UNPACKING & INSPECTION

All units are carefully inspected at the factory throughout the manufacturing

process under a strict detailed quality assurance program, and where

possible, all major components and subassemblies are carefully tested

for proper operation and veried to be in full compliance with the factory

manufacturing documents. Customer furnished components such as

control valves, switches and DDC controls are not factory tested.

Each unit is carefully packaged for shipment to avoid damage during

normal transport and handling. The equipment should always be stored in

a dry place in the proper orientation as marked on the carton.

All shipments are made F.O.B. factory and it is the responsibility 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 led with the freight carrier.

After determining the condition of the carton exterior,carefully remove each

unit from the carton and inspect for hidden damage. At this time check

to make sure that “furnished only” items such as switches, thermostats,

etc. are accounted for. Any hidden damage should be recorded and

immediately reported to the carrier and a claim led as before. In the

event a claim for shipping damage is led, the unit, shipping carton, and

all packing must be retained for physical inspection 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

veried against the order documents. Should any discrepancy be found,

the local Sales Representative should be notied immediately so that the

proper action may be instituted. Should any question arise concerning

warranty repairs, the factory must be notied BEFORE any corrective

action is taken. Where local repairs or alterations can be accomplished,

the factory must be fully informed as to the extent and expected cost of

those repairs before work is begun. Where factory operations are required,

the factory must be contacted for authorization to return equipment and

a Return Authorization Number will be issued. Unauthorized return

shipments of equipment and shipments not marked with an authorization

number will be refused. In addition, the manufacturer will not accept any

claims for unauthorized expenses

HANDLING & INSTALLATION

While all equipment is designed for durability and fabricated for sturdy

construction and may present a rugged appearance, great care must be

taken to assure that no force or pressure be applied to the coil, piping

or drain stub-outs during handling. Also, depending on the options and

accessories, some units could contain delicate components that may be

damaged by improper handling. Wherever possible, all units should be

maintained in an upright position and handled by the chassis as close as

possible to the mounting point locations.

In the case of a full cabinet unit, the unit must obviously be handled by the

exterior casing. This is acceptable providing the unit is again maintained

in an upright position and no impact forces are applied that may damage

internal components, access panels, or painted surfaces. The equipment

covered in this manual IS NOT suitable for outdoor installations or

hazardous/explosive environments. The equipment should never be

stored or installed where it may be subjected to a hostile environment

such as rain, snow, extreme temperatures or corrosive or chemical laden

atmospheres.

During and after installation, special care must be taken to prevent foreign

material such as paint, plaster, and drywall dust from being deposited

in the drain pan or on the motor or blower wheels. Failure to do so may

have serious adverse effects on unit operation and in the case of the

motor and blower assembly, may result in immediate or premature failure.

All manufacturers’ warranties are void if foreign material is allowed to be

deposited on the motor or blower wheels of any unit. Some units and/

or job conditions may require some form of temporary covering during

construction.

While the manufacturer does not become involved in the design and

selection of support methods and components, it should be noted that

unacceptable system operating characteristics and/or performance might

result from improper or inadequate unit structural support. In addition,

adequate clearance must be provided for service and removal of the

equipment and its accessory components. Anchoring the equipment

in place is accomplished by using the mounting points provided and

positioning the unit to maintain the unit on a LEVEL plane. All units are

supplied with hanging holes for use with all thread rods.

DRAIN PAN

The optional sloped, insulated drain pan can be equipped with a secondary

drain connection. Standard drain pans are externally insulated, single wall

galvanized steel. The drain pan is easily removable for cleaning. The pan

can be turned around 180 degrees for drainage on the opposite side of

the valve package(s) while capturing condensate from both the coil and

the valve package(s). The optional auxiliary drip pan to catch condensed

moisture from valves and piping is easily attachable to the drain pan. The

drain pan is equipped with external slots and is to be sloped toward the

outlet connection prior to start-up. Care must be taken to insure that the

unit drain pan does not slope away from the outlet connection.

AUXILIARY DRAIN PANS

The auxiliary drain pan mounts directly to the unit drain pan using (2) #10

x 1/2” screws.

After the connections are completed, the system should then be tested for

leaks. Since some components are not designed to hold pressure with a

gas, hydronic systems should be tested with water.

RAH-IOM www.superiorrex.com

New Fan Coils – IOM

SO TOUGH,

WE GUARANTEE IT.

caution

All water coils must be protected from freezing after initial

lling with water. Even if the system is drained, unit coils

may still hold enough water to cause damage when exposed

to temperatures below freezing.

