IMPORTANT NOTICES

WARNING:

Read and adhere to the following. Failure to do so may result in severe or fatal injury.

WARRANTY WILL BE VOID

IF INSTRUCTIONS ARE NOT FOLLOWED

INSTALLATION

The installation instructions provide a general guideline for the installation and wiring of the heater.

All applicable codes must be adhered to.

MECHANICAL

Heaters must be installed as follows:

LOCATION

1. The air discharge is not directed at a thermostat.

2. The air discharge is across areas of heat loss, such as windows.

3. If equipment freeze protection is of importance, locate heater as close to equipment as possible.

MOUNTING

1. Heater must be mounted level on a vertical surface using the factory supplied mounting brackets

such that there are no obstructions to impede air inlet or discharge (Figure 1b & 3).

2. The mounting surface must be strong enough to:

a. support the heater’s weight, refer to “Specifications” section,

b. withstand abusive situations such as transportable installations of the heater.

– 3 –

1. Read and comply with all instructions in this manual.

2. Heater is to be used only in atmospheres having an

ignition temperature higher than the heater’s maximum

rated operating temperature, as shown on the heater

data plate. Refer to applicable electrical codes for

additional information.

3. To reduce the risk of fire or explosion, do not install

where the marked operating temperature exceeds the

ignition temperature of the hazardous atmosphere.

4. Heater to be used only in the hazardous locations

indicated on the heater data plate.

5. Heater is for dry, indoor use only. Do not immerse in

water. Do not store or use in areas exposed to rain

or snow.

6. Use supply wires suitable for 90°C (194°F) service.

7. Maximum ambient operating temperature 40°C

(104°F).

8. Heater is to be connected and serviced only by a

qualified electrician experienced with hazardous

location equipment.

9. Heater requires a minimum clearance of 9.5 mm

(3/8”) to all the vertical surfaces and must be mounted

a minimum of 203 mm (8”) off the floor. To ensure

adequate airflow, a minimum clearance of 203 mm

(8”) below and 457 mm (18”) above the heater cabinet

must be maintained.

10. Ensure external field-installed thermostat is suitable for

the application.

11. Installation and wiring of the heater must adhere to all

applicable codes.

12. Before opening any enclosures, disconnect the heater

from the power supply. Lock the switch in the “OFF”

(open) position and/or tag the switch to prevent

unexpected power application.

13. External surfaces get hot and can cause burns with

prolonged contact.

14. Ensure unit is permanently mounted level on a vertical

surface using factory mounting brackets.

15. Heater must be kept clean. When operating in a dirty

environment, regularly clean the finned tubes, top

vents, and keep bottom opening free of obstructions.

Follow the recommended maintenance procedures.

Refer to the “Heater Maintenance Checklist” section for

details.

16. Do not operate the heater in atmosphere corrosive to

steel or aluminum.

17. Use factory approved replacement parts only.

18. Heater should be repaired by qualified personnel only.

19. To reduce the risk of ignition of hazardous

atmospheres, conduit runs must have a conduit

seal connected within 152 mm (6”) of the enclosure.

Conduit seals are not required in factory-installed

conduits.

20. A stopping box, Ex certified for the same potentially

explosive atmospheres as the heater, is required to be

fitted immediately adjacent to the field entry.

21. If there are any questions or concerns regarding the

heater, contact the factory. Refer to the last page of

this manual for details.

22. For heaters that are identified as “suitable for storage

temperatures up to 150°C (302°F) the installer must

ensure that the supply conductors are rated for 150°C

(302°F) and stopping box sealants are rated for 150°C

(302°F).

23. The heater must be allowed to cool down for a period

of 2 minutes after operating before any enclosure

covers can be removed.
