Agency Listings

	This pump is ETL listed to conform to the following: UL Standard 778 as a motor-operated water pump. CSA Standard C22.2  as process control equipment
	This pump complies with the Machinery Directive 98/37/EC, BS, EN 60204-1, Low Voltage Directive 73/23/EC BS EN  61010-1, EMC Directive 89/336/EC, BS EN 50081-1/BS EN 50082-1.
	This pump is certified to NSF/ANSI Standard 61- Drinking Water System Components – Health Effects

	Warning (Risk of electric shock)
	Caution (Refer to the user’s guide)
	Ground, Protective Conductor Terminal

ENCLOSURE RATING
NEMA 4X is Constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external formation of ice on the enclosure.
IP66 No ingress of dust; complete protection against contact. Water projected in powerful jets against the enclosure from any direction shall have no harmful effects.

INSTALLATION

	The pump should be serviced by qualified persons only. If equipment is used in a manner not specified in this manual, the protection provided by the equipment may be impaired.
	Risk of chemical overdose. Be certain the pump does not overdose chemicals during backwash and periods of no flow in the circulation system.
	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 diagrams are strictly for guideline purposes only. Always consult an expert before installing a metering pump on specialized systems.  The metering pump should be serviced by qualified persons only.
	Be sure that installation does not constitute a cross-connection with the drinking water supply. Check your local plumbing codes.
	The pump should be supplied by an isolating transformer or RCD (operating current less or equal 30 mA).

Mounting Location

1. Choose an area located near the chemical supply tank, chemical injection point, and electrical supply. Also, choose an area where the pump can be easily serviced.
2. Finding a secure surface and using the provided mounting hardware, mount the pump close to the injection point. Keep the inlet (suction) and outlet (discharge) tubing as short as possible. Longer discharge tubing increases back pressure at pump head.
   NOTE: Mounting the pump lower than the chemical container will gravity-feed chemicals into it. This “flooded suction” installation will reduce output error due to increased suction lift. A shut-off valve, pinch-clamp, or other means to halt gravity feed to the pump must be installed during servicing.
   NOTE: Install a backflow prevention check valve at the discharge side of the pump to prevent the system fluid from flowing back through the pump during pump maintenance.
   NOTE: It is recommended to have a pressure relief valve at the discharge side of the of the pump.

5.2 Wall Mounting

1. Using the provided #10 self-tapping screws, mount the bracket to a secure wall that is located where it can be easily serviced.
   
2. Lower the pump so that the tab on the wall mount is inserted into the slot located on the back of the pump. The pump will now be secured to the wall mount bracket.

POWER CONNECTIONS

	Risk of electric shock – cord-connected models are supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle.
	Electrical connections and grounding (earthing) must conform to local wiring codes.
	Ensure to connect the pump to the proper supply voltage. Using the incorrect voltage will damage the pump and may result in injury. The voltage requirements are printed on the pump serial label.

• Use the voltage for which the power cord is rated.
• Do not strap together control (input/output) cables and power cables.
• When there is a power interruption, the pump, which has an auto-restart feature, will restore the pump to the operating state it was in when the power was lost.
• POWER: 115V60Hz (0.6A max.), 220V50Hz (0.3A max.), 230V60Hz (0.3A max.), 230V50Hz (0.3A max.), 240V50Hz (0.3A max.)
  NOTE: Contact a licensed electrician when there is doubt regarding the electrical installation.

OUTPUT ADJUSTMENT

The speed of the pumping mechanism is adjustable from 0.01 to 100 % motor speed (0.01 RPM to 100 RPM).

DFD (Diaphragm Failure Detection)

The MD1 is equipped with a Diaphragm Failure Detection System which is designed to stop the pump and provide an output alarm in the event the diaphragm should rupture and  chemical enters the pump head.
This system is capable of detecting the presence of a large number of chemicals including Sodium Hypochlorite (Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide, and many others. The system will not be triggered by water (rain, condensation, etc.) or lubricants.
If the system has detected chemicals, the pump diaphragm must be replaced and the pump head must be thoroughly cleaned.
Failure to clean the pump head will void the warranty.
If a DFD alarm occurs, the pump will stop, close an alarm output, and the screen will flash DFD with an alarm icon.

Pump Maintenance

	Prior to service, pump clean water through the pump and suction/discharge line to remove chemicals.
	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.

12.1 Routine Inspection and Maintenance
The pump requires very little maintenance. However, the pump and all accessories should be checked weekly. This is especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking, discoloration or corrosion. Replace worn or damaged components immediately.
Cracking, crazing, and discoloration during the first week of operation are signs of a severe chemical attack. If this occurs, immediately remove the chemical from the pump. Determine which parts are being attacked and replace them with parts that have been manufactured using more suitable materials. The manufacturer does not assume responsibility for damage to the pump that has been caused by a chemical attack.

12.2 Cleaning Pump
The pump will require occasional cleaning, especially Injection fitting, Foot Valve / Strainer, and pump head valves.
The frequency will depend on the type and severity of the service.
Inspect and replace pump head valves as required.
Periodically clean injection/check valve assembly, especially when injecting fluids that calcify such as sodium hypochlorite. These lime deposits and other build-ups can clog fitting, increase back pressure and interfere with check valve operation.
Periodically clean suction strainer.
Periodically inspect pump housing (enclosure) for the chemical attack. Protect pump housing from continuous exposure to chemicals, such as drips or fumes from surrounding equipment and plumbing.

12.3 Replacing the Pump Diaphragm
When changing the diaphragm, the pump head chamber and pump head cover should be wiped free of any dirt and debris. The pump stroke must be FORWARD when installing the diaphragm, and BACK when installing and tightening the pump head.
When replacing the pump diaphragm, note the order of parts per the illustration below:
