Installation Instructions; Blower With Cased Evaporator Coil Installation; Upflow Installation; Counterflow Installation - Goodman MBVC 1 Series Installation Instructions Manual

• The factory recommends insulating the duct running
through any unconditioned spaces.
To reduce operating sound and vibration transmission use flexible
canvas duct connections at the cabinet.

Installation Instructions

Blower with Cased Evaporator Coil Installation

Secure the coil and blower together with the two connector plates
and screws supplied in the blower bag assembly. Use one connec-
tor plate and six screws on each side of the unit.
If accessory electric heat is to be added, install now per the in-
structions shipped with the heater kit.
Figure 2 - Upflow Application

Upflow Installation

For upflow installations, the blower cabinet must sit on top of the
coil cabinet (Figure 2).
NOTE: All panels should be in place before installing the cabinet.
1. Place the blower and coil cabinet assembly upright on
the return duct or duct opening. Ensure that there is
ample support for the cabinet assembly and all attached
ductwork.
2. Connect refrigerant and condensate drain connections
per the evaporator coil installation instructions. Ensure
refrigerant and drain lines do not interfere with service
access to the unit.
3. Attach supply ductwork. Seal connections between unit
and ductwork as required to reduce/eliminate air leakage.
4. Make electrical connections as specified in Electrical
Connections section of this manual.

Counterflow Installation

For counterflow installations, the evaporator coil cabinet must sit
on top of the blower cabinet (Figure 3). NOTE: All panels should
be in place when installing the unit.
NOTE: Supply ductwork for counterflow applications, must be Class I.
However, if combustible ductwork is used, sheet metal protection
is required.
Figure 3 - Counterflow Application
1. Place the blower and coil cabinet assembly supply outlet
on the supply duct or duct opening. Ensure there is ample
support for the unit and all attached ductwork.
2. Connect refrigerant and condensate drain connections
per the evaporator coil installation instructions. Ensure
refrigerant and drain lines do not interfere with service
access to the unit.
3. Attach return ductwork. Seal connections between unit and
ductwork as required to reduce/eliminate air leakage.
4. Make electrical connections as specified in Electrical
Connections section of this manual.

Horizontal Installation

For horizontal installations, the coil cabinet must be upstream of
the blower cabinet (Figures 4 and 5). NOTE: All panels should be
in place when installing the unit.
1. Set the unit near its final installation place. The unit must
be supported along the entire length of the unit. Rubber
isolation pads may be used to reduce sound and vibration
transmission. Ensure there is ample support for the unit
and all attached ductwork.
NOTE: Unit must be mounted with access panel facing the front
as shown in following diagrams.
2. If installed above a finished ceiling or living space, be sure
to put a secondary drain pan under the entire unit, and pipe
the drain separately from the main condensate drain.
3. Connect refrigerant and condensate drain connections per
the coil section installation instructions. Ensure refrigerant
and drain lines do not interfere with service access to the
unit.
