The RDI comes in various lengths and should be installed
in a proper and uniform manner. The following guidelines
will help ensure proper installation.
1. Case location should be near a fl oor sink or waste
outlet - with electrical and refrigeration access
usually under the case.
2. All plumbing should conform to local codes.
3. When the RDI is to be installed in an existing fi xture
or in a supplied fi xture, the RDI and the new or
existing fi xture should be leveled front to back and
side to side.
4. The electrical junction box is located under the RDI
which is where the electrical is terminated by the
manufacturer. The junction box is a standard 2x4
box with knock-outs and cover.
5. The refrigeration is also stubbed down under the
case for connection to liquid and suction lines from
the remote RDI case.
6. In cases where more than one RDI are installed, run
drains separately to the sink or drain outlet.
7. For RDI units installed in an existing table, the lip
on the unit should be sealed with a NSF approved
sealant and all Phillips screws slots should be
sealed with same.
8. The RDI should be dropped in the existing table
oriented with the discharge air blowing from the front
to the back of the fi xture, the front is identifi able by
the adjustable top air discharge control pins.
9. A thermostat and solenoid mounted in the suction
line is recommended for temperature control and
defrost.
10. Set defrost per case specs section of this book.
Location
The refrigerated merchandisers have been designed
for use only in air conditioned stores where temperature
and humidity are maintained at or below 75°F and 55%
relative humidity. DO NOT allow air conditioning, electric
fans, ovens, open doors or windows (etc.) to create air
currents around the merchandiser, as this will impair its
correct operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from the
time the product is received, through storage, preparation
and display, the temperature of the product must be
controlled to maximize life of the product.
Uncrating the Stand
Place the fi xture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the case
from the skid. The fi xture can now be lifted off the crate
skid.
Lift only at base of stand!
Exterior Loading
These models have not been structurally designed to
support excessive external loading. Do not walk on their
tops; This could cause serious personal in jury and damage
to the fi xture.
Leveling
IMPORTANT! IT IS IMPERATIVE THAT THE RDI AND
THE FIXTURE THAT THE RDI IS INSTALLED IN,
BE LEVELED FROM FRONT TO BACK AND SIDE
TO SIDE PRIOR TO JOINING. A LEVEL CASE IS
NECESSARY TO INSURE PROPER OPERATION,
WATER DRAINAGE.
NOTE: A. To avoid removing concrete fl ooring, begin lineup
leveling from the highest point of the store fl oor.
B. When wedges are involved in a lineup, set them fi rst.
