WARNING

Risk of electric shock. Can cause injury or death. Disconnect local and remote power supplies before working within. Before proceeding with installation of the XDP, read all instructions, verify that all the parts

are included and check the nameplate to be sure the XDP voltage matches the available utility power.

Follow all applicable codes.

WARNING

Risk of unit falling over. Can cause death, injury or property damage. The XDP is top-heavy. Use extreme caution and care when moving and installing this unit.

NOTE

This document is intended to be be used together with site specific documentation and documentation for other parts of the system (heat rejection devices and cooling modules).

NOTE

Before any action that could cause a disturbance in the XD system’s cooling function is begun, the facility manager MUST be informed. In addition, after the action is taken and the work is finished, the facility manager MUST be informed.

NOTICE

Risk of piping and component rupture. May cause injury or equipment damage. Do not close service valves without following recommended procedures for repair,

maintenance and replacement of components. Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of piping. Install pressure relief valves in field piping that may become isolated by service valves.

Fluorinated Greenhouse Gas Requirements—European Union

Stationary air conditioning, refrigeration, heat pump equipments 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 also requires operators to use 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 during equipment service and maintenance and before disposing of equipment.

Refer to the full regulation for additional details.

1.1 General Product Information

1.1.1 Product/System Description

Liebert’s XDP refrigerant distribution unit is an interface between the building chilled water system and the cooling modules in the Liebert XD system. It is designed to circulate and control refrigerant to the cooling modules that are in the room with heat-producing equipment. The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump(s), control valve, receiver, controls, valves and piping.

The Liebert XDP monitors room conditions and prevents coil condensation by maintaining the refrigerant being pumped to the cooling modules at a temperature above the room’s dew point.

All functions, such as switching pumps (if applicable), controlling refrigerant temperature, etc., are automatic.

The Liebert XDP’s minimum recommended operating load is 20% of system nominal capacity. For example, a Liebert XDP160 60Hz system’s minimum load would be 32 kW. Loading below this value can unfavorably affect system operation. Consult factory for any loading below this recommendation.

The Liebert XDP is rated for 160kW (546,000 BTU/H) of cooling.

Product Description

1.2 Equipment Inspection

When the unit is delivered, inspect all items for visible and concealed damage. Damage should be immediately reported to the carrier and a damage claim filed with a copy sent to Liebert or to your sales representative.

1.3 Equipment Handling

Remove these 2 tie-down brackets

Remove these 4 lag bolts to free deck boards

WARNING

Risk of unit falling over. Can cause injury or death. The Liebert XDP is top-heavy. Use extreme caution and care when moving and installing this

unit.

NOTE

Personnel should be properly trained and certified to move and rig equipment.

1.3.1 Handling With Skid

• Always keep the unit upright, indoors and protected from damage.

• If possible, transport the unit using a forklift truck. Otherwise use a crane with belts or cables. In either case, do NOT press on the top edges of the packaging.

• If using a forklift, make sure the forks (if adjustable) are spread to the widest allowable distance to still fit under the skid.

• When moving the skidded unit with a forklift truck, do not lift the unit any higher than 6" (152mm) off the ground. If circumstances require the unit to be lifted higher than 6" (152mm), great care must be exercised and all by-standing personnel are to be no closer than 20 feet (6m) from the lift point of the unit.

CAUTION

Risk of structural interference. Can cause equipment or building damage. While on the skid, the unit is too tall (83" [2108mm] overall height) to fit through a standard

doorway. Any attempt to move the unit, while skidded, through a standard doorway will cause damage to the unit and to the building.

Product Description

1.3.2 Removal from Skid

Liebert recommends using dual hand trucks or a similar method to remove the Liebert XDP from the skid. This is to ensure that both ends of the unit are firmly secure and to provide a good means of unit mobility.

1. Always keep the unit upright, indoors and protected from possible damage.

2. Remove the exterior packaging. Leave the plastic bag over the Liebert XDP until the unit has been moved to its final location. The bag will protect the painted panels against scuffing.

3. Remove two (2) corner tie-down brackets from one side of the unit, on a non-runner notch side of the pallet. Remove eight (8) lag bolts from two (2) end deck boards on the same end where the tie-down brackets were removed (refer to Figure 2).

4. Remove the two (2) end deck boards from one end of the pallet and the attached, notched section

... and center runner sections from one end of pallet.

5. Place a piano jack with its forks snugly against the bottom of the unit and strap the Liebert XDP securely to the jack (refer to Figure 4).

NOTE

Place a mover’s blanket or other cushioning material between the piano jack and the unit’s side panels.

6. Repeat Steps 2, 4 and 5 for the opposite side of the unit. When these steps have been completed, the Liebert XDP will be supported by two piano jacks, one on either side.

7. Remove all of the remaining lag bolts from one (1) of the pallet’s outside runners (see Figure 5).

Figure 5 Remove remaining lag bolts from one runner

8. Remove the runner from which all lag bolts have been removed (refer to Figure 6).

Slide this runner away from the Liebert XDP

Slide the remaining part of the pallet from under the Liebert XDP so the unit may be moved on the piano jacks.

Figure 6 Remove runner from pallet

9. Using the pallet jacks, raise the secured unit to the highest point that the piano jacks will allow. Once the unit has been raised, slide the remainder of the pallet from under the Liebert XDP (see Figure 7). Lower the Liebert XDP so that its base is approximately 1" (25.4mm) off the ground.

1.3.3 Removing Piano Jacks

Once the unit has been moved to the installation location, Emerson Network Power recommends the following method to remove the piano jacks:

1. Lower the unit as far as the piano jacks will allow.

2. Undo all strapping holding the piano jacks to the unit.

3. Remove all cushioning material used to protect the unit from the straps and the piano jacks.

4. Use a pry bar or other lever to lift one side of the Liebert XDP enough to allow removal of the piano jack.

5. Repeat Step 4 to remove the piano jack on the opposite side.

6. Remove the plastic bag.

1.4 Mechanical Considerations

1.4.1 Positioning the Liebert XDP

Install the Liebert XDP according to the site specific documentation and secure the unit to the floor.

The Liebert XDP can be installed near a wall or another Liebert XDP. However, there must be at least 3 feet (92cm) clearance in front of the Liebert XDP as service access for components in the unit.

For additional technical information, refer to the System Design and Configuration Document for the Liebert XD

www.liebert.com, as well as from your local Emerson Network Power representative.
