INTRODUCTION
Thank you for purchasing Master-Bilt Ice Merchandiser. This manual contains important instructions for installing,
using, cleaning, and servicing Master-Bilt Indoor Ice Merchandiser. A parts list is included with this manual. Read all
documents carefully before installing or servicing your equipment.
STORE CONDITIONS
The Master-Bilt Ice Merchandisers are designed to operate in a controlled environment. The temperature should be at
75°F or below for an indoor ice merchandiser, with relative humidity of 55% or less. At higher temperature or humidity
conditions, the performance of these merchandisers may be affected and the capacity diminished.
The Master-Bilt Ice Merchandiser should not be positioned where it is directly exposed to rays of the sun or near a
direct source of radiant heat or airflow. This will adversely affect the ice merchandiser and will result in poor
performance.
If this ice merchandiser is to be located against a wall, there should be at least 6” space between the wall and the back
of the unit. This space will allow for the circulation of air behind the ice merchandiser, which will prevent condensation
on the exterior surfaces.
WARNING LABELS AND SAFETY INSTRUCTIONS
This symbol is the safety-alert symbol. When you see this symbol on your ice merchandiser or in
this manual, be alert to the potential for personal injury or damage to your equipment. Be sure you
understand all safety messages and always follow recommended precautions and safe operating
practices.
