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 30RQS Series Installation, Operation And Maintenance Instructions

NOTE: The discharge lines must be ducted separately.
Fan motor access hatches (provide a 700 x 700 mm hatch) for each single and
dual duct
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.
The fan protection grilles can be removed to increase the
available pressure.
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.
