VICE ANY UNIT WITHOUT FOL-
LOWING SAFE PRACTICES RE-
GARDING MECHANICAL EQUIP-
MENT.
• All power must be disconnected before any in-
stallation or service should be attempted. More
than one power source may be supplied to a unit.
Power to remote mounted control devices may
not be supplied through the unit. Never wear
bulky or loose tting clothing when working on
any 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
refrigerants or lubricants.
• Never pressurize any equipment beyond specied
operating pressures. Always pressure test with
an inert uid 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.
• Always protect adjacent flammable material
when welding or soldering. Use suitable heat
shield material to contain sparks or drops of
solder. Have re extinguisher available for use
when welding or brazing.
The manufacturer assumes no responsibility for personal
injury or property damage resulting from improper
or unsafe practices during the handling, installation,
service, or operation of any equipment.
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 veried 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 factoryshipping 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 notied immediately
so that the proper action may be instituted. Should
any question arise concerning warranty repairs, the
factory must be notified 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.

FORM ET115.24-NOM1 (519)
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.

INSTALLATION, REFERENCE
ENVIRO-TEC SEISMIC
INSTALLATION DOCUMENT.
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
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.
ENVIRO-TEC
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.

FORM ET115.24-NOM1 (519)
All water coils must be protected from
“H” MUST BE AT LEAST
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 notied 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
specications. 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.
RETURN AIR LOCATION
This unit is equipped with a eld reversible rear or
bottom ducted air return for plenum style units.
To change the return air location, remove the reversible
plenum box panel and the lter rack. Rotate both the
reversible panel and lter rack 180 degrees. Replace
the reversible panel in the old lter rack position and
fasten using the supplied screws. Fasten the lter rack to
the location where the reversible panel was and replace
the lter(s) as described above.
Bottom Return
The drain should always be connected and piped to an
acceptable disposal point. For proper moisture carryoff, 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.

FORM ET115.24-NOM1 (519)
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. Rotate 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.
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 congurations.
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
specications. If not included on the unit or furnished
from the factory, ENVIRO-TEC 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.
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.
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.
ELECTRICAL CONNECTIONS
ELECTRICAL SHOCK HAZARDS.
All power must be disconnected prior
to installation and serving this equip-
ment. More than one source of power
may be present. Disconnect all power
sources to avoid electrocution or shock
injuries.
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
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 modication 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.
Portions of the inlet louver not directly
below unit inlet may require covering in the eld on applications where
inltration 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 specic dimensions.
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.
Fan coils are not intended for temporary heat/cool or
ventilation. Units are not designed or equipped to
operate in dusty construction environments. Operation
of the units in conditions outlined above could result in
damage to the equipment or building and furnishings
and/or void all manufacturer’s warranties.
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.
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 filling, 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.Check to ensure that no leaks
are prevalent at the coils, coil connections, piping
packages, etc.

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
Motor & Fan Data
NOTES:
1. Motor electrical data is nameplate data. Actual data will vary with application.
2. Motors nameplated for 208-230/1/60. Data is at 230 volts.
3. ECM motors operated on 208/1/60 power result in reduced airow.
