SAFETY CONSIDERATIONSInstalling, starting up, and servicing air-conditioning equip-
ment can be hazardous due to system pressures, electricalcomponents, and equipment location.
Only trained, qualified installers and service mechanicsshould install, start up, and service this equipment. Whenworking on the equipment, observe precautions in the literatureand on tags, stickers, and labels attached to the equipment. Fol-low all safety codes. Wear safety glasses and work gloves.
INTRODUCTION
The spring isolation accessory kits consist of 4 cast ironspring-flex mounting isolators. The isolator top and bottomsurfaces have oil resistant elastomeric pads attached. The30XW condensers each have two mounting channels that are10 in. wide and up to 473/8 in. long. One isolator is to bemounted under each channel end through the 7/8 in. clearancehole located at the outer edge of the channel. These isolatorsare NOT intended for seismic duty, but are intended to reducethe vibration and noise levels transmitted from the chiller to thesurrounding environment where the unit is installed.
INSTALLATION
Install the accessory kit as follows:
1. The accessory kit is intended for installation at the ini-tial unit installation. One accessory kit is required perchiller. The contents of the kit and part numberrequired are shown in Table 1. All mounting hardwareis field supplied.
2. The chiller mounting pad/rail surface must be level.The base plates of the isolators must be no more than1/4 in. different in elevation for proper operation. Theentire isolator base plate area must be resting on a flatsurface properly designed for the chiller beinginstalled.
3. Isolators are provided with 5/8 in. wide slots on eachend for bolt mounting to the floor, pad, and/or rails asrequired. Mounting hardware is field supplied. SeeFig. 1 for isolator dimensions.
4. Position isolators according to the condenser channelinformation in Fig. 2-3C.
5. Remove leveling bolt and lockdown nut from top ofeach isolator and save for use later. Install the 30XWchiller onto the top plates of the four isolators, makingsure the channel mounting holes in the chiller are cen-tered over the isolator leveling bolt holes. Reinstall theisolator top bolts and lockdown nuts using a field-supplied 3/4 in. washer between the lockdown nut andchiller mounting channel. Leave lockdown nut loose.
6. All isolators require adjustment so that a 1/4 to 1/2 in.gap is set between the upper and lower mount hous-ings. Use leveling bolt to achieve the gap. Adjust isola-tor bolts in sequence: screw down one complete turnon the bolt of each mounting. Repeat with remaining3 isolator bolts using the same sequence until theproper gap is obtained on all isolators. See Fig. 1.
7. With proper gap obtained on all four isolators, tightenlockdown nut on each isolator to secure the chiller tothe isolators.
