Installation Manual

SAFETY WARNING

Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of

heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training.

Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury.

When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are

attached to the equipment.

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,

DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC

FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED

FOR INTENDED VOLTAGE.

WARNING

Follow EHS Policies!

Failure to follow instructions below could result in death or serious injury.

• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS)

policies when performing work such as hot work, electrical, fall protection, lockout/tagout,

refrigerant handling, etc. Where local regulations are more stringent than these policies,

those regulations supersede these policies.

• Non-Trane personnel should always follow local regulations.

heaters include a rugged, weatherproof enclosure for reliable outdoor operations. The 50 kW

electric heaters are equipped with lockable caster wheels and handles on each end of the unit to

allow the unit to be maneuvered into position. The 150 kW (F1) electric heaters are equipped with

casters and fork pockets on one side. The 150 kW (F0) electric heater has forklift pockets on two

sides only and lifting rings at the top corners of the unit.

WARNING

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.
