Clearance

The unit must be placed in an area that allows for adequate 

clearance around the unit. See 

Figure 6

 for clearance 

requirements around the sides of the chiller. Doors and 

removable wall sections can be utilized to meet these clearance 

requirements. There must be a minimum 3-foot clearance above 

the top of the chiller. The U.S. National Electrical Code

®

 (NEC) or 

local codes can require more clearance in and around electrical 

components and must be checked for compliance. 

Mounting

The unit must be mounted on a concrete or steel base. Make 

sure that the floor or structural support is adequate to support the 

full operating weight of the complete unit.
WMT chillers are nearly vibration-free. Consequently, floor 

mounted spring isolators are not usually required. Neoprene 

mounting pads are shipped with each unit. It is recommended 

to continue to use flexible piping connectors to reduce sound 

transmitted into the pipe and to allow for expansion and 

contraction.
It is not necessary to bolt the unit to the mounting slab or 

framework. Should this be required by local codes, 1-1/8 inch 

(1.125 inch, 28.5 mm) mounting holes are provided in the unit 

supports at the four corners. When mounted, the base pad of the 

unit must be level to within ± 1/2 inch (0.5 inch,12.7 mm) across 

the length and width of the unit.

Units with single point power, 575V, and/or the optional 

harmonic filter will require additional panels than shown in 

Figure 7

Lifting Guidance

Daikin Applied equipment is designed to withstand the loads of 

the lifting and rigging process resulting from ASME Standard 

P30.1 - Planning for Load Handling Activities or equivalent. 

Lifting guidance is intended for installations of newly delivered 

equipment. If moving previously installed equipment for re-

location or disposal, consideration should be given to unit 

condition. Equipment should also be drained as unit weight and 

center of gravity values do not reflect the addition of water for 

lifting.

 DANGER

Improper  rigging,  lifting,  or  moving  of  a  unit  can  result  in  unit 

damage, property damage, severe personal injury or death. See 

the as-designed, certified dimensioned drawings included in the 

job submittal for the weights and center of gravity of the unit. If 

the drawings are not available, consult the local Daikin Applied 

sales office for assistance.

Installation is to be performed only by qualified personnel who 

are familiar with local codes and regulations, and experienced 

with this type of equipment. Lifting equipment and mechanisms 

must be determined by the Lifting Director per the current version 

of ASME Standard P30.1 or equivalent and must be suited for the 

load capacity. 

Daikin Applied is not a licensed nor certified rigging specialist. 

Therefore it is the customer’s responsibility to consult a certified 

rigging contractor to rig, lift, and move components and 

subcomponents properly and safely as needed. 

 CAUTION

Forklifts  may  not  be  used  to  lift  or  move  WMT  units  as  the 

method may result in unit damage.

 CAUTION

When around sharp edges, wear appropriate Personal Protective 

Equipment (PPE), such as gloves, protective clothing, foot wear, 

eye protection, etc. to prevent personal injury. 

Lifting Brackets

Lifting bracket designs vary from product to product. Rules of 

engagement with the lifting brackets are the same regardless of 

the bracket type. 
For 

WMT

 units, a typical lifting bracket with 2ʺ (51 mm) diameter 

holes found on the upper corners of each end cap are illustrated 

in 

Figure 2 

. See the as-designed certified drawings for specific 

lifting points on this product model. 
Engagement with each bracket is to be as close to vertical as 

possible. The maximum allowable lift angle from the vertical is 30 

degrees as shown in 

Figure 2

. If the lift angle shifts beyond 30° 

from vertical on any of the lift points, the lift shall not proceed until 

a plan and rigging can be secured that will correct the angle of 

lift. 

 WARNING

The lifting angle must not go beyond 30 degrees from vertical or 

the unit can become unstable which may result in unit damage, 

property damage, severe personal injury, or death.
