INTRODUCTIONThis installation manual concerns outdoor units of the DaikinCMSQ-A7 series. These units are designed for outdoor installationand used for heat pump applications.The CMSQ-A7 units can be combined with Daikin indoor units for airconditioning purposes, and suitable for R410A.The present installation manual describes the procedures forunpacking, installing and connecting the CMSQ-A7 units. Installationof the indoor units is not described in this manual. Always refer to theinstallation manual supplied with these units for their installation.1.1. CombinationThe indoor units can be installed in the following range.■ Always use appropriate indoor units compatible with R410A.To learn which models of indoor units are compatible withR410A, refer to the product catalogs.■ Total capacity/quantity of indoor unitsCMSQ200A7W1BCMSQ250A7W1B Air conditioning system Installation manualREAD THIS MANUAL ATTENTIVELY BEFORE STARTINGUP THE UNIT. DO NOT THROW IT AWAY. KEEP IT IN YOURFILES FOR FUTURE REFERENCE.IMPROPER INSTALLATION OR ATTACHMENT OFEQUIPMENT OR ACCESSORIES COULD RESULT INELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OROTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLYTO USE ACCESSORIES MADE BY DAIKIN WHICH ARESPECIFICALLY DESIGNED FOR USE WITH THEEQUIPMENT AND HAVE THEM INSTALLED BY APROFESSIONAL.DAIKIN EQUIPMENT IS DESIGNED FOR COMFORTAPPLICATIONS. FOR USE IN OTHER APPLICATIONS,PLEASE CONTACT YOUR LOCAL DAIKIN DEALER.IF UNSURE OF INSTALLATION PROCEDURES OR USE,ALWAYS CONTACT YOUR DEALER FOR ADVICE ANDINFORMATION.THIS AIR CONDITIONER COMES UNDER THE TERM"APPLIANCES NOT ACCESSIBLE TO THE GENERALPUBLIC".The refrigerant R410A requires strict cautions for keepingthe system clean, dry and tight.■ Clean and dryForeign materials (including mineral oils such asSUNISO oil or moisture) should be prevented fromgetting mixed into the system.■ TightR410A does not contain any chlorine, does notdestroy the ozone layer, and does not reduce theearth's protection against harmful ultraviolet radiation.R410A can contribute slightly to the greenhouseeffect if it is released. Therefore we should takespecial attention to check the tightness of theinstallation.Read "6. Refrigerant piping" on page 4 carefully and followthese procedures correctly.Since design pressure is 4.0 MPa or 40 bar (for R407Cunits: 3.3 MPa or 33 bar), pipes of larger wall thicknessmay be required. The wall thickness of piping must becarefully selected, refer to paragraph "6.2. Selection ofpiping material" on page 4 for more details.Total capacityof indoor unitsTotal quantityof indoor unitsCMSQ200 100~200 2~4CMSQ250 125~250 2~4NOTE The table above shows the possible total capacityand number of possible indoor units whenconfigured in a standard combination.Refer to the service manual for more details whenusing a configuration other than a standardcombination.
