III. INSTALLATION (continued)
III. i - OPTIONAL UTILITY BASE (cont'd):
3. Assemble four 1/2 –13 bolts and lockwashers
through holes in utility base and into threaded
holes in bottom of unit where legs or casters
would be installed.
4. Place rear cover on back of utility base so D-slot
captures the groove of the strain relief. Attach
rear cover with six 8 – 18 self-tapping screws. If
floor receptacle is provided underneath utility
base for unit to plug into, strain relief will not be
used and rear cover should be installed up-side-
down so D-slot is covered.
5. Install front grill on front of stacking base with
eight 8 – 18 self-tapping screws.
If your unit comes with a utility base, we recommend
securing the base to the floor. Place the unit in its
final installed position, then apply a bead of NSF
approved silicone sealant around the bottom.
III. j - OPTIONAL STACKING KIT:
Models UHT27 and ULT27 only have the option of
a stacking kit, in which no more than two (2) units
can be stacked one on top of the other.
1. Install legs, casters or utility base on bottom unit
following instructions elsewhere in this manual.
Place bottom unit near final installed location
leaving access to rear for further assembly.
2. Place stacking base on top of bottom unit. NOTE:
The front of the stacking base must be oriented
towards the front.
3. Assemble two 1/4 – 20 x 5/8" screws through front
mounting flange of stacking base into the
threaded holes in the front of the top edge of the
bottom unit. Assemble five 10 – 16 x 1/2" screws
through rear flange of the stacking base into the
upper rear of bottom unit.
4. Place upper unit on top of stacking base so holes
underneath are aligned.
5. Assemble four 1/2 – 13 bolts and lockwashers
through holes in stacking base into threaded
holes in bottom of upper unit where legs or
casters would be installed if unit were to sit
directly on the floor.
6. The plug cord must be routed from the bottom
right rear corner of the upper unit through a
slotted hole in the stacking base. Assemble the
strain relief (provided) around the electric cord
and route it through the slotted hole in the
stacking base.
7. Place rear cover on back of stacking base so the
D-slot captures the groove of the strain relief.
Attach rear cover with six 8 – 18 self-tapping
screws.
