REFRIGERATION
There are three available refrigeration piping options: stan-
dard, rear, and top-piping.
Standard piping penetration is located at the front-right
area of the case, fully visible in front of the fan plenum.
Rear piping penetration is located at the rear-right area,
consisting of a pre-cut access punch-out, exposing the
foam material that must be penetrated prior to pipe join-
ing (Fig. 11). If top piping is utilized, piping stub-outs are
located at the top-back-right of the case.
If hot gas defrost is utilized, suction lines to each case in
the circuit should be of equal distance from the main suc-
tion line. The expansion valve and other controls are locat-
ed on the left-hand side of the case and are accessible by
lifting the two left-hand deck pans—lifting the fan plenum
is not required.
Before operating the case, be certain to remove the ship-
ping blocks (Fig. 12) that protect the refrigeration lines dur-
ing shipping. If it becomes necessary to penetrate the case
tank in any area, be certain to seal any open gaps after-
wards with canned-foam sealant and white RTV.

ATTENTION!
If brazing is necessary, place wet rags
around the area to avoid tank damage.
