10. Refrigeration Line Stub-out Connections
(Remote Units)

Remove front panel.

Refrigerant stub-out access opening is usually at
the front on the left hand side of the base (see
illustration at top-right).

Stub-out connections are accessed from inside
the case. Remove interior decks and fan shroud
assembly to access.

Remove foam material (if any) from the entry
hole provided in tub drain trough.

Fill access hole with suitable filler/foam to insure
watertight integrity of tub.

Caution! All suction lines must be insulated
at underside of tub.

Refrigeration line stub-out locations are either at
case rear or side (as shown mid-right).

Sweat the suction line and liquid line
connections.
11. Refrigeration Drain Connection
(Remote Units)

Depending upon drain access needs, either front
or rear panel may be removed to gain access to
drain stub-out.

1.5" male PVC stub-out connection is under the
case on the right hand side.

Drain stub-out may be at case center in
extended length cases.

Connect tub drain to floor drain. Maintain
1/4"-fall per foot to provide proper drainage.

Illustration at top-right may not reflect every
feature or option of your particular case.
12. Condensate Pan / Drain Position
(Self-Contained Units)

Remove the rear panel by lifting up & out.

Slide the refrigeration package out from case.

Condensate pan is now accessible.

Insure that the condensate pan is positioned
under the PVC condensate drain trap.

Caution! Check that condensate pan is
plugged into receptacle inside base. If not,
water may drain onto floor, causing damage!

13. Electrical Wiring Diagram

Each case has its own wiring diagram
folded and in its own packet.

Wiring diagram placement may vary; it may
be placed near condenser fan cover, ballast
box, raceway cover, or other related
location.
14. Ventilation and Clearance

Self-Contained refrigerated cases must
maintain airflow clearance of 6" (minimum) to
12" (recommended) at front and rear.

Restriction of air can void warranty.
