Installation Instructions: Introduction and Overview

Condensate Handling

The Ducted unit has a built-in condensate pump and high water level safety switch. There are also two optional ports for gravity drainage.

The condensate pump is rated to lift water up to 27" from the point of discharge on the Ducted unit. (This number may vary.)

The Ducted unit comes with a grey connection hose and clamp. This hose is connected to the condensate discharge hose port. The other end of the hose is sized to accept 3/4 inch PVC piping.

Recommended condensate piping configurations are shown here:

12 in. below 3-5 ft. Suspending bracket Drainage hose Water drainage lifting pipe 11 in. under 6.6 in. 19.6 in. below 8.6 in. Clip

Electrical Power

Follow all local codes and regulations when installing electrical wiring.

Route required electrical power to area where the Ducted unit is to be located. Maintain at least a 10 foot separation between TV, radio, or any communication wiring and the power to the indoor unit.

14/4 non-shielded stranded copper cable should be used to make the electrical connection and communication link between indoor and outdoor units.

The wiring is connected at the indoor unit electrical terminal blocks screws 1(L1), 2(L2), 3(C) and Ground. There should be no splices in wires 1, 3, and Ground between the indoor and outdoor units, as these serve as communication signal wires and electrical power connections. Any accessory added to shut off power to the indoor units should break the Number 2 terminal only.

Optional Control Functions

The air handler supports the ability to (1) activate or deactivate auxiliary ducted heaters (by others) and to (2) activate or deactivate external air dampers (by others) for drawing in outside air.

1) Auxiliary Heater Interface Instructions

Auxiliary ducted heaters should be sized to fit the supply plenum and avoid bypass air connections. Install heater as per manufacturers recommendations. To control the operation of the auxiliary heaters with the air handler, use this procedure to interface the two systems:

• Enable the function by setting the Duct unit SW3_3 dip switch to ON.
• Route the power to the auxiliary heater through a third party 24VAC relay normally-open contacts rated for the amp draw and voltage of the heater. Interrupt power to the Relay coil with the dry contacts on the board's Green CN4 plug (Maximum 240VAC 3Amp). See the schematic below for reference.

WARNING: It is recommended to use the wired controller to set the Duct Static pressure and to ensure adequate airflow for the total heat load (see page 10 section H). Failure to do this may overheat auxiliary heaters.

NOTE: Use of a Differential Air Pressure switch for air flow proving with normally open contacts to interrupt supply power to the Auxiliary heater is recommended in the event of a fan failure.
