Issue:
Unit is too heavy to lift with the available crane. Need to remove components to reduce overall unit weight before the lift.
Resolution:
We don’t recommend removing components from our chillers when installing due to several reasons.
- This will affect the unit center of gravity and all lifting points will be affected so none of the data in the submittal or IOM for lifting will be valid. There are a lot of risks associated with lifting and rigging on our products and to vary the unit center of gravity by removing components will place all liability on the customer / installing contractor.
- Opening the refrigerant circuit to the atmosphere will cause moisture to become present which will ultimately affect component life expectancy etc.
- RTAF units the evaporator is part of the base frame structure because this is a bolted frame. The unit frame coil structure will not have an appropriate support if the evaporator is removed when lifting the unit.
- Unit disassembly could void chiller warranty.
