CENTRIFUGAL PUMP
Your centrifugal pump has been quality-built and engi-
neered to give you efficient, dependable service. It is
equipped with union connectors to make installation and
future service easier.
The advanced design uses a single speed motor which
reduces operation and maintenance to simple, common-
sense procedures.
PUMP OPERATION
(Ozone, Filter, or Transfer)
WARNING: Do not touch pumps,
pump motors, water or discharge
piping when the pumps are con-
nected to electrical power. Do not
handle a pump or pump motor
with wet hands or when stand-
ing on a wet or damp surface or
in water. Never touch a pump or
discharge piping when a unit is
operating or fails to operate. Always disconnect the
pump cord (power) before handling.
1. The shaft seal depends on water for lubrication. Do
not operate the pump unless there is water. Dry run-
ning (pump not pumping water) will cause seal dam-
age and eventual pump failure.
2. The motor is equipped with an automatic reset ther-
mal protector. This means if the temperature in the
motor should rise unduly, the switch will cut off all
power before damage can be done to the motor.
When the motor has cooled sufficiently, the switch
will reset automatically and restart the motor. If the
protector trips repeatedly (cycling on protector) the
pump should be removed and checked as to the
cause of the difficulty. Low voltage, long extension
cords, clogged impeller, very low head or lift, etc.,
could cause cycling. Cycling of the protector will
cause eventual motor burnout.
PUMP MAINTENANCE
(Sump Pump)
WARNING: Before attempting to
service, disconnect power from
unit. Do not handle the pump
with wet hands or when stand-
ing on a wet or damp surface or
in water. Failure to follow pre-
cautions can result in personal
injury and /or property damage.

DAILY CHEMICAL
MAINTENANCE
Step 1. Collect a water sample from tank #1. NOTE: Be
sure that the water is circulating from the sump through
the CLP system and back to the catch basin.
Step 2. Using the test strips supplied, measure:
A. The pH.
B. The total chlorine (if using chlorine).
C. The free chlorine (if using chlorine).
D. The alkalinity (if needed).
E. The calcium hardness (if needed).
Step 3. If the pH is 6.8-7.2 go to Step 4, if not, adjust the
pH in the water being recycled between the oil water
separator and the pit to pH 6.8-7.2. Muriatic acid or liq-
uid Alum can be used to lower the pH. Soda ash (so-
dium carbonate) or caustic soda (sodium hydroxide) can
be used to raise the pH.
Adjust the pH gradually allowing complete mixing after
adding chemical. Take a new sample, read the pH and
continue to adjust gradually until the desired pH is
achieved.
Step 4. The total alkalinity should be between 50-150
ppm. If the total alkalinity is too low add sodium bicar-
bonate to raise it. If total alkalinity is too high, add muri-
atic acid to bring it within acceptable range. This will also
decrease the pH. If the pH goes below 7.0, add sodium
bicarbonate to increase the pH. This procedure may have
to be repeated several times to get the pH and a total
alkalinity into the proper range.
Step 5. The calcium hardness should not exceed 25
grains. If it is too high, some water must be removed
from the system and fresh makeup water added. Alter-
natively, an ion exchange water softener or an ionizer
may have to be added to the system to reduce and main-
tain lower calcium hardness levels.
Step 6. Free chlorine levels should be 1-2 ppm if chlo-
rine is added for additional control. A 10-50% concen-
trated liquid chlorine is available at pool supply outlets.
Household bleach can be used, but contains only 5%
chlorine. Chlorine continually dissipates and becomes
used up and the chlorine level must be adjusted daily.
Remember chlorine is most effective when the pH level
is correct (6.8-7.2).
Initially, in order to achieve proper water chemistry bal-
ance, extra time is needed. However, once achieved, it
can be easily maintained in a minimum amount of time
by daily monitoring and adjustment.
The CLP machine has an ORP/pH Controller which au-
tomatically maintains the ORP and pH levels. Total alka-
linity and hardness must be checked manually.
