Description

The Hoshizaki 4A1482-01 Thermostatic Expansion Valve is an essential part of the refrigerant flow regulation system of ice making equipment, which is used with R-404A. Made of heavy duty copper, this valve is 1/4" ODF inlet and 3/8" ODF outlet for use with many ice machine models. The refrigeration system consists of a pressure release system that responds to temperature and pressure changes, to keep the system within an optimal working range in order to optimize the production of ice. This valve also increases energy efficiency in the ice machine provides better refrigerant control.

Step1: Disconnect electrical power and recover refrigerant using approved refrigeration service equipment before servicing.

Step2: Remove the access panel and locate the existing thermostatic expansion valve near the evaporator assembly.

Step3: Disconnect the sensing bulb, refrigerant lines, and mounting hardware from the old valve carefully.

Step4: Braze or connect the new expansion valve in the correct flow direction using proper refrigeration practices.

Step5: Secure the sensing bulb tightly to the suction line and insulate it properly.

Step6: Evacuate, recharge the system, and test for leaks, correct superheat, and proper ice production.
