Refrigeration Piping - Hill Phoenix ONRB Installation & Operation Handbook

REFRIGERATION PIPING

Refrigeration components and the coil
outlet hole are located to provide the best
access for installation and maintenance. As
the diagrams below indicates, the coil outlet
hole is positioned forward on the right hand
side of the case, fully visible in front of the fan
plenum. An optional piping-to-top configura-
tion can be ordered that runs the refrigeration
lines through the top of the case at the location
shown below. Note that on the narrow six
door case an extra support is present on the
end frames that requires case-to-case piping
to be fed through the opening.
