SuiteP Icons are not displaying on website - how to update/change icons for modules

We want to change icons for few in-built and custom modules. We have SuiteP theme on CRM 7.13. Could anyone help to figure out, how to view these icons. It is not showing on the below webpages. Do we have alternate way to get content code?

.suitepicon-action-above:before {
content: “\f101”;
}
