Hard drawn copper tubing should be used where no
appreciable amount of bending around pipes or other
obstructions is necessary. Use long radius ells wherever
possible with one exception. Use short radius ells for traps
in all vertical suction risers. If soft copper must be used,
avoid sharp bends, which may cause a restriction.
Fiberglass insulation and a sealing material such as
permagum should be packed around refrigerant lines where
they penetrate a wall to reduce vibration and to retain some
flexibility.
Support all refrigerant lines at minimum intervals with
suitable hangers, brackets or clamps. Braze all
copper-to-copper joints with Sil-Fos 5 or equivalent brazing
material. Do not use soft solder.
Never braze or solder the liquid and suction lines together.
The complete suction line should be insulated with no less
than 1/2" ARMAFLEX or equivalent. If the liquid and suction
lines are to be taped together for support purposes, they
must be completely insulated from one another.
INSTALLING REFRIGERANT MAINS
The units are evacuated and dehydrated at the factory and
shipped with a holding charge of Refrigerant-22. The suction
and liquid connections are sealed with copper discs. Refer
to the appropriate condensing unit installation instructions for
charging data.
