1 For your safety

2 Description

2.1 What is what?

Drager R 58 762 Comfort Vest Instruction Manual - Slide-in pockets with PCM
elements

1 Slide-in pockets with PCM elements

2.2 Functional description

The cooling elements made of PCM (phase change material) are integrated in the comfort vest to absorb the body heat of wearer.

When donning the comfort vest, the PCM is in a solid state of aggregation. As the ambient temperature rises, the PCM absorbs thermal energy and changes to a liquid state of aggregation.

Depending on muscular effort and ambient temperature, the cooling effect will last up to two hours.

2.3 Intended use

The comfort vest is a piece of clothing which reduces the body temperature of its wearer in hot environments as well as during physical work which causes perspiration.

2.4 Limitations on use

The comfort vest is not to be considered as personal protective equipment. The comfort vest offers no protection against flames, stabs, blows or similar dangers to the wearer.

3 Use

3.1 Preparation for use

The comfort vest must be checked prior to every use:

Check if all PCM elements are there.
Check if comfort vest and PCM elements are undamaged (see chapter 4 on page 6).
Operability check
The operability of the PCM elements is given, when the salt crystal mixture is in a completely solid state of aggregation
and the PCM elements have an even, flat shape.

If necessary, restore operability as follows:

Heat the PCM elements at +32 °C up to +40 °C, until the salt crystal mixture is entirely liquid.
Put the PCM elements on a horizontal, even surface, stroke until flat and store for at least 2 hours at less than +20 °C or at least 30 minutes at +8 °C.
The PCM elements will then have regained full operability.

NOTICE
To achieve the best possible comfort and the best principle of operation, the comfort vest should be worn above another thin piece of clothing (e.g. T-Shirt, undershirt, function shirt, …) which can absorb the sweat.

3.2 Use

The comfort vest must be worn close to the body to achieve a maximum cooling effect for the wearer.

NOTICE
The user should wear the correct vest size

3.3 After use

Open the Velcro fastener.
Put the comfort vest on a horizontal, even surface.
Stroke the PCM elements until flat. Ensure that the PCM elements are evenly distributed and lying horizontally, as this will ensure the best results when regenerating the PCM elements.
Store the comfort vest at a temperature of less than +20 °C for at least two hours, so that all PCM elements can change to the phase to the solid state of aggregation.
This process takes 30 minutes at an ambient temperature of +8 °C.
Check the comfort vest for damages (see chapter 4 on page 6).
If necessary, wash the comfort vest.

4 Maintenance

4.1 Cleaning

After removing the PCM elements, the comfort vest can be cleaned at max. +40 °C using a detergent for delicate fabrics.

4.2 Maintenance intervals

4.2.1 Yearly

Check 1x every year if comfort vest or PCM elements are damaged.

Have damages (e. g. cuts, tears, etc.) on the comfort vest repaired by a professional sewing shop.

If damaged (e. g. perforation of the packaging), replace the PCM elements.

4.2.2 Every 3 years

Even if handled with care, the PCM elements will lose their effectiveness as the amount of changes in state of aggregation and storage time rise. Replace the PCM elements after 3 years at the latest to ensure maximum performance of the comfort vest.

5 Storage

When all PCM elements have returned to a solid state of aggregation, put the comfort vest on a horizontal, level surface and open slightly and allow residual moisture to evaporate.
The storage temperature may not exceed +22 °C. Store the comfort vest in a dark, dry and well aerated room. Avoid UV and direct sun irradiation as well as ozone.

6 Disposal

Without PCM elements, the vest can be disposed of in the domestic garbage.
The PCM elements must be disposed of according to European Waste Catalogue key number EWC 160507 and in accordance with local waste management regulations.
