Precautions - Milton Roy LMI P1 Basic Manual

The pump described here may be used for the dosing of liquid products in connection with the applications set out in this
manual.
The following precautions should be taken when working with LMI metering pumps. Please read this section carefully prior to
installation.
Storage precautions
- Storage period of less than six months:
The product should preferably be stored in its original packing and be protected from bad weather.
- Storage period of more than six months:
Store the pump in its original packing. It should be stored covered by a heat-sealing plastic cover and desiccant bags
should be used (quantity dependent on volume and planned storage period). Store away from the influence of bad
weather.
Protective Clothing
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.
Water Pre-Prime
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, valves, seal rings, balls and Liquifram
(diaphragm). 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.)
Solution Compatibility
Determine if the materials of construction included in the liquid handling portion of your pump are adequate for the
solution (chemical) to be pumped. Always refer to the solution supplier and the LMI Chemical Resistance Chart for
compatibility of your specific LMI metering pump. Contact your local MRE distributor for further information.
Tubing Connections
Inlet and outlet tubing or pipe sizes must not be reduced. Outlet tubing size must not be increased. Make certain that
any tubing is SECURELY ATTACHED to fittings prior to start-up (see Section ., Tubing Connections). ALWAYS use
LMI supplied tubing with your pump, as the tubing is specifically designed for use with the pump fittings. It is
recommended that all tubing be shielded and secure to prevent possible injury in case of rupture or accidental damage.
If tubing is exposed to sunlight, black UV resistant tubing should be installed. Check tubing frequently for cracks and
replace as necessary.
Vinyl Tubing
Your carton may contain a roll of clear vinyl tubing; this is only for connection to the return line of the FastPrime
and must not be used as discharge tubing.
Connectors
All connectors shall be tightened by hand. An additional turn of 1/8 to 1/4 might be necessary to ensure tightness. Any
excessive tightening or using a toolmight damage the connecting device and the seals or the liquid end.
All LMI pumps have straight screw machine threads on the head and fittings and are sealed by the O-rings. DO NOT
use Teflon tape or pipe dope to seal threads. Teflon
®
Injection Check Valve, the stainless steel liquid end connections, or if piping is directly connected to the pipe threads of
the suction or discharge fittings.
Installation
Always comply with local regulations and requirements. Always adhere to your local plumbing codes and requirements.
Be sure installation does not constitute a cross connection. Check local plumbing codes for guidelines. Milton Roy

Back Pressure/Anti-syphon valve
If you are pumping downhill or into low or no pressure system, a back pressure/antisyphon device such as LMI's Four-
Function Valve should be installed to prevent over pumping or siphoning. Contact your distributor for further
information..
Electrical Connections
WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a properly grounded
grounding-type receptacle with ratings conforming to the data on the pump nameplate.. Do not use adapters! All wiring
must conform to local electrical codes. If the supply cord is damaged, it must be replaced by the manufacturer, stocking
distributor, or authorized repair centre in order to avoid a hazard..
Environment
The ambient temperature must be less than 50°C. Avoid direct exposure to sunlight. The pump must be accessible and
situated in a ventilated room.
