Safety considerations
General information
This installation and start-up
instructions literature is for Vertical
Hi-Stack Fan Coil units. Fan coils
are hydronic terminal units designed
for year-round cooling or cooling/
heating. Your equipment is initially
protected under the Zehnder Rittling
standard 2-year warranty provided
the steps outlined in this manual
for initial inspection, installation,
periodic maintenance and normal
every day operation of the equipment
are followed. This manual should
be thoroughly reviewed prior to the
installation, start-up or maintenance
of the equipment. If any questions
arise, please contact your local
Zehnder Rittling sales representative
or the factory before proceeding any
further.
There are a multitude of options
and accessories available with the
equipment covered in this manual.
For more specific details on the
included options and accessories,
refer to the order acknowledgment,
approved submittals and catalogs.
All fastening devices must be
designed to mechanically hold
the assembly in place without
the ability to loosen or break
away due to system operation or
vibration.
All power must be disconnected
and locked out before any
installation or service is
performed to avoid electrocution
or shock. More than one power
source may be supplied to a unit.
Power to remote mounted units
may not be supplied through the
unit.
Electric resistance heating
elements must be disconnected
prior to servicing to avoid burns.
Never use bulky or loose fitting
clothing when working on any
mechanical equipment. Gloves
should always be worn for
protection against heat, sharp
edges and all other possible
hazards. Safety glasses should
always be worn, especially when
drilling, cutting or working with
chemicals.
Never pressurize equipment
beyond specified pressures
as shown on unit rating plate.
Always pressure test with an
inert fluid such as water or
dry nitrogen to avoid possible
damage or injury in the event of a
leak or component failure during
testing.
Always protect adjacent
flammable material when welding
or soldering. Use a suitable heat
shield material to contain sparks
or drops of solder. Have a fire
extinguisher readily available.
The installation of Vertical
Hi-Stack Fan Coil units and all
associated components, parts
and accessories which make
up the installation, shall be in
accordance with the regulations
of all authorities having
jurisdiction and must conform to
all applicable codes. Only trained
and qualified service personnel
using good judgment and safe
practices should install, repair
and/or service air conditioning
equipment.
Untrained personnel can perform
basic maintenance functions
such as cleaning coils and
cleaning or replacing filters.
All other operations should be
performed by trained service
personnel. When working on air
conditioning equipment, observe
precautions in the literature,
tags and labels attached to the
equipment and all other safety
precautions that may apply.
Improper installation, adjustment,
alteration, service, maintenance,
or use can cause explosion,
fire, electrical shock or other
hazardous conditions which
may cause serious personal
injury and/or property damage.
Consult a qualified installer,
service agency, or your sales
representative for information or
assistance.
The equipment must always be
properly supported by rigging and
lifting equipment. Any temporary
supports used during installation
or maintenance must be designed
to adequately hold the equipment
in place until equipment is
permanently fastened and set
in its final location. All supports
must meet applicable local codes
and ordinances.
