Installation Guidelines for Chillers：
A Complete Safety and Performance Handbook from Transport to Commissioning
Why Is Proper Chiller Installation So Important？
As a core component in maintaining stable temperatures within industrial processes,
a chiller’s installation quality directly affects its performance, reliability, and lifespan.
Many equipment failures, performance issues,
and even potential safety hazards often stem from neglecting proper installation procedures.
Correct installation ensures the chiller can operate at its designed cooling capacity
while preventing premature wear caused by improper placement or incorrect operation.
Whether positioning a new unit or relocating an existing one,
all procedures must strictly follow the manufacturer’s manual, with personnel safety as the primary priority.
This guide covers every critical step and precaution
—from transportation to final commissioning—to help ensure your investment delivers maximum long-term value.
📦Professional Transportation Guidelines：Stability and Safety Above All📦
Transporting and handling a chiller before installation is the first—and most critical—line of defense for equipment protection.
Because chillers contain precision internal components,
any improper handling may cause hidden damage that compromises long-term stability.
Below are essential considerations during professional transport：
1️⃣ Accurately Confirm Machine Weight and Specifications ⚖️
Before hoisting or moving the unit, always confirm the chiller’s net weight and gross weight from the equipment manual or nameplate.
📌 Load Capacity Selection：Choose handling equipment—such as forklifts or cranes—and chains/slings with load capacity significantly higher than the chiller’s weight.
Overloading is strictly prohibited as it may cause chain/sling breakage, dropping the equipment, or serious safety incidents.
📌 Space Requirements：Ensure the transport container, elevator, or cargo lift has sufficient space to accommodate the unit safely.
2️⃣ Maintain Stability — No Tilted Handling 🚫
Chillers contain compressors, heat exchangers, and other precision components.
Tilting can cause internal displacement or oil circuit damage.
📌 Handling Principle：The unit must remain upright and be placed gently at all times.
The tilt angle must never exceed the manufacturer’s specified limit (typically 15°).
📌 Hoisting Principle：Always use manufacturer-designated lifting points or lift from the base structure.
Never lift the entire chiller from a single point or from external panels.
3️⃣ Safety Inspection and Securing of Lifting Slings 🔗
📌 Sling Selection：Choose chains, slings, or lifting straps rated appropriately for the unit’s weight.
📌 Safety Locks：Ensure all hooks and locking mechanisms are fully tightened, with no looseness or slippage.
This step is critical to prevent equipment free fall.
4️⃣ Unloading Procedures: Vertical Movement Only ⬇️
When unloading the chiller, use vertical up-and-down movements.
Strong shocks or impacts can irreversibly damage the refrigeration system—especially compressors and electronic control modules.
📍Environmental Considerations for Selecting an Ideal Installation Site📍
Choosing the right installation location is essential for ensuring stable long-term operation.
1️⃣ Ventilation and Heat Dissipation
Install the chiller in a well-ventilated indoor area.
Ensure that air inlets and outlets are unobstructed.
Maintain adequate clearance from walls and equipment (typically 1.5 m at the front and over 1 m at the sides)
to avoid hot-air recirculation that reduces cooling efficiency.
2️⃣ Load-Bearing Capacity
The floor or base must have sufficient structural strength to support the chiller’s full operating weight, including internal water or refrigerant.
3️⃣ Ambient Temperature
Avoid areas where ambient temperature exceeds 40°C.
If temperature is high, consider additional ventilation (e.g., industrial fans).
4️⃣ Low-Temperature Protection
In cold regions or during winter shutdown, take anti-freeze precautions such as draining the water circuit or adding antifreeze to prevent freezing damage.
5️⃣ Prohibited Environments
Do not install the chiller in wet, outdoor, rain-exposed areas, or in hazardous locations containing explosive gases or dust.
6️⃣ Vibration Control and Stability
For units without wheels, secure the chiller using the manufacturer’s recommended bolt holes and torque values.
For wheeled units, lock all casters after positioning to prevent movement during operation.
💧 Professional Requirements for System Piping Connections 💧
Beyond the equipment itself, the water circulation piping system is equally critical to cooling performance:
1️⃣ Proper Pipe Diameter：
Do not reduce pipe diameter arbitrarily, as this may cause pressure loss, insufficient flow, and reduced cooling capacity.
2️⃣ Leak-Free Sealing：
Apply thread seal tape to all threaded fittings to prevent air ingress or water leakage.
3️⃣ Water Quality Management：
Circulating water must be clean and free of dust or foreign particles to prevent clogging of the heat exchanger or pump.
4️⃣ Electrical Wiring：
All electrical work must be performed by licensed electricians.
Power must be disconnected before wiring, and grounding must follow electrical schematics to prevent electric shock.
🛡️ Safety Guidelines: Public Safety and Personnel Training Principles 🛡️
“Safety First” is the highest principle in all industrial equipment operations.
Equipment damage can be repaired, but injuries caused by negligence can result in irreversible consequences.
📜 Overview of Public Safety and Staff Training Requirements 📜
Companies must integrate public safety into daily operations, particularly in environments involving industrial machinery：
1️⃣ Professional Certification & Training：
All personnel involved in installation, operation, or maintenance must receive factory or accredited training and hold relevant certifications.
Unauthorized or untrained personnel must not approach or operate the equipment.
2️⃣ Workplace Environment Requirements：
📌 Clear Access Routes：Keep all pathways, equipment surroundings, and emergency exits unobstructed.
📌 Proper Lighting and Warnings：Maintain adequate illumination and install clear warning signs in hazardous areas (high temperature, high pressure, etc.).
📌Restricted Access：Clearly define work zones. Non-related personnel must be kept away to prevent accidental entry.
