Limited Warranty: 

Watts Regulator Co. (the “Company”) warrants each product to be free from defects in material and workmanship under normal usage for a period of one year from the date of 

original shipment.  In the event of such defects within the warranty period, the Company will, at its option, replace or recondition the product without charge.  

THE WARRANTY SET FORTH HEREIN IS GIVEN EXPRESSLY AND IS THE ONLY WARRANTY GIVEN BY THE COMPANY WITH RESPECT TO THE PRODUCT.  THE COMPANY MAKES NO OTHER 

WARRANTIES, EXPRESS OR IMPLIED.  THE COMPANY HEREBY SPECIFICALLY DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED 

WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

The remedy described in the first paragraph of this warranty shall constitute the sole and exclusive remedy for breach of warranty, and the Company shall not be responsible for any incidental, special 

or consequential damages, including without limitation, lost profits or the cost of repairing or replacing other property which is damaged if this product does not work properly, other costs resulting 

from labor charges, delays, vandalism, negligence, fouling caused by foreign material, damage from adverse water conditions, chemical, or any other circumstances over which the Company has no 

control.  This warranty shall be invalidated by any abuse, misuse, misapplication, improper installation or improper maintenance or alteration of the product.  

Some States do not allow limitations on how long an implied warranty lasts, and some States do not allow the exclusion or limitation of incidental or consequential damages.  Therefore the above 

limitations may not apply to you.  This Limited Warranty gives you specific legal rights, and you may have other rights that vary from State to State.  You should consult applicable state laws to 

determine your rights.  

SO FAR AS IS CONSISTENT WITH APPLICABLE STATE LAW, ANY IMPLIED WARRANTIES THAT MAY NOT BE DISCLAIMED, INCLUDING THE IMPLIED WARRANTIES OF 

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF ORIGINAL SHIPMENT.

Adjust the roof drain to the height needed with the threaded rods included in the 
hardware kit. Tighten the drain at desired height.
The ductile iron dome is impact resistant and finished with standard grey epoxy 
coating.
Place the ductile iron dome over the drain body and align the holes for the screws 
on both the flashing clamp and the dome.
Place the screws into the holes and tighten until snug.

Sump Receiver Installation Instructions

Place the sump receiver over the roof opening making sure that the recessed area 
will accommodate the roof drain body while aligning with the leader pipe.
Lower the drain body into the opening and screw the deck flange into the sump 
receiver and roof.
Insert the adjustable top collar to the desired height.
 Position the roof dome over the drain and align the holes with the flashing clamp on 
the drain body.
 Place screws into the holes and tighten until dome fits snug against the drain body.

RD-300-AE Adjustable Threaded Extension

The RD-300-AE installs like the RD-300-AC except that the adjustable top collar    
is threaded instead of having a compression seal. A bead of petroleum jelly will need 
to be applied before screwing the top collar into the lower body. The threads are used  
to adjust top to desired height. Place dome onto top collar and turn slightly to lock in 
place.
"F" Deck Flange Installations and Sump Receiver instructions will also be the same. 
Use petroleum jelly for threading the top collar to the desired height.
Options for the RD-300-AE are the same.
