Commercial strata: appliances in CP kitchen

We are in a small commercial strata building which has a kitchen on common property and this is shared by occupants on that floor.  Nothing in our by-laws mentions kitchens or the use of electrical appliances and whitegoods etc on common property.  Someone has put a refrigerator and kettle in the shared kitchen, presumably for their own use.

In the absence of any by-laws, what can we do about this if we don’t want the refrigerator there? And who is responsible for paying for the electricity used by the refrigerator (and kettle)?

Can the strata manager send out a letter to owners and does the strata committee have the right to have the refrigerator removed — or is there some other way to resolve this?  We do not have a building manager so it’s not clear who would be responsible to act.
