adapter fitting. Remove the adapter fitting. Store the
charge line to keep it clean.
8.
Leak check the Aeroquip couplings using the procedure on page 31 in this manual
This completes the charging procedure.
Venting Procedure to Adjust the Equalization Pressure
Tools required:
Adapter fitting with valve, 4F Aeroquip, P/N 253757B.
Open-end wrenches, 5/8", 3/4".
NOTE
This venting procedure is not to be used for gas cleanup of the compressor.
To vent helium gas from the system:
1.
Stop the compressor.
2.
Be sure the valve on the adapter fitting P/N 253757B is closed. Using two wrenches, install
this adapter fitting on the 4M Aeroquip helium fill port.
3.
Slowly open the valve on the adapter fitting. Vent the system until the required equalization
pressure is attained. See Specifications. Close the valve on the adapter fitting.
4.
Remove the adapter fitting from the compressor. Use two wrenches.
This completes the venting procedure to adjust the equalization pressure.
28
Maintenance
Gas Cleanup
If the equalization pressure shown by the compressor’s pressure gauge is less than 1.4 bar
(20 psig), gas cleanup of the compressor is required. Look for helium leaks. Perform gas
cleanup.
When all system components are connected and the equalization pressure of the system is less
than 1.4 bar (20 psig), check for leaks. Repair leaks. Perform gas cleanup of the system.
PREVENT EQUIPMENT DAMAGE. Never pull a vacuum on the compressor or
on the cold head. The motors will short circuit if started.
AVOID INJURY. Extreme cold can cause frostbite. When handling system
components, be careful not to touch any frosted parts.
AVOID INJURY. Do not splash cryogenic liquids on any areas of clothing or
exposed skin. Damage to skin tissue will result. Always wear eye protection.
AVOID ASPHYXIATION. Be sure the work area is well ventilated.
AVOID INJURY. For a cold head mounted in an evacuated sleeve that remains
cold, break the vacuum with helium. Do not allow air or nitrogen to enter the
sleeve. Air and nitrogen can liquefy and freeze, then create high pressure when
they warm.
AVOID INJURY. When released in a high magnetic field, ferrous tools and parts
can become hazardous projectiles.
AVOID EXPOSURE. People with pacemakers or ferrous implants should avoid
exposure to strong magnetic fields. The long-term effects of high magnetic fields
are not well understood. Keep personal exposure to a minimum.
29
Maintenance
AVOID INJURY. Disconnect gas lines only when the compressor is stopped.
Disconnecting the cold head while it is cold can create excessively high internal
pressure as the gas warms. Material failure and uncontrolled pressure release
can cause injury.
Tools required:
2 adapter fittings with valve, 8F Aeroquip, 255919B2.
Open-end wrenches, 1", 1 1/8" and 1 3/16".
Helium gas cylinder with pressure regulator and charge line.
Gas cleanup is required if the compressor’s interior has been opened to the atmosphere
or the equalization pressure is 1.4 bar (20 psig) or lower. Gas cleanup is performed with
the compressor disconnected from the other system components.
NOTE
If the compressor’s interior has been exposed to the atmosphere for an extended
period, gas cleanup may not suffice to guarantee system gas purity. Contact an
SHI-APD Service Center.
1.
Disconnect the gas lines from the compressor. Plug the disconnected gas line couplings.
2.
Locate two adapter fittings P/N 255919B2. Be sure their valves are closed. Attach them to
the supply and return Aeroquip couplings on the compressor.
3.
Connect a charge line to the pressure regulator of a helium gas cylinder containing 99.995%
pure helium gas with a dew point less than -50° C (-58° F) at 20.7 bar (300 psig). Adjust the
gas cylinder pressure regulator to 0.35 bar (5 psig).
4.
While connecting the charge line to the adapter fitting on the compressor’s return coupling,
thoroughly purge the charge line from the regulator. It is important to remove all air
contaminants to prevent them from entering the system.
5.
Adjust the pressure regulator to 15.2 bar (220 psig). Open the valve on the adapter fitting
and charge the compressor to 15.2 bar (220 psig).
6.
Close the valve on the adapter fitting used for charging.
7.
Run the compressor for at least 30 minutes to heat the oil to operating temperature.
Stop the compressor.
8.
Open the vent valve on the supply coupling of the compressor. Watch the compressor’s
pressure gauge. When the pressure falls to 0.35 to 0.7 bar (5 to 10 psig), close the vent
valve. Open the charge valve to increase the pressure to 15.2 bar (220 psig). Close the
charge valve.
9.
Start the compressor.
10.
After running 30 to 45 seconds, stop the compressor. Open the vent valve and vent the
compressor to 0.35 to 0.70 bar (5 to 10 psig). Close the vent valve.
30
Maintenance
11.
Repeat steps 8, 9 and 10 ten (10) times, and then go to Step 12.
12.
Open the charge valve on the adapter fitting. Charge the compressor to the equalization
pressure. Close the charge valve.
13.
Allow the compressor to cool. Read the pressure gauge with the compressor at 20° C
(68° F). Adjust the equalization pressure by charging or venting to conform to the
Specifications.
14.
Close the gas cylinder valve and adjust the pressure regulator to zero psig.
15.
Disconnect the charge line from the adapter fitting. Store the charge line to keep it clean.
16.
Remove both adapter fittings.
17.
