IV. Installation
A. Location
Select a mounting location convenient to the chemical supply as well as a source of power for the pump. Do not install the pump in a location where the ambient temperature exceeds 120 degrees F (50°C). Higher temperatures will affect the output as well as the useful life of the pump. While the AromaMist pump is suitable for most outdoor installations, do not use the standard poly tubing in direct sunlight. If you must mount pump in direct sunlight or under bright fluorescent lights, consult your distributor or the factory.
B. Electrical
1. AromaMist pump models AI-1 and AI-1-4 are 120V AC pumps and have a voltage regulated internal power supply capable of operating in the range of approximately 95V to 135V AC. Use a power supply of 100 to 120V AC for best results. The 3-wire grounding plug must be used in a 3-wire wall plug (see typical steam solenoid electrical hook up below).
CAUTION: Never remove ground wire from plug.
2. AromaMist pump models AI-2 and AI-2-4 are 240V AC pumps and have a voltage regulated internal power supply capable of operating in the range of approximately 195V to 260V AC. Use a power supply of 210 to 250V AC for best results. Pump is supplied without a country specific plug unless otherwise stated (see typical steam solenoid electrical hook up below).
Page 5

C. Plumbing

1. Piping Connections
The AromaMist pump uses carefully matched components to achieve a predictable metering output. This predictability can only be maintained if all fitting sizes remain unaltered. Do not attempt to reduce tubing size. All tubing connections should be double-checked to insure against leakage. If hazardous chemicals are being pumped, use shielding around discharge tubing.

NOTE:

When cutting lengths of tubing for your installation, ensure a clean, square cut. Use short lengths of tubing and as few connections as possible.

2. Tubing Nuts
Do not over tighten the tubing connectors. Tighten the fittings no more than 1/4 turn after the fitting contacts the seal. Hand tighten only. Do not use a wrench or pliers as they may damage the fittings. Do not use Teflon tape except on NPT fittings. Be sure to observe applicable local plumbing codes.

WARNING: Clear flexible tubing is not intended for pressurized use. 3. Tubing Connections

Page 6

4. Suction Lift vs. Flooded Suction Applications (models AI-1 and AI-2 only) Suction Lift Installation Mount the AromaMist pump on the top of or above a chemical tank, not to exceed 5 feet from pump to bottom of tank. Flooded Suction This installation is recommended wherever possible. Priming is easier and loss of prime is reduced.
5. Foot Valve Installation (models AI-1 and AI-2 only) A weight is provided to hold the tubing and foot valve in a vertical position at the bottom of the tank. Do not allow the foot valve to lie horizontally in the chemical container. This defeats the action of the valve and can cause the pump to lose prime. Keep suction tubing reasonably short and avoid high spots or bends.
Page 7

6. Wall Mounting
The fluid end portion (head assembly) of the pump is set up to accommodate mounting of the pump to the chemical container, either as a flooded suction or a suction lift. The pump head must be kept in a vertical position for proper operation. The head can be removed and rotated 90° if needed to keep the inlet and outlet valves in a vertical position.
7. Injection Valve Installation The injection valve is designed to prevent a back flow and to inject chemical into the line. To work properly, this valve must NOT be mounted above the steam line or facing downward into the steam line. One end of the injection valve is 1/2″ MNPT. Install this end into the piping system. Use Teflon tape on this fitting only. Connect the pump’s discharge tubing to the opposite end of the injector. Do not use Teflon tape or joint compound on this fitting. Connect tubing between this fitting and the pump discharge fitting at the pump.
8. Priming/Bleed Valve Connection (models AI-1 and AI-2 only) Connect the clear poly tubing to the outlet of the bleed or priming valve. Position the free end of this tube in the chemical container, above the fluid level.

Page 10

B. Priming the Pump
1.Pump Priming Mode Plug in and/or power up the pump at the switch. If pump is in stroke mode, (pump LCD display reads “strokes/min”) press the enter (ENTER) key to initiate the pump priming mode. If pump is in delay mode, (pump LCD display reads “start in: xxx min xx sec”) power down the pump. With pump off and while pressing on the down arrow () key, power on the pump at the switch to initiate pump stroke mode. Press the enter (ENTER) key to initiate the pump priming mode. Note: Prime mode (125 strokes/minute) will always automatically default to stroke mode after 1 minute. If additional priming time is desired, press the enter (ENTER) key during the stroke mode to initiate further priming. Repeat as necessary until pump priming is complete (see step 2). To exit the pump priming mode, press the enter (ENTER) key to return to the pump stroke mode.
2.Priming/Bleed Valve With pump in priming mode, if fluid begins moving up suction line without hesitation, bleed valve adjustment is not required. If fluid is not moving up suction line, open bleed valve approximately one (1) turn or until fluid begins to move. When fluid level reaches the pump head assembly, close bleed valve allowing fluid to flow through pump head and up to the injector spray head assembly. Once priming is completed, press the enter (ENTER) key to return the pump stroke mode. NOTE: Do not over-tighten bleed valve as damage may occur.

