Frequently Asked Questions - GB2 Perlick

What is the Perlick GB2 used for?

The GB2 is a glycol bath that circulates chilled glycol to maintain beer temperature in long-draw dispensing systems. It works in conjunction with a separate refrigeration deck (RD series) to cool the glycol.

What are the electrical requirements for the GB2?

The GB2 requires 120 V, 60 Hz, 1 phase power. It has a RLA of 12.6 A and MCA of 13.6 A. A 20 A fuse is recommended. It comes with a 8 ft, 20 A cord with NEMA 5-20P plug.

How do I install the GB2 with a refrigeration deck?

Place the deck and bath within 100 feet of each other. Connect coolant lines (feed and return) between the deck and bath using the provided connector kit. Wire low-voltage control wires (black and white) from the deck to the bath transformer (blue and yellow). Ensure dedicated circuits per local codes.

What type of coolant should I use?

Only use Perlick approved coolant solution (#63299-1), a pre-mixed food-grade propylene glycol with distilled water at 30% concentration. Other solutions void the warranty.

How do I fill and start the system?

Fill the 12-gallon reservoir with Perlick coolant. Turn on pump #1 (heat removal) first to purge air from the deck lines. Continue adding coolant until return line shows no bubbles. Then start individual recirculating pumps. Check all connections for leaks. Final fill to within 2 inches of the top.

What is the temperature controller set to?

The factory-set cut-out temperature is 30°F with a hysteresis of 2°F. The controller has a 1-minute anti-short-cycle delay. Do not adjust parameters unless necessary.

How do I interpret the digital controller alarms?

Common alarms: P1 (room probe failure) – continues operation with 5-min cycles; HA (high temperature) – exceeds max alarm for 15 min; LA (low temperature) – below min alarm for 15 min. See manual for actions.

What maintenance does the GB2 require?

Quarterly: check coolant level and concentration (30% minimum) using a refractometer; clean the condenser fins with a brush or compressed air. More often in dusty environments.

Can I add flash chill coils to the GB2?

Yes, up to 12 flash chill circuits can be installed. Use the Flashchill Connector Kit (#68455). Follow instructions to splice into product lines and glycol lines. The coils lower product temperature up to 6°F on continuous pour.

What are the replacement pump specifications?

The heat removal pump (pump #1) is a rotary vane, brass pump (#67509) with 140 GPH / 130 PSIG. Recirculating pumps (#2-4) are rotary vane, brass (#63291-1) with 100 GPH / 130 PSIG. Motors are carbonator style (#63293).

PRODUCT DESCRIPTION

Power Paks have always been an integral part of a Perlick ArcticPOUR Beer System. The ArcticPOUR Series Refrigerated Decks and Glycol Baths product line has been developed to satisfy longer beer runs, removal of heat from the indoors and flash-chilling of products.

The Refrigerated Deck is a sealed refrigeration system that can be located anywhere, including outdoors. The Glycol Bath consist of a 12 gallon resevoir with one heat removal pump and up to three additional pumps for maintaining product temperature from the walk-in cooler to the dispensing stations. In addition, up to 12 flash-chill circuits can be installed within the bath for flash-chilling for serving at lower temperatures. The heat removal pump circulates coolant solution (food grade propylene glycol with distilled water) from the bath to the refrigerated deck to maintain the bath temperature. The three additional re-circulating pumps circulate coolant solution from the bath through the insulated beverage housing from the walk-in cooler to the dispensing station(s) and back, maintaining the desired dispensing temperature at the faucet. The Glycol Bath can also include from 1 to 12 flash-chill tubes for lowering product temperatures up to 6 degrees F on a continuous pour. The Refrigerated Decks employ a direct expansion refrigeration system with a brazed plate heat exchanger for maximum efficiency and performance.

The Outdoor Refrigeration Decks includes a crankcase heater, condenser fan controls and shrouds for use in any conditions. The Glycol Baths incorporates 1/3 hp ball bearing, maintenance-free motor(s) with a 140 gph, 130 psig positive displacement pump for heat removal and 100 gph, 120 psig positive displacement pump(s) for optimum performance. In addition the Glycol Bath uses a digital temperature control for maintaining optimal bath temperature and displaying the temperature.

INSTALLATION

IMPORTANT SAFETY WARNINGS!

• Follow all National and Regional codes
• Read Operation/Installation Manual carefully before attempting to install, operate or maintain the product.
• Protect yourself and others by observing all safety

information.

• Electrical hazards exist and can cause injuries if not serviced by properly trained personnel.
• Failure to comply with instructions could result in personal injury and/or property damage!
• Retain instructions for future reference.

NOTE: Air-cooled Power Paks must be installed in areas with adequate ventilation to maintain ambient temperatures, achieve performance specifications and satisfy warranty requirements.

