Jet Spray (Cold) Training Manual

3.8 Evaporators

There are two types of evaporators on the Jet Spray cold products, coil and dome. It is important on both to remember to keep product above the top of the coils to insure proper cooling of the product and correct operation of the cooling system.

Sometimes there is an ice build up around the evaporator. This is normal.

When operating a multiple bowl unit, it is necessary to have liquid above the level of the evaporators in each bowl, this balances the refrigeration unit. Never run with an empty bowl, fill with water if product is unavailable.

3.9 Air Flow

It is very important to make sure that there is adequate air circulation around the machine. There should be a minimum of three inches of space all around the unit. Refer to the installation and owners manuals for additional information.

3.10 Refrigeration Charging

Charging the capillary tube controlled system requires accurate charging equip- ment and technique. The amount of refrigerant in the system determines the oper- ating pressures and temperature of the evaporators. It is necessary to utilize a refrigerant scale or graduated charging cylinder when charging the system.

Load, ambient temperature, and operating conditions affect sealed system operat- ing pressures. If the unit appears under charged, check for a dirty condenser. If the unit is running constantly but not cooling, the problem may be a low charge. If a low charge is suspected, it is recommended that the system is evaluated and leak tested.

NOTE: Hooking up a high side hose to a system with a low charge causes a quarter or more of the charge to backup into the hose. This results in an incorrect reading. This is why operating pressures are not normally published.
