terminal box during the installation process.

2. DO NOT START THE PUMP until the

system has been filled and checked for

leaks.

3. Do not use the pump to vent the system.

4. Never let the pump run dry. The bearings

require water lubrication and will be

damaged otherwise.

5. Fill system with water. This will result in

immediate lubrication of the bearings.

6. Thoroughly clean and flush the system prior

to pump installation.

7. Operate the pump for 5 minutes, when

controller installation is complete, to purge

remaining air from the bearing chamber.

This is especially important when installing

the pump during the off-season.

8. When making pipe connections, be sure to

follow the pipe manufacturer's

recommendations and all code requirements

for piping material.

6.2 Mechanical installation

6.2.1 Preferred pump and terminal box

orientation

Arrows on the side or bottom of the pump

housing indicate direction of flow through the

pump.

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. See fig. 1.

Fig. 1 Terminal box orientation

6.2.2 How to change terminal box position

How to change terminal box position:

1. Remove the four (4) hex socket head screws

(4 or 5 mm wrench) while supporting the

stator (motor).

2. Carefully separate the stator from the pump

housing and rotate it to the correct terminal

box orientation.

3. Replace the hex socket head screws and

tighten diagonally and evenly (7 ft.-lb. torque).

4. 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.

5. If the shaft does not turn easily, repeat the

disassembly/reassembly process.

Caution

Consult pipe manufacturers for

material selection before installing

this pump. Absence of pumped

liquid may damage some piping

materials.

Caution

Thoroughly clean and flush the

system prior to pump installation.

Caution

For indoor use only.

Warning

If the terminal box position needs

to be changed, ensure that the

power supply is turned off and

close the isolating valves before

removing the hex socket head

screws.

Test the speed control signal wiring

Make sure exposed wires and bare terminals

are not in contact with other wires or grounded

surfaces. Turn on the control signal and

measure the voltage/mA across the wires using

a voltmeter to confirm the pump signal is

present.

Warning

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

Power must not be applied to any

voltage supply wiring.

Caution

All field wiring must pass through a

suitable, listed conduit fitting, to

ensure proper strain relief.

Caution

All field installed wiring should

meet or exceed requirements for

Class 2 wiring per article 725 of the

National Electrical Code rated at

30 VAC 250 VA. Ensure that enough

wiring is in the terminal box to

reach the terminal board.

Note

All field wiring shall have insulation

stripped exposing 5-7 mm of

conductor before placement into

terminal box terminal board.

Warning

The installer should make sure that

no current/voltage is present at any

of the wires.

7. Settings

7.1 Setting the dip switches

Fig. 4 Dip switches

7.1.1 Dip switch settings

7.2 Speed settings

7.2.1 Dip switch C

Minimum speed off / minimum speed 15 %

When dip switch C is in the ON position the

variable speed of the pump will have a range

from minimum speed = off to maximum speed

= 100 %. When dip switch C is in position OFF

the variable speed of the pump will have a range

from minimum speed = 15 % to a maximum

speed = 100 %.

7.2.2 Dip switch D

Speed control external / speed control

maximum % dial

When dip switch D is in position ON, an

external V(DC)/mA signal will cause the pump

speed to vary and the dial on the terminal box

will function in the -5 % to +5 % mode. When dip

switch D is in position OFF, turning the manual

% dial will vary the pump speed. The pump will

not respond to an external V(DC)/mA signal

even if one is present. The terminal box and the

dial will function in the minimum to 100 % mode.

7.2.3 Multi function dial on terminal box

Offset dial (when dip switch D is on)

The Offset dial allows the user to fine-tune the

input signal. The input signal may be varied plus

or minus 1-5 %. This offset will affect the signal

through its entire range. The factory default is 0.

The offset setting cannot increase the output to

more than 100 % or less than the selected

minimum output of either 0 % or 15 %.

Example:

The measured input signal is 2.1 - 10.1 V and as

a result the pump does not shut off because the

signal does not drop to 2 V. The dial is set to

-5 % and the input signal is offset down to

2.0 - 9.6 V. The pump will now shut off; however

the pump will not reach the full 10 V speed now,

due to the offset.

7.2.4 Manual % dial (when dip switch D is off)

The manual % dial allows the speed of the pump

to be manually adjusted and set by the user.

The speed of the pump may be manually

adjusted anywhere from "Min" to "100 %", but

once set remains fixed at that speed. The "Min"

position on the dial will either be equal to OFF or

15 % depending on the position of dip switch C.

The factory default is 50 %.

Insert power cord from the pump into a properly

grounded 115 V outlet. This will apply power to

the pump/controller.

7.2.5 Performance indicator LEDs

"Power On" (green) indicates that power is

applied.

"% Out" (yellow) indicates the speed of the

pump by flashing at different speeds.
