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  fixture  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 fixture can now be lifted off the crate 

skid. 

lift only at base of stand!

exterior loading

These models have not been designed to support excessive 

external loading. 

do not use the lower surfaces, glass, 

or shelves as a stepping ladder. do not stand in lower 

cases to gain access to the upper portion of the case. 

do not stand on any opening in the side panels.

 Failure 

to observe these warnings could result damage to the case 

and serious personal injury.

leveling

iMPoRtant! it is imperative that cases be leveled from 

front to back and side to side. a level case is necessary 

to  insure  proper  operation,  water  drainage,  glass 

alignment,  and  operation  of  the  hinges  supporting 

the glass. leveling the case correctly will solve most 

hinge operation problems.

NOTE:   A. To avoid removing concrete flooring, begin lineup 

leveling from the highest point of the store floor.

 

B. When wedges are involved in a lineup, set them first.

All  cases  were  leveled  and  joined  prior  to  shipment  to 

insure the closest possible fit when cases are joined in the 

field. When joining, use a carpenters level and shim legs 

accordingly. 

case must be raised correctly, under legs 

where support is best, to prevent damage to case.

1.  Check level of floor where cases are to be set. 

Determine the highest point of the floor; cases will 

be set off this point.

.   Level and set the case. Case must be raised under 

legs where support is best to prevent damage to 

case. Internal bracing may be removed at this time.

It is the contractor's responsibility to install

case(s) according to local construction and

health codes.

Plumbing

Self contained cases

MZ3 self-contained cases do not require that a condensate 

drain  be  connected  because  all  of  the  condensate  is 

contained by the condensate pan. However it is required 

that the condensate pan be cleaned on a regular basis. 

Additionally, the condensing unit should be cleaned at the 

same  time  using  a  light,  non-abrasive  brush  to  remove 

accumulated dust. If a filter is installed, it should be cleaned 

at this time as well.

installing condensate drain (When applicable)

Poorly  or  improperly  installed  condensate  drains  can 

seriously interfere with the operation of this refrigerator, and 

result in costly maintenance and product losses. Please 

follow the recommendations listed below when installing 

condensate drains to insure a proper installation:

1 .  Never use pipe for condensate drains smaller 

than the nominal diameter of the pipe or P-TRAP 

supplied with the case.

 .  When connecting condensate drains, the P-TRAP 

must be used as par t of the condensate drain 

to prevent air leakage or insect entrance. Store 

plumbing system floor drains should be at least 14" 

off the center of the case to allow use of the P-TRAP 

pipe section. Never use two water seals in series in 

any one line . Double P-TRAPS in series will cause 

a lock and prevent draining.

3 .  Always provide as much down hill slope (“fall”) as 

possible; 1/8" per foot is the preferred minimum. 

PVC pipe, when used, must be supported to 

maintain the 1/8" pitch and to prevent warping.

4 .  Avoid long runs of condensate drains. Long runs 

make it impossible to provide the “fall” necessary for 

good drainage.

5 .  Provide a suitable air break between the flood rim of 

the floor drain and outlet of condensate drain. 1" is 

ideal.
