Fre-Heater Location
The Fre-Heater should be located inside. If it is necessary to locate the Fre-
Heater outside, it must be under a cover. The Fre-Heater must be
protected from water dripping or spraying, or in any way collecting on the
top surface, as this can result in the failure of the heat exchanger. When
selecting a location for PAC Fre-Heater, the ability of that location to bear
the loaded weight of the Fre-Heater should be a prime consideration. The
loaded weights of all PAC Fre-Heaters are listed in Table 1.
PAC Fre-Heater should be located as near as practical to the refrigeration
unit(s). The Fre-Heater should not be located where cooling tower or
evaporative condenser water will be in continual direct contact with the
exterior surface. Careful planning of the Fre-Heater location and plumbing
can reduce installation costs and save time during installation and on
maintenance in the future.
