Handling and
installation
While all equipment is designed
for durability and fabricated with
heavy gauge materials and may
present a robust appearance,
great care must be taken to
assure that no undue force
is applied to the coil, piping
or other components during
handling. Gloves should be
worn when handling finished,
painted units and should never
be set down on unclean, hard
surfaces. Failure to follow
these instructions may lead to
scratching or gouging of the
finished surface.
Although Zehnder Rittling
does not become involved
with the design and selection
of support methods and/
or components, it should be
recognized that unacceptable
operating characteristics and/
or performance may result from
poorly implemented unit support.
Additionally, proper clearance
must be provided for service and
removal of the equipment.
Make sure that the convector
liners are secured tight to
the mounting surface. Using
fasteners, supplied by others,
attach the liner to wall studs by
penetrating the liner wherever
necessary. Locate the convector
coil in the coil clips located on
each end of liner, making sure to
provide proper pitch down from
the supply end if the convector is
being used in a two pipe steam
system.
Upon installation, make sure that
all sweated connections have
been flushed with system water
to avoid corrosion from left over
flux material.
Once the coil is connected into
the heating system, a standard
pressure leak test should be
conducted as specified by the
engineer.
After completion of the pressure
leak test, install the convector
front onto the convector liner.
Make sure that latching screws
for access doors (if any) are
secured with the door closed. If
the convector is supplied with an
optional damper, open and close
the damper blade, with the knob
damper provided, to make sure
that there is no binding of the
blade during operation.
After mounting the unit, it is
then ready for the water or
steam service connection. At
this time it should be verified
that the proper type of service is
actually provided to the unit. On
those units requiring hot water,
the proper line size and water
temperature should be available
to the unit.
On units with steam heating
coils, the proper line sizing and
routing should be verified. The
maximum steam pressure should
never exceed 50 psig. The drain
piping and steam trap, supplied
by others, should be sized
and routed to allow for proper
condensate flow.
