Do not damage the roof during installation. If the roof is of bonded construction, consult a building contractor or architect for special installation requirements. • Use spring isolators to minimize vibration transmission into building structure. YVAM Air-Cooled Centrifugal Liquid Chiller... -
Page 25: Clearance Requirements
When units are installed in an enclosure, the enclosure height must not exceed the height of the unit on more than one side. If the enclosure is of louvered construction, the same requirement of static pressure loss applies as for ducts and attenuators. See Other considerations.

Page 29: Isolators
Isolators Vibration isolation Do not install YVAM chillers without isolation. Vibration isolation is an important option that must be accounted for at chiller installation. If isolators are not ordered, they must be selected based on the loading at the specific chiller locations. Contact a Johnson Controls representative for assistance if isolators are not provided. - Page 30 8. To complete the installation, fine adjust the isolators to level the equipment.

Page 34: Make Piping Connections
During operation, the glycol freezing point must also be below the lowest expected refrigerant temperature. If the YVAM chiller is exposed to subfreezing ambient temperatures at any time during its life, it is critical to protect against evaporator freeze damage. The YVAM chiller can be equipped with features to prevent freeze damage to the evaporator. - Page 35 Table 12: YVAM freeze damage protection requirements Condition Chiller control of chilled fluid...

Page 38: Wiring Connections
The factory mounted VSD does not require wiring to the compressor motor. The motor power wiring is factory connected to the VSD. Refer to the YVAM Unit Wiring and Field Control Modifications Manual (Form 160.88-PW2). All wiring to the control panel is completed by the factory. A control power transformer is factory furnished with the VSD. -
