3. Safety warning
3.1 Read this booklet
This booklet is designed to help a certified
installer to install, begin operation of, and
troubleshoot the Grundfos Small UP and UPS
pumps.
Following the instructions will ensure safe,
trouble-free operation.
This booklet should be left with the owner of the
pump for future reference and information
regarding its operation. Should the owner
experience any problems with the pump, a
certified professional should be contacted.
3.2 Electrical work
All electrical work should be performed by a
qualified electrician in accordance with the latest
edition of the National Electrical Code, local
codes and regulations.
Warning
A faulty motor or wiring can cause
electrical shock that could be fatal,
whether touched directly or
conducted through standing water.
For this reason, proper grounding of
the pump to the power supply's
grounding terminal is required for safe
installation and operation.
In all installations, the above-ground
metal plumbing should be connected
to the power supply ground as
described in the National Electrical
Code. All wiring must comply with the
National Electrical Code, state, and
local regulations.

4. Pre-installation checklist
4.1 Confirm you have the correct pump
•
Read the pump nameplate to ensure it is the
one you ordered.
•
Compare the pump's nameplate data and its
performance curve (for head, gpm, etc.) with
the application in which you plan to install it.
•
Will the pump do what you expect it to do?
4.1.1 Pump to system type recommendations
•
Open systems (i.e. potable water): Stainless
steel or bronze volute (pump housing) only.
•
Closed systems (i.e. airless, non-potable
water): Cast iron, stainless steel, or bronze
volute (pump housing).
Other considerations regarding Grundfos small
UP and UPS pumps:
•
These pumps are intended for indoor use
only.
•
If installed outdoors the pump must be
protected by an appropriate, well ventilated,
water-tight enclosure to keep out moisture
and dirt.
•
Minimum ambient temperatures must be no
lower than 33 °F (1 °C).
•
For ambient and fluid temperature see

4.2 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.
