4. If the condenser is dirty, place a wet towel over the
front (outside) of the condenser.
5. Using compressed air or a CO2 tank, blow out the
dirt from the back (inside) of the condenser. Most of
the dirt will cling to the wet towel.
NOTE
This procedure will result in a very loud noise.
6. An alternative method of cleaning the condenser is
to use a condenser brush and vacuum.
NOTE
If the condenser is not kept clean, loss of
refrigeration efficiency will result; causing
extended run time or soft product consistency.
Water-cooled condensers need an unrestricted
supply of cold, clean water.

T.X.V.
A T.X.V. (Thermostatic Expansion Valve) (Figure 34)
is used to meter the refrigerant to the evaporator. The
self-regulating T.X.V. is preset at the factory.

T.X.V. ADJUSTMENT
T.X.V. adjustment is not recommended. Any attempt
to adjust the T.X.V. will cause the freezer to be totally
out of calibration.

T.X.V. REMOVAL
CAUTION
IF A T.X.V. REPLACEMENT IS NEEDED, A
HEATSINK (WET CLOTH) MUST BE USED TO
PREVENT DAMAGE TO THE VALVE.
WARNING
DISCONNECT FREEZER FROM ELECTRICAL
SUPPLY SOURCE BEFORE SERVICING.
1. Remove the two Phillips head screws from the bottom
of the front and side panels then slide the panels
down and out (Figure 35).
2. Remove the bulb from the suction line exiting from
the evaporator (Figure 35).
