Preface and Warnings and Cautions

Hazard Identification

Warnings and Cautions appear at appropriate sections throughout this literature. Read these carefully.

￿WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

￿CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

CAUTION

Indicates a situation that may result in equipment or property-damage only accidents.

￿WARNING

Operational Hazards!

Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read the installation, operating and maintenance instructions thoroughly before installing or servicing this equipment.

￿WARNING

Compliance Hazards!

Failure to comply with the general safety information may result in extensive property damage, severe personal injury or death.

￿WARNING

Unit Alterations!

Do not alter the unit heater in any way or damage to the unit and/or severe personal injury or death may occur!

￿WARNING

Voltage Hazard!

Disconnect all power supplies before installing or servicing the heater. If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power. Failure to do so could result in fatal electric shock, or severe personal injury.

￿WARNING

Voltage Hazard!

Do not depend upon a thermostat or other switch as sole means of disconnecting power when installing or servicing heater. Always disconnect power at main circuit breaker as described above. Failure to do so could result in fatal electric shock.

CAUTION

Equipment Damage!

Insure that all power sources conform to the requirements of the unit heater or damage to the unit will result!

Follow installation instructions CAREFULLY to avoid creating unsafe conditions. All external wiring must conform to applicable current local codes, and to the latest edition of the National Electric Code ANSI/NFPA No. 70. In Canada, all external wiring must conform to the Canadian Electric Code, Part 1 CSA Standard C22.1 All wiring should be done and checked by a qualified electrician using copper wire only. All steam and hot water connections should be made and leaktested by a suitably qualified individual, per instructions in this manual. Also follow procedures listed on the “Unit Equipment Start-Up Sheet” located in this manual.

Make certain that the power source conforms to the electrical requirements of the heater.

Special attention must be given to any grounding information pertaining to this heater. To prevent the risk of electrocution, the heater must be securely and adequately grounded. This should be accomplished by connecting a grounded conductor between the service panel and the heater. To ensure a proper ground, the grounding means must be tested by a qualified electrician.

Do not insert fingers or foreign objects into the heater or its air moving device. Do not block or tamper with the heater in any manner while in operation or just

after it has been turned off, as some parts may be hot enough to cause injury.

Note: To meet CSA and OSHA requirements, units mounted below 8 feet (2.4m) from the floor must be equipped with an OSHA fan guard.

It is good practice to have a shutoff switch on the electrical power lines controlling the heater. Whenever a unit is serviced, shut power off to the unit.

Since these units are installed in most instances higher than 8 feet (2.4m), proper type of ladders or scaffolding should be used, as set up by OSHA requirements. It is the owner’s responsibility to provide any scaffolding or other apparatus required to perform emergency service or annual/periodic maintenance to this equipment.

In industrial plants, professional maintenance crews should service this equipment.

All Horizontal Unit Heaters are shipped fully assembled and may be used for steam or hot water applications. Coils are factory tested at 250 psig (1723.5 kg).

All Vertical Unit Heaters are shipped fully assembled and may be used for steam or hot water applications.

Coils are factory tested at 400 psig air under water. Fans are balanced and motors are prelubricated.

Unless otherwise specified, the following conversions may be used for calculating SI unit measurements:

1 foot = 0.305 m

1 inch = 25.4 mm

1 psig = 6.894 kPa

1 pound = 0.453 kg

1 gallon = 3.785 L

1 inch water column = 0.249 kPa

meter/second = FPM ÷ 196.8

liter/second = CFM x 0.472

1000 Btu per hour = 0.293 kW

1000 Btu/Cu. Ft. = 37.5 MJ/m3

1 cubic foot = 0.028 m3
