A GENERAL

The periods and the procedures for maintenan-

ce  and  cleaning  are  given  as  guides  and  are

not to be construed as absolute or invariable.

Cleaning, especially, will vary depending upon

local water and ambient conditions and the ice

volume produced; and, each icemaker must be

maintened  individually,  in  accordance  with  its

particular location requirements.

B ICEMAKER

The followingmaintenance should be scheduled

at least two times per year on these icemakers.

1 Check and clean the water line strainer.

2 Remove  the  cover  from  the  float  reservoir  -

care to do not damage the two water sensors

- and depress the float to make sure that a

full stream of water enters into the reservoir.

If  not  gently  remove  the  float  valve  from  its

reservoir bracket than clean the hole of the

nozzle.

3 Check that the icemaker is levelled in side to

side and in front to rear directions.

4 Check that the water level in the water reser-

voir  is  below  the  overflow  but  high  enough

that it does not run out of the spout opening.

5 Clean the water system, water reservoir and

the interior of freezing cylinder using a solu-

tion of cleaner.

Refer  to  procedure  C  cleaning  instructions

and  after  cleaning  will  indicate  frequency

and procedure to be followed in local areas.

6 If required, polish the two sensor rods secu-

red to the float reservoir cover, heavy scale

sediment on them can be removed with the

help of a bit of cleaner.

7 With the ice machine and fan motor OFF on

air  cooled  models,  clean  condenser  using

vacuum cleaner, whisk broom or non metallic

brush taking care to do not damage the con-

denser/ambient temperature sensor.

8 Check for water leaks and tighten drain line

connections.Pourwater down bin drain line to

be sure that drain line is open and clear.

9 Check  the  ice  level  control  sensor  to  test

shut-off.  Close  the  bottom  of  the  ice  chute

and wait till it is completely full of ice so to cut

off the light beam for at least 6 seconds.

This should cause the immediate blinking of

the Bin Full YELLOW LED located in the front

of P.C. Board and, 6 seconds later, the total

stopping  of  the  ice  maker  with  the  simulta-

neous light up of the same LED (steady).

Within few seconds from the removal of the

ice between the sensor lights the ice maker

resume its operation.

10Check  for  refrigerant  leaks  and  for  proper

frost line, which should frost as far as approx.

20 cm (8") from the compressor.

11When  doubtful  about  refrigerant  charge,

install  refrigerant  gauges  on  corresponding

service  valvesandcheckforcorrect  refrige-

rantpressures.

12Check  that  fan  blades  move  freely  and  are

not touching any surfaces.

NOTE. 

Cleaning  requirements  vary  accor-

ding to the local water conditions and indivi-

dual user operation.

NOTE: 

The ice level control uses devices

that sense light, therefore they must be kept

clean enough so they can “see”.

clean soft cloth.
