17.1. Pump connection with HSP booster pump
Caution: Securely attach all tubing to prevent slipping.
Important:
:
If an HSP booster pump is used, the pump connections (21, 22) cannot be used any

Cooling capacity using a HSP booster pump:
If a HSP booster pump is used, the ultra-low refrigerated circulators do not reach the specified lowest
bath temperature because the pump dissipates frictional heat of approx. 400 W to the bath fluid.
