by abnormal operating conditions, accident,
abuse, misuse, unauthorized alteration or repair,
or if the product was not installed in accordance
with Grundfos' printed installation and operating
instructions.
To obtain service under this warranty, the
defective product must be returned to the
distributor or dealer of Grundfos' products from
which it was purchased together with proof of
purchase and installation date, failure date, and
supporting installation data. Unless otherwise
provided, the distributor or dealer will contact
Grundfos or an authorized service station for
instructions. Any defective product to be

Warning
Prior to installation, read these
installation and operating
instructions. Installation and
operation must comply with local
regulations and accepted codes of
good practice.

2. Introduction
2.1 Safety warning
2.1.1 Read this booklet
This booklet is designed to help a certified
installer install, begin operation of and
troubleshoot the Grundfos UP Series 200
pumps. The 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.
2.2 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.
3. Pre-installation checklist
3.1 Confirm you have the correct pump
• Read the pump nameplate to make sure 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?
3.2 Check the condition of the pump
The shipping carton your pump came in is
specially designed around your 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.
3.3 Verify electrical requirements
Verification of the power supply should be made
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.
These motors are designed to run on ± 10 % of
the rated voltage.
Wiring diagrams can be found inside the
terminal box cover and later in these installation
and operating instructions. If voltage variations
are larger than ± 10 %, do not operate the pump.
Warning
A faulty motor or wiring can cause
electric shock that could be fatal,
whether touched directly or
conducted through standing water.
For this reason, proper grou nding
of the pump to the power supply's
grounding terminal is required for
safe installation and operation.
In all installations, the aboveground metal plumbing should be
connected to the power supply
ground as described in
Article 250-80 of the National
Electrical Code.

3.4 Pumped liquid requirements
The pump can be used to circulate the following
liquids:
• potable hot water
• water for hydronic heating
• water/glycol mixtures up to 50/50
• cooling water.
In domestic hot-water systems it is advisable to
use bronze pumps (UP Series 200 or UPS
model) only for water with a degree of hardness
lower than 14 grains per gallon of hardness. For
water with a higher degree of hardness, a directcoupled TP pump is recommended. If the pump
is installed in a heating system, the water should
meet the requirements of accepted standards on
water quality in heating systems.
In water/glycol mixtures, in order to prevent the
glycol from degrading, temperatures above
those for which the liquid is rated should be
avoided and time spent at high temperatures
minimized.
It is also important that the system is cleaned
and flushed prior to the installation of the glycol
mixture.
In order to avoid problems with corrosion or
precipitation, the glycol liquids should be
checked and maintained regularly. If further
dilution of the supplied glycol is required, follow
the requirements of the supplier of the glycol.

The pump is lubricated and cooled by the
pumped liquid. 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 liqui d must
also meet the following requirements:
Minimum inlet pressure (during operation)
Liquid temperature range
Continuously:
14 °F (-10 °C) up to 230 °F (110 °C).
Intermittent:
< 284 °F (140 °C) for short periods of time.
Domestic hot water:
< 140 °F (60 °C).
4. Installation procedures
4.1 Electrical preparation
Terminal box position
At the bottom of the stator, closest to the pump
housing, there are eight drain holes to allow
condensed water to escape. The drain holes
must not be blocked. The drain holes must point
downwards. The terminal box must therefore
point upwards in one of the positions shown in
fig. 1. The following terminal box positions apply
whether the piping is mounted vertically or
horizontally.
Fig. 1 Possible terminal box positions
Caution
The UP Series 200 pump is
intended for use with water only.
Caution
Glycol with the trade name
DEXCOOL
®
can damage the pump.
