• Securely fasten all four (4) corners to
the supporting base.
• If not otherwise directed by the structur-
al engineer or local codes, Use a 7/16
inch or 1/2 inch diameter J-bolt. Use a
hexagon nut with a spring washer.
• Include anti-vibration material chosen
by the acoustics engineer.
• Include enough space for refrigerant
piping and electrical wiring when install-
ing through the bottom of the unit.
• Use an H-beam, concrete support,
or other acceptable support structure
designed by a structural engineer.

• When building a base support for the water source unit, ensure that the floor surface / location has
enough strength to support the weight of the unit, enough space for pipes and wiring, and sufficient
slope for proper drainage between the units, the condensate drain connection, and the floor drain.
• Install the water source unit to a base and in a manner approved by the structural engineer to
minimize damage to the unit in the event of an earthquake. Any deficiency in installation may
cause unit to fall, resulting in physical injury or death.
Anchoring the Water Source Unit
General Mounting
Securely attach the water source unit to a concrete pad, base rails, or other mounting platform that is
anchored to the building structure. Avoid placing the unit in a low lying area where water may accumu-
late. Refer to the dimensional drawings for single, dual, and triple frame systems on page 24, page
25, and page 26, and follow the applicable local code for clearance, mounting, anchor, and vibration
attenuation requirements.
