Electrical Protection Of The Fan Motors; Air Heat Exchanger Suction Filter Kit (Option 23B); Applicable Rules For Units Incorporated Into An Air Duct Network; Installation Of The Accessory Condensate Collection Pan - Carrier AquaSnap Touch Pilot Junior Series Installation, Operation And Maintenance Instructions

3 - INSTALLATION SPECIFICS FOR 30RQSY UNITS
3.2.2 - Fan discharge connection
A square flange is supplied mounted on the unit. An available
standard round flange can easily be installed at the fan discharge,
if the installer prefers the use of a round connection duct.
The unit is supplied with a grille on the discharge side. This grille
has to be removed before connection to the duct system.
It is advisable to make the connection to the duct system with a
flexible sleeve. If this recommendation is not observed, a lot of
vibration and noise may be transmitted to the building structure.
Unit with grille protection option
NOTE: The discharge lines must be ducted separately.
B
Fan motor access hatches (provide a 700 x 700 mm hatch) for each single and
dual duct
C
Connection bellows or sleeve
IMPORTANT: The connection of the ducts to the units must
not lead to a mechanical constraint on the decks supporting
the fans. Use bellows or flexible sleeves to connect the ducts.
At the beginning of each duct provide an access hatch with
minimum dimensions of 700 x 700 mm to allow motor
replacement or removal of the fan scroll.

3.3 - Electrical protection of the fan motors

Each motor is controlled by its own variable-speed controller.
Electrical protection is ensured by the variable-speed controller
(in case of a locked rotor or overload).
If a fan des not operate, the variable-speed controller will
automatically detect this and an alert will be sent to the Touch Pilot
Junior display. For the specific alarms list of this option, please
refer to the 30RB/RQ Touch Pilot Junior control manual.
3.4 - Air heat exchanger suction filter kit
(option 23b)
This option is available for units 30RQSY 039 to 078. The suction
duct connection is made directly to the factory-mounted sleeve
on the unit. Maintenance access to the filters is achieved by
removing the four metric screws on the side of the sleeve.
The cover panel with a manoeuvring lever can now be removed.
The filters are placed on a metal sheet that allows them to slide
in their support.
3.5 - Applicable rules for units incorporated
into an air duct network
Ensure that the suction or discharge inlets are not accidentally
obstructed by the panel positioning (e.g. low return or open doors
etc.).
3.6 - Installation of the accessory condensate
collection pan
Ref.: 30RY 900 032 EE – (30RQSY 039 to 078)
It may be necessary to remove water. Carrier can supply an
accessory condensate collection pan for installation under the
unit. The connection of this pan to the condensate collection
network can be made using a 1" gas threaded pipe.
