RECEIVING 

 

A. LRP ships by carriers that we have used for many years and have selected for their good service, 

but accidents in shipping occur regardless of how much care is taken.  Therefore the following is 
very important: 

 

B.  Inspect unit at once for any shipping damage, including concealed damage. 

 

C.  You should check for any shipping damage 

immediately

, preferably before the carrier leaves 

your receiving dock, as nearly all shipments are FOB ship point. 

 

D.  If there is any damage, note it on the carrier's receiving documents and notify the office of the 

carrier immediately. 

 

E.  The responsibility of the shipper and the delivering carrier ends five days after goods are received.  

It becomes the responsibility of YOU, the customer, to unpack the unit and check for concealed 
damage caused during shipping.  Immediate attention should be given to this. 

 

F.  Retain all packing materials if damage is found. 

 

INSTALLATION AND STARTING INSTRUCTIONS 

 

LOCATION – This unit requires a minimum of 4 inches of air flow in back and 1 to 2 inches on the sides 

and top.  Leveling legs are required in front only.  Unit may have a slight tilt from front to back after 
legs are installed.  This is acceptable and is recommended on this unit. 
 

POWER SOURCE – The supply circuit to this cabinet must conform to all National and Local Electrical 

Codes.  Consult the cabinet Serial-Data plate for voltage, cycle, phase, and ampere requirements 
before making connection.   VOLTAGE SHOULD NOT VARY MORE THAN 5% FROM SERIAL 
PLATE RATINGS.  A separate circuit is recommended to prevent possible loss of product due to 
over-loading or failure of other equipment on the same circuit.  PROTECT THE CIRCUIT WITH A 20 
AMP DELAY-TYPE FUSE.   
 

STARTING – There are no compressor shipping bolts to loosen or valves to open.  All that is necessary 

after the freezer has been properly leveled is to plug the service cord into an electrical outlet.  Do not 
use an extension cord.  Be sure your freezer is properly grounded.  Use the 3-prong plug provided 
into a 3-prong grounded outlet.   (Only this method complies with national electrical codes, local 
codes and ordinances.)  Unless the above grounding method is followed, you are not protected 
against severe or lethal shock in the event of a short circuit of an electrical component or wiring of the 
freezer.  When starting this new appliance, allow the cabinet to operate a minimum of three hours or 
until it has started cycling normally before placing product in the cabinet.  The motor compressor may 
start and stop several times when the unit is first started or after defrosting, especially if the weather 
is very hot.  This is only normal functioning of the motor overload protector.  The motor compressor 
will cycle normally as soon as the excess heat has been removed.
