Critical Operation Conditions of FFDE, FFDER, & FFDERA models
1. Touching of the HEPA filter will damage it, voiding the warranty on the filter. The screen is only to protect against an
accidental ‘touch’ of the filter. Never place a hand or tool on the filte . Never lie filter face flat down on a surface alwa
have filter on its side to protect from damage.
2. Prior to powering the unit, verify voltage on label and that the unit has been wired into the correct voltage. The serial
number label on the top of the unit has the required voltage.
3. To insure you order the proper replacement parts or complete unit, record the part number and serial number. This
information is located on the serial number label, located adjacent to the electrical box. If you can’t locate the Sales Order
Number, please contact Titus for this information. Once obtained, record the information for reference.
Units come set in manual mode from
the factory. Please review installation
requirements and set up with your end user
(See page 8 for complete set up instructions).

Installation
Note: Titus fan filter units are completely assembled at the factory with the exception of the optional ¼”-20 eyebolts
that are used when hanging the unit from an engineered design support system and installation of the HEPA/ULPA filters
(eyebolts not included and can be ordered separately, p/n 222449-001).
Step 1. Carefully remove the unit from the shipping carton and inspect for any damage that may have occurred during
transportation (See Figure 1).

Recommendation:
Review mode settings
at this time as specified
for installation
(see page 7 for controls).

grid. If using a flexible grid (typically supported with wires), the unit must be secured to an engineered design support
system with s-hooks and chain. Screw the four eyebolts into the nutserts on the lid assembly before lifting into an
overhead position (see Figure 2) Note: Confirm fan dimensions to match T-grid dimensions.

Note: When ordering FFDER and
FFDERA units, the HEPA filters may
be shipped separately to be installed
into units after the fan box has been
installed.

Step 3. Raise the unit and secure it into place using the chosen support system method suspended from a structural support
bracing.
Step 4. Have an electrician wire the unit to the appropriate voltage, according to the wiring diagram (page 17), and all national
and local electrical codes. All units are equipped with a three position terminal block for field onnection. Verify correct singlephase
power, before energizing units.
Step 5. Turn on the power using the two position rocker switch (ON/OFF) located on the electrical box. For FFDER and
FFDERA units, let the unit run for a few hours to purge off particulate (if filters are shipped loose) that may be adhered to
the inside of the unit before installing the filters. Do not run fan at full speed as this may cause overload condition.
Note: Your fan filter may have been shipped separate. Controls have been shipped separately.

CON4 Universal Control Card Set Up (Model ENV1028)
CON4 UNIVERSAL CONTROL CARD - PRODUCT OVERVIEW
Titus’s ENV1028 Universal Control Card provides MODBUS network and analog control capabilities to a Titus Fan Filter Unit
equipped with an electrically commutated motor. Three different control modes provide installation versatility by allowing the FFU
to be controlled via MODBUS RTU network, analog 0-10 VDC control signal, or by adjusting the onboard potentiometer. The
ENV1028 Universal Control Card is fully compatible with all of Titus’s plug & play System Control Consoles using MODBUS RTU.
Additional details of the controls modes are provided on page 8.

Manual Control Mode:
In Manual control mode, the motor speed is set using the onboard potentiometer. Onboard potentiometer rotation is CW to increase
the motor output.
Analog Control Mode:
In ANALOG control mode, the motor output is set using an external 0-10 VDC demand signal.
Network Control Mode:
In NETWORK control mode, the motor output is set using MODBUS Register 2. Motor output is specified as a value from 0 to 100
representing a percentage of motor torque output. Each ENV1028 in a MODBUS network must be set to a unique address. The address
value is set in binary using the eight DIP switches of switch bank (S2). A maximum of 200 ENV1028 devices is
recommended per local area network(LAN). If an Titus ACC Control Console is the MODBUS master, then addresses should be
assigned within the address range supported by the Control Console. Address zero should not be used as it is reserved for global
commands. Address switch settings are only checked by the ENV1028 at power-up. Power must be cycled (OFF/ON) before
affected changes take place.
