The HRV 1500 SFD and HRV 1500 SFDE are designed to be
serviceable from either side. If access to the unit will only
be available from one side, the unit must be set up accord-
ingly. The unit is factory shipped to be serviced from the
front.  (Blowers on the right when facing the unit. If servic-
ing is only accessible from the other side follow the proce-
dure below.
1. The Ebox must be removed from the front brackets and

mounted on the rear brackets provided on the other side
of the unit.

2. The filter divider panels must be removed and placed in

the unit so they can be removed from the opposite side.

3. The lower blower divider panel must be removed and

mounted in the unit from the other side.

Each panel on the unit can be removed by removing the
two bolts on the bottom.

Servicing is easiest by removing the side panels on both
sides to gain access to either side of the unit.
