  1. Cooling system is filled to proper level when shipped, with a mixture of 50% ethylene glycol and 50% distilled water. Clear tube between thermostat housing and reservoir should be filled with green coolant mixture. If level has dropped, check for evidence of leaks at all connections before adding fluid as described below. If coolant is at the correct level, skip to sea water connection in Connecting Seawater to Heat Exchanger section.<\/li>\n<\/ol>\n<\/div>\n\n\n\n

    1. Mix 50% ethylene glycol with 50% distilled water in a clean container.  Refer to Table 1 or glycol manufacturer\u2019s literature for freezing points.<\/li>\n<\/ol>\n\n\n

      1. Remove pressure cap on top of reservoir. Pour mixture in until level reaches top of clear tube between thermostatic valve and reservoir as shown in Figure 43.\u00a0 Filling reservoir above this level will not cause any damage but coolant may be expelled from pressure relief port below cap due to normal thermal expansion of coolant.<\/li>\n\n\n\n
      2. Connect 24 V to controller.

        1. At the MFD app or 5″ Touch Display check for any ALARMS<\/li>\n\n\n\n
        2. Press the POWER ON\/OFF button \"\" .<\/li>\n\n\n\n
        3. The flywheel will start to spin, and the glycol pump will start.<\/li>\n\n\n\n
        4. Recheck glycol level with fluid circulating in coolant circuit. Look down inside reservoir and check that coolant level is above upper port on reservoir as shown in Figure 43.\u00a0 Replace cap.<\/li>\n\n\n\n
        5. After several minutes of running, press POWER ON\/OFF button \"\" to turn power off to the flywheel and glycol pump. The glycol pump will stop, and the flywheel will coast to a stop.<\/li>\n\n\n\n
        6. Seawater cooling is not required when the Seakeeper<\/span><\/span><\/span><\/span> is powered off and the flywheel is coasting to a stop.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
        7. The cooling system is self-purging.\u00a0 If small amounts of air are in the system, they will most likely be dislodged during the first sea trial.\u00a0 Recheck level after sea trial and add fluid if required.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":9,"featured_media":0,"parent":20878,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"manual":[369],"model":[],"document_type":[],"hidden":[],"class_list":["post-20886","page","type-page","status-publish","hentry","manual-seakeeper-18-installation-manual-90672-3-s-n-18-254-2135-to-current"],"acf":[],"_links":{"self":[{"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/pages\/20886","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/comments?post=20886"}],"version-history":[{"count":2,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/pages\/20886\/revisions"}],"predecessor-version":[{"id":20946,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/pages\/20886\/revisions\/20946"}],"up":[{"embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/pages\/20878"}],"wp:attachment":[{"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/media?parent=20886"}],"wp:term":[{"taxonomy":"manual","embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/manual?post=20886"},{"taxonomy":"model","embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/model?post=20886"},{"taxonomy":"document_type","embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/document_type?post=20886"},{"taxonomy":"hidden","embeddable":true,"href":"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-json\/wp\/v2\/hidden?post=20886"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
