Installation |
Sun Cooling Door 5600 modules must be securely mounted on the rear of the Sun cabinet. No cutting or drilling is required to attach the modules; all mounting features required are fabricated at the factory.
The module’s dimensions are listed in TABLE 3-1 and shown in FIGURE 3-1.
FIGURE 3-1 Sun Cooling Door 5600 Dimensions
Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection systems in the European Community market and operating with fluorinated greenhouse gases (f-gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmosphere.
The F-Gas Regulation requires operators to use all measures that are technically feasible and do not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to recover f-gas as part of regular, scheduled maintenance or decommission.
Refer to the full regulation for additional details.
| Note - Only properly trained and qualified personnel should service, charge or repair the system. |
The Sun Cooling Door 5600 module mounts on the rear of a Sun rack or chassis with 14 M6 x 12mm bolts that secure the Sun Cooling Door 5600’s frame to the rack or chassis. This operation will require two persons to lift the Sun Cooling Door 5600 and hang it on bolt heads on the Sun rack or chassis.
| Note - Risk of improper installation. Can cause equipment damage. The Sun Cooling Door 5600 must be installed by properly trained and qualified Liebert service personnel. |
Before beginning to attach the Sun Cooling Door 5600 module on the Sun rack or chassis, remove the rear door from the rack or chassis. Refer to Appendix A for details.
1. Find the M6 x 12mm bolts that were shipped with the Sun Cooling Door 5600 and insert one in the top hole on each side of the rack.
2. Tighten the two bolts with a 10mm wrench, leaving enough space between the bolts’ flanged head to accept the thickness of the Sun Cooling Door 5600’s frame (2-3mm).
3. Lift the Sun Cooling Door 5600 by the handles on the side, match the keyhole slots to the bolts in the Sun rack or chassis and hang the Sun Cooling Door 5600 on the protruding bolt heads.
4. Insert the remaining bolts and tighten snugly with a 10mm wrench.
5. Tighten the bolts in the keyhole slots snugly with a 10mm wrench.
6. Remove the four handles (two on each side).
Each is attached with two socket head bolts with 6mm Allen key heads. Use a 6mm Allen wrench to remove the handles; store the handles for use in case the Sun Cooling Door 5600 must be removed from the Sun rack or chassis.

The piping assembly and connection means used for piping in the Sun Cooling Door 5600 system are similar to those used in conventional refrigeration systems. Observe all standard practices during installation and startup to prevent damage and contamination.
The Sun Cooling Door 5600 has supply and return connection points on the top of each module. The supply piping connection is 1/2" outside diameter copper pipe, and the return connection is 5/8" outside diameter copper pipe. The supply fitting is equipped with a Schrader valve. The door contains a shipping charge of dry nitrogen that should be purged before installation.
1. Remove the cap from each Schrader valve on the Sun Cooling Door 5600 module and vent the shipping charge of nitrogen gas.
2. Find and open the bag containing the supply and return connectors that were shipped with the Sun Cooling Door 5600.
3. Attach the supply and the return connectors to the top of the Sun Cooling Door 5600. Position the connectors so that they do not interfere with rack use.
The supply fitting connection is 7/8" outside diameter copper pipe, and return fitting connection is 1-1/4" outside diameter copper. The supply fitting attaches to the right side of the Sun Cooling Door 5600 when viewed from behind and the return fitting attaches to the left side (refer to FIGURE 3-3).
Use the wrenches and torques specified in TABLE 3-2.

