Connection Location
The refrigerant line connections are at the right-
hand end of case (end opposite the main serial
plate) beneath the display pans. A sticker marks
the location of the connection. The installer must
saw a hole to exit the case.
A refrigeration shroud ships with each case. Be-
fore making connections, place the refrigeration
shroud over refrigeration piping so that when the
shroud is rotated into place, it will be in the
upright position. The Figure 2-1 shows the correct
orientation.
Be careful not to burn, scorch or over-heat the
shroud when making connections.
Once connections have been made, apply silicone
sealant to the bottom of the shroud as shown in
Figure 2-2.
