How Can We Help You?

We recommend quarterly preventative maintenance for most cooling systems. This includes filter changes, coil cleaning, and system inspections. For high-demand environments like data centers, monthly inspections may be necessary. Refer to your specific product manual for detailed maintenance schedules or contact our support team for a customized maintenance plan.

Product registration can be completed online through your customer account portal. You'll need your product serial number and proof of purchase. Registration must be completed within 30 days of installation to activate the full warranty coverage. For assistance with registration, contact our customer service team at support@cooltech.com.

Optimal settings vary by industry and application. For data centers, ASHRAE recommends 18-27°C (64-81°F) and 40-60% relative humidity. Healthcare facilities typically require 20-24°C (68-75°F) with 30-60% humidity. Manufacturing environments may have specific requirements based on processes. Our technical documentation provides detailed guidelines for your specific industry and equipment configuration.

Unusual noises may indicate loose components, bearing wear, or airflow obstructions. First, check for any debris in fans or vents. Verify that all access panels are secure. For grinding or squealing sounds, bearings may need lubrication or replacement. Rattling often indicates loose mounting hardware. If the noise persists after these checks, please contact technical support for assistance.

Error code E-104 indicates a refrigerant pressure issue, typically low pressure in the system. This could be caused by a refrigerant leak, blocked filter, or faulty pressure sensor. First, check for any visible refrigerant leaks and ensure all access panels are properly sealed. If you have the necessary certifications, verify refrigerant levels. Otherwise, this issue requires a certified technician. Please contact our service department to schedule a repair.

Reduced cooling capacity can result from several factors. Check for dirty air filters and coils, which restrict airflow. Verify that all fans are operating correctly and air vents are unobstructed. For chilled water systems, check water flow and temperature. Ensure the system isn't undersized for current heat loads, especially if equipment has been added to the space. Our diagnostic guide in the knowledge base provides a comprehensive troubleshooting flowchart.

Minimum clearance requirements vary by model, but generally, we recommend at least 36 inches (91 cm) of service clearance in front of equipment, 24 inches (61 cm) on sides with access panels, and 12 inches (30 cm) for rear exhaust. Overhead clearance should be at least 24 inches (61 cm) for proper airflow. Always refer to your specific model's installation manual for exact requirements, as some high-capacity units may need additional space.

Most cooling systems require installation by certified technicians to maintain warranty coverage. Installation involves electrical connections, refrigerant handling, and precise setup procedures that require professional training and tools. Additionally, many jurisdictions require permits and licensed professionals for HVAC installations. Our CoolTech Certified Installer network can provide qualified technicians in your area who are factory-trained on our equipment.

Our cooling systems support standard BMS protocols including BACnet, Modbus, and LonWorks. For integration, locate the communication ports on the main control board (typically labeled BMS or COMM). Configure the protocol settings through the system's interface menu under "External Communications." Connection requires a shielded twisted pair cable and proper addressing configuration. For detailed integration instructions, refer to the BMS Integration Guide in our technical documentation library.
