<7> Simple troubleshooting

Failure

Failure Cause

Approach

Machine turned on but

unelectrified

Power cord is not plugged in place

Check and ensure the power interface

and the power plug is plugged in place

and in good contact.

Fuse burnt-out

Open the electric box cover, check the

protective tube, replace with spare one

if necessary and check whether the

power supply voltage is stable; Check

and ensure the power interface and the

power plug are in good contact.

Flow Alarm

(controller displays E6) use a

water pipe directly connect

to the water outlet and inlet

but still without water

flowing

Water level in the storage water tank is

too low

Check the water level gauge display,

add water until the level shown in the
green area; And check whether water

circulation pipe leaks.

Flow alarm occurs while

running with other

equipment

(controller displays E6), but

there is water flowing and no

alarm when use a water pipe

directly connected to the

chiller water outlet and inlet.

Water circulation pipes are blocked or

a pipe bending deformation.

Check water circulation pipe

Ultra-high temperature alarm

controller displays E2

Blocked dust gauze, bad thermolysis

Unpick and wash the dust gauze

regularly

Poor ventilation for air outlet and inlet

To ensure a smooth ventilation

for air outlet and inlet

Voltage is extremely low or astable

To improve the power supply circuit or

use a voltage regulator

Improper parameter settings on

thermostat

To reset controlling parameters or

restore factory settings

Switch the power frequently

To ensure there is sufficient time

for refrigeration

(more than 5 minuets)

Excessive heat load

Reduce the heat load or use other

model with larger cooling capacity

Alarm for ultra-high room

temperature

controller

displays E1

The working ambient

temperature is too high for the chiller

To improve the ventilation to guarantee

that the machine is running under 40

.

Serious problem of

condensate water

Water temperature is much lower than

ambient temperature, high humidity

Increase water temperature or

to preserve heat for pipeline

Water drains slowly from

outfall during water

Injection port is not open

Open the injection port