If other components need cleaning, perform the appropriate procedures. Otherwise,
reconnect the supply and return gas lines. Torque the gas line couplings to 47 ± 7 Nm
(35 ± 5 ft. lbs.).
18.
Leak check the Aeroquip couplings. See Leak Check.
This completes the gas cleanup procedure for the compressor.
Leak Check
In addition to identifying suspected leaks, check the compressor for helium leaks each time
it has undergone any amount of disassembly. Use a helium mass spectrometer leak detector if
available. Follow its manufacturer’s instructions.
If a leak detector is not available, use a commercial leak detection solution such as Snoop®.
However, small leaks may not be detected. Also, it is important to:
•
•
•
fully coat the joint being tested;
allow time for bubbles to form at a small leak;
look carefully for the smallest bubble formations.
After solution testing is completed, use water to wash all residues from joints and couplings.
In either method of testing, do not assume that the first found leak is the only one. Check all
joints.
Leak detection by instruments can be misleading. Leaking gas can form patterns that indicate
leaks at sound joints. Large leaks or a high gas concentration can make isolation difficult.
Leaks occur most frequently at threaded joints. However, they can occur also at brazed and
welded joints.
The flat gasket in the face of the Aeroquip male coupling seals the joint. A leak at this gasket
face seal can be detected only when a gas line is connected. A leak here can be caused by:
•
•
•
•
•
the coupling not fully tightened;
a worn, damaged, or missing gasket seal;
dirt on or under the gasket seal;
dirt on the female coupling’s mating surface;
damaged parts on either coupling which prevent proper mating or sealing.
31
Maintenance
Leak Repair
Leaks in flexible metal tubing cannot be repaired. Discard the damaged gas line and install
a new one.
Leaks at welded joints require special skills to repair. Consult a SHI-APD Service Center.
Replacing worn or damaged parts can repair leaks at the self-sealing couplings. Vent the
compressor before beginning to disassemble it.
Tightening the coupling frequently stops leaks at threaded joints. Continued leakage after
tightening requires coupling repair. Install new O-rings or Teflon tape as required.

TROUBLESHOOTING
AVOID ELECTRIC SHOCK. Permit only qualified electrical technicians to open
electrical enclosures, to perform electrical checks or to perform tests with the
power supply connected and wiring exposed. Failure to observe this warning
can result in injury or death.
AVOID ELECTRIC SHOCK. Disconnect the power to the compressor before
troubleshooting the electrical components.
AVOID INJURY FROM BURNS. During operation, some surfaces under the
compressor’s cover become hot. Allow the compressor to cool for ½ hour after
shutdown before removing the cover for maintenance.
PRESERVE YOUR WARRANTY. Modification to equipment without the
consent of the manufacturer will void the warranty.
Compressor Motor
Compressor motor checks for winding continuity, resistance and grounding will isolate most
motor electrical problems. When the checks indicate a faulty compressor, a replacement
is needed. Contact a Service Center.
Winding Continuity, Grounding and Resistance Checks
Tools needed:
Ohmmeter or multimeter
#2 Phillips screwdriver
The following electrical measurements to check the compressor motor may be made either at
the compressor terminals or at the motor contactor.
1.
Disconnect the power to the compressor.
2.
Remove the cover, side panels and rear panel from the compressor.
3.
Remove the terminal box cover from the side of the compressor motor to expose the
three terminals T1, T2 and T3. It is not necessary to remove the wires from their terminals.
4.
With an ohmmeter, check the resistance across pairs of compressor terminals.
Resistance should be about 2.6 ± 10% ohms in each leg, at room temperature. If there is
no continuity, there is an open circuit in the motor windings. Consult an SHI-APD
Service Center.
35
Troubleshooting
5.
With the ohmmeter, check for continuity between the motor windings and one of the
unpainted tubes entering the compressor housing. Use the three compressor terminals
and one of the stainless steel tubes from the compressor. If there is continuity, there is a
short circuit to ground in the motor windings. Consult an SHI-APD Service Center.

diagnostics as required
If the compressor has been shut down by one of these interlocks, do not restart until the
problem has been found and corrected. Refer to the Troubleshooting Guide to identify the
problem.
In the event of a shutdown error, the compressor motor and cold head valve motor are
turned off. The microprocessor will annunciate the error condition via 24 VDC signals at the
System Diagnostics Connector and via the LCD Display. Signals are available on the 25-pin
connector for output to an external device. See Figure 8.
Clearing Error Conditions
When an error is corrected, the message(s) can be cleared from the display and the system
diagnostics connector by any of the following procedures:
•
•
•
Apply a momentary signal to pin 3 of the system diagnostics connector, or
Press the ON and DISPLAY buttons simultaneously, or
Open the control system circuit breaker, then close it to turn the power on.
Restarting after an Error Condition
When the shutdown is caused by any of the high-temperature switches, the compressor will
restart only after it has cooled enough for the switch to close. After waiting for the compressor
to cool, clear the error message then push the ON button to restart. Should the compressor fail
to start, allow more cooling time. Repeat the restart procedure. Check cooling water
temperature and flow. Compare with Specifications.
The motor high winding temperature relay automatically resets after the compressor shuts down
and the relay cools. This typically takes about 30 minutes. To restart the compressor, clear the
error message then push the ON button. If the compressor fails to start, allow more cooling
time. Repeat the restart procedure.
If the circuit breaker opens, reset it by pushing the lever to OFF (handle down), then to ON
(handle up). The compressor and the cold head should start automatically.
