5 OPERATING INSTRUCTIONS
5.1 OPERATION
Checks to be performed before start-up:
• Th pump is suppli d without any oil in it. Us th suppli d oil or an oil lubricant indicat d on th id ntification plat
of this pump (s ch. 3.3) or, alt rnativ ly, an alt rnativ lubricant of anoth r brand but with similar charact ristics;
• Mak sur th pump outl t is not obstruct d by fittings.
WARNING
A quantity of oil that exceeds the necessary quantity may cause the clogging of oil separators and
damage to the pump or to the electric motor.
Operation without lubricant causes serious damage to the pump.
5.1.1 FILLING THE OIL TANK
WARNING
When filling the oil tank never exceed allowed maximum level.
• Undo th oil fill r plug;
• Pour oil in th tank up to mid-rang of th oil sight glass or oil vi w r;
• Clos th fill r plug and wip off any spills from th tank.
5.1.2 START-UP
HAZARD
The pump may reach high temperatures when operating.
Aft r start-up, th pump may run slow r than th r gular rpm if room t mp ratur is low r than allow d as s n on
th t chnical data tabl . It may also run low r if th oil is contaminat d or th supply voltag is low r than th
r quir d voltag as indicat d on th motor rating plat .
If nominal rpm is not r ach d within a f w s conds, th th rmal switch fitt d to prot ct th pump must trip
