CAUTION
with all LMI metering pumps. Please read this section
carefully prior to installation.
ALWAYS wear protective clothing, face shield, safety
glasses and gloves when working on or near your
metering pump. Additional precautions should be taken
depending on the solution being pumped. Refer to
MSDS precautions from your solution supplier.
All LMI pumps are pre-primed with water when shipped
from the factory. If your solution is not compatible with
water, disassemble the Pump Head Assembly.
Thoroughly dry the pump head, plunger, and check
valve components. Reassemble head assembly
tightening screws in a crisscross pattern. Refill the
pump head with the solution to be pumped before
priming the pump. (This will aid in priming.)

Electrical Connections
WARNING: to reduce the risk of electrical shock, the
metering pump must be plugged into a grounded outlet
!
CAUTION
with ratings conforming to the data on the pump
control panel. The pump must be connected to a good
ground. DO NOT USE ADAPTERS! All wiring must
conform to local electrical codes.
6.0 Installation Instructions
The minimum allowable system pressure for the
HH pump is 200 psi. If your system operates at
a lower pressure, a back pressure valve must be
installed.
6.1 Pump Location
Locate the pump in an area convenient to the solution tank and
electrical supply. The pump should be accessible for routine
maintenance, and should not be subjected to ambient temperatures
above 122°F (50°C).
9
Page 10
6.2 Pump Mounting
The HH pump requires a Flooded Suction installation. The pump
should be securely mounted at the base of the storage tank with the
suction piping sloping downward to the pump.
All piping should be cleaned and blown-out
prior to connection to the HH pump.
6.3 Plumbing
Always adhere to local plumbing codes and
requirements. Be sure the installation does not
!
CAUTION
The HH high pressure metering pump utilizes 1/4" N.P.T.
connections. These connections require the use of Teflon Tape.
When applying the Teflon Tape, make sure it does not extend over
the fitting. This would restrict the flow of chemical.
All piping being attached to the HH must be cleaned and blown out
to prevent debris from entering the Liquid End. A 100 micron
strainer or filter should be installed to prevent any debris in the
chemical from entering the pump.
constitute a cross connection. Check your local
plumbing codes for guidelines. LMI is not
responsible for improper installations.
10
Both the discharge and suction check valves
should be supported while tightening the mating
pipe connections. This is done by placing a
wrench on the check valve flat, to prevent it
from turning and becoming over tightened,
when connecting the pipe.
Page 11
The discharge piping must be installed and supported so that it does
not place a supportive load on the liquid end.
Series HH pumps are capable of developing 1000

CAUTION
For calibration purposes, it is recommended that a 200 mL graduated
cylinder be piped in-line, on the suction side of the pump (see
Figure 4).
psi of discharge pressure. All piping must have
sufficient rating to withstand maximum pressure.

6.4 External Control Connections
The HH7 and HH9 come standard with various electrical connectors.
These are located on the front of the pump. The functions and
appropriate connections are covered in greater detail later in this
manual.
The HH pump comes equipped with a 1/8" NPT port on the bottom
of the liquid end spacer. This port is provided for draining in the
event that the seal stack leaks. Use a 1/8" NPT, Teflon taped
connector to safely route any leakage to a suitable container.

6.5 Priming and Operation
LMI performance tests every pump prior to shipping to insure that
it meets the design parameters. This test is performed using water.
Please be advised that the pumps are shipped with water in the
Liquid End. If it is incompatible with the chemical that is being
injected, the head must be dried.
When all of the previously mentioned precautions and safety
regulations required by your facility or local ordinances have been
considered, you may start priming your pump.
The HH precisely injects small amounts of
chemical. Due to this characteristic, the HH will
take a considerable amount of time to prime.
System design may also affect the priming time
The HH9 Control Panel has a Start/Stop button
labeled "Hold for Prime". This key has a timer that
shuts off after one minute of operation. The
lengthy priming time of the HH renders this
function unusable. The priming procedure should
be done with the pump running in the internal
mode.
12
Step 1- Plug in or switch on your pump
Step 2- While the pump is running, turn the stroke dial
knob to 100% and the speed adjustment knob (if equipped)
to 80%.
Step 3- Make sure that any valves are open to allow
chemical to enter the pump head.
Page 13
7.0 Output Adjustment Controls
Once the pump is primed, the output must be adjusted to meet the
requirements of the system. This adjustment is made by varying
both the stroke and speed of the pump.
7.1 Pressure Control Adjustment (HH9 Only):
The pressure control adjustment, unique to LMI, allows for the fine
tuning of your HH9 Pump. This reduces over pumping of chemical
and power consumption while increasing the accuracy and life of
your pump.(See Section 11.3)
7.2 Speed Adjustment:
The HH9 speed control can be adjusted manually, using the keypad
or externally as described in section 11. In either case, the speed
adjustment controls the frequency or rate at which the chemical is
being injected.
The HH1 and HH7 come equipped with a manual speed adjustment
knob. Turning the knob clockwise to the maximum setting increases
the stroke rate up to 100 strokes per minute.
HH7 Only:
When operating the pump in external mode, the
speed control knob should be turned fully counter
clockwise.
13
Page 14
7.3 Stroke Adjustment:
The Stroke Adjustment dial controls the volume of chemical being
injected with each stroke. The 100% setting indicates the maximum
volume per stroke.
The maximum rated output of your pump is
indicated on the data plate. The HH output
control features have been designed to make it
easy for the user to determine the appropriate
speed and stroke settings.
7.4 Calibration
The HH has been designed to inject a precise, repeatable amount of
chemical against system pressure. Because every system is different,
it is necessary to calibrate the pump once it is installed. The
calibration will enable you to fine tune the HH to provide the desired
injection amount.
The HH calibration is done after the pump is fully primed. The
discharge or injection point must be at normal operating pressure
for an accurate calibration to be done.
The suction line should be valved to run off the in-line calibration
cylinder. This cylinder must reproduce the suction pressure applied
by the tank (see Figure 4).

