RECEIVING YOUR CHILLER

INSPECTION CHECKLIST

When the unit is delivered, verify that it is the correct unit and that it is properly equipped.

Compare the information which appears on the unit nameplate with the ordering and submittal information.

Inspect all exterior components for visible damage. Report any apparent damage or material shortage to the carrier

and make a "unit damage" notation on the carrier's delivery receipt. Specify the extent and type of damage found

and notify the G&D Sales Office at 800-555-0973.

Do not proceed with installation of a damaged unit without sales office approval.

To protect against loss due to damage incurred in transit, complete the following checklist upon receipt of the unit.

•Inspect the individual pieces of the shipment before accepting the unit. Check for obvious damage to the unit

or packing material.

•Inspect the unit for concealed damage as soon as possible after delivery and before it is stored. Concealed

damage must be reported within 5 days.

•If concealed damage is discovered, stop unpacking the shipment. Do not remove damaged material from the

receiving location. Take photos of the damage, if possible. The owner must provide reasonable evidence that

the damage did not occur after delivery.

•Notify the carrier's terminal of the damage immediately, by phone and by mail. Request an immediate, joint

inspection of the damage with the carrier and the consignee.

•Notify the G&D sales representative and arrange for repair. Do not repair the unit, however, until damage is

inspected by the carrier's representative.

INSTALLATION GUIDE •USER MANUAL VERTICAL AIR SERIES

G&D CHILLERS, INC. • GD-VA-R2022C

INSTALLATION OVERVIEW

LOCATION

Air cooled units must sit outside and be

anchored to a solid level surface. A

concrete pad is recommended. Location

should be free of grass and other debris

that could plug condenser fins.

Ensure minimum clearance* between

condenser intake side and any buildings,

walls, etc.

No walls or obstructions in front of the

unit: Louvered access side must be open

to free air. No roofs or overhangs above

chiller condenser.

Liquid cooled chillers may be installed on

a concrete pad outdoors. A properly sized

pump and liquid cooling system for the

chiller condenser must be supplied by the

end user. Contact G&D Chillers for

additional information and assistance with

sizing.

ELECTRICAL

1. Supply unit with the proper voltage and protect against power spikes.

Use only copper wire. Size wire and according to any/all applicable

local and national codes. Refer to chart to the right for proper torque

values. Refer to spec sticker on control panel for all electrical ratings.

2. Field-installed service disconnect required

3. Unit must be properly grounded at the provided grounding lug.

If multiple ground wires are used, all wires must be twisted together

prior to tightening ground lug.

4. Use only hubs or fittings that maintain the same environmental ratings

as the enclosure.

5. When turning unit off for an extended length of time, leave power

energized. (This will leave the crankcase heater on and keep the

crankcase warm for the next start up.

INSTALLER-SUPPLIED COMPONENTS

Customer wiring interface connections are shown in the electrical schematics and connection diagrams that are

shipped with the unit. The installer must provide the following components if not ordered with the unit:

•Power supply wiring (in conduit) for all field-wired connections.

•All control (interconnecting) wiring (in conduit) for field supplied devices.

•Unit disconnect (fused).

CHILLER INSTALLATION - MECHANICAL

LOCATION REQUIREMENTS SOUND CONSIDERATIONS

•Refer to G&D data sheet for sound data

•Locate the unit away from sound-sensitive areas

•Chilled fluid piping should not be supported by chiller frame

•Seal all wall penetrations

Note: Consult an acoustical engineer for critical applications.

FOUNDATION

Provide a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e.,

including completed piping, and full operating charges of refrigerant, oil and water). G&D Data sheet for unit

operating weights. Once in place, the unit must be level within 1/4" (6.4 mm) over its length and width as well as

anchored to the surface. Construct a concrete pad fully supporting the footprint of the chiller. Mount the unit directly

to the concrete pads. Level the unit using the base rail as a reference. The unit must be level within 1/4" over the

entire length. Chiller must be in contact with the concrete pad around its complete perimeter. G&D Chillers is not

responsible for equipment problems resulting from an improperly designed or constructed foundation.

IINSTALLATION GUIDE •USER MANUAL VERTICAL AIR SERIES

G&D CHILLERS, INC. • GD-VA-R2022C

CLEARANCES

Provide enough space around the unit to allow the installation and maintenance personnel unrestricted access to

all service points. Observe all applicable local and national codes. Refer to submittal drawings for the unit

dimensions, to provide sufficient clearance for the opening of control panel doors and unit service. All sides should

have clearance not less one full width of the condenser to any obstruction. Combined void on all four sides shall not

be less than 75%, and all obstructions should meet the minimum clearance distance listed above.

PROCESS PIPING

Cooling fluid connections are flanged.

Thoroughly flush all fluid piping to the chiller before making the final piping connections to the unit.

CAUTION: PROPER WATER TREATMENT!

The use of untreated or improperly treated water in a Chiller may result in scaling, erosion, corrosion, algae or slime.

It is recommended that the services of a qualified water treatment specialist be engaged to determine what water

treatment, if any, is required. G&D assumes no responsibility for equipment failures which result from untreated or

improperly treated water, or saline or brackish water.

VALVES AND VENTING

A vent is provided on the top of the reservoir. Be sure to provide additional vents at high points in the piping to bleed

air from the chilled fluid system. Do not pressurize reservoir. Install necessary pressure gauges to monitor the

entering and leaving chilled water pressures. Provide shutoff valves in lines to the gauges to isolate them from the

system when they are not in use. Use rubber vibration eliminators to prevent vibration transmission through the

water lines. All piping must be adequately secured and supported. If desired, install thermometers in the lines to

monitor entering and leaving fluid temperatures. Install shutoff valves on both the entering and leaving water lines

so that the chiller can be isolated for service.

CHILLER PIPING COMPONENTS

Piping components include all devices and controls used to provide proper cooling system operation and unit

operating safety.

•Air vents (to bleed air from system)

•Water pressure gauges with shutoff valves

•Vibration eliminators

•Shutoff (isolation) valves

•Thermometers (if desired)

•Fluid Strainer

The fluid strainer is field supplied, field installed and shall provide taps for the pressure gauges on the inlet and

outlet. The wye-strainer shall be installed on the return line and must be one pipe size larger than the main line

piping.

Install pressure gauges in order to measure differential pressure across the strainer. This will help to determine when

it is necessary to clean the water strainer.
