In order to protect against frost damage during transport and storage, SP pumps are protected by a water/glycol mixture. Although glycol is not toxic, after the elimination of water hazard class ‘0’ (WHC 0 = not hazardous to water), this substance was shifted into water hazard class ‘1’ (WGK 1 = slightly hazardous to water). Although a minimum limit of 200l/kg applies to the above-mentioned group, some district-level water authorities have separate regulations requiring the motor fluid to be completely glycol-free.
Before installing the pump, please contact the competent district-level water authority in this regard. It is a simple matter to drain the motor fluid on location and replace it with normal tap water (see operating instructions). The instructions are also available online on the product pages under the tab called Documentation.
