SECTION I: GENERAL
This instruction covers the installation of the following coils with fur-
naces or MP / ME / MVC modular air handlers.
The coils have sweat connect fittings. All coils are shipped with a low
psi nitrogen holding charge. See Figures 1.
SECTION II: SAFETY
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.

WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
CAUTION indicated a potentially hazardous situation, which, if not
avoided may result in minor or moderate injury. It is also used to alert
against unsafe practices and hazards involving only property damage.
