Factory Options

The Factory Options screen is used to configure the bath, purge, defrost and heat

options.

∧ Factory options

Bath Option YES

Purge Option YES

Hot Gas Defrost YES

Heat Option No

ZL Defrost No

The optional Heat and Purge components are enabled when set to YES. This results

in changes to the Main Menu and Synoptic screens, adding control of these features.

Note: The Heat and Purge options require additional factory-installed components to function.

If either option is purchased, the function will be enabled at the factory. If you are unsure

whether you purchased the Heat or Purge option, contact SP Industries.

The Hot Gas Defrost option uses a hot gas refrigeration loop to reduce defrost time.

Setting the Hot Gas Defrost field to YES enables the hot gas defrost.
