Flushing Instructions

Flushing the system is required after installation or after any disassembly and

cleaning. Flushing may also be required to remove colored water from the unit.

Most filters (if installed) also require flushing prior to use – follow the

manufacturer’s recommendations.

The system may be flushed in two ways. It can be done manually by

disassembling the unit and filling and draining the unit by hand (see Cleaning the

Unit). Flushing may also be done while the unit is operating. Plug in the unit and

open a faucet closest to the unit and run the water for a minimum of 5 minutes.

External Alarm Contacts

The Hallett system provides an external “dry” contact for remote alarms or

autodialers – the word “dry” indicates no voltage present at the contact. It can be

wired normally open or normally closed. The contact is referred to as a “System

Run” condition. The status of the contact changes when the Hallett unit changes
