Introduction 1 1.0 I NTRODUCTION The Envirosource Module is an accessory to the Process Chiller, for use on systems that circulate water and/or glycol solutions that require an isolated loop from the emergency water source. With the heat exchanger providing fluid separation, the Envirosource automat...

Sequence of Operation 2 2.0 S EQUENCE OF O PERATION During normal operation, cold fluid flow from the chiller passes across the flow switch, through the heat exchanger, through the pump bypass check valve, past the supply temperature sensor and out to the load (see Figures 1 and 2 ). The standby coo...

System Components 3 3.0 S YSTEM C OMPONENTS RCM4 Monitor is configured to activate an LED and an audible alarm. The common alarm output contacts will close in response to a loss of flow or high supply fluid temperature. The silence/reset but- ton silences the alarm. The button also resets the LEDs a...