INSTALLING THE POWER PAK

Prior to installing a Refrigerated Deck and Glycol Deck, it is imperative that the method of connecting them to the electrical service has been determined. Ensure that the electrical service to power these systems will handle the load requirements. See the product specifications or ID plate on the equipment for Electrical Load Requirements. All units with RLA greater than 16 amps and a MCA of greater than 20 amps should be hard-wired to electrical service by a certified Electrician.

CONNECTING REFRIGERATION DECK AND GLYCOL BATH

• Determine the ideal placement of the Refrigeration Deck and Glycol Bath. It is recommended that the distance between the Refrigeration Deck and Glycol Bath does not exceed 100 feet (contact the factory if longer distances are required). NOTE: If the Refrigerated Deck is to be located on top of the walk-in cooler or in an enclosed area, it is imperative that proper ventilation is provided to prevent system failure due to overheating. Inadequate ventilation will void warranty.
• Place the Refrigeration Deck on a level surface and fasten in place using included mounting tabs if needed on Deck base. REMINDER: Allow a minimum of six inches of clearance on louvered ends of the cabinet for proper airflow. Allow accessibility room on the top of the cabinet as well as the front of the cabinet for serviceability.
• Mark Coolant Connector Lines for feed line and return line. Use compressed air to blow through the lines to identify.
• Route Coolant Connector Line Set from Refrigeration Deck to Glycol Bath.
• Remove top cover and front panel on Refrigeration Deck. Remove Access Hole Shroud (if equipped)

CONNECTING REFRIGERATION DECK AND GLYCOL BATH (cont.)

• Make coolant line connections and clamp using included Oetikers (Inlet fitting is located on the outside of the cabinet, outlet fitting is located inside the cabinet). Insulate the glycol lines completely to avoid condensation and unnecessary heat gain. (Ensure that the feed line is connected to the inlet fitting and the return line to the outlet fitting).
• Connect Low Voltage wires to the two wires with bell connectors on them [(1) Black wire, (1) White wire]. See Wiring Diagrams (pages 11-13) for proper connections.
• Connect Refrigeration Deck to proper power source. Permanently connected units should be wired per the wiring diagram and circuit should be sized according to the I.D. plate's electrical specifications. The circuit should be sized in accordance with the electrical requirements of the unit as well as in compliance with all National and Local codes (codes may require a separate disconnect for these units). NOTE: Electrical circuit should be a dedicated circuit for use only with the Refrigeration Deck.
• Make Coolant Line connections on Glycol Bath, one to pump outlet, the other to bath return tube and clamp using included Oetikers (Coolant Connector feed line).
• Remove the top front panel on the bath and the electrical box front cover.
• Connect low voltage wires to the low voltage transformer secondary wires with bell connectors (Blue and Yellow wires).
• Ensure power switches for the pump motor(s) are in the OFF position. (Check transformer to ensure the leads are connected to the low voltage side of the transformer). Make the electrical connections per the wiring diagram. The circuit should be sized in accordance with the electrical requirements of the unit as well as in compliance with all National and Local Codes (codes may require a separate disconnect for these units). NOTE: Electrical circuit should be a dedicated circuit for use only with the Glycol Bath.
  • Re-install Electrical Box Cover.

CONNECTING TO FLASH CHILL COILS

If the Glycol Bath includes flash chill coils, then follow these instructions for proper connections:

- Locate Glycol Bath in-line with convenient point along the trunk housings to splice into the product lines and glycol feed line within the trunk housing (this location could be inside the

walk-in cooler, immediately outside the walk-in cooler or anyplace along the trunk housing up to the point of connection to the dispensing head).

- To make the proper connections, Flash Chill Connector kit 68455 is required. Using instructions included with kit 68455 make the necessary connections for each product tube and coolant line.

GLYCOL BATH INSIDE WALK-IN COOLER

• Connect and clamp incoming product lines to inlet of flash chill tube(s). Connect and clamp outgoing product lines to outlet of flash chill tube(s). Using included coolant loop coils from kit 68455, (pick the correct size based on the number of flash chill tubes) hook up to glycol lines (see kit instructions 68455-INS).
• Tape and insulate the coolant loop and outgoing product tubes to prevent condensation on heat gain into the newly flash chilled product lines. The product lines should be taped to the coolant lines and then combined should be fully insulated to the trunk housing insulation.

GLYCOL BATH LOCATED ALONG THE TRUNK HOUSING.

In this scenario, the pump to maintain the product temperature within the trunk housing is going to go from the pump outlet to the flash chill coolant loop, then from the flash chill coolant loop to the trunk housing coolant line to the dispensing head, then back through the trunk housing to the walk-in cooler and finally back to the Glycol Bath.

