INSTALLATION
General Mounting / 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 accumulate. Refer to dimensional drawing in the "Product Data" section on page
10, and follow the applicable local code for clearance, mounting, anchor, and vibration attenuation requirements.
• 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, and enough space for pipes and wiring.
• 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.

• Securely fasten all four (4) corners to the
supporting base.
• If not otherwise directed by the structural
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 installing through
the bottom of the unit.
• Use an H-beam, concrete support, or other
acceptable support structure designed by a
structural engineer.
