VSB / VFB SERIES (Floor Exposed)
1) Mounting location must allow enough clearance to permit
removal of cabinet panels.
2) After selecting the location for the unit, remove the front
panel. The front panel must be removed on the VS or VF unit
to gain access to the coil, drain connections and electrical
junction box. To accomplish this, pull firmly on the lower
cabinet door (each side) (Figure 1) until the cabinet releases
from its friction fastener. Proceed to lift the door assembly
straight up and off the cabinet frame.

3) Position the unit in its permanent location, making sure it
is level to insure proper drainage and operation, and secure
the unit in place. Two 1/2 inch holes have been provided on
each end of the unit for securing the unit to the wall along
with two 5/16 inch holes on each end of the cabinet frame to
secure cabinet frame to wall. It is recommended that all
mounting holes be used for proper installation. (Figure 2)

4) Note the 1-1/2" x 4-1/2" indentation in the plastic drain pan
(Figure 3). This area is provided for the supply and return
runouts if they are brought up from below the pan. All piping
must be well insulated to prevent sweating. There is a 0.84"
OD condensate drain connection on the secondary drain
pan suitable to receive a standard 3/4" PVC coupling / elbow.
Remove or cover the secondary drain pan before solder-
ing the supply and return coil connections as hot solder
or the torch flame may damage the pan.
5) Solder the 5/8" coil connections in accordance with local
codes and regulations.
6) After coil connections have been made, check for leaks and
bleed the air from the system by venting each coil. (Figure 4)
