ALL-METAL PIERCING TYPE COUPLINGS
Once connected, the All-Metal Piercing Type Couplings on this
system cannot be disconnected without total loss of the
refrigerant charge.
DESIGN ADVANTAGES:
NO LEAKS:
Couplings cannot leak prior to connection because
both halves are sealed shut by brazed all-metal diaphragms.
MIX & MATCH:
Each half of your system is precisely charged with
refrigerant at the factory. After coupling together, the completed
system will have the correct total charge.
RESULT:
Any Adler/Barbour VD-150 series aluminum evaporator,
VD-160 PowerPlate, or VD-170 series blower evaporator can be
connected to any CU-100 ColdMachine™ or CU-200
SuperColdMachine™ condensing unit.
NOTE:
Our 50 Series and 80 Series products each have their own
“families” of charge-balanced evaporators. They are not
interchangeable with each other or with the ColdMachine™
evaporator family. Nor can a 50 Series or 80 Series condensing
unit be used to replace a ColdMachine™ CU-100 or CU-200
condensing unit by coupling it to a ColdMachine™ Series VD-150,
VD-160, VD-170 evaporator.
TOOLS FOR THE ALL-METAL PIERCING TYPE COUPLINGS:
• Use a 5/8” wrench for the male coupling
• Use a 13/16” wrench for the female coupling
• Tighten both couplings to 12–14 ft / lbs.
(16.3 to 19.1 newton/meters)
TOOLS FOR THE TUBE SET CONNECTION TO POWERPLATE:
• Use a 5/8” wrench for the male coupling. Do not loosen the
coupling from its brazed-on base.
• Use a 3/4” wrench for the female coupling. Do not loosen the
coupling from its brazed-on base.
• Tighten both couplings to 12–15 ft / lbs.
(16.3 to 20.3 newton/meters)
BEFORE CONNECTING
Secure tubing and wiring to protect from chafe and vibration.
•
Coil the excess tubing and the thermostat wiring
harness in an 18” to 24” diameter coil and secure
preferably in a horizontal orientation.
• Support the refrigerant tube set and the wire harness using
clamps and/or plastic wire ties (4 supplied).
• Keep the tube set and harness out of bilge water and protected
from chafe and vibration.
• The tubing must not be allowed to vibrate or chafe.
• Seal the exit hole in the icebox wall using the supplied
mastic.

DESIGN & OPERATION
A complete 5780 series coupling consists of the combination of
male and female coupling halves. You have the option of
choosing either coupling half with or without a charging port,
depending on your particular application.
COUPLING HALVES BEFORE CONNECTION
Diaphragms in the coupling halves provide a seal that prevents
refrigerant loss before connection. The male half (right unit)
contains a cutter blade, the metal refrigerant sealing diaphragm
and intermediate synthetic rubber seal which prevents loss of
refrigerant while the coupling is being connected. The female half
(left unit) contains a metal diaphragm, which is leakproof metal
closure.
COUPLING HALVES CONNECTED
Tightening the union nut draws the coupling halves together,
piercing and folding both metal diaphragms back and opening
the fluid passages, thereby providing minimal restriction to flow.
When fully coupled, a parent metal seal forms a permanent
leakproof joint between the two coupling halves preventing the
loss of refrigerant to the atmosphere.
