Cleaning Switch
Located on the bottom side of the control box, it is used to energize the water inlet and the hot gas valves to fill the sump of the machine with water when needed.
Green Master Switch Push Button
Located in the front of the machine it’s used to switch ON and OFF the unit by pushing its green push button. When ON, its green light is ON.
Red Alarm/Re-Set Push Button
Located in the front of the machine (just beside the Master Switch) it works in conjunction with the Cleaning Remind Board and it’s activated when:
1. ON steady with machine in OFF mode
Condensing temperature is higher then 70oC or 158oF. (air cooled version)
2.Blinking twice and repeat with machine in OFF mode
Condenser sensor out of order.
3.ON steady with machine in ON mode Condenser air filter needs to be cleaned.
4.Slow blinking with machine in ON mode. Water system needs to be cleaned.
In the first case the machine can be
In the second case, first replace the condenser sensor then, push and hold the Red
Cleaning Reminder PC Board
Located on the front left side of the machine, it works in conjunction with the condenser sensor and the Red Alarm
It consists of
Printed Circuit Board with a step down transformer (115V - 12V)
Relay
Dip Switch with two keys
Jumper for the set up of the Cut OFF/Alarm condensing temperature (70oC 158oF.- jumper OUT - for air cooled)
green four wire connector for power IN and
OUT
Red socket for the Water Level Sensor (future use)
Black socket for the Condenser Sensor and
White socket for the Red Alarm
The main function of this PC Board is to switch the machine OFF when the condensing temperature is too high or signal the need for cleaning the condenser air filter or the water system. The time between the signal for the cleaning of the water system can be modified according to the setting of the two Dip Switches as below:
Time | 1 | 2 |
1 Month | On | On |
3 Months | Off | On |
6 Months | On | Off |
1 Year | Off | Off |
Once the water system has been cleaned, push and hold the Red Alarm
Condenser Air Filter
It is located in front of the air cooled condenser. It can be removed by pulling it through the opening in the front panel for cleaning or replacing. A lower plastic guide, installed inside the unit, is used for the correct sliding and location of the air filter.
Condenser Sensor
The condenser temperature sensor probe, located within the condenser fins detects the condenser temperature variations and signals them by supplying current, at low voltage, to the P.C.
BOARD.
In case the condenser temperature rises and reaches 70oC (160oF) – the control system will cause an immediate and total stop of the machine’s operation.
