ARCTIC COMPACT & DELUXE
bracket, fan blade not rotating free from obstacles or some lose
component vibrating during machine working.
On Arctic Compact with multiple bowls it is necessary also to
remove the transmission belt from the pulleys and power on the
unit. If the noise is still present the cause can be the electric
motor once again. Otherwise, if the noise is not present
anymore, it is necessary to remove the magnetic pulleys
assemblies and check for the integrity of their ball bearings. If
necessary replace the entire magnetic pulley assembly.
If, removing the impellers, the noise is not present anymore it
means that the cause of can be in the impellers or in the
magnetic coupling. Check for worn impellers and if necessary
replace them. Clean the impellers and the pivots and if
necessary lubricate them with food grade lubricant. Install the
impellers and put some water into the bowls. If the noise do not
disappear it is necessary to check once again the pump motor
bracket planarity.
IMPORTANT
The impellers are designed to spin always submerged
and wet. It is very important to avoid to have them
spinning dry to prevent worn out. For this reason on
Arctic Deluxe always switch off pump of empty bowls
and on Arctic Compact remove the impeller of empty
bowls or fill them with water.

4 FAUCETS

Two different faucets are available both for Arctic Deluxe and
Arctic Compact series: pinch tube faucet and stainless steel
gravity faucet.

4. 1 PINCH TUBE FAUCET

This faucet is suitable for all kind of products, liquid or thick, with
or without pulp or other solid particles. In case of dripping, it is
necessary to drain the product out of the bowl, remove the pinch
tube, clean it with fresh water and check for wear on it. If
necessary, replace it with a new one.
4. 2 STAINLESS STEEL GRAVITY FAUCET
This faucet is suitable for liquid product without pulps or other
solid particles. In case of dripping, it is necessary to drain the
product out of the bowl, remove the stainless steel piston, clean
it with fresh water and check for wear of the rubber gasket. If
necessary, replace it with a new one. It is also necessary to
clean the piston housing in the bottom of the bowl and check for
the integrity of the rim around the piston hole (see figure 5).
5 SLOW MIXING SYSTEM
The dispensers of Arctic Deluxe series are available also with
slow mixers. Two kind of slow mixers are available: one with
magnetic driving (A) and the other with mechanic driving (B).
The first one is suitable for delicate drinks like tea or coffee while
the other one is suitable also for thick drinks (see figure 6).
In case of magnetic slow mixer improper rotation, the cause can
be a faulty drive motor, a magnetic mixer that can't freely rotate
on its pivot or ice on the evaporator caused by very low level of
product into the bowl.
In case of direct slow mixer improper rotation the cause can be
a foulty motor or an excessive thickness of the drink.

6 REFRIGERANT CIRCUIT SERVICE

6. 1 CHECKING FOR REFRIGERANT LEAKS
