ETE Heat Shrink Marker Sleeves

Installation of Heat shrink Marker Sleeves

SAFETY

Failure to observe safe working practices can result in serious injury.

• Never use the electric hot air tool in the presence of water.
• Always shrink sleeves in a well-ventilated area.
• Surfaces will retain heat after the tool is turned off unless an adequate cool down period is allowed.
• Do not point the tool at anyone.
• Do not use or leave the tool near combustible material.

EQUIPMENT

CV- 1981 / CV-2014 Thermo gun (or similar controllable heat gun). PR 24 reflector (or similar curved reflector) Digital temperature meter – for temperature setting. K Type thermocouple – for temperature setting.

SCOPE

Full recovery of Identifications sleeves is dependent on many factors, time, material, temperature and wall thickness etc. This installation procedure applies to all TE Connectivity heat shrink sleeves and is designed to give a guide for full recovery in a reasonable amount of time.
Sleeve recovery will start at approximately 85°C (185°F) however, the time to full recovery may not be practical if many sleeves need to be installed. Therefore, this guide uses a hot setting to recover the sleeves quickly. Installers should determine the best conditions in their environment to achieve full recovery.

PROCEDURE

PLACEMENT

• Remove the sleeve from the carrier.
• ‘Open up’ the sleeve by pressing across the open end of the flat sleeve as in Fig.1.
• Do not crease the tubing along its complete length to apply to the wire (this may give rise to variable abrasion resistance of the print when in use)

• To aid the installation, the wire itself or another suitable tool i.e. a small screwdriver, can be inserted into the open end of the sleeve to ‘open up’ the sleeve.
• Slide the sleeve along the wire until it is in its required position.

RECOVERY (Shrinking)

• Ensure the sleeve is in the final position.
• Switch on the heat gun (typically setting 6) and allow to gun to stabilize. If the gun has not been previously calibrated, calibrate the temperature of the gun (see section 4.3).
• Aim the reflector towards one end of the sleeve; this allows directional control of the heat.
• Apply the heat to the printed side of the product (if possible).
• The reflector should be typically about 20mm from the marker sleeve, and no closer than 5mm.
• Start at one end of the sleeve and move around the circumference of the sleeve if space allows, and then move along and around the product until it is fully recovered.
• Return to the start point.
• It is recommended, to prolong air gun life, that the heat setting is returned to 0 and the gun allowed to cool before turning it off.
•  The reflector can be used vertically or horizontally depending on local access.
• Do not dwell on the sleeve in one point as this may give a local heat build-up/excess stress.
• Do not recover the sleeve on to sharp objects.
• The sleeve should not be recovered on to wires/cables greater than 80% of the minimum supplied diameter, (use a larger identification sleeve if necessary).

HEAT GUN SETTINGS – Calibration

Settings are dependant on the heat gun and reflector used. The temperature at the outlet of the PR26 reflector, using a Thermo gun (model CV-1981 / CV-1983), should be set to 215-245 o C. This is measured using a Type K thermocouple at the outlet of the reflector with temperatures read on a digital temperature meter.
The K Type thermocouple should be placed 5mm from the reflector surface at the central position of the reflector opening (see figure 2). The gun should be allowed to heat up and stabilize before taking measurements. Changing the heat gun setting can alter the temperature. Generally, for the CV-1981 / CV-1983 heat gun with a PR 24 reflector, a setting of 6 gives the required temperature.

NOTES AND PRECAUTIONS

After product recovery, outer surfaces will be hot and could cause damage to equipment in the local area. To prevent damage, ensure that the reflector does not touch other parts or the marker sleeve (the outer wire insulation can be distorted by surface contact with the reflector). When not in use, switch the gun off.
Do not touch the printed surface while the sleeve is still hot.