C. Adjusting Pump Feed Rate/Strokes per Minute
The AromaMist pump can be adjusted to deliver the exact fluid feed rate desired. The number of pulses/strokes per minute can be easily adjusted and displayed on the pump LCD display. Feed rate can be adjusted from 1 to 99 strokes per minute. Depending on application, desired feed rate will vary. Starting with the factory pre-set 10 strokes per minute, adjust the fluid feed rate up or down depending on your particular application.
To adjust the feed rate: · While in the pump stroke mode, press the menu (MENU) button. The LCD display will read “Strokes = 10/min”
· With the blinking cursor on the XX, (the number field) press the up arrow () to increase the strokes/minute or press the down arrow () to decrease the strokes/minute.
· Press the menu (MENU) button to exit the feed rate adjustment mode.
D. Adjusting the “Limit To”
If the AromaMist pump strokes continuously for more than 60 minutes, the pump will go into an Alarm mode and stop stroking. Further investigation should be made as to why the electrical source kept the pump in a stroke mode for a continuous 60 minutes.
If the AromaMist pump is in Alarm mode, turn the power switch to the off mode and then power it on again to reset the Alarm mode. The “Limit To” factory default setting is 60 minutes and can be adjusted from 0 to 240 minutes (4 hours). A setting of 0 turns the “Limit To” feature off.
CAUTION: It is not recommended to exceed the factory 60 minute default setting.
To adjust the “Limit To” setting:
· Press the menu (MENU) button.
· Press the enter (ENTER) button to skip over “strokes = xx/min”.

· Press menu (MENU) to exit “Limit To” adjustment mode
E. Adjusting the “On Delay”
On cold equipment start-up, the AromaMist pump is programmed to delay for 20 minutes before it begins to pump fluid. This “On Delay” allows for the time it takes steam to be generated before fluid is introduced into the steam line. When the pump is in the “On Delay” mode, the LCD display will read “start in: xxx min xx sec”, and the keypad is disabled.
You may override the “On Delay” mode by powering the pump on at the switch while simultaneously pressing the down arrow () key.
Note: The “On Delay” feature is designed to prevent fluid waste.
Adjustable from 0 – 120 minutes, the “On Delay” should be set for one minute less than the amount of time it takes your equipment to generate steam on a cold start-up. If you believe an adjustment must be made for your application, please consult the factory prior to proceeding.
To adjust the “On Delay” setting:
· Press the menu (MENU) button
· Press the enter (ENTER) button to skip through the Strokes = x/ min
· Press the enter (ENTER) button to skip through the Limit To XX Min
· When the LCD displays “On xxx min xx sec” use the up arrow () and down arrow () buttons to adjust the desired on delay.
· Press menu (MENU) to exit “On Delay” adjustment mode.
Page 13

F. Adjusting the “Off Delay”
The AromaMist pump allows for an “Off Delay” adjustment in order to determine when the pump startup should be delayed. After initial cold start-up, and during operation, there will not be an “On Delay” occurrence unless the AromaMist Pump has been powered off for the amount of time selected in the “Off Delay” adjustment mode. The factory default is set for 4 hours 40 minutes. The “Off Delay” is adjustable from 0-8 hours (480 minutes). Note: “Off Delay” settings need only be adjusted if during any normal operating day, the AromaMist Pump will NOT be off for more than 4 hours (240 minutes). If you believe an adjustment must be made for your application, please consult the factory prior to proceeding.
To adjust the “Off Delay” setting: · Press the menu (MENU) button · Press the enter (ENTER) button to skip through the Strokes=xx min · Press the enter (ENTER) button to skip through the Limit To XX Min · Press the enter (ENTER) button to skip through the “On xxx min xx sec” · When the LCD displays “Off x hr xx min” then use the up arrow () and down arrow () buttons to adjust the time accordingly. · Press menu (MENU) to exit the “Off Delay” adjustment mode.

VII. Troubleshooting

Problem
Pump does not achieve or maintain prime
Insufficient fluid

Cause

Remedy

Air trapped in suction line

Straighten suction line so as to eliminate high spots.

Foot valve contaminated Inspect foot valve screen and assure that foot

or improperly installed

valve is in a vertical position below fluid level.

Excessive lift

Maximum suction lift is 5 feet with water or fluids of similar specific gravity; less with heavier liquids such as acids. Mount pump in a lower position relative to the chemical container.

Suction fittings not properly tightened

Check fittings. Overtightening may cause
restriction. Conversely, if any leakage occurs, pump will suck air and fail to prime.

Worn or contaminated check valves

Inspect check valves in fluid end for cleanliness. Clean or replace as necessary.

Kink or pinch in suction tube

Inspect suction tube through its full length to assure that there are no kinks or other restrictions.

Move any objects or equipment which impinges upon suction tube or reroute as required to assure a smooth transition from foot valve to pump.

Low chemical level

Check fluid level in chemical supply tank.

Worn or contaminated check valves

Inspect, clean or replace as necessary.

Obstruction in suction line Check suction line for obstructions, clogging, kinks or pinch points.

Clogged foot valve screen

Clean or replace foot valve screen.

Diaphragm worn or torn

Replace diaphragm, making sure that it is screwed on fully to shoulder of shaft.

Electronic failure

Consult dealer or factory.

Page 19

Problem
Excessive fluid
Pump will not pump
Pump will not run or not plugged in Excessive noise

Cause

Remedy

Failure or lack of antisiphon valve

Inspect or add anti-siphon valve. This is caused when system is in a vacuum condition or valve in delivery applications with flooded suction which feeds systems at very low pressures.

Excessive stroke rate

Lower the stroke rate if adjustable on your pump.

Improper stroke length

Consult dealer or factory.

System pressure too high Check system pressure to assure that it is within system rated parameters of the pressure.

Diaphragm improperly installed

Make sure that diaphragm is screwed fully onto shaft.

Check valves worn or clogged

Clean or replace as required.

Pump not turned on or not plugged in

Check outlet with meter to assure that 95-135 VAC is present on 120V systems, 195-260 VAC is present on 240V systems and that power supply cord is in good condition and plugged in.

Electronic failure

Consult dealer or factory.

Pump not primed

Prime pump.

No output pressure

Add an anti-siphon valve to provide 25 PSI restriction on pump discharge.
