NOTES: Minimum/maximum limits are only for start-up
conditions, and are meant for bringing the space up to
occupancy temperature. Units are not designed to operate
at the minimum/maximum conditions on a regular basis. The
operating limits are dependant upon three primary factors: 1)
entering source temperature, 2) entering load temperature,
and 3) flow rate (gpm). When any of the factors are at the
minimum or maximum levels, the other two factors must be at
the normal level for proper and reliable unit operation. Consult
the Capacity Tables for each model to determine allowable
normal operating conditions. Units are not designed for
outdoor installation.
