4.16.4 Connection to Refrigeration System Warning
The boiler, when used in connection with a refrigeration system, must be installed so the chilled
medium is piped in parallel with the boiler with appropriate valves to prevent the chilled medium from
entering the boiler.
The boiler piping system of a hot water boiler connected to heating coils located in air Handling units
where they may be exposed to refrigerated air circulation must be equipped with flow control valves or
other automatic means to prevent gravity circulation of the boiler water during the cooling cycle.
4.17 Optional Air Intake Connection
Install air intake connector as shown in Figure 4-9. Use silicone to lubricate the internal surface of the
seals before assembling. For air intake connection piping use only:
•
10” for MODULEX EXT 1500 2S
•
12” for MODULEX EXT 2300 2S - 3000 2S.
The Air Intake Connector that ships with the unit is for spiral ducts only. For other materials, please
contact AERCO directly.
