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.
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.
Receiving Inspection
After unpacking the fan coil unit, check it for shipping damage. If
any shipping damage is found, report it immediately to the delivering
carrier. Store units in a clean, dry location.
CAUTION:
Do not use copper coil connections, drain pan
connections, outside air inlet collar, damper shaft, airflow sensor,
electrical conduit, or valve packages as a handle to lift or move
assembly. Damage to the fan coil unit or controls may result.
Ship Loose Items
Items may often be 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.
Minimum Access
Make appropriate accommodations for access panel removal. The
35FH units have access panels on the top, bottom and sides. Some
access may be limited depending on options. The 37FH units have
top and bottom access panels. Electrical enclosures have access
panels that are equipped with hinges. Blowers, motors, coils and
drain pans can be accessed and inspected from the bottom access
panel. For clearances for full opening of hinged access doors, refer
to project specifications, submittal sheets and NEC.
IMPORTANT:
These recommendations do not preclude NEC or
local codes that may be in effect, which are the responsibility of the
installing contractor.
For units including valve package enclosures ensure that the access
door to the valve package is not obstructed. Optional universal filter
