Corporation will not be responsible for any
machine not properly operated or maintained.
Part I – Installation
Before starting this procedure, ensure that the
shipping carton does not show any evidence of
damage due to dropping or mishandling. This
may indicate that the dispenser was damaged
during transit or delivery.
!! IMPORTANT !!
Should the outside of the shipping carton give
any indication of possible damage, state this on
the bill of lading prior to signing. Contact the
freight carrier and request an inspection of
damage. If this procedure is not adhered to, you
will forfeit your rights to file a damage claim
and be responsible for subsequent repair costs.
A) Uncrating the Dispenser
1) The outer shipping carton is secured to the
shipping pallet with strapping. When cutting this
strapping, do so with caution as it may spring out
quickly. After cutting the strapping, lift the
shipping carton straight up and off of the freezer.
2) Remove the protective foam boards and plastic
wrapping from the outside of the freezer.
3) Unwind the power supply cord and inspect for
any damage that may have occurred during
transportation. If the cord is damaged or cut in
any way, contact an Authorized Service Agent
before connecting to a power source.
B) Positioning the Machine
After removing the machine from the shipping
pallet, it is now ready to be located in its final
location. Prior to choosing a location keep in
mind that the dispenser should be accessible for
periodic maintenance and have adequate space
for necessary airflow. Please allow 6 inches of
clearance on both sides of the dispenser.
The dispenser must also be level to ensure proper
drainage from the mix tank. To level, place a
level on all corners and shim as needed.
To seal the dispenser to the counter, proceed as
follows:
Determine the exact location you would like to
install the dispenser. Clean the counter top
thoroughly of any dust, dirt or oil.
Apply a thin bead (1/4”) of General Electric
RTV-102 (or equivalent) silicone sealant to the
lower mounting rim of the dispenser. (Refer to
Figure 1)

C) Electrical Requirements
!!! WARNING !!!
This machine must be properly grounded.
Failure to provide adequate grounding can
result in severe electrical shock and / or fatal
bodily injury.
This machine is provided with a power cord
connected to the unit. You should have already
inspected the cord for any damages that may have
occurred during shipping. If there is no damage to
the cord, you may plug it into the electrical
receptacle.
For this dispenser, you will need to provide a
dedicated electrical circuit with a rating of
115vac / 60hz / 1phase – 15amperes. This
receptacle should be no farther than 6 feet from
the dispenser and at no times should an extension
cord be used. This electrical circuit must comply
with your local and / or state regulations.
Part II – Explanation of the Controls
A) Front Touch Pad / CPU Unit
The model KW-77 machine is equipped with a
central CPU unit. This unit contains the front
touch pad, which monitors and controls the
functions of the machine. The front touch pad is
also the switching mechanism which operates the
following:
*Refrigeration of the product
*Activates the pump for dispensing
*Set the mix tank storage temperature
*Set the portion size or continuous dispense
mode
*Calibrate the temperature sensing probe
*Displays mix tank temperature
Also contained in the CPU unit is a delay timer
for the compressor. This delay will not allow the
compressor to immediately start, but delay the
start for three minutes. This delay will allow the
internal refrigerant pressures to equalize, which
will minimize high starting loads on the
compressor.

B) Mix Injection Pump
Your Coldelite whipped topping dispenser is
equipped with a mix injection pump. This mix
injection pump injects air into the liquid mix
prior to dispensing. This pump has two internal
gears that are driven by a pump drive shaft. This
drive shaft couples with the pump motor through
a pulley and a belt.
The mix injection pump runs whenever the pump
drive motor is turning. To regulate the amount of
mix being dispensed, pivot the pump suction tube
either to the right (less mix/more air) or to the left
(more mix/ less air). (Refer to figure 3)
Figure 3
The air intake is through the front two holes of
the pump cover. Since the two air inlet holes are
fixed, the air intake is constant. To adjust your
overrun (yield) you must regulate the amount of
mix being pumped. The mix pump suction tube
will change the orifice size on the tube to allow
either more or less mix to be pumped.
You will also have to adjust your pump suction
tube orifice setting depending on your product
viscosity and texture desired.
The “Normal” operating position for the suction
tube on this dispenser is either one position to the
left, center, or one position to the right of center.
C)Texturizer and Dispensing Head
The texturizer and dispensing head are also
important parts used to dispense whipped product
from this machine.
The texturizer is used to whip the product that is
pressurized by the mix injection pump. The
texturizer consists of a stainless steel rod
enclosed inside a clear plastic tube. The
texturizer and tube are connected to the pump
cover on one end and the dispensing head on the
other end. The pressurized liquid is pumped
through the channeled texturizer, which whips
the product. The whipped product is then
transferred to the dispensing head and dispensed.
The dispensing head is made of high impact
thermo-plastic. This dispensing head is secured
to the machine by two pins attached to the
refrigerated front extension. To remove the
dispensing head, simply rotate the head counter
clockwise ½ a turn while pulling straight out.
Attached to the head is a pattern nozzle and
splashguard. These parts are secured to the
dispensing head with rubber orings.