The Sun Cooling Door 5600 module system requires using the Liebert XD prefabricated piping assembly. The prefabricated piping is compatible with the Liebert XD Flex Pipe, which is also required to use Sun Cooling Door 5600 modules. For information, refer to the Liebert XD manuals, which can be found on Liebert’s web site:
FIGURE 3-4 Sun Cooling Door 5600 with Liebert XD Flex Hose Attached to Refrigerant Supply and Return Pipes
1. Remove the caps on the supply and return lines on the top of the Sun Cooling Door 5600.
2. Lubricate the threads, diaphragm and O-ring with one or two drops of mineral oil, taking care to minimize oil on surfaces that will be exposed to refrigerant.
3. Connect the line-set coupling finger-tight.
4. Make sure the Schrader valve is properly oriented; refer to the label on the top of the Sun Cooling Door 5600.
5. Hold the backup hex nut with a wrench while tightening the swivel nut.
6. Tighten the swivel nut on the female coupling until it is seated or a definite resistance is felt.
7. Once a definite bottoming resistance is felt (as in metal to metal), place a mark lengthwise from the swivel nut to the backup hex with an etching tool or other marker and tighten the swivel nut on the female coupling an additional 1/4 turn.
8. Tighten the 7/8" supply fittings to 94lb-ft.
9. Tighten the 1-1/4return fittings to 150lb-ft.
10. Mark the female and male coupler with an etching tool or other marker for future reference.
The Sun Cooling Door 5600 module system with optional flexible piping requires use of the Liebert XD prefabricated piping assembly. The prefabricated piping is compatible with the Liebert XD Flex Pipe required to attach to the Sun Cooling Door 5600 modules.
For additional information, refer to the Liebert X-treme Density System Design Manual, SL-16655, available at the Liebert web site:
This operation requires two properly trained and qualified Liebert service personnel.
Before connecting the Sun Cooling Door 5600 with Liebert XD Flex Pipe to the prefabricated piping mains, check the entire system for leaks.
Check the holding charge in the Sun Cooling Door 5600 to ensure that the unit has no leaks.
Read all instructions before beginning installation.
1. Determine the port locations on the two supply and two return lines overhead.
2. Make sure the service valve for each port is closed.
3. Remove cap for only the required ports. Do not remove caps from the unused ports.
4. Once Step 3 has been completed, remove the pipe plugs that are supplied on the Liebert XD Flex Pipe.
5. Use system refrigerant to lubricate the face of the male coupling half, including the poppet valve face and the stainless steel delta ring.

Notice - Risk of overtightening of couplers. Can cause equipment damage. See FIGURE 3-6 and the related Figure Legend for correct coupler tightening specifications. |
6. Thread the return couplers together. The return couplers are the larger of the couplers.
7. Use the adjustable wrench to hold the fixed side of the female coupler on the Sun Cooling Door 5600 stationary. Use the torque wrench to tighten the collar onto the coupler to the values below.
8. Mark the female and male coupler with an etching tool or other marker for future reference.

9. Repeat Step 6 and Step 7 for the smaller couplers (supply line).
10. Once the supply and return connections are completed, open the return service valves, then open the supply service valves.

Before uninstalling a Sun Cooling Door 5600 with Liebert Flex Pipe from the prefabricated piping mains, close the supply service valve, wait approximately two minutes and then close the return service valve.
Read all instructions before beginning.
1. Close the service valves in the supply line to the Sun Cooling Door 5600 (smaller couplers).
2. Close the service valves in the return lines to the Sun Cooling Door 5600 (larger couplers).
3. Locate and have ready the caps and plugs for both ends of the supply and return couplers.
4. Loosen the female supply couplers from the male supply couplers (smaller couplers). This requires two adjustable wrenches. Refer to FIGURE 3-6.
5. The Sun Cooling Door 5600 side of the female couplers must be held stationary while the collars on the couplers are being loosened. Refer to FIGURE 3-6.

7. Place the protective dust cap and plug back onto both ends of the couplers on the Sun Cooling Door 5600 and the port pipe.
8. Repeat Step 5 through Step 7 for the return couplers (larger couplers).
9. Carefully lay the Liebert XD Flex Pipe aside.
Notice - The Liebert XD Flex Pipe might kink if improperly handled. This can cause permanent damage to the pipe.
