Spectrometer Installation
Caution Water Pressure – Leaking hose fittings or burst water hoses
If the water inlet pressure is too high, hose fittings may leak or hoses may even
burst.
 For reliable and safe operation, you must install the pressure relief valve kit
B313-0124 in the water supply line.
The hoses provided in the kit are fitted with automatic connectors that incorporate
stop valves; these valves prevent water from running out when the hoses are dis-
connected. The hoses are marked with the direction of the water flow.
