Chassis Pre-Installation
See Figures 15-18
1. Check chassis data plate. Verify chassis is correct for
cabinet. Chassis I.D. sticker should match sticker on
cabinet blower housing.
2. Remove compressor cover, check for any shipping or
handling damage. Make repairs or adjustments.
a. Verify refrigerant tubing is free of kinks or dents
and that it does not touch other tubes or unit
parts as it passes over or through. Adjust if
needed and separate with closed cell insulation.
b. Inspect insulation inside compressor enclosure for
rubs from tubing or reversing valve. Adjust tubing
or RV inward if needed. Be careful not to cause
contact somewhere else.
3. Inspect all electrical connections. Connections must
be clean and tight at the terminals.
4. Replace any panels or covers removed for steps 2-4.
The chassis is now ready for installation. Always keep
chassis upright.
