AIR FLOW

(OPEN TO ROOM)

FIGURE 4. COOLING UNIT SPACE REQUIRED

PLACING COOLING UNIT IN OPERATING POSITION

1.Very carefully, move Cooling Unit back into operating position leaving space around Unit (see Figure 4) as specified in SELECTING LOCATION. MAKE SURE THERE ARE NO KINKS IN COOLING UNIT INLET LINES, AND (IF APPLICABLE) REMOTE CONDENSER AND FAN ASSEMBLY REFRIGERATION LINES.

NOTE: To comply with National Sanitation Foundation (NSF) requirements, Cooling Unit not installed on optional Cooling Unit Stand (P/N 309309-069) must have its base sealed to floor with Dow-Corning RTV 731 or equivalent.

2.Tilt Cooling Unit up to expose bottom of Unit base.

3.Liberally apply silastic sealant such as Dow-Corning (RTV 731) or equivalent on Unit base bottom edges.

NOTE: Do not move Cooling Unit after positioning or seal from Unit base to floor will be broken.

4.Lower Cooling Unit into operating position to complete seal from Unit base to floor. Apply additional sealant around bottom of base. Seal must have a minimum radius of 1/2-inch to prevent cracks and crevices and to ensure a complete seal.

5.Route Cooling Unit water tank overflow hose to permanent floor drain.

6.Seal area around drain and overflow hoses where they exit from Unit using Dow Corning (RTV 731) or equivalent).

PREPARING COOLING UNIT FOR OPERATION

1. Make sure plug in end of Cooling Unit water tank drain hose is secure.

Note: Some Cooling Units are equipped with a water tank water level float control. Open shutoff valve in plain water inlet supply line. Due to slow water fill rate of the water level float control, water tank may be hand filled until water runs out of the water tank overflow hose. CLEAN LOW-MINERAL-CONTENT WATER MUST BE USED WHERE A LOCAL WATER PROBLEM EXIST.

2.Fill water tank with clean water until water starts flowing from water tank overflow hose. USE LOW MINERAL CONTENT WATER WHERE A LOCAL WATER PROBLEM EXISTS.

3.Open shutoff valve in plain water inlet supply line.

4.Adjust primary CO2 regulator (see Figure 2) on CO2 cylinder to a minimum nominal setting of 120-psi or 24-psi higher than highest setting required by the secondary CO2 regulators. Loosen CO2 regulator adjusting screw locknut. Turn adjusting screw to the right (clockwise) until regulator gage registers nominal 120-psi, then tighten adjusting screw locknut.
