If there is the possibility of regular worship then you can install Jagannatha Deity. Otherwise don't do it. Not that there should be a repeat of the situation in Hamburg that the Deities were taken away. Unless there is solid temple arrangement I don't advise you to install the Deity. Deity installation means regular worship without fail and for good. Just like in Jagannatha Puri. That temple was established over thousand of years ago and it is still going on. Always they have prasadam ready for at least a thousand people and bhoga is offered 56 times in a day.
