literature, tags. stickers, and labels attached to the equipment, and
any other solely precautions that may apply.
INTRODUCTION
These instructions cover the installation of the Motormaster 11
Controller head pressure control device. Refer to the Installation
section t_r directions. Louvered panels are required for this
installation: see Note 9 in the Installation section of this document
and Tables I and 2 for more information.

DESCRIPTION AND USAGE
The Motormaster II head pressure controller is acycle control
device activated by a temperature sensor mounted on a header tube
of the outdoor coil (see Fig. I/. II is designed to cycle the
outdoor-tan motors to maintain the saturated condensing tempera-
ture within normal operating limits of approximately 130 to 110°F
high. 70 to 50°F low 155M.3°C high. 21 to IO°C low). The
controller maintains working head pressure at low ambient tem-
peratures down to -20:'F when properly installed.
INSTALLATION
1. Disconnect power to unit. h_stall lockout tag,
2. Remove unit access panel.
3. Disconnect outdoor-fan motor (OFM). (See Wiring Sche-
mauc. Fig. 8 or 9)
4. Remove OFM wires from unit control box.
5. Mount Motormaster II Controller on unit. Refer to Fig. 3-6.
The controller must be mounted vertically with the leads at the
bottom. Using the Mounting Template (Fig. 10) as a guide.
drill mounting holes. To ensure electrical ground, insert star
washers (supplied with the controller) under the heads of
mounting screws.
NOTE: Field-supplied conduit must be used between controller
and access panel (or wire into unit entrance).
6. Determine sensor location by referring to Fig. 11-25. Route
sensor wire through bottom ol Motormaster II Controller (Fig.
l.) to sensor It,cation specified. Prior to installation, apply
conductive grease supplied with accessory to contact surface
of sensor.

7. Attach sensor to top half of header tube as shown in Fig. 2.
Installed sensor must be left uninsulated.
8. Power wiring must comply with all local and National
Electrical Code (NEC) and International Electric Code dEC)
requirements. Rel)r to Fig. 8 and 9 for power wiring connec-
tions. Coil up all excess wire and secure. (Yellow and blue
wires, from controller, must run to unit contactor and connect
on the load side.)
•Louvered panels are standard on these units.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations,

9. To prevent wind cross-currents from causing abnormally low
condensing temperatures, louvered panels are required on
some models. See Table I and 2 for models reqmring/not
requiring Iouvered panels.
I0. Reconnect power to the unit.
The Motormasler I1 head pressure controller is equipped with an
alternate operating mode. When this mode is selected, the control-
ler shifts the fan cycle sequence to effectively raise the average
condensing temperature approximately 20°F higher than the stan-
dard operating mode. In this alternate mode, the outdoor fan begins
cycling at higher outdoor ambient temperatures. This mode should
only be used if the evaporator coil shows signs of frosting at low
outdoor ambient temperatures.
To select the alternate operating mode. move the jumper wire on
the Motormaster I1 control board from reset TI to reset T2.
Refer to Fig. 7 for thermistor resistance vs. temperature.
