HWH Control Box

[jcren44]

I have a 2000 Damon Ultrasport with a HWH 210 series Joy Stick level system. My question is how to remove the control box from the drivers side floor. I need to remove the entire control box to replace the circuit board that is the box. The 2 bolts on the underside are frozen in the Hyd. valve body so in order to replace the circuit board I have to remove the complete box to be able to work on the unit. Is the control box fastened from the top inside the coach or is it fastened underneath to the floor. Underneath the coach the floor has a lot of silicone and black windshield mastic so the floor is not easy accesable. Any suggestions as to the removable process. I have talked to HWH as well as 3 differant RV mobile techs with no feasable answer as to the removable.

there are 4 screws that hold the box to the floor. remove the black knobs, and the top access cover. the screws are at the four corners.
soak the valve with a penetrating oil, and let it sit for a while. use a 7/16 socket to turn the bolts. they will turn if you put enough pressure on them.
take the not off, and drive the bolt out with a hammer. that works for me sometimes when they are stuck.
