Installation - A Series; A Series Dropper Duct Specific; Fitting A Series Optional Winter-Seal; Fitting The Rinnai A Series Cooler - Rinnai A20 Installation Manual

5.1 A SERIES DROPPER DUCT SPECIFIC

•
All Rinnai A Series units sit on a 550mm x 550mm dropper box with a 15-20mm out
turned flange.
•
Rinnai A Series units can also be installed on an existing dropper box. Ensure the
dropper box is in a sound condition and the top of the dropper box is level.
•
Rinnai A Series units may also be installed using a dropper box transition piece
(refer to Rinnai Sales Department).
•
The dropper box MUST BE positioned as per the following diagram.
•
Secure the dropper duct vertically, so the Cooler is level when placed on top of it.
•
Ensure the 3 pin power supply plug and lead, the Wall Control Loom connection
lead, and the rubber grommet, are fed to the inside of the dropper duct.
•
Cut a 43mm hole in the dropper duct below the roof line, on the left-hand-side on
the low side of the roof, to accept the wiring grommet. This will allow the 3-pin plug
and lead, and the Wall Control Loom connection lead to be withdrawn from the
dropper into the roof cavity.

5.2 FITTING A SERIES OPTIONAL WINTER-SEAL

•
For detailed instructions please refer to Rinnai A Series Winter-Seal Installation Instructions provided with the
Rinnai A Series Winter-Seal kit.
•
This Procedure MUST BE completed before the Cooler is mounted onto the dropper duct, preferably before the
Cooler is lifted up onto the roof.
•
Gently lift the unit up so that you can see the Cooler's air outlet.
•
On the Winter-Seal blades is an orange sticker indicating the bottom. This sticker should be facing down when
the cooler is in its final position.
•
Insert one end of the winter seal blades into the mounting holes provided on the base of the cooler.
•
Lock the other side into place, ensuring that they have been placed in the correct direction and that they are
both free moving.
•
Then proceed with the mounting of the cooler into the dropper duct.
The Rinnai A Series accepts the Rinnai A Series Winter-Seal.
NOTE

5.3 FITTING THE RINNAI A SERIES COOLER

•
The Rinnai A Series Cooler chassis comprises latching brackets to secure the unit to the dropper box. To assist
with connection it is important the dropper box has a 15-20mm outward turned flange.
•
In addition to the latching brackets the unit MUST BE secured to the dropper box and the cooler chassis with
screws, refer below for method:
1. Fold the end of all four latching brackets in towards the dropper box.
2. Using the 5mm hole in the bracket as a guide secure with 8g stainless steel screws.