12.1 Programming the Pulse Divide Value
The divide value is altered by using the
( Up) and (Down)
keys. To do this, the pump must be in the External Divide mode and
be OFF. The valid range for the divide value runs from 1 to 999. With
the pump running in the Divide mode, the speed in SPM is calculated
based on the rate of incoming pulses and the divide value, and
EXT
displayed on the LCD screen
If the calculated speed is less than one (1) SPM, the LCD screen
will display 0 SPM. If the calculated speed is GREATER THAN

Page 27
12.2 Programming the Pulse Multiply (Batch) Value
The multiply value is altered by using the
(Up) and (Down)
keys to change the value. The pump must be OFF and in the External
Multiply mode. Like the divide value, the valid range for the multiply
value runs from 0 to 999 pulses. When the pump is ON, a single
external pulse will initiate a batch of pump strokes. The number of
EXT
remaining pulses are displayed on the LCD screen
X
. When
0 is reached, the display resets to the multiply value. The pump is
now ready for another pulse input.
If a pulse is received before the countdown to 0 is complete, the E4
error code is displayed, and the pump batch count resets to the
programmed multiply value. The batch countdown then continues
from its programmed value. As the countdown continues, the E4
error code
X
will be displayed intermittently until the fault is
EXT
corrected. The strokes that remained from the first batch are NOT
accounted for. To clear the fault display, the pump must be stopped
and restarted.
To allow true flow proportioning, the speed in the Multiply mode
is equal to the speed set in the Internal (manual) mode. That
is, if the Internal mode speed is set at 60 SPM, in the External
Multiply mode the pump counts down at 60 SPM.
27
Page 28
Batch Accumulate
The Batch Accumulate function allows you to opt to have any
extra input pulses received in the multiply mode accumulate up to
a maximum batch of 999. If Batch Accumulate is enabled and
a pulse is received during the countdown, the programmed
multiply value will be added to the current displayed value. Pulses
causing the maximum batch of 999 to be exceeded will result in
an E4 error message. When Batch Accumulate is enabled, the
LCD screen alternates between the current multiply value and
EXT
"ACC"
X
. The Batch Accumulate function is activated
in the Setup Menu (see Section 13).
12.3 Programming the mA Response
The HH9 pump accepts a 0-20 mA or 4-20 mA signal directly. The
response to this signal is fully programmable. In the mA mode, the
pump speed is determined by the programmed response curve, as
defined by points "P1" and "P2." The factory default set values for
P1 and P2 are (4 mA, 0 SPM) and (20 mA, 100 SPM) respectively.
This is illustrated in Figure 12.
While in the mA mode, the pump speed

