FREEZING WEATHER PROTECTION

If hard pipe is used (instead of plastic) for the
chilled water lines, be sure that adequate steps
are taken to prevent these pipes from bursting
when they are subjected to freezing temperatures.

If the Bryant coil used with the absorption unit is
subject to freezing it must be protected. Consult
Bryant distributor for recommended procedure to
follow.
