Installation

4308687L

Installation

The meters must be installed in-line as part of a dispense system as shown in Fig. 1. The typical installation shown

is only a guide for selecting and installing an in-line meter; it is not an actual system design. Contact your Graco dis-

tributor for assistance in designing a system to suit your needs.

Key:

A Shut-off valve

B Thermal relief valve (required; Part No. 235998) Install

downstream from the pump

C In-line filter

D In-line electronic meter

All electrical wiring must be done by a qualified elec-

trician and comply with all local codes and regula-

tions.

Do not use the IM5 In-line Electronic Meter in sys-

tems where the operating pressure exceeds the max-

imum pressure of the meter or any other component

in the system.

NOTICE

Do not use PTFE tape on threaded connections to

the meter. Such use could contribute to over-tight-

ening of the parts and cause the meter housing to

crack. Standard pipe thread compound is recom-

mended.

Grounding

Pump: follow the manufacturer’s recommendations.

Air and fluid hoses: use only grounded hoses.

Air compressor: follow manufacturer’s recommenda-

tions.

Fluid supply container: follow local code.

To maintain grounding continuity when flushing or

relieving pressure: hold metal part of the dispense

valve firmly to the side of a grounded metal pail, then

trigger the valve.

Factory Settings

The meter is factory calibrated for 10W-30 oil, and the

default unit of measurement is quarts. For other fluids

and different units of measurement, see Changing the

Measurement Units and Calibration Factor on page 8.

The equipment must be grounded to reduce the risk

of static sparking. Static sparking can cause fumes

to ignite or explode. Grounding provides an escape

wire for the electric current.

Operation

Operation

Sleep Mode

The meter automatically shuts down the display after

one minute of non-use.

Activation Mode

There are two ways to activate the display:

• Press any button on the keypad to wake up the dig-

ital display. The amount displayed is the value

stored when the meter went into sleep mode.

• Dispense fluid through the meter to wake up the

digital display. Dispensing fluid through the meter

causes the meter to count up from the last dis-

played value. See Fig. 2.

Function of TOTAL

Press and hold the TOTAL key to see the accumulated

total of fluid dispensed through the meter.

The accumulated total is shown in gallons when the unit

of measurement is set in gallons, quarts, or pints. The

accumulated total is shown in liters when the measure-

ment is set in liters. The meter accumulates a running

total of up to 99,999 gallons (or liters) dispensed before

returning to zero. See Fig. 3.

Function of RESET

Press and hold the RESET key to clear the digital dis-

play after each dispense cycle.

NOTE: Always press the RESET key to clear the digital

display before each new dispense cycle.

For Maximum Dispensing Accuracy

Set the meter to dispense in pints or quarts when dis-

pensing 1 gallon (3.8 liters) or less.

Measurement Units

Fig. 4 shows the various measurement units as they

appear on the display.

Changing the Measurement Units and

Calibration Factor

NOTE: A one liter Weights and Measures approved

container is required for calibration.

This meter is factory calibrated to dispense 10W-30

motor oil at 70_ F (21_ C) at 2.0 gpm (7.6 lpm) and is

acceptably accurate for most common fluids over a

typical temperature range. If you will use the meter to

dispense antifreeze or other approved fluids, you may

have to recalibrate it for greater accuracy.

1. Press and hold both the TOTAL and RESET but-

tons for four seconds.

The numbers on the display turn off, and the L (for

liters) and CAL (for calibration) icons turn on.

2. Set the units of measurement by repeatedly press-

ing the RESET button until the correct unit of mea-

surement is displayed. See the list below:

GAL = gallons

QTS = quarts

PTS = pints

L = liters

3. Press the TOTAL button to go to the CALIBRA-

TION menu.

NOTE: If you do not want to change the calibration

factor, press the TOTAL button again to use the

existing calibration factor and to resume normal

operation. To change the calibration factor, do

steps 4 and 5.

4. Dispense exactly one liter of fluid into a calibrated

1-liter container. For proper calibration, you must

dispense exactly 1 liter according to the markings

on the container.

NOTE: If you dispense more than 1 liter, press the

TOTAL button to exit the CALIBRATION menu.

Pressing the TOTAL button at this point does not

save the new calibration factor. You must complete

steps 1 to 5 change the calibration factor.

5. Press the RESET button to store the new calibra-

tion factor and resume normal operation.

NOTE: The number on the display is the calibration

factor number. It must be in the range of 311 to

466. The following table lists approximate calibra-

tion factors for different fluids. Your calibration

number may vary slightly due to temperature or

flow rate.
