Mechanical Specifications
fan/valve operation to ensure safe operation and to ensure that two modes of heat are not
operating simultaneously. A transformer is supplied on any voltage unit, eliminating the need for
field installation of a step-down transformer. Unit-mounted quiet magnetic relays are supplied on
all voltages. A high temperature cutout with automatic reset is provided as an integral part of the
elements to de-energize the electric heat in the event of a malfunction.
Filters
Filters are concealed from sight and easily removable. Filters are located behind an integral access
door on horizontal type units. Filters are either 1” throwaway or 1” MERV 8.
Units equipped with 1” MERV 8 filters have a rating based on ASHRAE Standard 52.2. The average
dust spot efficiency is no less than 35 to 40 percent when tested in accordance with ASHRAE 52.1
atmospheric dust spot method.
Units equipped with 1” MERV 13 filters have a rating based on ASHRAE Standard 52.2. The
average dust spot efficiency is no less than 90 percent efficiency on 1–3 micron particles and
greater than 90 percent efficiency on 3–10 micron particles when tested in accordance with
ASHRAE Test Standard 52.2.
Fresh Air Damper
A fresh air opening with a damper is a factory-installed option. Dampers are constructed of 18-gage
steel. Fresh air is sealed off with gasket material when the damper is set in the closed position.
Return and fresh air mixes when the damper is open.
Manual Damper
The manual damper is field-adjustable to allow a zero to 100 percent fresh air position.
Auto Two-Position Damper
The auto two-position damper is factory set at 25 percent when open. The damper can be set in the
field to allow a zero to 50 percent fresh air position.
Economizer Damper
The economizer damper is accompanied by a factory-installed and wired modulating actuator. The
damper is factory set at 25 percent default minimum and 100 percent maximum opening. The
damper is field adjustable using Tracer Summit or Rover to allow a zero to 100 percent fresh air.
Disconnect Switch
A unit mounted disconnect switch is available as a standard option on all units.
Colors
Six decorator colors are available in a baked powder finish. For a color chart, contact your local
Trane office for a copy of UNT-SLB017-EN (Color Selector: Cabinet Heaters, Fan-Coils, Unit
Ventilators, & Water-Source Heat Pump Consoles).
Extended End Pockets
On vertical or horizontal cabinet units, an 8” extended end pocket is available on the piping end.
Tamperproof Locks
Key-operated locking access doors and/or panels will help prevent nuisance tampering with unit
and/or controls. Tamper proof locks are available on vertical cabinet, horizontal cabinet, vertical
recessed, vertical slope top, and low vertical units.
