Fig. 1 — Proposition 65 Warning Label
INTRODUCTION
Carrier fan coil units represent a prudent investment offering
trouble-free operation and long service with proper installation,
operation, and regular maintenance. Your equipment is initially
protected under the manufacturer’s standard warranty; however,
this warranty is provided under the condition that the steps out
-
lined in this manual for initial inspection, proper installation, regu
-
lar periodic maintenance, and everyday operation of the equip
-
ment be followed in detail. This manual should be fully reviewed
in advance before initial installation, start-up, and any mainte
-
nance. Should any questions arise, please contact your local sales
representative or the factory BEFORE proceeding.
This document contains general installation instructions for the
42S unit fan coils. Refer to the unit wiring diagram installed on the
blower housing or specific manufacturer literature for any other
type of factory-mounted controls. The wiring diagram can also be
found using the QR code on the label.
See Fig. 2 for unit clearances and service access. Fig. 3-11 for unit
configurations, dimensions, and pipe connections. Refer to unit
wiring label for all electrical connections; follow NEC (National
Electrical Code) and local codes.
PHYSICAL DATA
Component weight data, shipping weights, and filter data of the
42S units are provided in Table 1.
PRE-INSTALLATION
Unpack and Inspect Units
All units are carefully inspected at the factory throughout the man
-
ufacturing process under a strict detailed quality assurance pro
-
gram, and, where possible, ALL major components and sub-as
-
semblies are carefully tested for proper operation and verified for
full compliance with factory standards. Operational testing of
some customer-furnished components such as electronic control
valves and digital controllers may be a possible exception.
Each unit is carefully packaged for shipment to avoid damage
during normal transit and handling. Equipment should always be
stored in a dry place, and in the proper orientation as marked on
the carton.
All shipments are made FOB (free on board) factory and is the re
-
sponsibility of the receiving party to inspect the equipment upon
arrival. Any obvious damage to the carton and/or its contents
should be recorded on the bill of lading and a claim should be filed
with the freight carrier and Carrier should be advised.
After determining the condition of the carton exterior, carefully re
-
move each unit from the carton and inspect for hidden damage. At
this time, check to make sure that “furnished only” items such as
thermostats, grilles etc. are accounted for whether packaged sepa
-
rately or shipped at a later date. Any hidden damage should be re
-
corded and immediately reported to the carrier and a claim should
be filed. In the event a claim for shipping damage is filed, the unit,
shipping carton, and all packing must be retained for physical in
-
spection by the freight carrier. All equipment should be stored in
the factory shipping carton with internal packing in place 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 representative should be notified immedi
-
ately so that proper action may be taken. Should any questions
arise concerning warranty repairs, the factory must be notified
BEFORE any corrective action is taken. Where local repairs or al
-
terations can be accomplished, the factory must be fully informed
of the extent and expected cost of those repairs before work is be
-
gun. Where factory operations are required, the factory must be
contacted for authorization to return equipment and a Return Au
-
thorization Number will be issued. Unauthorized return shipments
of equipment and shipments not marked with an authorization
number will be refused. In addition, any claims for unauthorized
expenses will not be accepted by the manufacturer.
Unit Protection from Damage
The units covered in this manual are identified by a tag on top of
the unit which shows the floor and riser number for which each
unit is designed. Units should not be installed at locations other
than that marked on the unit identification tag. If no specific detail
is shown on tag for unit location then determine configuration for
the Universal unit based on information within this IOM. Should
any questions arise regarding unit configuration, contact the sales
representative or the factory BEFORE proceeding.
While all equipment is designed and fabricated with sturdy mate
-
rials and may present a rugged appearance, great care must be tak
-
en to assure that no force or pressure be applied to the coil, risers,
CAUTION
When installing this unit, observe precautions in the literature,
labels attached to the equipment, and any other safety precau
-
tions that apply.
Follow all safety codes.
Wear safety glasses and work gloves. Never wear bulky or
loose fitting clothing when working on any mechanical equip
-
ment. Gloves should be worn for proper protection against
heat and other possible injuries. Safety glasses or goggles
should always be worn when drilling, cutting, or working with
chemicals such as refrigerants or lubricants.
Use care in handling and installing this unit.
Never pressurize any equipment beyond specified test pres
-
sures. Always pressure-test with an inert fluid or gas such as
clear water or dry nitrogen to avoid possible damage or injury
in the event of a leak or component failure during testing. Al
-
ways 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.
