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

Installation (Examples only)
Note: In those areas where these types of installations are approved, it is subject
to the approval of the local or state code inspection authority.
Applications
Series 3 ⁄
8
" 7 or LF7 is especially recommended for shampoo sink or similar appli-
cations requiring 3 ⁄
8
" female connection for convenient attachment.
It is also suited for other continuous or intermittent pressure type installations
where water distribution piping flows to potentially contaminated containers,
equipment or sinks. In the event of negative supply pressures, such contaminated
fluids must not be allowed to backflow to the potable water supply source by
backsiphonage or other cause.
Installation
Before installing, flush out pipe lines to remove scale and other foreign matter. The
valve can be installed horizontally or vertically. Install the valve in the line with the
arrow on valve body pointing in the direction of flow. Teflon ® tape is recommended
for the pipe threads. To maintain the valve discs in a clean operating condition, we
strongly recommend a pipe line strainer (Watts model 27) be installed in the supply
line before the Series 3 ⁄
