Cooling/Heating Pipe Connections
CAUTION: Residues and loose particles
resulting from manufacturing and field piping
techniques such as joint compounds, soldering flux, and
metal shavings may be present in the unit and the piping
system. Give special consideration to system cleanliness
when connecting to solar, domestic or potable water
systems.
Thoroughly review submittals and product literature
detailing unit operation, controls, and connections BEFORE
beginning the connection of the various cooling and/or
heating mediums to the unit.
All accessory valve packages shall be installed as required,

valve packages may be shipped loose with the equipment.
In these cases, perform a dry fit of the assemblies to ensure
proper alignment and access to the assembly components
can be utilized for maintenance and service.
If coil and valve package connections are made with a
"sweat" or solder joint, verify that no components in the
valve package are subjected to a high temperature which
may damage seals or other materials. Do not allow valve
bodies to exceed 300°F. Protect all valve and water control
assemblies with wet or damp rag wrapped around the body
during the soldering/brazing process.
Many two position electric control valves, depending on
valve operation, are provided with a manual opening lever.
Place this lever in the "open" position during all soldering or
brazing operations.
