VENTILATION
If the unit is enclosed, be sure that there is adequate air available for cooling. For the most effective
operation, do not allow ambient temperatures around the unit to rise above 75 F / 24 C. Warm
temperatures may reduce the ability of the unit to provide lower humidity’s.
Should the unit be mounted in an enclosure (e.g. beneath the showcase),
provide at least TWO ventilation holes. A flexible exhaust hose must be attached to the
four inch / ten centimetre mounting on the front of the unit, and directed out of the
enclosure through one of the ventilation holes.
Adequate fresh air for cooling must be provided, through a hole(s)
totalling at least 16 square inches / 100 sq. cm. All ventilation holes’ must
be unimpeded (do not cover with any cloth, mesh, or perforated metal).
Avoid re-circulating exhaust air by separating the holes as far from each other as
possible. For example, provide an upper hole for connection to the exhaust hose and a
lower hole for fresh air intake. Be aware of walls or obstructions which might trap and
re-circulate exhaust air into the fresh air intake.
NOTE: Although all Mini One XL machines are ready to connect a 4" (100 mm) exhaust hose and hose
termination, they are not included in the standard shipment and must be ordered separately.
WiFi ANTENNA
WiFi Antenna needs to be installed only if
monitoring service is in use. If the machine is
located inside a metal enclosure (eg. Under a
case made of steel) it is highly possible that the
WiFi connection will be poor or non-existent. In this situation, the antenna
needs to be installed outside of the metal enclosure. Wifi antenna extension
cord can be supplied by Preservatech. (Antenna is included in a standard order;
extension cord is an additional option)
EXTERNAL CONNECTION
The Mini One XL is equipped with external connectors:
RH - The "OUT OF RANGE" alarm is a 12 VDC connector to power up an LED or other 12VDC device.
This alarm is activated when the RH at the sensor is lower or higher then SET VALUE ± “Rh error
offset” parameter (see Programming)
LW - The “LOW WATER" alarm is a 12 VDC connector to power up an LED or
other 12VDC device. This alarm is activated when the water level inside machine
falls below the lowest acceptable level. Water must be added to the machine
when this alarm is activated.
ER - The "EXTERNAL RESERVOIR" jack is used for connecting a automatic filling system or with water
reservoir.
NOTE: Although all Mini One XL machines are equipped with external
connectors, cables and LED's are not included in the standard shipment. They
must be ordered separately.
