ℹ️ NOTE: If unit is to be transported, it is advisable to leave the unit secured to the plywood shipping base.
? ATTENTION: DO NOT LAY UNIT ON ITS SIDE OR BACK.
Selecting/Preparing a Counter Location
ℹ️ NOTE: The chiller should only be installed in a location where it can be overseen by trained personnel.
- The chiller is designed to sit on a flat, supported surface capable of supporting a minimum weight of 500 lbs (227 kg). Select a location that is in close proximity to a properly grounded electrical outlet that meets the requirements shown in the Specifications section found on pages 4-5.
- Select a location for the syrup pumps, CO₂ tank, syrup containers, water filter (recommended), and remote carbonator. Please see General System Overview on page 6 for reference.
- When the chiller is to be permanently bolted to the countertop, use sealant to seal chiller base to countertop.
ℹ️ NOTE: NSF listed units must be sealed to the counter.
- Condenser air is drawn in from the back grill located on the bonnet and discharged out the top of the bonnet. A minimum clearance of 15 inches (380 mm) over the top and a 6 inches (152 mm) behind the unit must be maintained to provide for proper air flow and circulation.
Diagram showing clearances: 15 inches overhead, 6 inches behind.
- ? ATTENTION: Failure to maintain specified clearance will cause the compressor to overheat and will result in compressor failure.
- To mount the chiller in the designated location, cut the necessary holes in the countertop.
Chiller Installation
- Install the unit onto the counter.
- Remove the bonnet from the chiller by lifting up.
- Route power cord from control box to outlet.

Diagram showing connection of tubing (B, C) from chiller outlets to dispenser. A indicates Oetiker Clamp.
ℹ️ NOTE: Make sure the overflow tube is not covered to allow water from the water bath tank to escape as needed.
- Remove cap from fill hole and insert a funnel into the fill hole.
- ? ATTENTION: Carefully read this before filling the water bath tank. In order to optimize the maximum performance of the chiller, the following steps and warnings MUST be adhered to. To ensure proper function of the electronic ice bank control a total dissolved solids (TDS) of 100-300 ppm or an E.C. measurement between 156 and 468 µS/cm is required. Below 100 ppm or 156 µS/cm, the compressor will not work properly and above 300 ppm or 468 µS/cm could cause the lines to freeze. The necessary TDS may be achieved using tap water; however, Lancer recommends using a mixture of 1 tbsp of baking soda for every 5 gals. (19 L) of distilled water.
- Carefully pour water into the water bath tank until water flows out of the overflow tube at the front of the unit, then replace the cap.
- Plug unit power cord into a grounded electrical outlet to power on and begin building an ice bank.
? ATTENTION: The water bath compartment must be filled with water before connecting the unit, otherwise the compressor fan may not operate properly. DO NOT use Reverse Osmosis (RO) or purified water.
⚠️ WARNING: Never energize the machine if there is any trace of damage. Contact Lancer Customer Service for assistance.
⚠️ WARNING: The chiller must be properly electrically grounded to avoid serious injury or fatal electrical shock. The power cord has a three-prong grounded plug. If a three-hole grounded electrical outlet is not available, use an approved method to ground the unit. Follow all local electrical codes when making connections. Each chiller must have a separate electrical circuit. Do not use extension cords. Do not connect multiple electrical devices on the same outlet.
