3. Installation Preparation – ReadBefore Beginning Installation

For correct and safe installation, please read these instructions completely.
The grounding of electrical equipment such as telephone, computers, etc., to water lines is a common procedure. This grounding may be in the building, or may occur away from the building. This grounding can cause electrical feedback into a water chiller, creating an electrolysis which causes a metallic taste or an increase in the metal content of the water. This condition is avoidable by using the proper materials. Drain fittings which are provided by the installer should be plastic to electrically isolate the chiller from the building plumbing system.

NOTICE Warranty is void if installation is not made in accordance with current instructions.

• Hose sets are not to be used for connecting to water mains.
• Always shut off the valve at the installation/ service area to reduce risk of water damage.
• Thoroughly flush all water lines and fittings of all foreign matter before connecting to chiller.
• If inlet pressure is above 100 psig (0.69 MPa), a pressure regulator must be installed in water supply line. Any damage caused by the water pressure outside its rated pressure is not covered by warranty.

3. Shut off the water supply source and disconnect power to the electrical outlet being used to operate the product before starting installation.
   NOTICE: Mounting hardware to be supplied by customer.

4. 4. It is important to ensure proper ventilation.

5. When mounting in an open area, to ensure proper ventilation, maintain a 4″ (102mm) clearance from cabinet louvers on each side of chiller. When mounting unit in a cavity or behind a wall, maintain a minimum space of 4″ (102mm) on each side, 4″ (102mm) on the top and a depth of 12″ (305mm).

6. Water inlet is 1/4” (6 mm) O.D. tube. Contractor to supply connections as required.

7. Connecting lines to be made of unplated copper. Thoroughly flush all lines to remove all foreign matter before connecting to chiller. If flushing does not remove all particles, a water strainer should be installed in supply line. This chiller is manufactured in such a manner that it does not in any way cause taste, odor, color or sediment problems.

8. Connect chiller to building supply with a shut-off valve and install the in-line strainer between the valve and chiller.

9. Electrical: Make sure power supply is identical in voltage, cycle, and phase to that specified on chiller serial plate. Never wire the compressor directly to the power supply.7.

Installation: Electrical Connection

1. Turn off electrical supply to chiller circuit.
2. Remove the front panel to gain access to electrical box using a 5/16″ (7.9mm) socket wrench or a flathead screwdriver.
3. Rotate the fan to ensure a proper clearance and free fan action.
4. Use 3/8” cable clamp connector or appropriate conduit connector with nut to connect the electrical wire to the unit
5. Connect ground wire (A) to ground screw (provided).
6. Connect the black wire (B) to hot line and connect the white wire (C) to neutral line.
7. Install the front panel to the unit.

Start-Up.

1. Open supply line valve.
2. Purge air from all water lines by operating bubbler valve of fountain to which chiller is connected. Steady water stream assures all air is removed.
3. Turn on electrical supply.

Service

For proper and safe servicing, please read these Caution, Warning instructions completely before servicing.
Note : Disconnect power supply before servicing the unit. All service work must be performed by an authorized service person.

Service: Adjustments

Temperature Control
Factory set for 50ºF ± 5º (10ºC ± 5º) water under normal conditions. For cold water, adjust screw on item no. 12 in clockwise direction.

Service: Inspection/Cleaning

• Inspect the Water Chiller twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc. and reassembly and return to service practices.

Condenser Fan Motor
Visually check and confirm the condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service personnel to check and replace the fan.

Ventilation
Cabinet louvers and the condenser fins should
be periodically cleaned with a brush, air hose or vacuum cleaner. Cleaning should be done twice each year or more frequently if needed due to environment. Excess dirt or poor ventilation can cause no cold water and compressor cycling on the compressor overload protector.

Waterflow
Make sure that the water flow is proper. If water flow is slow, then inspect the filter or in-line strainer for restriction. Replace the filter cartridge if required. Disassemble the in-line strainer and clean if required.

Lubrication
Motors should be lifetime lubricated.

Actuation of Quick Connect Water Fittings
Chiller is provided with lead-free plug which utilizes an O-ring seal. To remove the plug from Chiller, relieve the water pressure, pull the collar towards the fitting and then pull the fitting from the tube. To install the plug, push the fitting straight onto the tubing until it reaches a positive stop, which should be approximately 3/4” (19mm). Refer page 10 for quick connect fittings.