Refrigerant systems should be tested with dry nitrogen rather than air

to prevent the introduction of moisture into the system. In the event that

leaking or defective components are discovered, the Sales Representative

must be notied BEFORE any repairs are attempted. All leaks should be

repaired before proceeding with the installation.

After system integrity has been established the piping should be insulated

in accordance with the project specications. ALL chilled water piping and

valves or refrigerant suction piping not located over drain pans must be

insulated to prevent damage from sweating. This includes factory and

eld piping inside the unit cabinet.

The drain should always be connected and piped to an acceptable disposal

point. For proper moisture carry-off, the drain piping should be sloped

away from the unit at least 1/8” per foot. A drain trap may be required by

local codes and it is strongly recommended for odor containment.

PLENUM BOX REMOVAL

In most cases this unit is fully serviceable without the need for removal of

the plenum box. However should the need arise, the plenum box is easily

removable by removing the screws attaching the plenum box to the sides,

top and rear of the coil casing.

COIL HANDING

This unit features a eld reversible coil assembly should the need arise

upon installation to change the handing of the coil. To change the coil

handing, remove the plenum box (if applicable) from the coil by removing

all screws to the coil casing. Next, remove the fan(s), fan deck, and top

and bottom casings from the coil. Replace the bottom coil casing in the

top coil casing position and the top coil casing in the bottom coil casing

position and reattach the fan deck, fan(s) and plenum box (if applicable)

in the original locations.

note

The leaving air side of the n pack will remain the same

after changing the coil handing.

COILS

All fan coils are available in 2 or 4 pipe congurations. Heating and

cooling coils are eld reversible for right or left side connections. On units

with water coils, the maximum water pressure applied to the unit should

never exceed 300 PSIG at 200°F. On units with steam heating coils, the

maximum steam pressure applied to the unit should never exceed 15

PSIG. The drain piping and steam trap should be sized and routed to

allow for proper condensate ow. (Minimum ambient temperature 35°F.

Coils may freeze.)

PIPING CONNECTIONS

Toxic residues and loose particles resulting from manufacturing and eld

piping techniques such as joint compounds, soldering ux, and metal

shavings may be present in the unit and the piping system. Special

consideration must be given to system cleanliness when connecting to

solar,domestic or potable water systems.

Submittals and Product Catalogs detailing unit operation, controls, and

connections should be thoroughly reviewed BEFORE beginning the

connection of the various cooling and/or heating mediums to the unit.

All accessory valve packages should be installed as required, and all

valves should be checked for proper operation. If coil and valve package

connections are to be made with “sweat” or solder joint, care should be

taken to assure that no components in the valve package are subjected

to a high temperature which may damage seals or other materials. Many

two-position electric control valves, depending on valve operation, are

provided with a manual-opening lever. This lever should be placed in the

“open” position during all soldering or brazing operations. Valve bodies

should be wrapped with a wet rag to help dissipate heat encountered

during brazing. Use a brazing alloy to make connections such as BCup- 2.

Soft solder is not recommended.

If the valve package connection at the coil is made with a union, the coil

side of the union must be prevented from twisting (“backed up”) during

tightening to prevent damage to the coil tubing. Over-tightening must be

avoided to prevent distorting the union seal surface and destroying the

union. In the case of eld installed valves and piping, the chilled water

valve cluster (or expansion valve on DX units) should be installed in such

a way that any dripping or sweating is contained in the auxiliary drain pan

or other device. Valves and TXV’s should be secured or supported to

avoid damage to coil headers or distributor tubes.

DUCTWORK CONNECTIONS

All ductwork and/or supply and return grilles should be installed in

accordance with the project plans and specications. If not included on

the unit or furnished from the factory, Superior Rex supply and return

grilles are available in a variety of types.

All units must be installed in non-combustible areas. Some models

are designed to be connected to ductwork with a MINIMUM amount of

external static pressure. Consult the approved submittals and the product

catalog for unit external static pressure limitations.

Units provided with outside air for ventilation should have some form of

low temperature protection to prevent coil freeze-up. Outside air should

be pretreated for best results.

It should be noted that none of these methods would adequately protect

a coil in the event of power failure. The safest method of freeze protection

is to use glycol in the proper percent solution for the coldest expected air

temperature. Consult glycol supplier literature for correct solution ratios.

RAH-IOM www.superiorrex.com

SO TOUGH,

WE GUARANTEE IT.

