Through Walls or Floors
Refrigeration lines run through walls or floors
must be properly insulated. Avoid running lines
through the refrigeration cases. When this is
done the lines must be adequately insulated—
Armaflex or equivalent.
From Machinery to Solid Object
When mounting lines from machinery to a
solid object allow line freedom for vibration
to prevent metal fatigue.
P-Trap Construction
A P-Trap must be installed at the bottom of all
suction risers to return oil to the compressors.
Reduced Riser
When a reduced riser is necessary, place the
reduction coupling downstream of the P-Trap.
Factory Supplied Stubs
Stub sizes provided from the Manifolds do not
automatically correspond to the line sizes nec-
e s s a r y. It is the installer’s responsibility to
supply reduction couplings.
Protecting Valves and Clamps
When brazing near factory installed clamps or
valves, be sure to protect them with a wet rag
to avoid overheating.
