Caution
Secure all dampers when servicing damper, actuator or linkages.
Dampers may activate automatically; disconnect control circuits or
pneumatic control systems to avoid injury.
Protect adjacent flammable materials when brazing. Use flame and
heat protection barriers where needed. Have a fire extinguisher
available and ready for immediate use.
The equipment covered by this manual is available with a variety of
options and accessories. Consult the approved unit submittal, order
acknowledgement and other manuals for details on the options and
accessories provided with the equipment on each project.
Safe practices regarding mechanical equipment must be followed at
all times when handling, installing or servicing any unit.
All power must be disconnected before any installation or service
should be attempted. More than one power source may be supplied
to the unit. Power to remote mounted control devices may not be
supplied through the unit.
Never wear bulky or loose fitting clothing when working with
mechanical equipment. Gloves should only be worn when required
for proper protection from heat or other possible injury. Safety
glasses or goggles should always be worn when drilling, cutting or
working with chemicals such as lubricants
Never pressurize any equipment beyond specified test pressures.
The manufacturer assumes no responsibility for personal injury or
property damage resulting from improper or unsafe practices during

Preface
Nailor Industries fan coils represent an investment, which can, when
installed and operated properly, give long and trouble free service.
Your equipment is initially protected under the manufacturer’s
standard warranty. However, this warranty is provided under the
condition that the steps outlined in this manual for initial inspection,
proper installation, periodic maintenance and everyday operation
of the equipment be followed in detail. This manual should be
fully reviewed in advance of any actual work being done on the
equipment. Should any questions arise, please contact your local
Sales Representative or the factory BEFORE proceeding.
Unpacking and Inspection
All units have been carefully inspected, tested and packaged at
Nailor’s manufacturing facility.
It is the responsibility of the receiving party to inspect the equipment
upon arrival. Any obvious damage to the packaging and/or its
contents should be recorded on the bill of lading and a claim should
be filed with the freight carrier.
After determining the condition of the unit’s exterior, including all
piping, each unit should be carefully removed from the package
and inspected for hidden damage. Any hidden damage should be
recorded and immediately reported to the carrier and a claim filed
as before. Should a claim for shipping damage be filed, the unit, the
shipping package and all packing must be retained for inspection
by the freight carrier. All equipment should be stored in the factory
shipping package until installation.
At the time of receipt, the equipment type and arrangement should
be verified against the order documents. Should any discrepancy be
found the local sales rep should be notified immediately so that the
proper action may be instituted. The factory must be notified about
any questions concerning warranty repairs BEFORE any corrective
action is taken. Should equipment require factory operations a
Return Authorization Number will be issued. Any returns not marked
with an authorization number will be refused. The manufacturer will
not accept claims for expenses not authorized.
Ship Loose Items
Several items are shipped loose for field installation. These items
are shipped loose to offer protection against shipping and job site
damage or by customer request. Refer to packing slip. These items
require the same inspection as the unit.
Handling & Installation
Even though the Nailor hi-rise unit is a sturdily constructed unit
both in appearance and in fact, great care should be taken when
handling it.
Care should be taken to protect the coil, risers, piping, and drain
stub outs during handling. None of the piping should be used as
handles for lifting or moving the unit. Units may also have delicate
internal components that could be damaged by improper handling.
Wherever possible the units should be maintained in an upright
position and handled by the exterior casing. Care should be taken
to prevent impact forces on the unit that may cause internal damage
The units covered in this manual are not suitable for outdoor
installation and should never be used for that purpose. The units
and risers should never be stored or installed where they may be
subjected to a harsh environment such as rain, snow, or extreme
temperatures
Care should be taken to prevent any foreign materials from being
deposited in the risers, the space between the risers and the
insulation, drain pan, heater, or motor and blower wheels of the unit.
To prevent contamination, the units and risers should have some
form of temporary covering placed over them during construction.
When installed the unit should be plumbed in two directions using
the unit frame as a reference. Care should be taken that the internal
components of the unit are not damaged while using bolts or lag
screws to anchor unit to the building.
After unit is mounted, the service connections such as water, drain
and electrical can be made. At this time it should be confirmed that
the proper types of services have been provided to the unit. The
water connections should be checked for line size, temperature,
and location. Electrical service to the unit should be compared to
the unit nameplate to verify compatibility.
The routing, and sizing of all piping, the type and sizing of all
wiring and other electrical components such as circuit breakers,
disconnects switches, etc. should be determined by the individual
job requirements and should not be based on the size or type
connections provided with the equipment. All installations should
be made in compliance with all governing codes and ordinances.
This compliance to all codes is the responsibility of the installing
contractor.
Riser Precautions
WARNING:
Should water, especially run-off water from the
construction site, be allowed to enter the space between the
insulation and the copper or the copper pipe itself, it is possible
that the combination of water and certain chemicals like ammonia,
nitrates or nitrites could cause stress corrosion cracking, which
may cause catastrophic failure of the pipe. For more information on
stress corrosion cracking in copper pipes, "google" stress corrosion
cracking and copper pipe.
Caution should be exercised to protect the risers from damage
and adverse conditions during the construction phase. During
the installation phase of the riser chase at the floor opening, it is
recommended that a guard be constructed and installed around
the opening to prevent foreign material, rain and/or snow from
