6.2  Moisture Prevention Measures

6.2.1 

Required Items

This section applies to all TTS/TGS/TTH/TGH compressors.

The following steps are recommended to prevent condensate infiltration and stagnation in the 
electrical connections. Condensation issues may become exaggerated in hot and humid conditions.

Consumables:

•  Lint-free cloth or clean rags 

•  Soft-bristle brush

•  Small wire brush

•  Greaseless lubricant spray 

•  Rust inhibitor spray

•  Dielectric grease (Danfoss LLC part # 901982 or equivalent)

•  Dielectric grease spray

Application of Dielectric Grease

The dielectric grease can be applied by:

•  Finger

•  Small brush

6.2.1.1  Service Side Disassembly

1.  Isolate the compressor power as described in Section "1.8 Electrical Isolation" on page 19 of 

this manual.

2.  Allow time for the compressor to reach ambient temperature.

3.  Remove the Service Side Cover from the compressor. 

4.  Remove the I/O Cable, Serial Driver, BMCC, and PWM from the Backplane Board. Make sure the 

board assemblies do not come in contact with electric or static sources. 

Figure 6-1  Module Removal

NOTE

The Danfoss LLC part # 901982 Dielectric Grease is a natural lanolin-based product which is non-toxic.

• • • DANGER • • •

Be sure to follow the manufacturer’s usage and safety recommendations when using the aforementioned chemicals.
