BACKFILLING

1 In situations where the chiller is situated physically lower than the application being cooled,
fluid will apply pressure to the water circuit of the product.
2 The weakest seal is normally the tank lid, and this is typically where fluid will escape the unit.
3 Ideally, the product will be located higher or level with the product waterline. If this is not
possible, a non-return solenoid valve kit can be installed as an optional standard assembly.
4 Please raise any questions with the sales team on sales@app-therm.com.

VOLTAGE SELECTION

Different chillers will have different requirement for electrical supply. The specification and

requirement can be found on the back plate of the chiller. Please ensure that the voltage
supply and number of phases are correct on the site and your power supply can handle the
stated current draw.

FILLING PROCEDURES

a) Check all application valves are open, including solenoid valves and variable position valves.
i) The product will require an open water circuit to pump into.
ii) Any obstructions can increase the time, or entirely prevent the bleeding of air from the
system.
b) Remove the cap from the tank lid on the top of the product.
i) Fill the tank to just underneath the bottom of the filling port.
c) Switch the unit on
i) Immediately after toggling this switch (assuming the power cord is connected and
switched on), the pump will start running.
ii) Keep the unit running until the water level in the tank drops and cuts out on the level
switch interlock.
iii) Turn the unit off at the main switch.
iv) Fill the tank again to lift the level switch.
v) Start the product
Caution: Do not run the pump dry. Do not deadhead the pump.
d) Repeat step c) until the chiller does not cut out on the level switch.
e) Now with the unit running:
i) Leave the cap off the tank for >30mins to allow air to escape, or very loosely screwed on
to prevent water splashing out of the tank if the unit has a 'flow through' design.
f) Check the application and tubing for signs of leaks whilst the chiller is running.
i) Replace the tank lid fully when satisfied the system is full and bled of air and no
abnormal sound can be heard from the pump
