Refer to either Step A or Step B in this section, as appropriate, to install the conveyor and belt.

A. InstallingtheConveyor-AllovensEXCEPTTandem models

NOTE

Split belt conveyors can only be installed from the end of the oven with the drive motor.

Single-belt conveyor assemblies may be inserted into either end of the oven. If it is to be installed from the end of the oven without the drive motor, the drive sprocket assembly must be removed.

To remove the drive sprocket (if necessary), loosen the set screw

 

 

on the conveyor collar as shown in Figure 2-12. Then, pull the

 

 

sprocket assembly straight out.

2.Continue moving the conveyor into the oven until the frame protrudes equally from each end of the oven (about 18"/ 457mm).

3.Check that the retainers located on the underside of the conveyor frame rest firmly against the lower end plug, as shown in Figure 2-14.

NOTE:

PS360EWB ovens have a retainer bracket that extends the full width of the conveyor frame on both ends of the frame. All other ovens have retainer clips as shown in Figure 2-14, located on the drive (left) side of the frame only.

4.When the conveyor is positioned properly, check for free- dom of movement of the conveyor belt by pulling it for about 2-3 feet (60 to 90 cm) with your fingers. The conveyor must move freely.

5.If the drive sprocket was removed when installing the conveyor, replace it at this time.

6.Install the drive chain between the conveyor drive sprocket and the motor sprocket. To install the chain, it will be necessary to lift the drive end of the conveyor slightly. The drive motor and sprocket are shown in Figure 2-12.

7.Install the conveyor drive motor cover and tighten its hanger screw (on the rear wall of the oven).

8.Check the tension of the conveyor belt as shown in Figure 2-15. The belt should lift between 3-4" (75-100mm). DO NOT OVERTIGHTEN THE CONVEYOR BELT.

NOTE:

If necessary, the belt tension can be adjusted by turning the conveyor adjustment screws, located at the idler (right) end of the conveyor. See Figure 2-15.

This innovative oven combines cutting-edge technology with user-friendly features, making it an ideal choice for restaurants, pizzerias, and foodservice operations that demand efficiency and speed.

Each deck can accommodate multiple pizzas at once, making it an ideal choice for busy establishments where speed is crucial. Operators can load pizzas into both decks simultaneously, significantly reducing cooking times during peak hours.

Another key characteristic of the PS300F is its digital control panel. This user-friendly interface allows operators to set precise cooking times and temperatures, ensuring optimal results every time. The oven also features programmable settings, enabling users to save specific cooking parameters for different types of pizzas, simplifying the process during high-volume service.

Energy efficiency is another important consideration in the design of the PS300F. The oven is constructed with high-quality insulation to minimize heat loss, contributing to lower energy consumption. This makes it not only an environmentally friendly option but also a cost-effective choice for businesses looking to reduce their utility bills.

Durability is a hallmark of the Middleby Marshall brand, and the PS300F exemplifies this commitment to quality. Built with robust materials and designed to withstand the rigors of a busy kitchen, this oven promises longevity and reliable performance.

In conclusion, the Middleby Marshall PS300F is a top-tier pizza oven that brings together innovative technology, efficiency, and durability.
