INSTALLATION INSTRUCTIONS

ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation to know the
product better than the customer. This includes all safety pre­cautions and related items.

Prior to actual installation, thoroughly familiarize yourself with
this Instruction Manual. Pay special attention to all safety warn­ings. Often during installation or repair it is possible to place
yourself in a position which is more hazardous than when the
unit is in operation.

Remember, it is your responsibility to install the product safely
and to know it well enough to be able to instruct a customer in
its safe use.

Safety is a matter of common sense...a matter of thinking be­fore acting. Most dealers have a list of specific good safety
practices...follow them.

The precautions listed in this Installation Manual are intended
as supplemental to existing practices. However, if there is a
direct conflict between existing practices and the content of
this manual, the precautions listed here take precedence.

DESCRIPTION

This single pole double throw thermostat device with adjust­able 0° to 45° temperature range is employed in conjunction
with the room thermostat to control the electric heaters that
have been added to cooling and heat pump products. This kit
includes an Outdoor Thermostat, three wires, mounting bracket,
(3) wire caps, and (2) self-drilling screws.

Note: If the outdoor ambient temperature is below 0° F (-18°
C) with 50% or higher Relative Humidity, an Outdoor Thermo­stat must be installed and set at (0º F) on the dial. Failure to
comply wth this requirement may result in damage to the prod­uct which may not be covered by the manufacturer’s warranty.
See Figures 12 and 15 for wiring connections.

The schematic and the terminal view of this device is shown in
Figure 2:

When used as an outdoor thermostat to control increments of
electric heat, connections will be made to terminals 2 and 1.
As temperature rises above the set point contacts 2 to 1 will
open thus preventing the controlled increment of supplemental
heat from operating. As outdoor temperature falls below the
set point contacts 2 to 1 will close allowing the controlled in­crement of heat to operate. See Figures 10, 11, 13, and 14 for
wiring connections.

Use the wires supplied for Outdoor Thermostat connections. If
the installation is with an All Fuel kit, refer to the Installation
Instructions supplied with the AFE18 All Fuel kit for wiring con­nections.

INSTALLATION

The outdoor thermostat is designed to be installed in the space
allocated in the control box of the cooling and heat pump units.

1. Remove the sheet metal screws securing the unit control
box cover.

2. Install the OT18-60A Outside Thermostat using the sup­plied bracket and self-drilling screws (see Figures 3 through

9.). NOTE: Early split, packaged cooling and heat pump
units, refer to Figures 3 through 6. AS*, D*, GS* and SS*
split cooling and heat pump units, refer to Figures 7 and

8. AP*, GP*, DP* packaged cooling and heat pump unit s,
refer to Figure 9.

3. Wire the thermostat per Figures 10, 11, 12, 13, 14, and

15.

4. Route the capillary away from live terminals to prevent
electrical shorts.

NOTE: Outdoor Thermostat copper capillary will remain
inside of the control box on early models. On AS*, D*,
GS*, SS*, AP*, GP* and DP* models, the capillary will
extend outside the control box.

5. Set installed thermostat(s) to the proper outdoor temper­ature. Insert a screwdriver in slot of thermostat dial (Fig­ure 1). Turn set point indicator as shown in figure to de­sired temperature setting on label (counterclockwise for
WARM, clockwise for COLD).

6. Reinstall the control box cover.
