SPECIFICATIONS
THERMOSTATIC MIXING VALVE: See Installation & Maintenance Manual provided with STW-370.
INSTALLATION
Review drawing to assure proper installation. The unit should be mounted to a
structural member that will ensure structural rigidity. Connect a potable
water supply to the unit (use pipe sealant on all joints) that is a 1/2”
minimum uninterrupted source of potable water. Failure to use potable water
can result in emergency units producing impure or contaminated water causing
possible further injury.
Remove nipple from hose. Securely attach nipple to the ball valve. Secure the
Thermostatic Mixing Valve. Attach the male end of the hose to the Mixing
Valve. Attach the female end of the hose to the nipple. Tighten properly.
OPERATION
The eye/face wash is activated by pushing the push handle back 90°. The unit will operate until the push handle is manually pulled back up to the off position.

Speakman Company furnishes a testing record tag (91-0635) with each unit. On this tag the date of inspection and the inspector’s initials should be noted.
