<3> Installation
It is very simple to install this industrial cooling machine. The installation for the
first time of the new machine can be carried out by following steps:
1. Open the package to check if the machine is intact and all the necessary
accessories are completed.
2. Open the water supply lid to feed cooling water.
Observing the water level gauge to feed water slowly, be careful not to have the
water overflowed!
3. According to system conditions, please connect the water inlet and outlet pipe
properly.
4. Plug in power, turn on the power switch. (Do not start up without water in the
water tank!)
(1) Power switch turned on, the circulation pump of the chiller starts working. The
first time of operating may cause more bubbles in the pipe leading to a flow
alarming occasionally, but running for a few minutes later, it will go back to
normal.
(2) If the chiller starts for the first time, you must immediately check whether the
water pipe leaks.
(3) Power switched on, if the water temperature is under the set value, it is normal
that fans and other components of the machine do not work. The temperature
controller will automatically control the working conditions of the compressor,
magnetic valve, fans and other parts based on the set controlling parameters.
(4) As it takes a longer time to start over the compressor and other components,
according to different conditions, the time is range from seconds to minutes, so
do not turn on and off frequently.
5. Check the water level in the water tank.
The first starting up of a new chiller will empty the air in the water pipe, causing
a slight water level decline, but in order to keep the water level in the green area,
it is allowed to add adequate water again. Please observe and record the current
water level, and inspect it again after the chiller running for a period of time, if
the water level drops obviously, please re-inspect the water pipeline leakage.
6. Adjust parameters of temperature controller.
CWFL-4000 series use an new intelligent controller. It works in defaulted
constant temperature control mode for the low temperature end with water
temperature set at 25 ℃
temperature end works in intelligent control mode and it will self-adjust
controlling parameters according to the ambient temperature changes.
Normally users do not need to adjust the parameters. If it is necessary, please
refer to page 6 , "Unit introduction and parameters adjustment."
