1.0 Introduction
LMI is the world’s most versatile manufacturer of economical and
efficient metering pumps. This manual addresses the installation,
maintenance and troubleshooting procedures for the HH Series
manually and externally controlled pumps. LMI has a worldwide
network of stocking representatives and authorized repair centers to
give you prompt and efficient service.
The Series HH9 electronic metering pump offers an extensive range of
features, including microprocessor control for accurate and flexible
automation in response to instrument signals. The microprocessor
design employs a customized liquid crystal display (LCD) and tactile
response keypad. The "state-of-the-art" surface mount electronics are
fully encapsulated to ensure protection in its working environment. All
external inputs and outputs are opto-isolated from the microprocessor.
Please review this manual carefully. Pay particular attention
to warnings and precautions. Always follow good safety
procedures, including the use of protective clothing, eye and
face protection.
1.1 Spare Parts
LMI recommends replacing all components subject to wear and tear
on an annual basis. RPM Pro Pacs™ and spare part kits are available
from your local LMI Master Stocking Distributor. The spare parts
kit for the HH pump is SP-987.

5.0 Pre-Installation Instructions
Specific precautions should be taken when working

CAUTION
Protective Clothing

Water Pre-Prime
!
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).

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.
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.
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
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).
