PRE-INSTALLATION PROCEDURES
Inspection for Shipping Damage
You are responsible for filing all freight claims with the delivering truck line. Inspect all
cartons and crates for damage upon arrival. If there is damage to shipping crates,
cartons, or if a shortage is found, note this on (all copies) of the Bill of Lading prior to
signing.
If damage is discovered when the case is uncrated, immediately call the delivering truck
line. Follow-up the call with a written report indicating concealed damage to your
shipment. Ask for an immediate inspection of your concealed damaged item. Crating
material must be retained and shown to the inspector from the truck line.
INSTALLATION INSTRUCTIONS
Locating the Display Case NOTE: This case is designed for indoor use only.
The case should be located where it is not subjected to the direct rays of the sun,
heating ducts, grills, radiators, or ceiling fans, nor should it be located near open doors
or main door entrances. Avoid locations where there is excessive air movement or air
disturbances. Avoid high humidity locations, such as near other cases with water
misting or fogging devices.
The condenser air inlet is located on the front left of the case. The condenser air outlet
is located on the right front of the case. Do not block these vents. Do not place the case
in a location where the air inlet is near a source of heat.
Grill Removal
WARNING: Electrical shock hazard. Do not operate unit with panels removed.
Both front and rear base grills must be removed for merchandiser installation.
Front Base Grill Removal
On all cases manufactured before 02/01/2018, there is (1) front base grill. It is secured
at the top with (2) fast lead captive screws. There are tabs on the bottom of the grill that
insert into slots on the base. To remove the front grill, start by removing the (2) fast lead
captive screws. Next, pivot the top of the grill away from the case while lifting it to free
grill taps from the slots in the base.
Refrigerated Self-Serve Merchandiser (High Profile) Page 5
On all cases manufactured after 02/01/2018, there are (2) front base grills. They are
held by a pocket at the top and fasteners at the bottom. The left front grill is held at the
bottom by (1) thumbscrew, allowing easy removal for access to the control, the power
switch, and the condenser air filter. The right front grill is held by (2) Philips head
screws. To remove a front grill, start by removing the hardware at the bottom. Next,
lower the grill while rotating the bottom away from the case to free grill from the top
pocket. NOTE: The left grill must be removed prior to the right grill.
Rear Base Grill Removal
The rear base grill is secured with (5) self-threading screws.
Both base grills must be replaced after merchandiser installation. All base grills must be
in place for proper operation of the merchandiser.
Removing Case from Shipping Skid
CAUTION: If a Johnson bar or pry bar is used to move the case, make certain that
the case is lifted under the welded steel frame, and not by the end panels of the case.
Damage to the ends will result from lifting under the end panels.
Move the case as near as possible to the final location before removing it from the
shipping skid. Remove the front and rear base grills as outlined above in Grill Removal.
Remove the (three or four sets of bolts, nuts, and washers depending on case size) that
secure the case to the shipping skid. The hardware used to mount the case to the
shipping skid can be discarded at this point.
Removing Packaging Material
Remove the bubble wrap and packing material for all shelves, etc. If it is necessary to
remove tape residue from various materials, use cleaning compounds recommended in
the CLEANING INSTRUCTIONS chapter, (Pg. 21).
Leveling the Case
The case must be level for proper drainage of defrost water to the condensate
evaporator or condensate pump.
Check the level of the case along the front rail and along the top of the display pan.
Where applicable, adjust the (4) levelling feet on the base to level the case. If levelling is
required and the case is not equipped with levelling feet, shim under the case frame as
needed to level the case. It is recommended that the leveled case be sealed to the
floor with an NSF Listed Sealant.
Condensate pump
Check that the condensate drain line has not been dislodged during shipment, and that
the drain trap terminates properly into the water reservoir of the pump.
Refrigerated Self-Serve Merchandiser (High Profile) Page 6
Attached to the pump discharge port is a 25’ length of 3/8” ID braided vinyl hose. Verify
that the condensate hose has not become disconnected during shipment. The vinyl
hose exits the rear base grill and is routed up the rear of the case. It is clamped to the
rear of the case in multiple locations. The vinyl condensate hose must be installed by
qualified personnel only. The hose needs to be routed properly with no kinks in the hose
at time of installation, and vertical lift cannot exceed 20’. NOTE: On cases equipped
with casters, it is necessary to allow adequate slack in the hose so the case can be
rolled away from the wall. This is accomplished by creating a loop behind the case
using 6’ of hose.
Cleaning for Initial Setup
For initial setup, clean the case as outlined in the “Weekly Cleaning” section (Pg. 23) of
the “CLEANING INSTRUCTIONS” chapter of this manual.
Lights
Standard LED Top Light
The case comes with one standard led top light internally wired to the power
source. The light switch is in the top light housing under the top canopy.
Standard LED Shelf Lights
The case comes with standard LED shelf lights. Be certain that the shelf light cords are
completely inserted into the sockets in the end of the light. Improper or incomplete shelf
light cord and socket connection may cause arcing, causing damage to the plugs and
sockets.
The power supply used on this case allows removal of one or more shelf lights without
affecting the remaining lights. However, turn the light switch to the “off” position before
connecting or disconnecting any light cords.

ELECTRICAL CONNECTION AND GROUNDING
INSTRUCTIONS
Electrical Supply Wiring
DANGER: Improper or faulty hookup of electrical components in the
display case can result in severe injury or death.
THIS CASE MUST BE GROUNDED
Standard Power Cord
All standard RSSM3078 Units have an 8’ long power cord and plug, per the electrical
specifications of the case. Before plugging the case in, use the information found on the
case’s electrical rating plate to verify that the circuit to be used will meet the case’s
electrical requirements.
Optional Permanent Connection
• Only a licensed electrician must perform all case electrical connections.
• All electrical wiring hookups must be done in accordance with all applicable local,
regional, or national electrical standards.
• A separate circuit for each display case is required to prevent other appliances on
the same circuit from overloading the circuit and causing malfunction.
• The electrical service must be grounded upon installation.
• See the electrical data plate located at the rear of the case for circuit load and wire
current capacity.
• The electrical connection box is accessible from the rear of the case. Power Supply
wiring can be routed through the floor of the base frame or through the access hole
in the rear of the unit. Remove the electrical box cover to access the electrical
connections.
