Prerequisites

If needed, update the firmware of the hosting sampler to ensure that it supports the type of thermostat you are about to install, see Specifications of the Sample Thermostat.

WARNING

Flammable refrigerant

Formation of flammable gas-air mixtures inside the Sample Thermostat and laboratory.

Keep open fire or sources of ignition away from the device.
Ensure a room size of 4 m³ (1 m³ for every 8 g of R600a refrigerant inside of the Sample Thermostat).
Ensure adequate ventilation: typical air exchange of 25 m³/h per m² of laboratory floor area.
Keep all ventilation openings in the enclosure clear of obstructions. Do not block the openings on the circumference of the Sample Thermostat.

WARNING

Flammable refrigerant used

When handling, installing and operating the Sample Thermostat, care should be taken to avoid damage to the refrigerant tubing or any part of the Sample Thermostat.

WARNING

In the event of a damage

Keep open fire or sources of ignition away from the device.
Ventilate the room for several minutes.
Do not use the Sample Thermostat any more.

WARNING

Heavy weight

The module is heavy.

Carry the module at least with 2 people.
Avoid back strain or injury by following all precautions for lifting heavy objects.
Ensure that the load is as close to your body as possible.
Ensure that you can cope with the weight of your load.

CAUTION

Routing of the condensation tubing

Proper routing of the condensation tubing is critical for correct condensate drainage.

Do not place the sampler directly on the bench.

CAUTION

Condensate inside the module

Damage to the electronics of the module

After installation of the Sample Thermostat, wait at least 30 min before switching on the module.
Make sure there is no condensate inside the module.

Ensure that no condensate remains inside the thermostat before proceeding forward.

NOTE
Gently tapping on the sides of the sampler can help to remove the last traces of condensate from the system.
Loosen the screw (1) and remove the condensate funnel (2) from the back of the thermostat.

NOTE
If there is still some condensate inside the thermostat, place a suitable container underneath the outlet tube, and keep tapping on the sides of the sampler until no more water comes out.
Pull the thermostat halfway out, disconnect the power and the data cable and then remove the unit completely from the sampler.
Damage to the cables. Do not bend or pinch the cables. Fit in the Sample Cooler/Sample Thermostat perfectly.
CAUTION
Damage to the cables.
- Do not bend or pinch the cables.
- Fit in the Sample Cooler/Sample Thermostat perfectly.
Slide the cooler/thermostat all the way into the sampler, making sure that the cables don’t get jammed between the metal parts.
Position the condensate collector funnel underneath the condensate drainage outlet tube (1) and fix it to the back of the thermostat by tightening the screw (2). Ensure correct orientation and avoid overtightening the screw.

NOTE
For information on proper condensate handling, see G5668A, G7137A, G7167A, G7167B Multisampler Install the Sample Thermostat.
Position the condensate collector funnel underneath the condensate drainage outlet tube (1) and fix it to the back of the thermostat by tightening the screw (2). Ensure correct orientation and avoid overtightening the screw.

NOTE
For information on proper condensate handling, see Install the Sample Thermostat for the G7129A Vialsampler, G7129B Vialsampler, G7129C Vialsampler.
CAUTION
Damage to the Sample Thermostat
- Wait at least 30 min before switching on the compressor of the thermostat.
- This allows the refrigerant and system lubrication to reach equilibrium.
Switch on the sampler and perform the Sample Cooler Function Test to verify the correct functioning of the new thermostat, see Sample Cooler Function Test.