• If the trunk housing is located along the path of the trunk housing, then the trunk housing must be spliced, similarly to dropping product lines at a dispensing head, except in this case all the product lines are being dropped to the flash chill coils along with the feed line of the glycol circuit.
• Once all coolant and product connections are made using the included oetiker clamps, product lines are securely taped to the coolant lines and then all product lines and coolant lines are insulated using the included insulation to prevent condensation and heat leak.

CONNECTING TO A TRUNK HOUSING

• Inspect pump outlet port for cleanliness

• Cut supplied coolant tubing (#54588) to required length to reach from Glycol Bath to Trunk Housing connection point.

• Cut tubular insulation (#C12700) in half and install over previously cut coolant tubing.

• Take Oetiker clamps (#54871-210) and install over coolant tubing ends.
• Push coolant lines, one each over pump outlet barbed fitting and bath return port on bath cover.
• Position Oetikers over tube ends and clamp securely.
• Slide tubular insulation tightly against connection points. Use insulation tape as necessary to ensure an air tight seal to prevent excessive heat gain or condensation problems.
• Drill a 3-1/2" diameter hole in walk-in cooler to accommodate coolant lines.
• Slide large insulation (#57478) over remaining coolant tubing exposed to warm air conditions including inside walk-in cooler from Bath to Trunk Housing connection point. Seal and tape all seams to prevent excessive heat gain or condensation problems.
• Slide coolant lines though 3-1/2" hole previously cut in walk-in cooler wall.
• Position Trunk Housing coolant lines and Coolant Connector kit lines in horizontal position, to alleviate condensation runoff into Trunk Housing.
• Cut Trunk Housing coolant lines with tubing cutter to ensure clean burr-free ends.
• Install Oetikers over plastic coolant lines coming from bath. Slide lines over coolant lines from trunk housing and clamp Oetikers.
• Seal around hole where insulated coolant lines pass through walk-in cooler wall to ensure an air tight seal to prevent walk-in cooler problems as well as condensation.

CONNECTING TRUNK HOUSING COOLANT LINES TO DISPENSING HEAD

• Position the trunk housing so that beverage lines can be connected with a minimum cutting.
• Split trunk housing approximately 12 inches from the end to allow working room for the connections.
• Cut and deburr copper coolant lines coming from trunk housing and dispensing head. Stagger the lengths.
• Connect trunk housing coolant lines to dispensing head coolant lines using installation kit included with dispensing head connecting kit. Ensure that clamps are properly installed to guarantee a leak-free connection.
• Make product line connections from trunk housing to dispensing head.
• Pressurize lines to ensure that they are leak-free.
  • After system start-up, tape product lines to coolant

lines and re-insulate product lines, gluing and taping all the seams.

SYSTEM START-UP

Use only Perlick Approved Coolant Solution (#63299-1), all other solutions and mixtures will void the Perlick warranty. The Coolant Solution has been pre-mixed for optimum performance and wear protection. The Glycol Bath resevoir holds approximately 12 gallons of solution. It takes approximately 1 gallon of Coolant Solution to fill every 60 feet of Perlick Trunk Housing.

• Never operate the circulating pumps without coolant in the resevoir.
• Fill resevoir with Perlick Coolant Solution.
• Turn Pump Switch #1 to the ON position. Coolant solution level will begin to drop in resevoir. It is filling the Coolant Connector Line set between the Glycol Bath and the Refrigeration Deck.
• Continue adding Perlick Coolant Solution until no air bubbles are apparent from the Coolant return line. NOTE: Never allow for the Coolant level in the resevoir to drop below the pump inlet tube. Allowing the level to drop below the inlet will allow air into the lines.
• Check glycol line connections at both the Bath and the Refrigeration Deck for leaks.
• Refrigeration Deck should be running if the glycol is above the set point temperature.
• Turn on power to each individual pump motor and fill all other glycol lines, adding glycol to bath as needed to maintain proper glycol level within the reservoir. Check all other glycol connections for leaks.
• Re-install Refrigeration Deck front panel and Top Cover.
• Fill reservoir to within 2 inches of the top edge of the tank. Watch return lines for additional air bubbles as this may signify additional Coolant Solution may need to be added.
• Thoroughly check all field connection points for leaks.
• Monitor Glycol Bath Temperature read-out to ensure Refrigeration Deck is working properly. Dependent on length of trunk housing run(s) and surrounding ambient conditions, these factors will determine how long it takes for the system to cut-out on the temperature control. The control is factory programmed to cut-out at 30°F with a hysteresis of 2°F. The control has also been programmed to prevent short cycling and requires one minute of off time before it will restart.
  • Re-install Glycol Bath Cover.

DIGITAL TEMPERATURE CONTROLLER

The Glycol Bath comes equipped with a factory programmed electronic thermostat with display. The thermostat has numerous factory settings, which should never be adjusted or tampered with to ensure proper operation of the System. The thermostat has been factory programmed to cut-out at 30^ F with a hysteresis/differential of 2^ F.
