Arrangements
Arrangements
Unlike natural convective
products, the Rittling Fanvector
has an increased air capacity due
to the addition of a tangential
blower that pushes a higher
volume of air across the heat
transfer surface. The benefit of
this technology is that less linear
footage of heating products is
required.
The variety of mounting styles
and the slim line design provide
flexibility to the installing
contractor as well as options for
an aesthetically pleasing solution
for the architect.

Installation
Inspection
Upon receipt of the equipment, carefully check the shipment against
the bill of lading. Make sure all units have been received. Inspect the
packaging of each unit, and inspect each unit for damage. Ensure that
the carrier makes proper notation of any shortages or damage on all
copies of the freight bill and completes a common carrier inspection
report. Concealed damage not discovered during unloading must be
reported to the carrier within 15 days of receipt of shipment. If not
filed within 15 days, the freight company can deny the claim without
recourse.
Storage
Equipment should be stored in its original packaging in a clean,
dry area.
Unit protection
Cover units on the job site with either the original packaging or an
equivalent protective covering. Cap the open ends of pipes stored on
the job site. In areas where painting, plastering, and/or spraying has not
been completed, all due precautions must be taken to avoid physical
damage to the units and contamination by foreign material. Physical
damage and contamination may prevent proper start-up and may result
in costly equipment clean-up.
Examine all pipes, fittings, and valves before installing any of the
system components. Remove any dirt or debris found in or on these
components.
Pre-installation
Before unit start-up, read all manuals and become familiar with the unit
and its operation. Thoroughly check the system before operation.
It is the responsibility of the purchaser to file all
necessary claims with the carrier. Notify your
equipment supplier of all damage within fifteen
(15) days of shipment.

Installation
Preparation
■■
Verify that electrical power is disconnected prior to installation and
service.
■■
Ensure that field plumbing and electrical meets applicable national
and local codes and requirements.
■■
The Rittling Fanvector cabinet has keyhole slots included in the
back panel for use in mounting. Proper wall supports and screws to
support the Rittling Fanvector weight should be used when mounting.
The table below shows model weights for each unit size.

■■
Access to the keyhole slots may require removal of the end panels
and the front cabinet panel. Check if keyhole slots are accessible
through access doors or end panels, and that access is not
obstructed by field barriers.
ŠŠ The end caps are attached by a tongue and groove joint and are
removed by simply pulling them away from the ends of the unit.
ŠŠ The front panel is disassembled by removing the screws in the
front panel and lifting the panel vertically.
■■
Prior to fastening the Rittling Fanvector in place, verify that all wiring
and plumbing is accessible to complete the installation.
■■
Securely fasten unit into place.
Installation

Installation
Plumbing
■■
The Rittling Fanvector is supplied with either opposite end, same end
or recessed floor connections.
ŠŠ Opposite end connections have brass headers with a 3/4" FPT
connection. The headers have a 1/4" FPT hole that can be
plugged or fitted with a vent (by others).
ŠŠ Same end connections are supplied with 1/2" straight copper
tubing. Standard 1/2" female copper fittings (sweat) can be used
for connection purposes (by others).
ŠŠ Recessed floor connections are 3/4" straight copper. Standard
1/2" female copper fittings (sweat) can be used for connection
purposes (by others).
■■
Plumbing access openings are cut into the unit cabinet. Openings
can be used as necessary and determined by field plumbing.
■■
Connect inlet and outlet plumbing per building specifications.
■■
All connections should be leak tested prior to electrical connection
and operation.
Electrical
■■
Remove electrical box connection cover to expose unit wiring.
■■
Connect power and thermostat (if used) to unit per the wiring
diagram on page 9.
■■
Replace electrical box connection cover.
If applicable, front panel and end panels should be re-installed at this
time if they were removed for installation purposes.

Operation
Initial start-up
■■
Verify that all isolation valves are open and control valves (if any) are
wired.
■■
Verify that all air has been removed from the hot water system and
there is no air trapped in the coil.
■■
Verify that voltage is within an acceptable range and that fuses and
breakers are properly sized.
■■
If unit is controlled by a thermostat, verify that the control system is
calling for heat.
■■
Verify that the unit switch is in “off” position.
■■
Turn on line power to unit. Move unit switch to “on” position.
■■
Adjust blower speed to maximum setting.
■■
Verify that blowers are moving air through the discharge louvers (top)
of the unit.
■■
Adjust blower speed to minimum setting.
■■
Verify that blowers are moving air through the discharge louvers (top)
of the unit.
■■
If unit is controlled by a thermostat, verify that the control system is
working by adjusting temperature setting to turn system on and off.
Continued operation
■■
Set unit switch to “on” position.
■■
If unit is controlled by thermostat, set thermostat to desired control
temperature.
■■
Set fan control to desired speed.
■■
Maintain unit according to the instructions listed in the maintenance
section of this document.

Maintenance
Motor blower assembly
■■
The blower motor assembly is assembled with long-life,
maintenance-free bearings. There is no need for lubrication of the
assembly.
■■
Periodic cleaning of the fan and motor can be accomplished best
with a vacuum with a soft brush attachment. Cleaning intervals will
be dependent on operating environment, but is recommended at
lease once a year.
■■
Verify that the power is disconnected prior to cleaning.
Coil
■■
Internal coil maintenance is generally not needed for water systems
that are clean and maintained. If it is known that the water system
contains high levels of dirt or debris, use standard coil cleaning tools
and procedures compatible with copper water lines.
■■
Periodic cleaning of the coil fins can be accomplished best with
a vacuum with a soft brush attachment. Cleaning intervals will be
dependent on operating environment, but is recommended at lease
once a year.
■■
Verify that the power is disconnected prior to cleaning.
Cabinet
■■
Clean with a mild soap and warm water as necessary.
