7.14.3 AIR PURGE operation

MENU > FOR SERVICEMAN > TEST RUN > AIR PURGE

Once installation is complete it is important to run the air purge function to remove any air which may be present in the water

piping and which could cause malfunctions during operation.

The AIR PURGE operation is used to remove air from the water piping. Before

running AIR PURGE mode, make sure

that the air purge valve is open. When the air

purge operation starts, SV1 valve opens and SV2 valve closes. 60 secs later the

pump in the unit (PUMPI) operates for 10min during which the flow switch does

not work. After the pump stops, SV1 valve closes and SV2 valve opens. 60 secs later

both PUMPI and PUMPO operate until the next command is received. If any error

code is displayed during the air purge operation, the cause should be investigated.

Refer to Part 3, 10 “Error Code table”.

7.14.4 CIRCULATION PUMP RUNNING operation

MENU > FOR SERVICEMAN > TEST RUN > CIRCULATION PUMP RUNNING

The CIRCULATION PUMP RUNNING operation is used to check the

operation of the circulation pump. When the circulation pump running

operation starts, all running components stop. 60 secs later, the 3-way

valve opens and the 3-way valve closes. After a further 60 secs PUMPI

starts. 30 seconds later, if the flow switch detects that the water flow is

normal, PUMPI operates for 3 mins. After the pump stops 60s, the 3-way

valve closes and the 3-way valve opens. 60s later both PUMI and PUMPO will operate. After a further 2 mins the flow

switch start to check the water flow. If the water flow rate is sufficient, both PUMPI and PUMPO operate until the next

command is received. If the water flow rate is insufficient over any 15-second period, PUMPI and PUMPO stop and error

code E8 is displayed. Refer to Part 3, 10 “Error Code table”.

7.14.5 COOL MODE RUNNING operation

MENU > FOR SERVICEMAN > TEST RUN > COOL MODE RUNNING

The COOL MODE RUNNING operation is used to check the operation of the

system in space cooling mode.

During the COOL MODE RUNNING operation, the M thermal Mono unit leaving

water set temperature is 7°C. The current actual leaving water temperature is

displayed on the user interface. The unit operates until the leaving water

temperature drops to the set temperature or the next command is received.

If any error code is displayed during the cool mode running operation, the cause should be investigated. Refer to Part 3, 10

“Error Code table”.
