General Information

Unit Nameplate

The unit nameplate is located in the left hand end pocket, behind the con- trol box. It includes the unit model number, serial number, electrical char- acteristics, and other pertinent unit da- ta.

Factory Shipment

Before shipment, each unit is leak test- ed, and run tested for proper control operation.

Access

A three panel front access of the unit ventilator allows for speedy set-up during field commissioning. This de- sign allows for the end pocket of the unit ventilator to be open while the fan (airside) section stays closed.

End Pockets

Access for piping and controls is made through the unit ventilator’s end pock- ets.

Coil Connections

The coil headers and drain connec- tions are made within the unit chassis to allow a tight seal and help prevent air leakage around the coil. The con- nection sizes vary dependent upon type of coil combination specified.

Coil Type	Size (in.)
Hydronic Cooling (Main) Coil or	3/4" Nominal
Heating/Cooling Changeover Coil	7/8" I.D.
Heating (Auxiliary) Coil	1/2" Nominal
	5/8" I.D.
Steam Heating Coil	1" FNPT
Direct Expansion Coil	3/8" O.D. Liquid
	7/8" O.D. Suction

Unit Drain Pan

The drain pan is dual-sloped for effec- tive condensate removal. It is made from a non-corrosive material to help eliminate issues associated to leaking or standing water. It may be easily re- moved for cleaning. The drain pan connection size for all Trane VUVE models is 7/8" O.D.

Motor

Motors for the VUVE model do not in- clude an external fan bearing on the end of the fan shaft. This helps avoid issues related to fan bearing mainte-

nance (oiling is not needed), and/or bearing replacement.

Filters

Filter sizing for the unit ventilator are an off-the-shelf design to reduce or help eliminate local stocking of the fil- ters.

Sliding Fan Deck

Convenient access to the fan motor and wheels for maintenance and ser- viceability may be made through Trane’s easy-slide fan deck design.

Outside/Return-Air Dampers

The outside-air/return-air damper is a one piece, linkage free design result- ing in a superior air-tight seal.

Field Installed Controls (Option)

The unit comes equipped with a fan speed switch, damper blade (only), and an optional low temperature de- tection.

End Device Control Package (Option)

Units containing the End Device con- trol design will incorporate a pre- wired, selected control components to a terminal strip for wiring a field pro- vided controller and temperature sen- sor.

Note: for controller operation malfunc- tion of any non-Trane, field installed controls, consult the literature or tech- nical support of the controls manufac- turer.

Tracer™ ZN520 Control Package

(Option)

The ZN520 electronic digital controller is a factory installed, tested and com- missioned LonTalk™ certified design. It may be used in a stand-alone control scheme, or as part of a building auto- mation system. The controller is pre- wired to Trane selected control com- ponents best suited for room comfort.
