Location of Ice Machine

The location selected for the ice machine head section must meet the following criteria. If any of these criteria are not met, select another location.

•The location must be free of airborne and other contaminants.

•Self contained air and water cooled - The air temperature must be at least 35°F (1.6°C), but must not exceed 110°F (43.4°C).

•Remote air cooled - The air temperature must be at least -20°F (-29°C), but must not exceed 120°F (49°C)

•Ice Making Water Inlet - Water Pressure must be at least 20 psi (1.38 bar), but must not exceed 80 psi (5.52 bar).

•Condenser Water Inlet - Water Pressure must be at least 20 psi (1.38 bar), but must not exceed

150 psi (10.34 bar). S3300W-HP units allow water pressure up to 350 psig (24.13 bar).

•The location must not be near heat-generating equipment or in direct sunlight and protected from weather.

•The location must not obstruct air flow through or around the ice machine. Refer to chart below for clearance requirements.

•The ice machine must be protected if it will be subjected to temperatures below 32°F (0°C). Failure caused by exposure to freezing temperatures is not covered by the warranty. See “Removal from Service/Winterization”

Important

Manitowoc remote systems are only approved and warranted as a complete new package. Warranty on the refrigeration system will be void if a new ice machine head section is connected to pre-existing (used) tubing or remote condensers or vice versa.

CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES

NOTE: Manitowoc warrants only complete new and unused remote packages. Warranty on the refrigeration system will be void if a new ice machine head section is connected to existing (used) tubing or condensers.

Line Set Length

The maximum length is 100' (30.5 m).

The ice machine compressor must have the proper oil return. The receiver is designed to hold a charge sufficient to operate the ice machine in ambient temperatures between -20°F (-28.9°C) and 120°F (49°C), with line set lengths of up to 100' (30.5 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m). The maximum drop is 15' (4.5 m).

!	Caution
If a li ne set has a rise followed by a drop, another
rise cann ot be mad e. Likew ise, if a li ne se t h as a
drop fo llowed by a	rise,	another drop cannot be
made.

Calculated Line Set Distance

The maximum calculated distance is 150' (45.7 m).

Line set rises, drops, horizontal runs (or combinations of these) in excess of the stated maximums will exceed compressor start-up and design limits. Thiswill cause poor oil return to the compressor.

Make the following calculations to make sure the line set layout is within specifications.

1.Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise. (Example: A condenser located 10 feet above the ice machine has a calculated rise of 17 feet.)

2.Insert the measured drop into the formula below. Multiply by 6.6 to get the calculated drop. (Example. A condenser located 10 feet below the ice machine has a calculated drop of 66 feet.)

3.Insert the measured horizontal distance into the formula below. No calculation is necessary.

4.Add together the calculated rise, calculated drop, and horizontal distance to get the total calculated distance. If this total exceeds 150' (45.7 m), move the condenser to a new location and perform the calculations again.

Maximum Line Set Distance Formula

Step 1

Measured Rise ____ X 1.7 = ______Calculated Rise (35 ft. Max)

Step 2

Measured Drop ____ X 6.6 = ______Calculated Drop (15 ft. Max.)

Step 3

Measured Horizontal Distance = _________Horizontal (100 ft. Max.) Distance

Step 4

Total Calculated Distance = ________Total Calculated (150 ft. Max.) Distance

LENGTHENING OR REDUCING LINE SET LENGTHS

In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser.

The quick connect fittings on the line sets are equipped with Schraeder valves. Use these valves to recover any vapor charge from the line set. When lengthening or shortening lines follow good refrigeration practices, purge with nitrogen and insulate all tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (143g) of vapor refrigerant charge in each line.

CONNECTING A LINE SET
1.	Remove the dust caps from the line set,
	condenser and ice machine.
2.	Apply refrigeration oil to the threads on the quick
	disconnect couplers before connecting them to
	the condenser.
3.	Carefully thread the female fitting to the
	condenser or ice machine by hand.
4.	Tighten the couplings with a wrench until they
	bottom out.
5.	Turn an additional 1/4 turn to ensure proper
	brass-to-brass seating. Torque to the following
	specifications:
	Liquid Line		Discharge Line
	10-12 ft lb.		35-45 ft lb.
	(13.5-16.2 N•m)		(47.5-61.0 N•m)
6.	Check all fittings and valve caps for leaks.
7.	Make sure Schraeder cores are seated and
	Schraeder caps are on and tight.
