PRE-INSTALLATION INSTRUCTIONS

INSPECTION FOR SHIPPING DAMAGE
You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons and crates for damage

as soon as they arrive. If damage is noted to shipping crates or cartons or if a shortage is found, note this on the bill of
lading (all copies) prior to signing.

If damage is discovered when the cabinet is uncrated, immediately call the delivering truck line and follow up the call
with a written report indicating concealed damage to your shipment. Ask for an immediate inspection of your concealed
damage item. Crating material must be retained to show the inspector from the truck line.

INSTALLATION INSTRUCTIONS

GENERAL INSTRUCTIONS

1. Be sure the equipment is properly installed by competent service people.

2. Keep the equipment clean and sanitary so it will meet your local sanitation codes. Clean the cabinet with a mild
detergent and water, then rinse.

3. Rotate your stock so that older stock does not accumulate. This is especially important for ice
cream. A "First-In, First-Out" rotation practice will keep the products in good salable condition.

4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the case for at
least 6 hours after it is started.

5. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of time.

6. When replacing light bars, be sure that the electrical power to the lighting circuit is turned off.

MECHANICAL

Remove front grille and check refrigeration lines to see that they are free (not touching each other or compressor).
Spin condenser fan blade to see that it is free.

LOCATION

Remove cabinet from crate base and slide into location. Cabinet must be level from side to side and front to back for
correct draining of coil pan and for self-closing doors to operate correctly.

To comply with Sanitation requirements the cabinet must be sealed to the floor with a N.S.F. listed silicone sealant,
mounted on casters, or with 6” minimum legs. 0” air space is required for the front and each side. The top and back of
the cabinet must be left open for compliance.

Remove shipping supports from bottom edge and top edge of doors.