Batch Accumulate may be enabled (1) or disabled (0)
. Use the (Up) or (Down) key to change the
selection.
34
Page 35
13.2.2 Menu Item 3: Automatic Voltage Compensation
Menu item 3 enables (1) or disables (0) automatic voltage compensation. This unique feature allows a constant power level to be
delivered to the EPU of the pump, even when the voltage of the
external power source is fluctuating. This results in smooth pump
output in spite of fluctuating voltage and prevents overheating.
Automatic voltage compensation becomes active two minutes
after power up.
13.2.3 Menu Items 4 and 5: Flow Monitoring
These menu items are not applicable to the Series HH9 metering
pump. Menu item 4 must be disabled (0).
13.2.4 Menu Item 6: Input Signal Pulse Width (Debounce)
Menu Item 6 determines the "debounce" period (pulse width) to be
applied to incoming pulse (pacing) signals. The default value is 15,
which corresponds to a debounce value of 60 mSec . Each
unit corresponds to approximately 4 mSec. This means that in order
to be recognized, an input signal must be at least 60 mSec in duration.
This setting may need to be reduced from its maximum setting for
high frequency input pulse signals such as those from a Hall Effect
flowmeter.
35
Page 36
13.2.5 Menu Items 7, 8 and 9 Activate the Integral
Blowdown Feature
These Menu Items will require additional accessories and customer
supplied components.
This Integral Blowdown feature provides cooling tower control from
your LMI microprocessor pump when used in conjunction with a
pulse output type flowmeter (batch mode) or 4-20 mA signal
(milliamp mode). These signals can then be input into the pump to
provide activation of both the pump and a customer supplied solenoid
valve.
LMI's Relay Pack, Model RP-100A, must be ordered separately
to provide power to the customer supplied solenoid.

Menu Item 7 Integral Blowdown: Select 1 = (Enable)
Menu Item 8 Solenoid ON time: Select 0 to 255 (Seconds)
Select "INT" mode and set the manual strokes per minute.
Select "EXT X" (multiply) mode (batch mode) and program
stroke count.
On receipt of a pulse from the flowmeter, the pump strokes the
programmed number of pulses. The batch value (multiply [X]
value) and manual SPM determines the length of time the pump
will be on.
On receipt of a pulse from the flowmeter, the solenoid valve is
opened. The solenoid remains open for the length of time
programmed in Menu Item 8. If another flowmeter pulse is
received before the above is completed the solenoid ON time
is extended by the time programmed in Menu Item 8.

14.0 Troubleshooting
PROBLEM POSSIBLE CAUSE
Pump Will Not Prime 1. Pump not turned on or plugged in.
2. Output dials not set properly.
3. Pump suction not flooded.
4. Air trap in suction piping.
5. Too much pressure at discharge.
Pump Loses Prime 1. Solution container ran dry.
2. Pump suction not flooded.
3. Air trap in suction piping.
SOLUTION
1. Turn on pump/plug in pump.
2. Always prime pump with speed at 80% and stroke at 100%.
3. The HH pump requires a flooded suction. Reposition the pump
accordingly.
4. Be sure the suction piping is installed so that there are no air traps
(see section 6.2).
5. Depressurize discharge piping and verify that system pressure is
within the operating pressure of your pump.
1. Refill container with solution and reprime (see Section 6.0).
2. The HH pump requires a flooded suction. Reposition the pump
accordingly.
3. Be sure the suction piping is installed so that there are no air traps
(see section 6.2).

Troubleshooting (continued)
PROBLEM POSSIBLE CAUSE
Leakage at
Piping Connection
Low Output or Failure 1. Pump’s maximum pressure rating
to Pump Against is exceeded by injection pressure.
Pressure
Failure to Run 1. Pump not turned on or plugged in.
1. Piping not sealed.
2. Worn seal rings.
3. Solution attacking Liquid Handling
Assembly material.
2. Worn Check Valves.
3. Worn Plunger Seal.
4. Incorrect stroke length.
5. Piping run on discharge may be too
long.
2. EPU failure.
3. Pulser failure.
SOLUTION
1. Apply Teflon tape to NPT threads and tighten piping (see section 6.3).
2. Replace o-rings. Spare Parts (SP-987).
3. Consult your local distributor for alternate materials.
1. Injection pressure cannot exceed pump’s maximum pressure. See
pump data plate.
2. Replace check valve components. Spare Parts (SP- 987).
3. Replace plunger seal. Spare Parts (SP- 987).
4. Check zero on pump/Re-zero pump (see Section 9.0).
5. Longer piping runs may create frictional losses sufficient to reduce
pump’s pressure rating. Consult factory for more information.
1. Turn on or plug in pump.
2. Disassemble pump and measure the resistance of the EPU across the
EPU wires (yellow). For 120v HH pump the coil resistance should be
82 ohm. For 240v HH pump resistance should be should be 330 ohm.
3. The pulser should be replaced if EPU checks out OK. Consult supplier
or factory.
Excessive Pump Output 1. Syphoning. (Pumping downhill).
2. Little or no pressure at injection point.
3. Excessive strokes per minute.
1. Move injection point to a pressurized location or install a back
pressure valve.
2. If pressure at injection point is less than 200 psi (13.8 Bar)a back
pressure valve must be installed.
3. Replace pulser or resistor. Consult factory.
