CONTROL BOX MOUNTING
The VPAC/VPHP control box is factory mounted in the
front position unless otherwise specified. On larger capacity
units (19-24 only), the control box can be field modified for
left or right side applications by removing the four screws
that attach it to the front control box mounting brackets and
reattaching it to the corner posts using the same four screws.
(Figure 5). The control box can be factory mounted for left or
right side applications on the smaller capacities (9-17) but it
is not recommended for field modification at this time.

IMPORTANT: Some wire ties around the main wire
harness will need to be cut in order to move the control
box from the front position.
LEFT/RIGHT SIDE CONTROL APPLICATIONS
A. Remove applicable side panel from chassis.
B. Slide chassis into wall sleeve, assuring that wall
sleeve studs align with the holes just above the con-
denser coil.
C. Attach wall sleeve to back panel of chassis using the
two 1/4-20 nuts (see Figure 1 for detailed illustration and
Figure 3 for location of mounting holes) .
D. Replace side panel on chassis.
E. Attach applicable weather angle to chassis and wall
sleeve using one 1/4-20 nut (provided).
2. Install plenum and duct work.
3. Plug in the supplied low voltage harness and run it to
the wall thermostat as shown in the unit’s wire diagram.
4. If the unit is equipped with a drain stub in the base
pan, connect the drain stub to the building’s internal
condensate removal system.
If the unit is not equipped with a drain stub, a minimal
amount of condensate will, during the heating cycle, run
out the wall sleeve, onto the drip edge, and away from
the building when the drain pan valve opens. During the
cooling cycle, condensate will be funneled to an area near
the condensing fan and picked up by the slinger ring. The
condensate will be slung against the hot condenser coil to
evaporate. Any excess condensate due to rain or humidity
will overflow through notches in the rear of the base pan
and again run out the wall sleeve, onto the drip edge, and
out of the building.
INDOOR MOTOR SPEED TAP SELECTION
WARNING
Before accessing the control compartment, disconnect
power to the unit. Failure to do so could result in serious
injury or electrical shock.
For information on indoor motor speed tap selection,
please refer to the “Indoor Motor Speed Tap Selection
Chart” label attached to the chassis of the VPAC/VPHP
(Figure 4) .
The motor comes factory wired for the corresponding
units as described in the 230V column. Please make speed
tap changes as required by job site voltage and/or external
static pressure (e.s.p.) Speed tap changes may need to be
changed from factory settings and enviromaster interna-
tional will not be liable for any system problems that could
arise if motor speed is not changed to match application.
