MAINTENANCE
FUSIBLE LINKS
The date stamped into a fusible link during manufacturing is intended as “Inventory Control Identification”. The date however, in no
way limits or suggests when the fusible link can be used. It is important to understand that fusible links, having never being used,
have no shelf life. Fusible links only begin to degrade once they are installed into a system and exposed to the hazard. From the
installed date, the life of the fusible links is not to exceed six (6) months. Replacement is required as the links may not be reused.
The code requires used links to be destroyed after use. Refer to NFPA17A 7.3.4 for additional information.
NOTE:
The pressure
gauge should be
inspected for the
proper pressure levels
prior to each use.
HOW THE D1000 WORKS
The D1000 is a fully integrated fire suppression range hood system. It functions as a standard ventilation range hood with the
capability to suppress fires on the cooktop. The D1000 is designed for use over 30”and 36” residential ranges, in “not for profit”
cooking environments. The D1000 uses a mechanical commercial style automatic fire suppression system.
A PLC provides an internal alarm connection for up to two external alarms that may go to a local alarm panel and/or
remote location; i.e. the local fire department.
The unit is powered by a standard 120 VAC/60Hz/15A/ single phase circuit.
The thermostat switches react to preset points to turn the fan ON to dissipate heat and prevent a fire event.
If a fire occurs, the fusible links will melt, causing the hood’s system to release the fire suppression (Amerex 660)
mechanically fail safe process
WARNING: Each fusible link must be replaced after six months of use.
WARNING: Safety glasses and gloves must be worn whenever service operations are performed.
The hood should be put in maintenance mode (see page 20) prior to service.
