Technical installation instructions for Pre-Charged Remote Refrigeration are given on the
following pages. Installation requirements for other remote refrigeration systems may vary. If
additional information is needed, your certified refrigeration mechanic or electrician can call
Master-Bilt at 800-684-8988.
Quick-Couples are pre-charged with the proper refrigerant at the factory.

●
Place a steel or treated-wood spreader on the top of the walk-in
to distribute the load of the coil. The spreader must be at least
twice the width of the coil. The coil must be mounted away
from the edge of the roof a distance equal to the height of the
coil (See Figure #1).
● Uncrate the coil and through-bolt it to the ceiling of the walk-
in with suitable fasteners.
Figure #1 Quick-Couple Remote Refrigeration
● Uncrate the condensing unit and locate near coil. Be sure air movement around the unit is not restricted
so the condensing unit will have a sufficient supply of air to function properly.
NOTE: Install evaporator coil in accordance with the manufacturer's recommendations from
inside wall or obstructions to rear of evaporator.
● Drill holes through the walk-in wall large enough to pass refrigeration lines, electrical line and
drain line.
● Connect liquid and suction lines to the coil and the condensing unit.
● Lubricate rubber seal in male half of coupling with refrigeration oil.
● Thread coupling halves together by hand to ensure proper mating of
threads. Tighten with wrenches until coupling bodies “bottom” or a
definite resistance is felt (See Figure #2.)
Figure #2 Quick-Couple Coupling Detail
● Using a scribe or ink pen, mark a line lengthwise from the coupling hex to the bulkhead. Then tighten
an additional 1/6 to 1/4 turn. The misalignment of the mark will show the degree of tightening for future
reference. This final turn is necessary to ensure that the knife edge metal seal bites into the brass seat of
the coupling halves, forming a leak-proof joint.
● When routing refrigeration lines, special care should be taken not to “kink” the lines and restrict the
flow of refrigerant.
NOTE: Wiring diagrams are located inside the pre-wired electrical panel on
the condensing unit
.
CAUTION
Be sure the electrical supply is sufficient for all electrical loads of the quick-Couple Remote
Refrigeration system.
