<br /> <br />Version 08262019 Page 4 of 9 <br /> <br />Customer Benefits with Daikin VRV Preventive Maintenance Program <br /> <br />x Coil Cleaning & Filter Changing (optional) - As the outdoor or indoor heat exchangers accumulate <br />dust or pollen particulate, the VRV system compensates by increasing fan speeds. The results are <br />higher energy costs, and capacity reduction at full load. <br /> <br />x 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 and <br />causes premature wear on the VRV compressor. <br /> <br />x Daikin System Analyzing – Use of Daikin’s service checker / data logging equipment allows HMS to <br />evaluate system performance and make recommendations for improvement. <br /> <br />x DIII Network - Daikin’s DIII communication network transfers data between all equipment on the <br />network. As part of our Preventative Maintenance Service Agreement, Hoffman will check the <br />integrity of this communication buss which is critical to the efficient control of the entire system. <br /> <br />x Many VRV systems include highly engineered and complex ancillary equipment such as 100% <br />outside air units. Hoffman’s team of technicians is trained on equipment made by multiple <br />manufacturers and has the expertise required to provide maintenance on the overall system. <br /> <br />x OEM Parts Stock - The Hoffman Organization is a major parts and equipment distributor for Daikin. <br />We have extensive inventory on hand in the event of a service emergency. <br /> <br />x Service Discounts - Our Service Agreement Customers benefit from a discount on parts, equipment, <br />and labor charges if a service call is needed. <br /> <br />x Priority Response - Premium response time is given to our service agreement customers as a <br />benefit to your preferred status. <br /> <br />x 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 services. <br />These hours can be used at the customer’s discretion and may be applied to equipment not <br />included in the PM agreement. <br /> <br />x Maintain Performance - Our Daikin Factory Authorized preventive maintenance program provides <br />evaluation of critical components and settings which may lead to recommendations on how to <br />optimize performance, efficiency, and extended the lifespan of your VRV system. <br /> <br />x Support facility staff and establish a schedule to provide seasonal inspections/maintenance. Ideally, <br />the mutually developed schedule will allow time to address deficiencies before peak heating/cooling <br />season and allow maximum facility uptime. <br />DocuSign Envelope ID: 4EBCEE15-C560-4E89-8C87-EA0F43F3CA6D
