4. Hang the unit and assemble the field provided
Thread Rod, Nuts and washers on to the Brackets
as shown in Figure#5
CAUTION: Rods must be securely anchored
to the ceiling.
CONVERTING HORIZONTAL SUPPLY AIR
CONFIGURATION
The supply air location on SV Series Horizontal
units can be quickly field converted from end blow
to straight through or vice-versa. To convert the
supply air direction, follow the steps below:
1. If connected to power, shut off the unit and
disconnect switch or circuit breaker.
2. Unscrew and remove the blower access panel.
3. Disconnect the wires from the unit electrical
box to the blower motor. Note which speed
taps are wired for units with PSC or constant
torque motors.
4. Unscrew and carefully remove the blower
panel with the blower and motor attached. Be
careful not to damage the refrigerant coils or
any other internal unit components.
5. Remove the blower support brackets from the
bottom of the blower housing and relocate
them to the top of the blower housing.
6. Turn the blower panel 180° so that the blower
support brackets are now at the bottom of the
blower.
7. Insert the blower panel with the blower and
motor into the desired location. Be careful not
to damage the refrigerant coils or any other
internal unit components. Screw the panel into
place.
8. Replace the wires between the blower motor
and electrical box. Make sure to connect wires
to the proper speed taps.

9. Replace the blower access panel.
10. Reconnect power to the unit.
CONDENSATE CONNECTIONS
A drain line must be connected to the heat pump
and pitched away from the unit a minimum of 1/8"
per foot to allow the condensate to flow away from
the unit.
This connection must be in conformance with local
plumbing codes. A trap must be installed in the
condensate line to insure free condensate flow.
(Heat Pumps are not internally trapped).
A vertical air vent is sometimes required to avoid
air pockets.(See Figure #6).
Figure # 5 Condensate Drain
The depth of the trap depends on the amount of
positive or negative pressure on the drain pan. A
second trap must not be included.
The horizontal unit should be pitched
approximately 1/4" towards the drain in both
directions, to facilitate condensate removal. (See
Figure #6)
Figure # 6 Pitched Unit
DUCT SYSTEM
All SV Series models are provided with a return air
duct flange and supply air duct connections.
Refer to unit Dimensional Drawings for physical
dimensions of the collar and flange. (Pg#50)
