sure to follow
good wiring
practices and all
applicable codes.
Ensure that the

· Check that the available power will meet the
requirements.

· Ensure that the
compatible with the pump motor requirements.

· In the case of systems with more than one iQpump, follow
the above procedure for each iQpump and pump motor.

The mounting of the iQpump is extremely important
regarding environment and accessibility. Depending on your
system, there are various models available and the mounting
dimensions (footprint) may be different. Because the
mounting procedure is fairly extensive, it is beyond the scope
of this document; the user is referred to the iQpump User
Manual (Document No. TM.iQp.06) received with the
iQpump,
that you received and follow the procedure described in the
manual to ensure a safe and functional installation. In cases
where the system has more than one iQpump, refer to the
proper clearances required for adequate ventilation.

pay particular attention to:

· The clearances to be maintained around the enclosure
for adequate ventilation.

· The environmental specifications such as avoiding
excessive dampness, extreme temperatures, chemical
exposure, corrosive areas, etc. to avoid damage to the
equipment and to maintain safety.

Improper removal of the iQpump terminal cover as well as
front cover can cause extensive damage to the iQpump. To
avoid damage to these items, please pay particular attention
to the iQpump User Manual, Document No. TM.iQp.06,

Scaling

System Scaling: Enter feedback device maximum:

Example: Enter 200 for pressure transducer with a maximum of 200 PSI at 20mA.

When the iQpump is turned On and the feedback signal level (transducer) falls below this

level, the pump system will start after the time specified in P1-05 (default 1 sec).

Programming the Start Level as an Absolute Value

Start Level has to programmed to a positive value in order for the Start Level to be an

absolute value. Example: Start Level P1-04 set to 50 PSI and delay time P1-05 set to

5 sec. Pump system will start when the pressure drops below 50 PSI for 5 sec.

Programming the Start Level as a Delta Level from the System Set-Point

Start Level has to programmed to a negative value in order for the Start Level to be a

delta value from the set-point.

Example: Start Level P1-04 set to –10 PSI with a system set-point of 50 PSI and a delay

time P1-05 set to 5 sec. Pump system will start when the pressure drops below 40 PSI

(50 - 10) for 5 sec.

For submersible motors use service
factor amps (SFA).

Confirm number of poles

2 Pole Motor = 3600 RPM

4 Pole Motor = 1800 RPM

6 Pole Motor = 1200 RPM

8 Pole Motor = 900 RPM
