WARNING Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage.

Unit Placement

Units may be placed into a field sup- plied mechanical rack (See Figure 2), or placed on a finished floor. Loosen compressor bolts to release tension of the rubber grommets to help reduce vibration during operation. Sound proofing material (field supplied) is recommended to help attenuate noise generated by compressor vibration.

It is important to leave appropriate clearances around the unit to achieve

maintenance and serviceability to the equipment. See page 6 for service clearance dimensions.

Water Connection

Connect the source-side and load-side water-in/water-out from the water-to- water heat pump to the source system and the load system.

Note: The source for a water-to-water heat pump is typically a boiler/cooling tower or geothermal loop.

The load for a water-to-water heat pump is typically fresh-air unit(s), fan coil(s), hydronic coil(s), radiant heat, wall fin, or potable water.

The source and load connections for the 2-ton through 6-ton equipment is on the right hand side of the unit.

The 20-ton equipment incorporates the source-side connection at the unit’s front, and the load-side connec- tion at the unit’s back.

For vibration isolation, it is recom- mended that flexible steel braided hoses be installed instead of hard pip- ing the equipment to the main loop system or mechanical device.

Trane offers 4-types of hose kit varia- tions:

•Stainless steel braided flexible hose with manual shut-off (ball) valves

•Stainless steel braided flexible hose with manual deluxe shut-off (ball) valves

•Stainless steel braided flexible hose with manual circuit-setter valve

•Stainless steel braided flexible hose with automatic balancing valve

Additional accessories, such as a strainer are recommended for use to eliminate contaminants from entering the brazed-plate or co-axial water-to- refrigerant heat exchangers.
