1.4.2Placing the Liebert XDC on a Floor Stand

! WARNING

Risk of top-heavy unit falling over. Improper handling can cause equipment damage, injury or death.

Read all of the following instructions before attempting to move, lift, remove packaging from or preparing unit for installation.

! CAUTION

Only properly trained and qualified personnel wearing appropriate safety headgear, gloves, shoes and glasses should attempt to move, lift, remove packaging from or prepare unit for installation.

The water/glycol floor stand can be located beneath the XDC unit or can be installed nearby.

NOTE

Consult the factory if the XDC is not installed on the water/glycol condenser floor stand to prevent exceeding maximum the piping distances.

Refer to the floor stand installation sheet shipped inside the water regulating valve package.

1.Move the floor stand assembly to its installation area and uncrate the unit.

2.Position the floor stand in its final location.

3.Insert leveler pads into each floor stand leg.

4.Level the top of the floor stand to the specified height with the flanged adjusting nut.

5.Tighten jam nuts on all legs against flanged adjusting nuts.

6.Using an appropriate lifting device or method, raise the Liebert XDC and move it above the floor stand.

7.Align the welded tabs on top of the floor stand with the inside of the unit frame base (see Detail A in Figure 7).

8.Maintaining the alignment of the Liebert XDC and the floor stand, lower the Liebert XDC onto the floor stand.

9.Connect the hot gas refrigerant lines from the Liebert XDC to the floor stand with 1-3/8" tubing (see Figures 7 and 8).

10.Connect the liquid refrigerant lines as shown from the Liebert XDC unit to the floor stand with 7/8" tubing (see Figures 7 and 8).

11.Connect the water lines as shown with the provided valving (see Figures 7 and 8).

12.Connect capillary lines from each water regulating valve to condensers in the floor stand (see Figures 7 and 8).

Capillary length is limited to 48" (1219mm).

13.Check the pipes for leaks and evacuate air from all pipes.

14.Insulate all water/glycol lines.

15.Charge each condenser loop with R-407c (see Table 17).
