movement.
● Tightly wrap and seal the ports on the smart cooling product and pipe with
tinfoil after cutting the pipe to prevent exposure to air.
● Drag the smart cooling product drainpipe completely out of the smart cooling
product after removing the drainpipe.
● Coil the water
rell hose inside the smart cooling product after removing it to
avoid inuence on the smart cooling product movement.
● Drag the copper pipe that goes inside the smart cooling product completely out
of the smart cooling product after cutting the copper pipe to avoid
inuence on
the smart cooling product movement.
● Ignore the small amount of refrigerant oil that
ows out during refrigerant
