Use At Lower Temperatures - Grant GD100 Bedienungsanleitung

2.2.6 Use of pump on GD120.
To use the pump, remove the pump bypass moulding and replace with the
pump output moulding.
Remove the two screws which hold the pump bypass moulding to the control
unit, and using the screws fit the pump output moulding. Ensure that the two
sealing „O‟ rings are correctly fitted into their grooves before fitting. Retain the
pump bypass with its longer screws for refitting when the pump is no longer
required.
Connect the outlet pipe, marked with an upward arrow on the left hand pipe, to
the external circuit. Connect the return pipe to the inlet pipe, marked with a
downward arrow. Secure the pipes with clips.
The pump will pump liquid around a closed external circuit, which is one not
open to the atmosphere. It cannot be used for circulation through an external
open tank.
WARNING: If the operating temperature is greater than 60° C, ensure that the pipes are
securely clamped to pump outlet and to the external circuit, and that the tubing is suitable
for both the liquid and the temperature.
2.3

Use at lower temperatures.

Due to heat input from the pump and stirrer motor, the minimum operating temperature
without accessory cooling depends on the size of the bath. The smallest baths, P5 and
S5, have an operating temperature of approximately 10° C above ambient without a lid
(15º with a lid).
The other baths can be used at a temperature of 5° C above ambient without accessory
cooling.
For lower temperature operation, accessory cooling is required.
