OUNTING AND
• The two following pictures are showing the minimum clearance needed to open the door completely.
NOTES: 1. The unit door is removable. To do so, remove the stopper (A) located on the right side
of the door hinge, then, slide the door out of its hinge. For servicing, a minimum of 15''
(381 mm) clearance from any obstruction in front of the unit is sufficient to open the door
and remove it.
2. A minimum of 8" (203 mm) clearance from any obstruction on top of the unit is required
for the ductwork radius turn.
• The joist opening needed to install the Tandem ® transition must be 9¾" (248 mm)
minimum. Also, the maximum height of the Tandem ® transition is 8¾" (222 mm).
See Tandem ® transition end view beside.
NOTES: 1. If there is not enough space to use the Tandem ® transition, the optional exterior
single hood must be installed to bring the fresh outside air to the unit.
See Section 6.8.
2. When installing a HEPA Filtration model GSFH1K, there is no Tandem ® transition.
