NOTE:
BE SURE TO KEEP THE STW-370 AS CLOSE TO THE
CENTER OF THE FAUCET BODY AS POSSIBLE.
ADAPTER (3)
TEE W/CHECK
VALVES (2)
The combination eyewash-laboratory faucet shall have dual internal waterways that allow the faucet and
eyewash components to be operated individually or simultaneously. The eyewash shall be capable of
delivering tepid or cold water while the faucet is operated at a user determined temperature.
The faucet shall have lead free brass construction and be operated via 1/4 turn ceramic disc cartridges.
The spout shall be user configured as either swivel or rigid and the faucet flow rate shall be a maximum of
1.5 gpm Product shall accommodate an 8”-16” spread.
The eyewash shall feature aerated sprays with automatic flow controls, flip top covers and have a minimum
flow rate of 2.1 GPM @ 30 PSI. Eyewash shall be activated via a lift lever. Product shall be compliant with
ANSI/ISEA Z358.1, ASME A112.18.1-2011/CSA B125.1-11 and CA AB1953.
The faucet spout was designed to swivel from left to right. If a
non-swivel spout is preferred, remove top cover from body. Next,
remove allen head set screw from position “1” as seen below.
Center the spout between the handles and install the previously
removed set screw into position “2” and tighten (DO NOT
OVERTIGHTEN). Replace cap.
Lift eyewash handle to activate the eyewash and test for proper
operation. See chart and notes at right.

NOTE: If plume heights are low, check to ensure that your supply valves are
fully open. If there is a noticeable height difference between the two plumes,
remove the aerators and flow controls and remove any debris that would
inhibit the flow of water.
NOTE: Before testing, you must remove tape from Eyewash Caps.
