Refrigeration Split Installation Procedure
If a given unit is too large to be shipped on
one truck bed, the unit must be split. If the
condenser side of the split is too long, a split
is required in the refrigeration system. Each
side of the split will have isolation valves;
one isolation valve is connected to the
condenser side, while the other is connected
to the evaporator side. Keep these
isolation
valves
closed
until the following assembly
procedure is complete.
Caution
, the refrigeration lines between the
isolation valve and cap at the unit split are
charged with 100 psi of nitrogen.
1.
Relieve the pressure in the refrigeration
split that is charged with nitrogen by
attaching a gauge manifold set and
purging through the hoses.
2.
Next remove the copper caps on each side
by using a pipe cutter at the brazed joint
(Joint A and B).
3.
Then braze the provided copper lines
onto their respective open lines.
4.
After the lines are joined, charge the
newly joined section with 200 psi of dry
nitrogen. Test the charge for an hour.
After one hour and no pressure loss ,
relieve the pressure by removing the
Schrader core. Replace Schrader core
once all pressure is relieved.
5.
Next evacuate out each section of
connection piping from valve to valve to
400 microns. The micron gauge must not
rise above 500 microns after 30 minutes
of wait time.
6.
Finally open the isolation valves. The unit
is shipped with the correct refrigerant
charge.
