Water Service/Drains

WATER SUPPLY

Local water conditions may require treatment of the

water to inhibit scale formation, filter sediment, and

remove chlorine odor and taste.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

• Do not connect the ice machine to a hot water

supply. Be sure all hot water restrictors installed for

other equipment are working. (Check valves on

sink faucets, dishwashers, etc.)

• If water pressure exceeds the maximum

recommended pressure, 80 psig (5.5 bar) obtain a

water pressure regulator from your Manitowoc

distributor.

• Install a water shut-off valve for ice making potable

water.

• Insulate water inlet lines to prevent condensation.

DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to

prevent drain water from flowing back into the ice

machine and storage bin:

• Drain lines must have a 1.5-inch drop per 5 feet of

run (2.5 cm per meter), and must not create traps.

• The floor drain must be large enough to

accommodate drainage from all drains.

• Run separate bin and ice machine drain lines.

Insulate them to prevent condensation.

• Vent the bin and ice machine drain to the

atmosphere.

Important

If you are installing a Manitowoc water filter

system, refer to the Installation Instructions

supplied with the filter system for ice making

water inlet connections.

32 Part Number 80-0111-9 6/11

COOLING TOWER APPLICATIONS

Water Cooled Models Only

A water-cooling tower installation does not require

modification of the ice machine. The water regulator

valve for the condenser continues to control the

refrigeration discharge pressure.

It is necessary to know the amount of heat rejected,

and the pressure drop through the condenser and

water valves (inlet to outlet) when using a cooling

tower on an ice machine.

• Water entering the condenser must not exceed

90°F (32.2°C).

• Water flow through the condenser must not

exceed 5 gallons (19 liters) per minute.

• Allow for a pressure drop of 7 psig (.48 bar)

between the condenser water inlet and the outlet

of the ice machine.

• Water exiting the condenser must not exceed

110°F (43.3°C).

Maintenance

Ice Machine Inspection

Check all water fittings and lines for leaks. Also, make

sure the refrigeration tubing is not rubbing or vibrating

against other tubing, panels, etc.

Do not put anything (boxes, etc.) in front of the ice

machine. There must be adequate airflow through and

around the ice machine to maximize ice production

and ensure long component life.

Exterior Cleaning

Clean the area around the ice machine as often as

necessary to maintain cleanliness and efficient

operation.

Sponge any dust and dirt off the outside of the ice

machine with mild soap and water. Wipe dry with a

clean, soft cloth.

A commercial grade stainless steel cleaner/polish can

be used as necessary.

Cleaning the Condenser

!Warning

Disconnect electric power to the ice machine at

the electric service switch before cleaning the

condenser.

!Caution

If you are cleaning the condenser fan blades with

water, cover the fan motor to prevent water

damage.

AIR-COOLED CONDENSER

A dirty condenser restricts airflow, resulting in excessively

high operating temperatures. This reduces ice production

and shortens component life. Clean the condenser at least

every six months. Follow the steps below.

1. The washable aluminum filter on self-contained air-

cooled ice machines is designed to catch dust, dirt, lint

and grease. This helps keep the condenser clean.

Clean the filter with a mild soap and water solution.

2. Clean the outside of the condenser with a soft brush or a

vacuum with a brush attachment. Clean from top to

bottom, not side to side. Be careful not to bend the

condenser fins.

3. Shine a flashlight through the condenser to check for dirt

between the fins. If dirt remains:

A. Blow compressed air through the condenser fins

from the inside. Be careful not to bend the fan

blades.

B. Use a commercial condenser coil cleaner. Follow

the directions and cautions supplied with the

cleaner.

4. Straighten any bent condenser fins with a fin comb.

5. Carefully wipe off the fan blades and motor with a soft

cloth. Do not bend the fan blades. If the fan blades are

excessively dirty, wash with warm, soapy water and

rinse thoroughly.

WATER-COOLED CONDENSER AND WATER

REGULATING VALVE

The water-cooled condenser and water regulating valve may

require cleaning due to scale build-up.

Low ice production, high water consumption and high

operating temperatures and pressures all may be symptoms

of restrictions in the condenser water circuit.

Because the cleaning procedures require special pumps and

cleaning solutions, they must be performed by qualified

maintenance or service personnel.

!Warning

The condenser fins are sharp. Use care when

cleaning them.

Part Number 80-0111-9 6/11 45

QM45/Q130/Q170/Q210/Q270

INTERIOR CLEANING AND SANITIZING

General

Clean and sanitize the ice machine every six months

for efficient operation. If the ice machine requires more

frequent cleaning and sanitizing, consult a qualified

service company to test the water quality and

recommend appropriate water treatment.

The ice machine must be taken apart for cleaning and

sanitizing.

Cleaning and Sanitizing Procedure

Ice machine cleaner is used to remove lime scale and

mineral deposits. Ice machine sanitizer disinfects and

removes algae and slime.

!Caution

Use only Manitowoc approved Ice Machine

Cleaner (part number 95-0546-3) and

Sanitizer (part number 94-0565-3). It is a

violation of Federal law to use these

solutions in a manner inconsistent with their

labeling. Read and understand all labels

printed on bottles before use.

!Caution

Do not mix Ice Machine Cleaner and

Sanitizer solutions together. It is a violation of

Federal law to use these solutions in a

manner inconsistent with their labeling.

!Warning

Wear rubber gloves and safety goggles

(and/or face shield) when handling Ice

Machine Cleaner or Sanitizer.
