SAFETY CONSIDERATIONS
Installation, start-up, and servicing of this equipment
can be hazardous due to system pressures, electrical com
ponents, and equipment location (roofs, elevated struc
tures, etc.)-
Only trained, qualified installers and service technicians
should install, start up, and service this equipment.
When working on this equipment, observe precautions in
the literature and on tags, stickers, and labels attached to
the equipment and any other safety precautions that may
apply.
A WARNING
Open all remote disconnects before servicing this equip
ment. Electrical shock could result in personal injury.
GENERAL
This book contains instructions for the installation,
start-up, and service of the Motormaster III control on
38AKS008-012, 38AQS008, 38AK008-012, 48/50TJ008-
014, 48/50HJ008-014, and 50LJQ008,012 units. The
Motormaster III control is not used on 50-Hz versions of
the 50HJ008-014 and 50LJQ008,012 units.
NOTE: The Motormaster III control is not used on 48/50HJ
and 48/50TJ units with 2 condenser fans. The control is
used on single condensing fan units only.
The Motormaster III accessory is UL (Underwriters’ Lab
oratories) and CSA (Canadian Standards Association)
approved on all split system and small rooftop electric cool
ing and gas heating/electric cooling units.
The Motormaster III device is a motor speed control de
vice which adjusts condenser fan motor speed in response
to declining liquid temperatures. A properly applied Motor-
master III control extends the operating range of air condi
tioning systems and permits operation at lower outdoor am
bient temperatures.
Table 1 shows the ambient temperature in cooling at which
each unit will operate without modification.

* Unit has one step of unloading.
To operate the units below the ambient temperatures in
Table 1, wind baffles and the Motormaster III control pack
age must be added. The Motormaster III control permits
operation of the unit to an ambient temperature of -20 F
(-29 C) for small rooftop units, and 0 F (-18 C) for split
system units.
The Motormaster III regulates the speed of 3-phase fan
motors which are compatible with the control. These
motors are included in the package. See Tables 2 and 3 for
the contents of the Motormaster III accessory packages.
The CAMOTOR3001A00 package contains a motor for
208/230 volt, 60 Hz and 220 volt, 50 Hz applications. The
CAMOTOR3002A00 package contains a motor for 460
and 575 volt, 60 Hz and 400 volt, 50 Hz applications. See
Fig. 1.
