13 R34a Flooded (97 to 506 tons) Installation requirements: Be sure to take the base preparation and structure into consideration seriously during installation,particularly on rooftop installations in order to avoid noise and vibration.consulting the building designer before conducting installation is recoended. drainage ditch should surround the base to ensure dewatering occurs. nti-vibration pad is to be placed between the base frame and foundation in order to avoid vibrations and unnecessary noise, and make sure the unit is aclinic during installation Typical Isolation structure nchor Bolt Chiller Frame Base Rubber Pad Steel Base Plate Concrete Base Notes: The maximum altitude difference (levelness) should be within 3 for the chiller base. The base should be raised 00. The installation base of the unit must be concrete or steel structure, which can bear the running weight of the machine. The top should be horizontal. It is ideal to prepare a drainage ditch around installation base. Put the steel plate and anti-vibration pad in the correct position. Finish the installation of the unit and the foundation bolt before secondary concreting. The foundation bolt should protrude 00. Spring isolators are specified on the sales order as an option.

16 R34a Flooded (97 to 506 tons) Typical piping system ll piping should be installed independently in order to convey any stress and vibration to the chiller and have sufficient space for maintenance. Water flow switch is required and should be installed on the straight line (5 times the pipe diameter) of the Chilled/Cooling water outlet. It is recoended to install a thermometer and pressure gauge to measure the units operational condition.

Choose the right pressure head for chilled water pump and cooling water pump. Choose proper pipe diameter and water velocity. Minimize pipe joint, reducing joints, pipe reducers, manifolds, and valves unnecessary to reduce local resistance loss. Choose proper water strainer (structure/meshes) and periodically clean. 2. Using a variable frequency water pump is recoended as it can reduce energy consumption by 30%-45%. 3. Using a water distributor and valves between floors or terminal SV to prevent chilled water from circulating in non-working terminals is recoended. 4. Do periodic cleaning of cooling tower and pipe system. 5. Select a location that provides sufficient air-flow for both air-inlet and outlet. 6. Make appropriate adjustments to chilled water inlet/outlet temperature and temperature difference according to the local climate. 5
