CAUTION: All packing elements (plastic bags, carton boxes and wood pallets) should be kept outside the reach of children, as they are a source of potential hazard.

Installation

(1) LOCATION OF ICE MACHINE

This ice maker is not designed for outdoor operation. The icemaker should not be located next to ovens, grills or other high heat producing equipment.

The SPIKA machines are designed to operate at room temperature between 41ºF (5ºC) and 109.4ºF (43ºC). There may be some difficulties in ice slab removal under the minimum temperatures. Above the maximum temperature, the life of the compressor is shortened and the production is substantially lower.

The air cooled SPIKA NG (undercounter) ice makers take the air through the front section, and drive it off through the lateral, back and also front louvers due to their new oblique condenser structure and placement. Do not place anything on the top of ice maker or facing the front grille. In case the front grille is either total or partially obstructed, or due to its placement it receives hot air from another device, we recommend, in case it is not possible to change the location, to install a water cooled machine.

2

USER MANUAL SPIKA

The air cooled SPIKA MS (modular) ice makers take the air through the back section and drive it off through the two lateral louvers. In the case it is not possible to respect the minimum distances recommended (see the picture in point 3) for these machines we recommend to install a water cooled unit.

The location must allow enough clearance for water, drain and electrical connections in the rear of the ice machine. It is important that the water inlet piping do not pass near sources of heat so as not to lose ice production.

(2) LEVELING THE ICE MACHINE

Use a level on top of ice machine in order to ensure the equipment is perfectly leveled.

Only for SPIKA NG (undercounter) machines:

Screw the leveling legs onto the bottom of the ice machine as far as possible. Move the machine into its final position.

Use a level on top of the ice machine. Turn each foot as necessary to level the ice machine from front to back and side to side.

NOTE: An optional 3 1/2’’ (90mm) caster assembly is available for use in place of the legs. Installation instructions are supplied with the casters.

(3) MINIMUM DISTANCE TO OBSTACLES

The minimum clearance values you can see below are recommended for efficient operation and servicing.

(5) WATER SUPPLY

The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product (mainly in water cooled units). It also will have a remarkable influence on the appearance, hardness and flavor of the ice.

Local water conditions may require treatment of the water to inhibit scale formation, improve taste and clarity. If you are installing a water filter system, refer to the installation instructions supplied with the filter system.

Use a flexible food grade hose.

Pressure should be between 14 and 85 psi (1 and 6 bar). If pressure overpasses such values, install a pressure regulator.

ATTENTION: The machine shall be plumbed (with adequate backflow protection) according to applicable Federal State and local regulations.

(6) DRAINAGE

Drainage should be located below the level of the machine, at 5,9’’ (150 mm) minimum.

It is convenient that the drainage pipe is 1,18’’ (30 mm) inside diameter and with a minimum gradient of 0,36’’/ft (3 cm/ meter), see figure.

Damages due to the lack of maintenance and cleaning operations are not included on the warranty.

(3) Sequence of Operation

FOR UNDERCOUNTER MODELS:

Initial Start-up: It’s recommended that the first time the machine is started (or the water tray has been emptied) it begins with the harvest sequence to ensure the water tray is filled.

Freeze sequence: The compressor is energized. The timer G2 de-energizes the hot gas valve, so the evaporator begins to freeze. The timer G2 energizes the water pump so the water circulates from the water tray to the upper distributor, flowing through each cube cell, where it freezes.

Harvest sequence: The compressor will continue energized. The timer G2 energizes the hot gas valve during a certain time. The timer G3 at the same time energizes the water inlet valve during a certain time to fill the water tray with the appropriate quantity of water. The ice slab slides off the evaporator and into the bin. After this, the freeze sequence starts again.

When storage bin is full the stock thermostat detects a low temperature and the machine shuts off at the end of the freeze sequence. The ice machine remains off until enough ice has been removed from the storage bin and the stock thermostat doesn’t detect this low temperature.

FOR MODULAR MODELS:

Initial Start-up: The pump and the drain electrovalve are energized during 30 seconds to empty the water tray preventing the scale build-up in water. Then the pump and the drain electrovalve are de-energized, and the water inlet valve is energized filling the water tray until the water level sensor detects the water reaches the appropriate level. Then the freeze sequence starts.

Freeze sequence: The compressor is energized and the water pump is energized after 30 seconds. The water inlet valve is also energized at the same time that the water pump to replenish water level and then de-energized. The compressor and water pump will continue energized until the thickness sensor detects the thickness of the ice slab is the appropriate. Then the harvest sequence starts.

9

USER MANUAL SPIKA

Harvest sequence: The compressor will continue energized. The hot gas valve is energized throughout the harvest phase to divert hot refrigerant gas into the evaporator. The water pump and the drain electrovalve are energized during 45 seconds to empty the water tray and remove mineral deposits. After this (water pump and drain electrovalve deenergized) the water inlet valve is energized filling the water tray until the water level sensor detects water reaches the level. The ice slab slides off the evaporator and into the bin. The momentary opening and re-closing of the shield indicates the harvest sequence has finished and goes to the freeze sequence.

When the storage bin is full, the ice shield is held open during more than 30 seconds and the machine shuts off. The ice machine remains off until enough ice has been removed from the storage bin to allow the ice shield swings back to the operating position

Maintenance and Cleaning Procedures

It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition.

Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. This chemical dissolves mineral build up that forms during the ice making process.

Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized.

The ice machine’s water system should be cleaned and sanitized at least twice a year. CAUTION: Do not mix Ice Machine Cleaner and Sanitizer solutions together.

WARNING: Wear rubber gloves and safety goggles when handling Ice Machine Cleaner or Sanitizer. WARNING: Unit should always be disconnected during maintenance/cleaning procedures.

CLEANING WATER DISTRIBUTION SYSTEM