The manufacturer assumes no responsibility for undesirable system

operation due to improper design, equipment or component selection, and/

or installation of ductwork, grilles, and other eld supplied components.

ELECTRICAL CONNECTIONS

The electrical service to the unit should be compared to the unit nameplate

to verify compatibility. The routing and sizing of all conduit, and the type

and sizing of all wiring and other electrical components such as circuit

breakers, disconnect switches, etc. should be determined by the individual

job requirements and should not be based on the size and/or type of

connection provided on the equipment. All installations should be made in

compliance with all governing codes and ordinances. Compliance with all

codes is the responsibility of the installing contractor. The unit nameplate

lists the unit electrical characteristics such as the required supply voltage,

fan and heater amperage and required circuit ampacities. The unit-wiring

diagram shows all unit and eld wiring. Since each project is different and

each unit on a project may be different, the installer must be familiar with the

wiring diagram and nameplate on the unit BEFORE beginning any wiring.

This unit is not acceptable for installation in hazardous/explosive areas.

CONTROL ENCLOSURE

The optional electrical control enclosure provides access to the electrical

compartment. This compartment houses all electric heat and control

components. Terminal strips are furnished for simple power and control

wiring connections. Multiple knockouts allow wiring entries from either

side of the compartment.

All components furnished for eld installation, by either the factory or the

controls contractor should be located and checked for proper function

and compatibility. All internal components should be checked for shipping

damage and all electrical connections should be tightened to minimize

problems during start-up.

Any devices such as fan switches or thermostats that have been furnished

from the factory for eld installation must be wired in strict accordance with

the applicable wiring diagrams. Failure to do so could result in personal

injury or damage to components and will void all manufacturers’ warranties.

The fan motor(s) should never be controlled by any wiring or device

other than the factory furnished switch or thermostat/switch combination,

without factory authorization.

All eld wiring should be done in accordance with governing codes

and ordinances. Any modication of the unit wiring without factory

authorization will result in voiding of all factory warranties and will nullify

any agency listings.

The manufacturer assumes no responsibility for any damages and/or

injuries resulting from improperly eld installed or wired components.

TELESCOPING BOTTOM PANEL

The telescoping bottom panel allows for fully recessing the unit while

permitting service access into the ceiling plenum. The architectural ceiling

panel is nished with a durable powder coat paint.

note

Portions of the inlet louver not directly below unit inlet may

require covering in the eld on applications where inltration

of ceiling plenum air into space is undesired. Telescoping

skirt and collar assembly must be eld adjusted to assure a

proper t between lter frame and louvered inlet panel

assembly. Refer to assembly submittal drawings for specic

dimensions.

START-UP

Before beginning any start-up operation, the startup personnel should

familiarize themselves with the unit, options and accessories, and control

sequence to understand the proper system operation.All personnel should

have a good working knowledge of general start-up procedures and have

the appropriate start-up and balancing guides available for consultation.

The initial step in any startup operation should be a nal visual inspection.

All equipment, plenums, duct-work, and piping should be inspected to

verify that all systems are complete and properly installed and mounted,

and that no debris or foreign articles such as paper or drink cans are left in

the units or other areas. Each unit should be checked for loose wires, free

blower wheel operation, and loose or missing access panels or doors.

Except as required during start-up and balancing operations, no fan coil

units should be operated without all the proper ductwork attached, supply

and return grilles in place, and all access doors and panels in place and

secure. A clean lter of the proper size and type must also be installed.

Failure to do so could result in damage to the equipment or building and

furnishings, and/or void all manufacturers’ warranties.

COOLING/HEATING SYSTEM

Prior to the water system start-up and balancing, the chilled/hot water

systems should be ushed to clean out dirt and debris, which may have

collected in the piping during construction. During this procedure,all unit

service valves must be in the closed position. This prevents foreign matter

from entering the unit and clogging the valves and metering devices.

Strainers should be installed in the piping mains to prevent this material

from entering the units during normal operation.

During system lling, air venting from the unit is accomplished by the use

of the standard manual or optional automatic, air vent tting installed on

the coil. In the case of the manual air vent tting, the screw should be

turned counterclockwise no more than 1-½ turns to operate the air vent.

Automatic air vents may be unscrewed one turn counterclockwise to

speed initial venting but should be screwed in for automatic venting after

start-up operations.

note

The air vent provided on the unit is not intended to replace the main system air vents and may not release air trapped in other parts of

the system. Inspect the entire system for potential air traps and vent those areas as required, independently. In addition, some systems

may require repeated venting over a period of time to properly eliminate air from the system
