BRANCH DUCT (see page 57 for kit details)
This kit provides an air discharge into an adjacent room
The branch duct MUST be taken from the access point on the chassis, (kit details shown on page 57).
Ductwork should be fully insulated and supported throughout its length.
The graphs below show the airflow passed by a single branch duct: it can be seen that 3-way discharge on the unit, by
blanking off the fascia side to which the branch duct has been connected, will enhance the branch airflow.
DISCHARGE BLANKING
On cool only air conditioners, and heat pump systems without boost heaters, it is possible to blank off the airflow of any one
of the four sides (on latest models with kit 55500316).
This will assist applications such as L shaped rooms etc..
IMPORTANT NOTE:
On units fitted with electric heating, DO NOT
blank off any side as this will
restrict airflow over the heating elements. causing them to overheat.
1. Fit the six foam blanking pieces prior to refitting the fascia.
2. Select the side to be blocked.
3. Wedge the six foam blanking pieces into the relevant air discharge slots of the chassis ensuring that the upper surface
is 50mm below the top of the outer side wall of the chassis.
