Section 2 - Set Up Before proceeding, be sure all power is off 2.1 Location Locate the chiller on a strong, level surface. Insure easy access to the top cover and position the chiller for unobstructed air flow through the front and rear screens. The front wheels can be locked to keep the chiller in place while in use. Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger diameter wire. If possible, be close to the power distribution panel.
IMPORTANT! Chillers equipped with a high pressure positive displacement pump have a pressure regulator inside of the chiller and a pressure gauge on the control panel. To access this regulator, remove the rear air grille. The valve is located to the right. On models 6107 & 6705, 6155 the regulator is located center point, upper grille (rear). The Pressure Valve is FACTORY ADJUSTED to 40psi.
Section 3 - Operation 3.1 Power Requirements Caution! Be sure that the power supply is the same voltage as specified on the nameplate With the chiller plugged in (before pressing the POWER ON button), the display responds by showing standby (....). If there is no response, check that the circuit breaker on the rear of the chiller is in the ON position. An extension cord is not recommended.
3.4 Setting the Readout High Limit This feature limits the readout setability so the operating temperature setting cannot easily be set above the High Limit you select. It is not an over temperature feature which shuts off the chiller. To set the readout High Limit: 1. Press and hold the Set/Menu button until the display reads “UNITS”. 2. Turn the Setting Adjustment knob until the display reads “HI-L”. 3. Press the Set/Menu button, enter the desired value using the Setting Adjustment knob. 4.

Section 5 - Maintenance Prepare a schedule to perform these specific maintenance tasks at their recommended intervals. 5.1 Standard Magnetic Drive Centrifugal Pump Motor When the chiller is used continuously, this pump motor must be oiled every 6 months with SAE 20 oil. Press the POWER OFF and unplug the chiller. Remove the rear access panel to gain access to the two oil ports located on the pump motor. Do not apply excessive amounts of oil.
