about loan default

Dear All I had availed of a loan by mortgaging my flat to buy some machines for my clinic. bank in question is bank of maharashtra. But due setback in business, i was not able to pay the emi's and account is almost npa. i had asked for a grace of few days from manager, who is almost coming to my clinic daily, but he says tbat if i don't pay up within a day or two,he will seal the property and start the process of recovery through DRT. What i need to know is that is the sarfesai act not applicable in this case? I am expecting some money from a source in next few days and am planning to clear the loan altogether. can the manager seal off my flat like that without applying sarfesai act? Thank you in advance.
