CONGRATULATIONS!

You are now the fortunate owner of a MixiMizerTM

PUMP. It has been carefully inspected and tested

before shipment. It should give you long, efficient,

trouble-free service. For maximum performance and

reliability, please follow the simple instructions in this

manual.

Since mixing by a variable speed injection pump is a

relatively new concept, there are a few simple piping

details that should be considered.

Variable speed injection systems require complete

isolation between the boiler loop and system loop. For

example, when the injection pump is turned off, there

must be no heat transfer from the boiler loop to the

system loop. In order to avoid this unwanted heat

transfer, standard primary-secondary piping tech-

niques are used.

This piping arrangement requires that the injection

piping be at least one pipe diameter smaller than the

piping of the boiler and system loops.

Note 1:

There must be a maximum of 4 pipe diameters

between the tees in the boiler and system loops in

order to prevent ghosts flow when the variable speed

injection pump is off and either the boiler pump or

system pump is on.

Note 2:

There must be at least 6 pipe diameters of straight

pipe on either side of the tees in order to prevent

momentum of water in the boiler and system loops

from pushing flow through the injection loop.

safety precautions should always be followed, including

the following:

The installer must ensure that this control and its wiring

are isolated and/or shielded from strong sources of

electromagnetic noise. Conversely, this Class B digital

apparatus complies with Part 15 of the FCC Rules and

meets all requirements of the Canadian Interference-

Causing Equipment Regulations. However, if this

control does cause harmful interference to radio or

television reception, which can be determined by

turning the control off and on, the user is encouraged

to try to correct the interference by reorienting or

relocating the receiving antenna, relocating the receiver

with respect to this control, and/or connecting the

control to a different circuit from that to which the

receiver is connected.

CAUTION: The non-metallic enclosure does not

provide grounding between conduit connections. Use

grounding type bushings and jumper wires.

CAUTION: Improper installation and operation of this

control could result in damage to the equipment and

possibly even personal injury. It is your responsibility

to ensure that this control is safely installed according

to all applicable codes and standards. This electronic

control is not intended for use as a primary limit control.

once the heat demand is removed or control

enters WWSD. The purging holds the last speed

used.

• As variable speed output modulates, the control

flashes the % of Pump Performance LED on for ¼

second and off for ¼ to 2 1/2 seconds.

• A 2 second delay from demand to actually starting

the pump is used to prevent issues with a noisy

demand relay signal.

4. Pump Installation

Remove the control from the pump and install pump in

injection loop

Position of terminal box:

Prefered installation of the pump will have the terminal

box located to one side of the pump or the other, with

the conduit entry down.

Page 6

If the terminal box position needs to be changed, it is

best to do so before installation. However, if the pump

is already installed, ensure that the electrical supply is

turned off and close the isolation valves before

removing the Allen screws.

To Change terminal box position:

• Remove the four (4) Allen screws (4 or 5mm

wrench) while supporting the stator (motor).

• Carefully separate the stator from the pump

chamber and rotate it to the correct terminal box

orientation.

• Replace the Allen screws and tighten diagonally

and evenly (7 ft. –lb. torque).

• Check that the motor shaft turns freely. Remove

the large screw in the middle of the nameplate,

insert a small flat blade screwdriver into the end

of the shaft, and turn gently.

• If the shaft does not turn easily, repeat the

disassembly/reassembly process.

Pump Mounting: For Indoor Use Only

Arrows on the side or bottom of the pump chamber

indicate direction of flow through the pump. Grundfos

Miximizer pumps can be installed in both vertical and

horizontal lines. Flow direction should be from the

boiler/supply loop into the system loop.

The pump must be installed with the motor shaft

positioned horizontally. Under no circumstances should

the pump be installed with the shaft vertical or where

the shaft falls below the horizontal plane (Fig.4C).

5.Installation Requirements

• Thoroughly clean and flush the system prior to

pump installation

• Ensure that water does not enter the terminal box

during the installation process.

•DO NOT STARTTHE PUMP UNTIL THE

SYSTEM HAS BEEN FILLED AND CHECKED

FOR LEAKS.

• Do not use the pump to vent the system.

• Never operate the pump dry. The bearings

require water lubrication and will be damaged

otherwise.

• Fill system with water. This will result in immedi-

ate lubrication of the bearings.

• Operate the pump for 5 minutes, when control

installation is complete, to purge remaining air

from the bearing chamber. This is especially

important when installing the pump during the off-

season.

6.Mounting Control System

Provisions for a 115 V grounded outlet within 6 feet of

the pump mounting location, should be made.

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.

Install a 2” x 4” duplex electrical box to house low

voltage wiring for connection to the control.

Outdoor Air Temperature Sensor 070

The Outdoor Air Temperature Sensor 070 includes a 10

kW thermistor which provides an accurate measure-

ment of the outdoor temperature. The 070 sensor is

protected by a white U.V. resistant PVC plastic

enclosure (Fig. 6A & 6B).

Note: The outdoor air temperature sensor 070

(thermistor) is built into the PVC plastic enclosure.

• Remove the screw and pull the front cover off the

sensor enclosure.

• The 070 can either be mounted directly onto a

wall or a 2” x 4” electrical box. When the 070 is

wall mounted, the wiring should enter through the

back or bottom of the enclosure. Do not mount

the 070 with the conduit knockout facing upwards

as rain could enter the enclosure and damage the

sensor (Fig. 6C).

Figure 6C - Mounting the Sensor

• In order to prevent heat transmitted through the

wall from affecting the sensor reading, it may be

necessary to install an insulating barrier behind

the enclosure.

• The 070 should be mounted on a wall which best

represents the heat load on the building (a

northern wall for most buildings or a southern

facing wall for buildings with large south facing

glass areas). The 070 should not be exposed to

heat sources such as ventilation or window

openings.

• The 070 should be installed at an elevation above

the ground that will prevent accidental damage or

tampering.

Water Temperature Sensor 071

The Water Temperature 071 Sensor has a zinc sleeve

for fast response and a wide operating range (Fig 6D).

Note: The 071 sensor is designed to mount on a pipe

or in a temperature immersion well.

• The 071 sensor can be strapped directly to the

pipe using the cable tie provided. Insulation

should be placed around the sensor to reduce the

effect of air currents on the sensor measurement

(Fig. 6E).

• The 071 sensor should be placed downstream of

a pump or after an elbow or similar fitting. This is

especially important if large diameter pipes are

used as the thermal stratification within the pipe

can result in erroneous sensor readings. Proper
