3. WARNINGS
3.1 The GI-2000 uses heating elements in it’s operation. Therefore, the unit
must always be filled with water. Elements damaged by electricity prior to
the unit being filled with water will void any said warranties.
3.2 To maintain optimum system performance and accuracy it is necessary to
remove solids accumulations in the tank on a regular basis.
4. PLUMBING INSTALLATION
4.1 INSTALLER
Installation is to be performed by a licensed and certified plumber.
4.2 LOCATION OF GRD
The Plumbing & Drainage Institute (PDI) recommends that the unit be
located within 25’ or as close as possible to the source of grease being
served. The unit may be set on the floor, partially recessed or completely
recessed below the floor. If the unit is to be recessed you must have
proper installation of the electrical hook-up, drain line and LCD control
unit.
4.3 CLEARANCE
When installing, ensure that there is 6” minimum clearance per side for
latch removal. Also provide a minimum of 24” on the outlet end in the
event that the heating elements require service. Provide adequate space
on the inlet side for installation or flow control servicing. When installing
the GI-2000 in a pit/vault provide a drain or a sump pump to prevent water
damage.
4.4 LEVELING THE UNIT
The GRD must be leveled from front to back and from side to side. The
unit must be leveled prior to calibration.
4.5 IMPORTANCE OF FLOW CONTROL FITTING
Extensive test reports conclude that both satisfactory operation and
maximum efficiency of the GI-2000 is dependant on the proper rate of flow
for the GI-2000 connected, which is accomplished by a flow control fitting.
As a result, a specially designed Josam flow control fitting with a 3”, 4”, 5”
or 6” threaded inlet and outlet connection, depending on size of unit, and a
threaded air intake is furnished with every GI 2000 at no extra cost. The
flow control must be installed to prevent overloading the trap and to
maintain maximum grease retention efficiency.

4
4.6 FLOW CONTROL LOCATION
The GI 2000 must be correctly installed with the flow control as per model
plumbing codes or the local authority having jurisdiction. The GI-2000
must have a flow control device properly vented at the inlet or in close to
proximity to the GRD inlet, thus allowing the fixtures to be plumbed and
vented as required without having any negative impact on the GRD or flow
control device whose purpose is integral to the performance of the GRD.
(See Diagram B)
4.7 FLOW CONTROL INSTALLATION
Install air intake vent from flow control to outside opening and fit elbow,
turned down; or intersect a common vent or vent stack without a trap as
permitted by local codes. Top of air intake from Flow Control is to be at
least 6” above flood rim level of the lowest fixture served. (See Diagram B)
It is recommended that the air intake be tied to the vent stack.
4.8 VENTED WASTE
The GI 2000 must have a vented waste (outlet), sized as required by local
code or local authority having jurisdiction for venting traps to retain water
seal and prevent siphoning. (See Diagram B)
4.9 ADDITIONAL REQUIREMENTS
When local codes require floor drains to flow through a GRD, the flow
control must be accessible and installed prior to the inlet of the unit.

5
DIAGRAM “B”
Locate the installation diagram which most closely suits your requirement.
Install the flow control and GI 2000 as shown.

6
5. ELECTRICAL INSTALLATION
5.1 INSTALLER
The electric service and connections to the GRD must be installed by a
licensed certified electrician.
5.2 POWER HOOKUP
WARNING! Do not apply power to the unit until the GI-2000 is completely
full of water. Install this unit as any GRD would normally be installed with
the exception to provide a 220/208VAC, single phase, Ground Fault
Circuit Interrupter (do not apply power to the unit at this point), 4 wire
connection hard wired to the main power box side of the GI-2000 per
code. The electrical installation must conform to NEMA-4 standards. The
main power wire cannot be run through a wall and must be wired to the
main breaker panel so that it can be viewed from the GI-2000 area.

WARNING! System power should be secured into the power inlet box
(access via heater element port as shown in Diagram A) in a method that
conforms to NEMA-4 standards. Wire nuts are used to connect the power
wires behind the power conduit port.
5.4 INITIAL POWER TEST
After confirming that the unit is level, fill the GI-2000 with water before
applying power to the unit. Verify with a current probe that L1 and L2 are
below 1 amp. Once confirmed, remove power from the unit.

7
5.5 CONTROL
Mount the GI-2000 controller conduit port on the GI-2000. The control
wiring conduit port is the round connector near the top of the GRD (See
Diagram A). Connect the controller cable to the control wiring conduit port.
Should additional length be required use Beldon type 8469 (9 Conductor
Cable). DO NOT exceed 200’.
5.6 RECLAIM TANK
The GI-2000 is shipped with a ¾” NPT brass outlet fitting. The fitting if
removed is a ¾” M.I.P. fitting. Maximum head is 15’ (maintain ¾”
connection). Appropriate material should be used to accommodate
possible temperatures of 140°F, as well as vibrations, when pumping.
When applications warrant a distance between the GI-2000 and the
reclaim tank, the piping must be sloped toward the reclaim tank. Heat
tracing may also be required. Venting is required.
5.7 RECLAIM TANK ALARM
A reclaim tank alarm is suggested and available as an optional feature
(See Diagram C). Contact Josam Company or your local Josam
representative for additional pumping requirements and available options.

CONTROLLER OPERATING PROCEDURES
1. WARNINGS
1.1 The GI-2000 uses electric heating elements in its operation. Therefore, the
unit must always be filled with water.
1.2 To maintain optimum system performance and accuracy it is necessary to
remove solids that have accumulated in the solids tank on a regular basis.
2. UNIT INITIALIZATION
2.1 When power is first applied to the GI-2000 the unit will beep and go
through internal diagnostics. Should any part of the diagnostics fail, the
unit will beep every 5 seconds and display a message about the failure.
The critical values of time/date, pump run time and calibration values are
stored in the unit and tested at start-up (See Section 6 of Installation
Section). Should one of the values be determined to be invalid, the unit
will wait for the user to re-enter the correct values.
