If the valve package connection at the coil is a union, the coil
side of the union must be prevented from twisting ("backed
up") during tightening to prevent damage to the coil tubing.
Do not over tighten the union preventing distorting ("egg
shaping") of the union seal surface and destroying the
union.

INSTALLATION, OPERATION, & MAINTENANCE MANUAL
The supply and return connections are marked on the coil
stub outs and the valve package, with an "S" meaning supply
or inlet and "R" meaning return or outlet indicating fluid flow
direction to and into the coil. Blue letters mark the chilled
water connections and Red letters mark the hot water or
steam connections.
In the case of field-installed valves and piping, install the
chilled water valve cluster (or expansion valve on DX units)
in such a way that any dripping or sweating caused from
condensation is contained in the drain pan or other device
such as an optional extended drain pan or factory drip lip.
Factory drip lips are field installed and may be packaged
separately from the unit. Factory supplied cooling coil valve
packages will be arranged to locate as much of the package
as possible over a standard drip lip. Some field configurations
may require additional insulation be applied to the exposed
water piping to prevent condensation from dripping into
areas not directly above the auxiliary drain pans.
If none of the above factory accessories are provided with
the units, simple flashing may be used to carry moisture into
the unit drain pan.
Field Piping Connections
To chilled water coil: IEC's innovative design incorporates
3/8" copper tubing inside and stubbing out of the coil. To
facilitate ease of connecting to field supplied ½" hydronic
tubing, there is a 3/8" to 1/2" swedge adaptor installed on
both the supply and return water tube connections to the
coil. Care must be taken when soldering the field supplied
tubing to this connection.
The use of solder with a flow or initial melting point below
500°F is recommended to make these connections. Local
codes and/or building specifications should always be
consulted to ensure solder being used is compliant with
current building standards. When making soldering
connections, use a wet rag as a heat sink around the factory
adaptor to prevent overheating of this joint. See Figure 4.
After soldering, use the wet rag to quench the field and
factory connections at this fitting.
