8. MACHINES WITH AIR-COOLED CONDENSER
Figure 11
The freezer requires a minimum of 200 mm of clearance on both sides
and 500 mm in the rear of the unit. (Figure 11)
The clearance will allow sufficient amount of air flow across the condensers. Failure to
allow adequate clearance can reduce the refrigeration capacity of the freezers and cause
permanent damage to the compressors.
Position the machine for easy accessibility for cleaning, servicing and maintenance. A
clean environment is also essential for the proper performance of the freezer.
Attention: The freezer must not be exposed to direct sunlight. If it
stands in direct sunlight the performance will decrease. As the air
temperature increases the performance decreases. This is true for all
refrigeration equipment.
24
EFE 2500 AP/APS/ANP/APH
9. MACHINES WITH WATER-COOLED CONDENSER
Figure 12
Water-cooled machine must be connected to running water supply, or a
cooling tower. Water must have a pressure between 1-10 bar and a
delivery at least equal to the estimated hourly consumption.
Connect inlet pipe marked by plate “Water Inlet” to water supply installing a shut-off valve,
and outlet pipe marked by plate “Water Outlet” to a drain pipe, installing a shut-off valve.
If water valve is retarded, this operation will have to be carried out by skilled
personnel. Valve adjustment must be carried out in such a way that no
water flows when machine is off and lukewarm water flows when machine
is on.
Water consumption increases if temperature of entering water is above 20°C.
The filter should be cleaned every 3 months.
The use of potable water in the cooling system is recommended.
25
EFE 2500 AP/APS/ANP/APH
10. CONTROL DIAL
Figure 13
The CONTROL DIAL has the following selections:
STOP
In the STOP position No refrigeration occurs in hopper and barrel.
WASH
In the WASH position the Soft-serve in the barrel will be agitated, however no refrigeration
will occur.
STAND-BY
In the STAND BY position the barrel will retain frozen product in a semi-soft state for
prolonged periods of non-use. Both barrel and hopper will be chilled.
SOFT / HARD
Choose the SOFT / HARD selection depending on the type of Soft-Serve Product you
have chosen and the consistency you find more preferable.
26
EFE 2500 AP/APS/ANP/APH
11. OPERATING PROCEDURE
1. Always wash your hands with soap and potable water before assembling the machine.
(Preferably use new paper towels to dry your hands)
2. Only use the removable parts after they have been washed sanitized and air-dried.
3. Fit the beater assembly only when machine is off.
4. Follow all the instructions of this manual and the operating procedures of the store
owner, and at all times follow recognized in-store hygiene procedures, in particular those
in respect of dairy products.
5. Repairs must be done by the persons who are authorized by Smach®, if not, any
product failure warrantee will become invalid and void.
12. PREPARATION AND START UP PROCEDURE
12.1 PREPARATION
Make sure that all the removable parts have been washed with potable
water and sanitized, and then air dried before they are used.
Attention: NEVER ASSEMBLE OR DISASSEMBLE ANYTHING
UNLESS YOU HAVE:
1. Selected the STOP Mode.
2. Switched off the power at the wall and un-plugged the power cable.
27
EFE 2500 AP/APS/ANP/APH
You must use food grade lubricant to do the assembly described below.
Prepare the mixture as shown in product description.
12.2 STARTING THE MACHINE
Let the Barrel fill up with the MIX (The Barrel will be full when the air stops bubbling from
the Barrel)
Fill the hopper, up to the level of the suction tube handle (Figure 16). Do
NOT fill above the suction tube handle. It will leak into the drive
shaft and cause problems. Wait till all the air has bubbled out of the
barrel. The barrel will be full when the bubbling stops.
Figure 14 Figure 15
28
EFE 2500 AP/APS/ANP/APH
Figure 16
Carefully insert the Compression Feed Pipe into the Barrel Feeder Tube
hole on the floor of the hopper.
Now proceed to connect the Compression Feed Pipe assembly into position
by pressing the bottom end into the hole in the hopper floor. Initially keep it
at 90º to its final direction feed.
Then close the Hopper Cover and turn the control dial to the WASH mode to start the
aeration pump.
Figure 17
Wait 2 minutes and open the Hopper Cover. When you open the cover,
wash mode is automatically turned off and pump will stop in a few seconds.
If the mix is pumping out of the hole, as shown in the picture above, pump
is working properly. Wait the pump to stop (Figure 17) and then the
Aeration Pump Connecting Tube can be connected.
29
EFE 2500 AP/APS/ANP/APH
Figure 18
Now the pump has stopped pumping which indicates that the pump is off. Now connect the
aeration pump connecting tube.
Figure 19
Turn the aeration compression feed pipe towards the pump and connect.
Lock the plastic sliding fitting into position as shown on the picture.
Close the hopper cover and turn the freezer to WASH mode again and wait
2 minutes. Then discharge ice cream to take out pressure. Otherwise, the
barrel can freeze and it may damage the freezer. When you pull the
Dispensing Handle, if there is no pressure, you must check the pump
assembly.
30
EFE 2500 AP/APS/ANP/APH
After taking the pressure out, the freezer is ready to use. Place the Hopper
Cover, turn the control dial to SOFT or HARD mode and wait till the freezing
down has completed. The Freezer will stop and become quiet when the
Soft-serve is frozen down for the selected state of SOFT or HARD. (Once
the machine has reached the selected hardness the refrigeration
compressor will automatically stop for pre-set intervals).
12.3 DISPENSING ICE CREAM
After the Freezer has frozen down and stopped, pull the Dispensing Handle
and dispense about 300 grams of Soft-Serve into a washed and sanitized
beaker.
NOTICE: The temperature of the Soft-serve should be between: -6.5ºC
and -8.0ºC.
When a serve is dispensed the Freezer is automatically activated by the movement
detector switch when it senses the cone in hand being held below the dispense head
nozzle.
13. STEP-BY-STEP CLEANING - SANITIZING PROCEDURE
When properly used and cared for the machine will provide a consistent
quality Soft-Serve or Frozen Yoghurt. Like all equipment used to
manufacture food products it will require daily cleaning and regular
maintenance. A specified amount of care and attention is required
including but not limited to everything prescribed in this manual.
Attention: Because of bacteria population increases very fast, cleaning
and sanitizing is vital. Extra attention must be given for cleaning and
sanitizing properly.
31
EFE 2500 AP/APS/ANP/APH
13.1 CLEANING PROCEDURE
Follow these steps for cleaning: (All water used must be potable water)
1. Pull the handle to take ice cream for dispensing the pressure in the system.
2. Remove the compression feed pipe. Never remove the pipe without dispensing some
ice cream. Otherwise, the mix can squirt.
3. Remove the aeration pump.
4. Fit the Pump Cleaning Plug to the Pump Hole. (Figure 20)
Figure 20
5. Close the hopper cover and turn the machine to “WASH” mode and wait 3 minutes.
6. Place an empty container under the dispense head and drain the remaining Soft-
Serve and liquid into a clean, sanitized bucket. Immediately place a tight sealing lid
onto the bucket and store refrigerated (preferably below 5ºC)
7. Fill the hopper with cold water and allow the machine to run for 2-3 minutes before
draining the water into the bucket.
8. Refill the hopper with warm water and sanitizer as per the sanitizer manufacturer’s
instructions.
9. Fill the hopper with warm water. Allow the machine to run for approximately 5

