OPERATING INSTRUCTIONS
SUPPLY TANK FOR CHEMICALS
Plastic containers must be designed and manufactured for this purpose. Your
container must be designed for whatever chemical you are using. Do not
place the container in direct sunlight. Ultraviolet (UV) rays attack many
materials which can cause them to become brittle.
OPERATION - MAINTENANCE
Once every week inspect tubing, and accessory valves and fittings. Inspect
all parts for signs of leaks, swelling, cracking, corrosion or discoloration. Also,
inspect the tubing for elasticity.
Cracking, crazing, discoloration, etc., during the first week of operation are
signs of severe chemical attack. If this occurs, immediately remove the fluid
from the injector. Determine which parts are being attacked and replace with
parts that have been manufactured using more suitable material.
The pump is designed to perform in a wide variety of installations. However,
the service life of the pump will vary, depending on many factors such as;
fluid , temperature, pressure, etc. Because of the wide variety of installations,
the pump has been factory tested for pressure and performance using water
only. Do not use chemicals if you are not satisfied they are compatible with
the pumps construction.
The pump tube assemblies are designed for maximum service life. However,
the service life can be adversely affected by the chemicals used, the amount
of back pressure, the motor RPM, and temperature.
The pump tube assemble should be inspected frequently. Replace the tube if
any cracking, leaking or loss of feed rate occurs.
THREADLESS AND THREADED INJECTORS
The most common problem is calcium and/or lime build up inside the injector,
foot valve and tubing. This is basic material and can easily be removed by
running a weak solution of muriatic acid through it. After flushing the pump
with clear water, place the injection fitting and foot valve with the tubing
attached in a container of weak (1-5) solution of commercial grade muriatic,
then run the pump for a few minutes. After flushing out the wetted parts with
clear water again, return pump to service. CAUTION do not allow acid and
chlorine products to come together. This is VERY DANGEROUS to your
health!
