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 DVK100
B
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. Consult local code
should you wish to use another type of ducting. 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.
PRESSURE SWITCH INSTALLATION
STEP 4. INSTALL PRESSURE SWITCH
For proper operation of the system, the pressure switch and probe must
be located within 25’ of the dryer and positioned between the dryer
and the fan.
IMPORTANT NOTE:
Pressure Switch Diaphragm must be in a
vertical plane as shown in Figure 2. The sample line nipple connection must
be in the ‘down’ position.
STEP 5. INSTALL PROBE
Position the probe in the duct within 36” of the pressure switch, and
greater than 16” from the fan inlet. Drill a 1/4” hole in the duct and insert
the beveled open end of the probe shaft. The arrow on the fixing plate must point in the direction
of the airflow and align parallel to the duct. Secure the probe in the duct using the two small
screws provided. Seal area around probe fixing plate to prevent air leakage. Cut tubing to required
length and attach one end of the tubing to the exposed probe post, and the other to the nipple
on the pressure switch.