13.3 SANITIZING PROCEDURE
After cleaning procedure, hopper, barrel and all the removable parts must
be sanitized. It is recommended to use approved “SMACH
®
Sanitizer”
during disinfection. (Please contact SMACH® to provide approved
“SMACH
®
Sanitizer”.)
The SMACH® sanitizer is based on alcohol and QAC.
It is suitable for metals against corrosion.
It provides a fast and effective disinfection.
It is a volatile material, so it leaves no residue on the applied surface.
- Keep out of reach of children.
- Rinse well after application.
- Avoid eye contact. In case of contact, wash with water immediately.
- Avoid skin contact.
- Do not use for face, body, hand and food cleaning.
- Keep in a cool place.
- Do not expose to direct sunlight.
Directions to Use
It is a ready to use solution. Apply through spraying and wiping. It is recommended to wait
at least 5 minutes after spraying.
The sanitizing solution mustn’t be mixed with water.

14. STEP-BY-STEP ASSEMBLY PROCEDURE
14.1 DISPENSING HEAD ASSEMBLY
14.1.1 Dispensing Head O-Ring Assembly: Again, place a small amount
of lubricant onto your index- and middle finger and hold the large
DISPENSING HEAD SEAL O-RING between the lubricated fingers and
your thumb. Gently pull the O-ring through your lubricated fingers until it is
entirely covered. The coating of lubricant should be thicker than on the
piston as it will prevent the O-ring from slipping during the latter stages of the assembly.
Place the O-ring gently into the designated groove of the Dispensing head and press firmly
into place.
Figure 26 Figure 27
14.1.2 Dispensing Head Piston – O-Ring Assembly: Assemble the
Dispensing Head piston using food grade lubricant. Slip the appropriate O-
rings onto the piston.
Place a small amount of lubricant onto your middle and index finger and
evenly coat the piston’s entire surface. The coating must be all-encompassing but must
not be too thick; a very thin layer will suffice
.

14.1.3 Dispensing Head Piston Assembly: Insert the lubricated piston
into the dispense head. This motion should be quite free and without too
much force. If the piston does not move freely, a little more Lubricant is
required.
In that case, remove the piston, add a little more lubricant as prescribed
above and re-insert.

14.3 INSERTING THE ASSEMBLED BEATER INTO THE BARREL
Figure 48 Figure 49
Make sure the barrel is free of any obstruction before you insert the beater.
The beater must slide in easily with a final firm push and some turning to
align the shaft with the gearbox socket.
When it is pushed in the silicon seal will push it out a few millimeters like a
spring. Do not be concerned about this, as you place the dispensing head
on, the dispense head will push it into position.

14.4.3 Speed Adjustment:
The speed (mass flow rate) of discharging ice cream can be adjusted with
“Speed Adjuster Screw”. When you turn the screw CLOCKWISE, mass flow
rate will decrease and ice cream discharge will be SLOWER. When you
turn the bolt COUNTER-CLOCKWISE, mass flow rate will increase and ice
cream discharge will be FASTER.
