7.3.5 Emptying the drip tray (if present)
Only valid for circulation pumps with mechanical seal.
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES

Risk of injury to the eyes, skin, respiratory tract.

The safety data sheet for the thermal fluid to be used must be read prior to using it and its
content must be respected.

Observe the local regulations/work instructions.

Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).

Danger of slipping because floor and work area are contaminated. Clean the work station and
follow the instructions for the disposal of thermal fluid and material on page 17 in section
»Proper disposal of resources and consumables« .
This is not an actual leak but residues that are necessary for the lubrication of the mechanical seal.
The exiting quantity of thermal fluid is dependent on the thermal fluid itself and the working tem-
perature of the temperature control unit. The drops in the drip tray usually evaporate in case of
thermal fluids with a high vapor pressure. The drops usually do not evaporate in case of thermal
fluids with a low vapor pressure (e.g. silicone oils). Therefore, these residues must be drained from
time to time.
PROCEDURE

Hold a suitable container, e.g. beaker, below the
>Drain drip tray<
[7]. The drips can be cleanly
