Introduction
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal safety and the proper
operation of this machine depend upon the strict observance of these precautions.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTIONsIndicates a potentially hazardous situation which, if not avoided, could result in
minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE Indicates a situation that could result in equipment or property-damage only
accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally
occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the
identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine
and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all
refrigerants containing these compounds have the same potential impact to the environment.
Trane advocates the responsible handling of all refrigerants-including industry replacements for
CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry. All technicians who handle refrigerants must be
certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the
requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the
equipment that is used in these service procedures. In addition, some states or municipalities may
have additional requirements that must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be
performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE
and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field
wiring installation and grounding as described in NEC and your local/state electrical codes.
Failure to follow code could result in death or serious injury.

WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury.
Technicians, in order to protect themselves from potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well
as the instructions below:
• Before installing/servicing this unit, technicians MUST put on all PPE required for the work
being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard
hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS
and OSHA/GHS (Global Harmonized System of Classification and Labeling of Chemicals)
guidelines for information on allowable personal exposure levels, proper respiratory
protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE
in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash
protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING,

Unit Controls
50 kW and 150 kW (F0) Electric Heater
The 50 kW electric heater is a constant volume unit. The 150 kW (F0) electric heater contains a
variable frequency drive (VFD) to control the supply fan. The VFD on the 150 kW (F0) electric heater
is controlled using the potentiometer dial labeled “Fan Speed” located behind the metal door on
the side of the unit. The 50 kW and 150 kW (F0) units are also equipped with an emergency stop
button and a fan switch to provide on-off fan control.
The 50 kW and 150 kW (F0) units are manufactured with internal time delays to protect the system
from overloading the supply power with a large inrush at the same time. The 50 kW and 150 kW
(F0) heaters are supplied with discharge air thermostats. The discharge air thermostat is located
internal to the unit control box directly behind the unit's main thermostat and system ON/OFF
switch. This thermostat prevents the discharge air temperature from exceeding 160°F which
prevents internal damage to the unit. These units also have high limit switches that are designed
to shut the heaters down if the discharge air temperatures exceed 180°F.
Note: At least one section of duct must be connected to the supply or return of the 50 kW electric
heater to prevent the fan breaker from tripping due to excessive fan speed.

150 kW (F1) Electric Heater
The 150kW (F1) electric heaters contain a 3 hp blower with variable speed drive allows for precise
air flow control. The NEMA 4 control panel includes main disconnect, high limit controller and an
industrial three-pole shutdown contactor for each heating circuit. The unit includes an emergency
shutdown button and indicator lamps for Power On, Heat On, Low Air Flow and Over Temperature.
Also included is a process controller with remote setpoint capacity, digital communications and 4-
20 mA analog output.
The 150 kW (F1) heater is a portable assembly capable of operating at either a 75 kW or 150 kW
heating capacity. The fan speed is controlled with a variable frequency drive to change air flow
volume and is adjusted by the “Variable Speed Control” dial. The output temperature is controlled
with Chromalox®Temperature Controller with a thermocouple mounted in the output air stream.
The heater has two modes of operation – LOCAL and REMOTE.
Local operation relies on the thermocouple located in the heater outlet air flow only and connected
to the Chromalox®Temperature Controller. The default temperature setting is 300°F. The
controller will maintain this output air flow temperature. The controller temperature level can be
adjusted to a lower temperature based on the ambient conditions and operator discretion. The
temperature cannot be adjusted higher than 300°F.
Remote operation relies on the thermostat locatedin the remote controller panel, as well as the
thermocouple located on the heater outlet. The heater will produce 300°F outlet temperature. Once
the remote thermostat is satisfied, the heater will cycle to maintain the remote thermostat setting.
The operator can vary both the output temperature setting and fan speed to achieve desired results.
There are two ON/OFF switches on the control panel. The large rotary switch on the left of the
control panel energizes control power. The smaller ON/OFF selector switch starts the heater. There
are three main fault indicators on the front panel. Any of these faults will shut down the heater.
• High Limit Fault – indicates heater element temperature has exceeded 1000°F. Probes are
located in each of the 75 kW heater element assemblies.
• Air Limit Fault – indicates insufficient air flow over the heater elements. Check for obstructions
to inlet air and fouling of the draft tube.
• VFD Fault – indicates internal problem on VFD. Refer to manufacture’s manual for
troubleshooting procedures. (NOTE: Pushing the Emergency Stop Button will shut down the
VFD and indicate VFD FAULT. 480V power must be removed to reset this fault.)
