TRANSITIONING TO 8-IN. DUCTS
If using 8-in. ducts, install 6-in. to 8-in. transitions on the ports, and
secure using duct tape only. If rigid ducting is used, install a 12-in.
section of flexible duct between the transition and the rigid ducting
(Fig. 12).
RIGID DUCTS
To prevent potential water leakage in cold side rigid ducting insulation,
seal all rigid ducting joints with duct tape. To avoid transmission of
vibrations, always use a 12-inch section of flexible duct to connect rigid
ducts to the unit. To connect insulated rigid ducts to the unit (cold side)
using insulated flexible ducts, follow instructions per (INSTALLING
THE EXTERIOR HOODS on p7). To connect regular rigid ducts (warm
side) to the unit using non-insulated flexible ducts, use a tie wrap.
NOTE: We recommend to use 8" ducting instead of 6" ducting if the
required airflow is over 200 cfm and long runs of ducting or high
quantity of elbows are used. This will prevent having too high static
pressure in the ducting.
DUCTS CONNECTION
IMPORTANT: Make sure to connect ducting as illustrated below to get
airflows reading accuracy. Correct installation will also allow proper
drainage of water that may accumulate in ducting.

CONNECTIONS
ELECTRICAL CONNECTION TO OPTIONAL MAIN
WALL CONTROL
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
- Ducting must not be too crushed. Otherwise, airflows reading
accuracy will be affected.
- Insulated ducts must have the same diameter as the ports to
ensure proper drainage of water that may accumulate in ducts.
WARNING
!
ELECTRIC SHOCK HAZARD
Failure to follow this warning could result in personal injury, death, or
equipment damage.
Always disconnect the unit before making any connections. Failure to
cut power could result in electrical shock or damage to the wall control
or electronic module inside the unit.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
- Never install more than one optional main wall control per unit.
- Make sure the wires do not short-circuit between themselves or
by touching any other components on the wall control.
- Avoid poor wiring connections.
- To reduce the risk of electrical interference (noise), do not run
wall control wiring next to control contactors or near light
dimming circuits, electrical motors, dwelling/building power or
lighting wiring or power distribution panel.
