PART DESCRIPTIONS AND CODE
Equipment shown above: 15 inch square syrup press
Configuration shown: 10 hollow frames / 9 plates
Model number shown: SR010-100915XX
No Qty Part description Part code
21 15 in. stainless steel restraining plate for square press SR405-151632S4
Note that the RESTRAINING PLATE is available as an OPTION.
This plate allows you to use only part of your syrup press when filtering maple syrup.
It is helpful to use this restraining plate when the amount of syrup to filter is small or in anticipation of a short
filtration day.
The advantages of using the restraining plate include:
• Saving on the amount of filter paper and filter powder used,
• Reducing equipment cleaning time as fewer plates and hollow frames are used,
• Reducing syrup los.
You can find the installation procedure for this restraining plate here.
1. Select a plate with sleeves from the syrup press (Illustration 3 No. 3).
• The selected plate should ideally be located in the middle section of the press.
2. Place this plate slightly away from the hollow frame (Illustration 3 No. 1) which is located on the side opposite the jack
(Illustration 3 No. 4) .
• Space it so that the restraining plate can be inserted freely.
3. Insert the restraining plate (Illustration 3 No. 2) between the plate with sleeves and the selected hollow frame. Also
insert the filter papers as described in Section 4.4 FILTER PAPERS, HOLLOW FRAMES, PLATES AND CONNECTORS.
4. Close the syrup press with the pneumatic jack (Illustration 3 No. 4), applying moderate pressure to the press components.
Notes on the plate with sleeves ADJACENT to the restraining plate
The sleeves are factory fitted tight when fitted to the plates. Although they appear fixed in their opening, they
will move slightly under the pressure of the jack when the press is closed. Despite this slight forced movement
in their opening, you will be able to continue to use this plate with sleeves on your next workday, whether you
use the restraining plate or not.
In addition, when using your restraining plate in the future, it is recommended that you use this same - slightly
displaced – plate with sleeves as an immediate neighbouring component to your restraining plate.
RESTRAINING PLATE: COMPONENT SET UP SEQUENCE
• It is important to follow the component SET UP SEQUENCE taking into account the position of
the hollow frame (1) and the jack (4) on the syrup press.
• The restraining plate (2) must be on the same side of the hollow frame (1) as the jack (4).

Lapierre Equipment | SYRUP PRESS | USER MANUAL | Version 01 - December 2021
SECTION 4 START-UP AND OPERATION PROCEDURES
4.1 FEED VALVE
Check that the feed valve of the syrup water jacketed tank is open and that there is a sufficient supply of syrup.
4.2 DIAPHRAGM PUMP
If you are using a diaphragm pump, do the following.
• Air duct: For each use, insert a drop of oil into the air duct before filtering.
• Repeat after cleaning and before storing the equipment for a long period of time. This will help ensure the
equipment will function optimally the next time it is used.
4.3 GEAR PUMP
If you are using a gear pump, do the following.
• Clean the pump with warm or hot water each time it is used.
• Lubrication is also recommended during the same maintenance operation.
4.4 FILTER PAPERS, HOLLOW FRAMES, PLATES AND CONNECTORS
• Insert one or two filter papers between each of the press components, i.e., blocks, hollow frames and plates.
- You must also insert one or two filter papers on the restraining plate, if you are using one.
• Check that all blocks, hollow frames and plates are installed as specified on Pages 8 and 10 under GUIDES
FOR THE CORRECT INSTALLATION OF BLOCKS, HOLLOW FRAMES AND PLATES. Also check that the filter
paper holes are aligned with the holes in the blocks, hollow frames and plates of the press.
When in operation, A SYRUP PRESS IS EXTREMELY HOT : approximately 230 ˚F (110 ˚C).
The piping used must be rated for this temperature and withstand pressures up to 200 psi
(14.06 kgf/cm2). Contact with a hose or its rupture could cause very severe burns to the operator
and any other persons in the vicinity of the equipment. Be very careful with children, family
members, guests and pets.
MOVE THE EQUIPMENT WHILE IT IS RUNNING ONLY IF NECESSARY, first switch off the pump,
disconnect the power cord and check that the floor is level, perfectly stable, and unobstructed
throughout the intended journey.
Hot syrup can cause severe burns. Always wear SAFETY GOGGLES and HEAT RESISTANT
GLOVES AND CLOTHING when working with this equipment.

17
Lapierre Equipment | SYRUP PRESS | USER MANUAL | Version 01 - December 2021
SECTION 4 Start-up and operation procedures (continued)
• Ensure that the seals in the quick connectors (Illustrations 1 No. 15, 2 Nos. 4 and 11) are flexible and free from
cracks. Then firmly attach the connecting pipes.
4.5 SYRUP WATER JACKETED TANK
If you are using a syrup water jacketed tank, make sure the water level covers the heating element(s) before
turning them on.
4.6 SYRUP TEMPERATURE
• You can start filtering when the syrup has reached a temperature of 185 ˚F (85 ˚C).
• If the syrup temperature drops below 180 ˚F (82 ˚C), turn the pump off or into recirculation mode. Wait until
the temperature reaches 185 ˚F (85 ˚C) again before restarting the maple syrup filtration operation.
4.7 FILTER POWDER
Adding Dicalite or Celite type filter powder can help increase the speed and quality of filtration.
Add the powder directly into the syrup and stir to distribute the powder evenly.
It is recommended that you return the first 3 gallons of syrup (15 litres) to your container to bring the filter
papers to optimum performance with the powder being filtered.
When this is complete, turn the pump off and move the outlet hose from the press to the syrup container. Then
turn the pump on again and proceed with the filtration.
Quantity to use
The amount of powder to use can vary depending on several characteristics of your sugar bush. These include
slope, soil type, geographic orientation, size, tree variety composition, percentage of sugar maples and the
current period of the season. For example, early season is a concern for filtration in terms of sediment quantity,
while late season is a concern for overall sap quality. The amount of powder to use will naturally be influenced
by these variables.
It is important to determine the correct amount of powder to use for optimum efficiency. The larger the size of
the press, the more plates there will be, and the more powder you need to use. That said, trial and error is still
the most effective technique for determining the amount of powder to use for your sugar bush. However, as a
point of clarification, consider that the amount of powder in the filters is considered satisfactory when it covers
the full surface of the press filters.
PRESSURE OVER 80 PSI (5.63 kgf/cm2) ON THE FILTER PAPER could cause it to rupture. The
leakage of high temperature syrup could in turn cause burns of varying degrees to the user or
any other person in the vicinity of the equipment.

4.8 SYRUP LEAKAGE
If syrup leaks between the hollow frames and plates during filtration, first turn off the pump. Then apply additional,
but not excessive, pressure to the press components using the pressure adjustment handles on the 7 in. or 10 in.
presses (Illustration 1 No. 8) located at the end of the press, or the jack (Illustration 2 No. 18) on the 15 in. presses,
also located at the end of the press. Restart the filter operation and repeat the sequence as necessary until the
flow has stopped.
4.9 RECOVERY DRAIN
This drain is used to collect residual syrup in the syrup press after the workday (see Illustration 2-C).
