Receiving Inspection
After unpacking the terminal, check it for shipping damage. If any ship-
ping damage is found, report it immediately to the delivering carrier.
Store units in a clean dry location and do not stack more than four high.
Caution: Do not use the inlet collar, damper shaft, flow sensor or
air tubing (available on LHK only) as a handle to lift or move as-
sembly. Damage to the unit or controls may result.
Before installation, remove fan packing and all foreign material from the
unit. Check the blower wheel for free rotation.
Floor Supports
The units can be mounted directly on the slab. If isolation from the slab is
necesary, the unit can be placed on a rubber or cork pad.
Access to the motor, blower,and damper assebmly is on the top of
the unit. The access and control enclosure doors are sectioned so
that each door is aligned with a floor panel.
Note: If equipped with pneumatic controls the terminal must be mounted
right side up. It must be level within ±10 degrees of horizontal, both
parallel to the air flow and at the right angle of air flow. The control side
of the terminal is labeled with an arrow indicating UP.
Duct Connections for LHK
Slip each inlet duct over the inlet collar of the terminal. Fasten and seal
the connection by the method prescribed by the job specification.
The diameter of the inlet duct “D” in inches must be equal to the listed
size of the terminal; e.g. a duct that actually measures 8 inches must be
fitted to a size 8 terminal. The inlet collar of the terminal is made 1/8”
smaller than listed size in order to fit inside the duct.
Important: Do not insert duct work inside the inlet collar of the
assembly.
Inlet duct should be installed in accordance with SMACNA guidelines.
Rectangular discharge opening is designed for flanged duct connections.
Fasten and seal by method prescribed in the job specification.
If single-point electronic velocity sensor is used, 3 to 5 inlet duct diam-
eters of straight duct should be provided at the terminal inlet.
Minimum Access
Fan Powered terminals require sufficient clearance to service the fan
blower assembly, low voltage controls and line voltage motor controls or
electric heat section from the top of the unit.
For top access panel removal, 2” minimum vertical clearance above the
unit is recommended, plus sufficient horizontal clearance to slide the ac-
cess panel clear of the top of the unit. Horizontal clearance is dependent
on access panel dimensions as indicated on product submittals.
Low voltage control enclosure doors are “L” shaped to allow access from
the top and sides. For low voltage control enclosure access, a minimum
of 18” clear is recommended. Specific control enclosure location is indi-
cated on product submittals. Panel for low voltage enclosures are remov-
able (not hinged). For line voltage motor controls or electric heat control
access, a minimum of 36” should be provided to allow full opening of
hinged access doors. Specific location is indicated on product submittals.
Important: These recommendations do not preclude NEC or local
codes that may be applicable, which are the responsibility of the
installing contractor.
