Commissioning “To Be Performed In Heating Mode Only”
An as-built design will need to be provided to Chiltrix by email before
the commissioning call.
For Commissioning please arrange a commissioning call with Chiltrix
Support Dept. +1 757-410-8640 Ext. 112
PLEASE MAKE SURE TO CALL CHILTRIX BEFORE COMMISSIONING
Preparation
After finishing the installation tasks, please check the items below:
1. Check the Wired Controller P Parameters for the most updated settings.
2. Check that the power cable is securely connected and the screws are tight.
3. Is the display lit on the wired controller after the power is applied?
4. Verify that all the shut off valves and manual valves are open. Insulate all water supply and return
pipes.
5. Test only in heating mode to verify proper water flow.
Water or Glycol Filling (See page 28) A 10% minimum glycol mixture is suggested to protect the unit from
freezing and provide corrosion inhibition. Refer to the chart on page 10.
1. With a hose and filling pump connected to the cx50 water system, and all air exhaust valves open in
the water system, fill the water loop with water and glycol mixture. Keep the air exhaust valves open
until there is a continuous flow of water and glycol mixture coming out of the air exhaust valve. Then
close the air exhaust valves. See page 30 and 31 for more details.
2. Discharge the air from both domestic hot water system and air conditioning water system. CXI fan
coils have a bleeder valve located near the inlet and outlet ports. The cx50 has a bleeder tube
attached to the Brazed plate heat exchanger.
To avoid freezing the heat pump when the air temperature drops below 32F in winter, you must use an
appropriate glycol and water mixture just in case the electricity is cut off. We recommend biodegradable
non-toxic HSE Corn Glycol, any Propylene Glycol (PG) can be used.
Running a Test- Call tech support if this is your first time commissioning a cx50.
Apply power to the cx50 and select heating mode using the wired controller. If there is not enough flow in
the system or air in the lines and you will get P5 and possibly P1 errors. Call tech support if any error codes
are displayed on the wired controller.

MOST IMPORTANT!
1. Always maintain an electrical connection with heat pump to enable the antifreeze function.2. Initial test
should be done in heating mode. Make sure it is not in cooling mode during first operation or running a
test, until you make sure the circulation pump is working properly and water is flowing properly. Failure to
do so will likely damage the heat exchanger and not be covered under warranty.
