If water softeners are present in the home, Zoeller Pump Company 
recommends the use of water and salt conservative models that 
are installed and operated correctly. If you have questions about 
softeners, contact the Water Quality Association at www.wqa.org. 
Contact factory for installation details.

WATER SOFTENERS

AUTHORIZED MAINTENANCE PROVIDER

Your authorized maintenance provider will perform many system 
checks and adjustments as needed during the maintenance 
inspection. Two inspections per year will be made for a total of 
four inspections during the initial service policy.  Please see the 
Operation and Maintenance section of this manual for further 
details.

Should  there  be  any  operational  deficiencies  with  your  Fusio

n

®

the maintenance provider will notify the owner in writing when 

the deficiencies will be corrected. If the maintenance provider does 
not correct the deficiencies or the service calls are not completed, 

please contact Zoeller Pump Company at 1-800-928-7867.

ALARM CONDITION

If an alarm condition occurs, please check the air intake area 
around the blower and make sure no debris blocks the blower 

intake.  Remove  the  air  filter  cap.    Remove  the  filter  and  gently 

tap against your other hand.  If it is very clogged wash it in 
warm, soapy water and dry well before replacing.  Reassemble 

filter  and  cap  on  top  of  blower.    Do  not  attempt  to  remove  the 

blower housing or any other parts from the blower. If the blower 
is operating properly, there may be a high water condition within 
the Fusion

®

. It may be necessary to discontinue water use until the 

alarm condition has been resolved. If the buzzer continues to sound 
or the red light stays on, please contact your authorized Fusion

®

 

maintenance provider. The buzzer may be silenced by toggling 
the black switch on the side of the alarm panel to “silence”. 
The red beacon light will remain on until the problem has been  
resolved.

Check the circuit breaker and make sure the blower circuit is on. 
Reset the breaker switch if it has been tripped. If it continues to 
trip or the alarm continues to remain on, contact your Fusion

®

 

maintenance provider.

 

POWER OUTAGE

Should you experience a power outage, the blower will not 
operate and air (oxygen) will not be supplied to the Fusion

®

. If 

the blower is off for more than 24 hours, the lack of fresh air will 

cause the treatment efficiency to decrease. During a power outage, 

the Fusion

®

  will  still  allow  effluent  to  flow,  and  will  not  create  a 

backup in the home. You may, however, have a pump or dose tank 
with a pump on the outlet of the Fusion

®

, which requires power to 

pump the effluent to the soil absorption field. If you have a system 

such as this, please be aware of this condition and conserve water  
accordingly.

FLOODING

If flooding of the Fusio

n

®

 occurs and the blower 

or the alarm panel is submerged, please disconnect power at 
the circuit breaker. DO NOT try to reconnect power to either the 
blower or alarm panel once it has been submerged. Immediately 
contact your authorized Fusion

®

 maintenance provider to inspect 

the Fusion

®

, the blower, and the alarm panel. Your maintenance 

provider will repair or replace the components as needed.

Fusion

®

  Series  systems  are  compact,  efficient,  and  designed  to 

be installed in a typical residential/light commercial environment. 

The final effluent leaving the system will typically be treated to the 

secondary quality strength.

EFFLUENT QUALITY

INSPECTION AND MAINTENANCE FREQUENCY

Fusion

®

 Series systems are to be inspected and maintained every 

six months under normal usage. The inspection and maintenance 
are only to be performed by personnel trained and authorized 
by  Zoeller Pump Company.  A Maintenance & Service Report 
(CL0059) is to be completed for each inspection and maintenance 
visit.

An extended maintenance policy is available for purchase from 
your authorized Fusion

®

 distributor. The extended maintenance 

policy will include the same system checks, schedule, and 
adjustments as the initial maintenance policy. Please contact your 
Fusion

®

 distributor or maintenance provider for further information 

regarding the extended maintenance policy.

EXTENDED MAINTENANCE POLICY

•  Brake fluid 

•  Paint

•  Paint thinner 

•  Gasoline

•  Solvents 

• Pesticides 

•  Herbicides 

•  Strong disinfectants 

•  Strong caustic drain 

•  Toilet tank

 

cleaners in excess 

  disinfection chemicals

•  Excess pharmeceuticals 

•  Chemicals & chemical 

waste

Not Recommended: Trash and excess food products will likely 

increase frequency of pumping.

Trash

•  Sanitary napkins and 

•  Condoms 

 

feminine products 

•  Cat litter

•  Diapers  

•  Dental floss 

 

•  Paper products such as 

•  Cigarette butts

®

 treatment process. You should always use the 

minimum quantities of these substances as recommended by the 
manufacturer.
1. Liquid laundry bleach only as needed per load
2. Liquid laundry detergents without added bleach
3. Liquid dishwashing detergents
4. Household cleaners in moderation

The Fusion

®

 system is designed to function even if wastewater 

does not enter it for extended periods of time. The power to 
the blower must remain on during this time for the system to 
function properly. Weekend use will not harm the system as long 
as the blower is on. Should seasonal use require a complete shut 
down of the property, then it is recommended that the blower 
be turned off. It is important to start up the system in advance of 
actual occupancy to allow for normal treatment to resume. Please 
contact your authorized Fusion

®

 maintenance provider for further 

information concerning shut down and startup of the Fusion

®

.  You 

may also contact your maintenance provider for the shut down 
and startup services.
