13. DAILY MAINTENANCE

(see picture 12 and 13)
The water level must be checked daily and adjusted
when needed. The machine will not operate properly if
the water level is wrong. It will wash less efficiently and
the risk of blocking the flush pipes will increase.
Check that no foam develops in the machine. This can
happen if you wash many wheels from cars that have
just been cleaned in automatic car washers. Likewise
foam can develop if you add detergents other than the
recommended (see chapter 4) to the water. Foam will
cause malfunction. The machine will wash less efficiently
and the risk of blocking the flush pipes will increase.
If shot medium is spilled on the floor it is absolute vital
to sweep the floor regularly to avoid risk of slippery
floor (see picture 11).

14. SERVICE

• Before removing the MotorCompartmentCover (see
picture 3), make sure to disconnect the power supply
and the airline supplying compressed air (see picture
4) to the machine.
• The MotorCompartmentCover (see picture 3) may
only be removed by authorized personnel due
to exposure of moving parts and easy access to
electrical parts.

15. IMMERSION HEATER

(See picture 20)
• The immersion heater default setting is scheduled
so that the water temperature is at operation
temperature between 07:00 and 16:00, Monday to
Friday (see chapter 11.5.3).
• The factory setting of the water temperature is 45ºC.
This value may NOT be increased since the water will
be too hot and lead to risk of burning injuries.
• PLEASE NOTE: Always turn off the main switch
before emptying out the water in the machine!
The heater will automatically be turned on again after
starting a wash cycle.

GP 24

16. CLEANRINSE

The GP-24 is equipped with an extra cleaning feature,
rinsing the wheels with clean tap water after finished
wash cycle and before blowing starts.
If the CleanRinse is being used in the machine, the water
change intervals may be increased to approximately
400 washes.
CleanRinse can be turned off, see chapter 11.4.
17. WATER CLEANING AND WATER
HANDLING (OPTIONAL)
The dirt on the wheels that are washed in a Hedson
wheel washer is the dirt from our roads and cars. This
dirt might also contain heavy metal residuals, especially
copper from the brakes, zinc and nickel. The permitted
limit values differ locally. Please contact your local water
authority about the handling of the waste water.
The waste water from this machine should be let out
through an oil separator. If required, the machine can
be equipped with an environmentally friendly water
cleaning and filtering system.
Hedson Technologies AB has developed an easy and
effective waste water cleaning method. The method
consists of a coagulation powder (art.no. R12076) that
is added into the machine while stirring the water. The
coagulation powder binds the heavy metal particles
through flocculation and these bigger particles can be
filtered away (art.no. R12038 hose filter and
art.no. R12037 basket filter). The purified water fulfils all
limit values and authority requirements.
When using equipment that handles warm water, there
is a risk of harmful bacterium emerging (water- and/or
airborne diffusion), especially if the water has been left
non-operative in the machine for a while. We therefore
recommend the following procedures:
• By adding a bactericide to the water in the washing
compartment (art.no. 230521, 2 litre per 300 litre
water)
• To empty out the water of the machine when not
using it.
PLEASE NOTE: BIO-291 or any other detergent must
not be used in the machine when using the Hedson
water cleaning method!
Contact your local sales rep. for information.
