Installation Guide

Do not use the pump to vent the system. Do not start
the pump before filling the system. Never operate
the pump dry.
The pump should be manually vented as follows to prevent
the possibility of any bearing damage at start-up. The
pump will continue to automatically vent air once manually
vented.
1. Once the system has been filled and vented, open the
isolation valves and slowly remove the indicator plug
in the middle of the nameplate.
2. Allow the air to purge from the pump until water
appears. While air is venting, gently turn shaft and
move it in and out, with a small flat blade screwdriver.
Protect the terminal box from getting wet. After air
has been vented, install and retighten the plug. The
pump can now be started.
GRUNDFOS domestic circulating pumps, installed
properly and sized for correct performance, will operate
quietly and efficiently and provide years of service.
Under no circumstances should the pump be operated
without water circulation or without the minimum required
inlet pressure for prolonged periods of time. This could
result in motor and pump damage.
UPS model pumps are multispeed, and the speed can be
changed by a speed selector switch located on the front
of the terminal box. UP models are single speed.

Start-Up
Operation
Failure to Operate
When the pump is first started, the shaft may rotate slowly
until water has fully penetrated the bearings. If the pump
does not run, the shaft can be rotated manually. To
accomplish this, switch off the electrical supply, and close
the isolation valves on each side of the pump. Remove
the indicator plug in the middle of the nameplate. Insert a
small flat blade screwdriver into the end of the shaft, and
gently turn until the shaft moves freely (see Figure 7).
Replace and tighten the plug. Open the isolation valves
and wait 2 to 3 minutes for the system pressure to equalize
before starting the pump.
NOTE: After a long shut down multi-speed pumps should
be started on speed 3 and then adjusted to the regular
setting. The UPS 15-42 has automatic function to assist
in restart.
