FAN INSTALLATION
Disconnect and lock out power supply before performing any installation work.
Working on or near energized equipment could result in death or serious injury.
NOTE:
The DVK100B dryer booster fan is designed for use in duct runs with an equivalent length
between 25 and 110 feet.
NOTE:
An auxiliary lint trap (LT100) may be installed between the dryer and the booster fan.
STEP 1. FAN LOCATION
Fan should be mounted a minimum of 15’ from the dryer outlet. Allow sufficient access to the
fan for recommended maintenance. Affix ‘Fan Location Label’ in a visible place.
STEP 2. INSTALL FAN
Attach mounting brackets to the fan housing as shown in Figure 1a or Figure
1b. Please note the airflow direction arrow located on the box cover. Secure
the fan to a support at the selected location. The fan may be mounted in any
position; however, vertical orientation is recommended to reduce condensation
build-up in the fan. The terminal box should be positioned for easy access.
STEP 3. CONNECT DUCT
Rigid duct is recommended to optimize fan performance. If using flex duct, it
should be stretched as smooth as possible. For duct runs in unheated spaces,
insulated duct is recommended to reduce the effects of condensation.
Connect duct to the inlet and outlet ends of the fan housing by means of
mounting clamps or duct tape and seal to prevent air leakage and loss of fan
performance.
TIMER INSTALLATION
STEP 4. INSTALL TIMER
The timer fits easily in a standard electrical box. If using an existing switch, remove wall plate and
disconnect switch from electrical box. Strip wire ends ½” long using strip gauge on back of timer.
Insert the stripped wire ends under the pressure plate of terminal screws on the side of timer and
screw down tightly using the screws provided.
Insert wired timer into the electrical box with “TOP” properly positioned and fasten timer to box
using the screws provided. Slip metal dial plate over threaded extension with “OFF” position facing
up. Fasten metal dial plate securely to timer with stamped nut provided.
STEP 5. CONNECT WIRING
Refer to wiring diagram below. Reattach all electrical box covers before applying power.
