Chapter 20.0 Installation
20.1 Unpacking and Inspection
The compressor should be carefully inspected for visible signs of damage. Check for loose bolts and damage to
covers or the outer casing. Damage should first be reported to the carrier, not Danfoss LLC. You can contact Danfoss
LLC Product Support to assist in determining the extent of damage or if the compressor should be returned to
Danfoss LLC. Damage should be specified on the Bill of Lading or transportation/freight forwarder documentation.
Open all containers and verify all parts against the packing list. Report any shortages to Danfoss LLC Customer
Service. Contact Danfoss LLC Customer Service to conduct report actions via the Incident Report form.
20.2 Rigging Requirements
Care must be exercised at all times when rigging or handling the compressor to protect it from damage. Two
eyebolts (one at each end) are provided for compressor rigging. A spreader bar should be used to safely position the
compressor into its final location (refer to Figure 20-1 Rigging Set-up).
20.3 Unit Placement
1. If mounting the compressor with the Danfoss LLC mounting kit, refer to 20.4 Mounting Base; if not,
install four isolation pads in accordance with the footprint dimensions given in Figure 20-2 Mounting
Base (TTS/TGS/TTH/TGH) Series.
2. Mount the compressor onto the isolation pads. Ensure the compressor mounting rails are properly
isolated from the base frame once the attaching hardware is secured; for example, the screw should
not extend from the compressor mounting rails to the base frame Figure 20-3 Incorrect Compressor
Mounting Pad Installation and Figure 20-4 Correct Compressor Mounting Pad Installation.
3. Check that the compressor mounting rails are level ± 5 mm (3/16”) in the lateral and longitudinal
planes.
