2 Check The Condition Of The Pump; 3 Verify Electrical Requirements; Pumped Liquid Requirements - Grundfos SuperBrute XL Installation And Operating Instructions Manual

2.2 Check the condition of the pump

The pump's shipping carton is specially
designed around the pump during production
to prevent damage.
As a precaution, it should remain in the carton
until you are ready to install it. At that point,
look at the pump and examine it for any
damage that may have occurred during
shipping.
Examine any other parts of the shipment as
well for any visible damage. Once the pump
has been removed from the box, care should
be taken NOT to drop or mishandle the pump.
Box contents:
• one pump
• two gaskets (flanged units only)
• one Installation and Operation Instruction
(I&O).

2.3 Verify electrical requirements

Verify the electrical supply to be certain the
voltage, phase and frequency match that of
the pump motor. The proper operating voltage
and other electrical information can be found
on the pump nameplate.
This pump's motor is designed to run on
+ / - 10 % of the nameplate-rated voltage.

2.4 Pumped liquid requirements

The Grundfos SuperBrute XL,
UP/UPS pump is intended for
use with water only. The pump
must not be used for the transfer
of flammable liquids such as
Caution
diesel oil, gasoline, and similar
liquids.
The pump is not for pool or
marine use.
The pump can be used to circulate:
• Potable hot water.
• Water containing glycol for hydronic heating
(see section 7. Additional technical data for
additional limitations).
• Cooling water.
In domestic hot-water systems it is advisable
to use stainless steel pump housing versions
of this pump.
All pump types (stainless, bronze or cast iron
pump housing) should not be used in water
with a degree of hardness lower than 14 grains
per gallon of hardness.
Fluids should be clean and should not contain
solid particles, fibers, or mineral oils.
If the pump is installed in a heating system, the
water should meet the requirements of
accepted standards on water quality in heating
systems. The fluid should not contain solid
particles, fibers, or mineral oils.

The pump is lubricated and cooled by the
liquid being pumped. Therefore, the pumped
liquid must always be allowed to circulate
through the pump.
Extended periods without circulation will cause
premature wear to the bearings and excessive
motor heat.
The pumped liquid must meet the temperature
requirements listed in the following charts.
Note: Fluid must never be allowed to freeze
during non-operational periods.
