Product Information; Technical Data; Safety Rules - Wilo VeroLine-IPL Instrucciones De Instalación Y Funcionamiento

English
1 General
Installation and service by qualified personnel
only.
1.1 Fields of applications
Series IPL (Inline) and DPL (Dual) glanded pumps
are used for circulating duties in mechanical build-
ing services to serve:
• Central hot water heating systems
• Chilled and condenser water systems
• Closed industrial circulating systems
• Heat transfer systems.

Standard design
Special design or additional equipment at extra cost
Alternative application of standard design (no additional costs)
When ordering spare parts, all data of pump and
motor name plate must be stated.
Permissible fluids:
When using water/glycol mixtures of a mixing
ratio up to 40% glycol (or fluids of viscosities
other than water) it will be necessary to correct
the hydraulic pump data according to the higher
viscosity, depending on the mixing ratio and
the fluid temperature. Only approved makes of
additives with corrosion inhibitors in strict com-
pliance with manufacturers` instructions must be
used.
The fluid must be free of sediments.

2 Safety rules

These instructions contain basic rules on safety
aspects which must be strictly adhered to for
installation and operation. It is therefore impera-
tive for Installers and Operators to study these
