EFRIGERATION
A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjustments
are made. The refrigeration technician must use high and low side pressure readings, water and air temperatures,
plus general conditions of cleanliness to assess the refrigeration system status when making any adjustments.
All icemaker products are tested and adjusted at the factory prior to shipment where the ambient temperature
ranges from 65_ to 90_F, depending on the season of the year.
Whenever a new icemaker product is initially installed and started-up, it is imperative that the start-up operation
make the following checks and/or readjustments for local conditions.
