measured by a probe inserted in sensor bottle inside the cabinet. The sensor
probe must be inserted in the glycerin bottle prior to operation.
The sensor bottle is positioned on the left wall towards the top of the unit.
To install the sensor(s) into the bottles, complete the following steps:
1. Remove the bottle from the bracket and verify that each bottle is full of
liquid.
2. Remove the solid cap from the bottle and save for the next time the unit
needs to be moved.
3. Remove the taped lid and temperature sensor(s) from the wall.
4. Insert the temperature probe(s) into the bottle.
5. Secure the lid to the bottle and return the bottle to the bracket.
Note : Temperature Sensor Accuracy:
Upper Bottle (RTD) = ± 1.0°C
The doors on all units are designed to stay open if opened 90 degrees or more.
The door spring tension cannot be adjusted.
If the self-closing door does not work properly, make sure the unit is level.
Door seal integrity is critical for unit's performance. Never route anything
through the door seal. A loose fitting gasket allows moist air to be drawn
into the cabinet, resulting in quicker frost buildup on the evaporator coil,
longer running time, poor temperature maintenance, and increased
operation cost.
CAUTION: Keep hands and body parts clear of closing doors. The moving
parts create a potential pinch point.
WARNING: Risk of Fire. There are port holes in the walls of the cabinet
to help facilitate routing of tubing, independent temperature sensors, and
other non-electrical items. The ports are not intended to supply power to
devices inside the device. Be sure to seal the holes after routing items to
prevent undesired air exchange.
