Unit Operation And Components; Electronic Temperature Control - Ojeda CTRH Series Installation And Operation Manual

- Do not block the lower ventilation grille with the packages about to be loaded.
- Do not over hang the shelf.
- Do not press the product against the rear wall
- Never exceed the shelf weight limits.
The unit is provided with an electronic temperature control that controls the operation of the unit
based on the temperature of the air entering the evaporator at the front of the unit.
In order to achieve the desired product temperature, the electronic control is factory adjusted to turn
off the refrigeration system at 28ºF and start it at 39ºF.
When you plug the unit in, the control display will illuminate. However, there is a start-up delay of 2
minutes before the compressor(s) are energized. This delay avoids the possibility that during a pow-
er failure the compressors are forced to restart before the refrigerant pressures are equalized.
The control has been factory-adjusted with a defrosting cycle scheduled to last 6 minutes every hour
to ensure that the evaporator performs without any ice build-up.
None of the factory-programmed electronic control parameters can be modified unless an access
code is entered (only your distributor's technical personnel have that code).
