Installation Guide

REFLECTOR PANEL HEATER INSTALLATION GUIDE Issue 5 May 2007 2104M0728

1 Introduction

The Reflector Panel Heater is designed to be used with the Searchline Excel Cross Duct

infrared gas detector (see manual 2104M0511 for further details of this system). The

Reflector Heater Panel replaces the standard double glazed retro-reflector in applications

where there is risk of condensation occurring on the retro-reflector. The Reflector Heater

Panel is available in two sizes: short range (part number 2104B0715) and long range (part

number 2104B0716).

2 Safety

Ensure that you read and understand these instructions BEFORE handling or operating the

equipment.

Please pay particular attention to the Safety Warnings.

WARNINGS

The Reflector Panel Heater is certified for and intended for use in potentially hazardous areas.

Install and use the Reflector Panel Heater in accordance with the latest regulations.

For installations in the UK, the code of practice SELECTION, INSTALLATIONS AND

MAINTENANCE OF ELECTRICAL APPARATUS FOR USE IN POTENTIALLY EXPLOSIVE

ATMOSPHERES should be strictly observed. General recommendations are given in

BS5345:Part 1:1989. Specific requirements for flameproof (Type ‘d’), Intrinsically safe (Type ‘i’)

and increased safety (Type ‘e’) protection are given in BS 535: Part 3: 1979, BS 5345:Part 4:1977

and BS 5345: Part 6:1978 respectively.

For installations in North America, the national electrical code (NFPA 70 -1990) or later issues

should be strictly observed.

Elsewhere, the appropriate local or national regulations should be used.

The code of practice regarding SELECTION, INSTALLATION, USE AND MAINTENANCE OR

APPARATUS FOR THE DETECTION OF COMBUSTIBLE GASES (OTHER THAN FOR MINING

APPLICATIONS OR EXPLOSIVE PROCESSING AND MANUFACTURE) must be complied with.

Refer to BS6959:1988 in the UK o the appropriate local or national regulations.

3 Certification

The certification details and special conditions for use are shown below.

The Special Conditions for Safe Use are as follows:-

1. The integral supply cables must be mechanically protected and terminated in a

suitable terminal or junction facility.

2. In addition to the integral earth conductor, earth equipotential bonding may be

maintained via the rear mounting thread.

5 Installation

The Reflector Panel Heaters are designed to allow installation to be performed by a single

operator. The installation procedure is split into mechanical installation and electrical

installation.

5.1 Mechanical Installation

Follow these instructions carefully. Do not attempt to dismantle the Reflector Panel Heater in

any way.

5.1.1 Replacement of standard retro-reflector panels

If the Reflector Panel Heater is replacing a standard retro-reflector panel then the existing

duct cut out and mounting holes can be re used.

1. Ensure the system is switched off.

2. Loosen the 4 screws that clamp the retro-reflector assembly in position.

3. Lift the assembly up and outwards to release it from behind the screw heads.

4. Slot the Reflector Panel Heater assembly over the 4 screw heads and allow its

weight to be supported on the exposed sections of the thread.

5. Tighten the 4 screws to clamp the Reflector Panel Heater assembly in position.

5.1.2 Installation of Reflector Panel Heaters

If installing the Reflector Panel Heater to a new duct location follow the procedure below:

1. Stick the retro-reflector cut-out template to the outside of the duct wall opposite

the transmitter/receiver, ensuring that point X* is directly opposite point X on the

other template. (This will ensure that the transmitter’s IR beam hits the centre of

the retro-reflector).

2. Drill 6 mounting holes (7mm diameter) in the positions marked J on the template.

3. Following outline K, cut a square aperture in the duct wall.

4. Insert the two retro-reflector panel support bars through the aperture and attach

them to the inside of the duct using M6 washers and nuts. Ensure that the

threaded holes in the support bars line up with the holes drilled in the duct.

5. Fit four M6 x 16 cap head screws into the holes in the support strips but do not

tighten. Leave approximately 5mm of thread exposed on the outside of the duct.

6. Slot the retro-reflector assembly over the heads of the screws and allow its

weight to be supported on the exposed sections of thread. Tighten the four

screws to clamp the retro-reflector assembly in position.
