- try to use a power switch in order to have separate connections via contact relay or relay. - when this is not possible, contact EMAUX technical service. d. Install the pump as shown in fig.4 bearing in mind that: - ensure that max system pressure corre sponds to unit max pressure data (see performance curves). - Page 7 NOTE In case of priming difficulties: use a normal syringe to suck liquid from the discharge nipple while the pump is in operation (air bleed valve closed), continuing until you actually see the liquid rise in the syringe. Use a short piece of suction hose to connect the syringe to the discharge nipple (refer parag.”TROUBLESHOOTING”).
