Units equipped with 20-30kw electric beaters require a l-in cleat'.nee 1o combustiMe materials for the first 36 in of sopply duct,
A. Ductwork Acoustical Treatment
Metal duct systems dlat do not ilave a 90 ° elbew and 10 fi of main duct to first branch t_keo fl" m_y require int elTial acoustical insulaflon lining
As an a]telal_flve, fibreus ductwerk m_y be used if consm_cted and installed in accord;lnce with the latest cdflion ef _MACNA COllStrllcgon
standard on fibreus gl_ss ducts Botil _lcoustical lining and fibrous ductwork shall comply with N_flona] Fire Protection Association as tested by
UL Standard 181 for Class I air duels
PROCEDURE 4--ELECTRICAL CONNECTIONS
All producls from the fectory utilize _1printed-circuit b_md (PCB) which has a low voltage circuit pint.five pose (5 amp), Pan reeler speed tap
selecflon terminal (SPT), _lod time delay relay (TDR) jumpel To disable the TDR feature, sever the jumper wire JWI (See Fig q )
When a Pactory-approved accessory control package h_s been installed, check all Paclory wiring per unit wiring diagram and inspect l_actory wiring
connections to be sine none were loosened in transit or installation. If a difl_rent control package is required, see unit rating plale.
_& CAUTION: If a disconnect switch is to be mounted on unit, select a location where dritl or fastener will not contact
electrical or refrigerant components. Failure to follow this CAUTION could result in minor personal injury or product and
property damage,
IBefore proceeding wflh efect]icM connections, make certain thai supply voltage, frequency, phase, and ampac fly me as specified on the unit ragng
plate. See unit wiring label for proper field high- and few-vol_ge wiring¸ Make all electrical connections in accordance with the NEC aod any
local codes or erdinpa_ces _bat may apply¸ Use copper wire only¸
_e unit must have a sep_trale bmncb electric circuit with a field-soppliod disconnect sw flcb located within sight from and readily accessible from
the unfl
On units with a faclory installed disconnect with pull-out removed, service and maintenance can be safely performed o11 only the load side of the
control package.
_ WARNING: Field wires on the line side of the disconnect found in the fan coil unit remain live, even when the pull-out
is removed. Service and maintenance to incoming wiring can not he performed until the main disconnect switch (remote to
the unit) is turned off. Faiture to do so will result in electrical shock causing personal injury or death,
A. Line Voltage Connections
]f unfl contains _lecessory electric heater, remove and discard power plug from Pall coil _nd connect male plug Prom healer to female plug from
unit wiring harness. (See Elecrdc Heater Installagon festructions )
For units without electric beat:
1. Connect 208/23fly power leads Prom field disconnect 1o yellow and black slripped leads
2. Connect ground wire to unfl ground lug
