1. Connect house sewer pipe or septic tank outlet, if required, to the

unit inlet. Make certain only household waste enters the unit (no

foundation drains, gutter drains, etc.).

2. Connect the outlet pipe to the outlet of the unit.

PIPING INSTALLATION

HIGH WATER ALARM FLOAT INSTALLATION

The Fusion

alarm panel assembly includes a high water alarm float

switch that is used to monitor the liquid level in the Fusion unit. The

switch should be tethered to one of the gray, vertical air lines in the

aeration chamber. With a 3" (76 mm) tether length, the cord should

pass through the opening in the partition wall between the aeration

and anaerobic chamber, and allow the float to hang in the outlet baffle

of the anaerobic chamber.

1. The float switch should be tethered to one of the gray, vertical pipes in

the aeration chamber. When the float is in the horizontal position,

the cord should be at least 1" (25 mm) below the top of the

partition wall opening in the anaerobic chamber baffle.

2. Place the cord into the clamp and secure to gray aeration pipe.

NOTE: Do not install the cord under the hose clamp.

3. Position the float with a 3" (76 mm) tether.
4. Tighten the hose clamp with a screwdriver. Be careful not to

overtighten as this may cause damage to the plastic clamp.

5. Make sure the float cord is not allowed to touch the excess hose

clamp band during operation as this may cause damage to the cord.

All electrical installations must follow the

National Electrical Code and/or your local/state electrical codes.

2. The blower should be directly wired into the alarm panel. The

alarm panel must be located in a dry location that is accessible

for maintenance. Please see the wiring diagram and instructions

enclosed with the alarm panel.

3. Make certain the timer within the control panel is set to the proper

time. The timer unit display should be set to 10 hours and the

timer dial needle set to 3.6 for 36 hours. This will activate an

alarm if the blower doesn't go into backwash cycle within a 36-

hour time frame.

ELECTRICAL CONNECTIONS

There are two aeration systems provided within the aeration

chamber; normal aeration and backwash. Normally valves (1 and 3)

are set at 50%. Observe the air flow on each side of the unit to verify

equal flow. If there is an obvious discrepancy in air flow between the

two sides, adjust the valves (1 and 3) so that the flow is equal.

An installation and start-up check list is furnished

with the information package in the blower box. Please use this as a

guide and fill out all sections and return to your distributor.

6. The float switch cord should be installed in electrical conduit

connecting the control panel to the Fusion

unit. The electrical

conduit must be rated for burial.

7. A ½" (13 mm) bulkhead fitting (supplied by others) should be used

to connect the electrical conduit to the Fusion

unit. A hole must be

drilled through the wall of the Fusion

unit between the red and blue

bulkhead fittings to facilitate this connection.

8. Please be certain that the bulkhead fitting for the electrical

conduit forms a watertight connection with the FRP wall of the

Fusion

unit. Silicone may be used to create a watertight seal.

9. Electrical conduit from the Fusion

unit to the alarm panel can be

buried in the same trench as the air lines.

10. The high-water alarm float switch is wired directly into the alarm

panel.
