The boiler, when used in connection with a refrigeration
system, must be installed so that the chilled medium is
piped in parallel to the boiler and with appropriate valves
to prevent the chilled medium from entering the boiler.
The boiler piping system of a hot water heating boiler is
connected to the heating coils located in the air handling
units. The boiler piping system may be exposed to
refrigerated air circulation and must be equipped with
flow control valves or other automatic means to prevent
gravity circulation of the boiler water during the cooling
cycle.
Check the installation instructions of the chiller
manufacturer carefully for additional requirements.
Cooling season starts: Close valve V1 and open valve V2.
Heating season starts: Close valve V2 and open valve V1.
Metal tags labelling these valves should be attached.
IMPORTANT
In the above system, the circulating pump must be
operated from a separate on/off switch - not from the
boiler control.
