Chassis Pre-Installation
1. Check chassis data plate. Verify chassis is correct for
cabinet. Chassis I.D. sticker should match sticker on
cabinet blower housing.
2. 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 hit
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.
