<br /> <br /> <br />Version 10.22.2021 Page 4 of 9 VRV Maintenance Plan <br /> <br />Customer Benefits with Daikin VRV Preventive Maintenance Program <br /> <br /> Coil Cleaning & Filter Changing (optional) - As the outdoor or indoor heat exchangers <br />accumulate dust or pollen particulate, the VRV system compensates by increasing fan <br />speeds. The results are higher energy costs, and capacity reduction at full load. <br /> <br /> Confirm Proper Refrigerant Level - Any loss in refrigerant will affect the system’s capacity and <br />efficiency. A low refrigerant condition will force the VRV compressor to increase speed in an <br />attempt to circulate more refrigerant to the indoor units. This increases energy consumption <br />and causes premature wear on the VRV compressor. <br /> <br /> Daikin System Analyzing – Use of Daikin’s service checker / data logging equipment allows <br />HMS to evaluate system performance and make recommendations for improvement. <br /> <br /> DIII Network - Daikin’s DIII communication network transfers data between all equipment on <br />the network. As part of our Preventative Maintenance Service Agreement, Hoffman will check <br />the integrity of this communication buss which is critical to the efficient control of the entire <br />system. <br /> <br /> Many VRV systems include highly engineered and complex ancillary equipment such as <br />100% outside air units. Hoffman’s team of technicians is trained on equipment made by <br />multiple manufacturers and has the expertise required to provide maintenance on the overall <br />system. <br /> <br /> OEM Parts Stock - The Hoffman Organization is a major parts and equipment distributor for <br />Daikin. We have extensive inventory on hand in the event of a service emergency. <br /> <br /> Service Discounts - Our Service Agreement Customers benefit from a discount on parts, <br />equipment, and labor charges if a service call is needed. <br /> <br /> Priority Response - Premium response time is given to our service agreement customers as a <br />benefit to your preferred status. <br /> <br /> In addition to our standard preventative maintenance offering, customers may elect to pre- <br />purchase a block of hours to be used for non-preventative maintenance and/or repair <br />services. These hours can be used at the customer’s discretion and may be applied to <br />equipment not included in the PM agreement. <br /> <br /> Maintain Performance - Our Daikin Factory Authorized preventive maintenance program <br />provides evaluation of critical components and settings which may lead to recommendations <br />on how to optimize performance, efficiency, and extended the lifespan of your VRV system. <br /> <br /> Support facility staff and establish a schedule to provide seasonal inspections/maintenance. <br />Ideally, the mutually developed schedule will allow time to address deficiencies before peak <br />heating/cooling season and allow maximum facility uptime. <br /> <br /> <br /> <br />DocuSign Envelope ID: ACC31D61-4DF0-41A9-96AD-1C9FDD42E6A9
