1.2 SYSTEM REQUIREMENTS: possible icing from defrost condensate. Aermec heat pump system are derived from actual laboratory testing of the equipment. It is recommended that all deisgn criteria Avoid placing the heat pump near areas such as sleeping be met or exceeded to ensure proper operation and quarters or study rooms. Normal operating sound levels may efficient performance. be objectionable if the heat pump is placed near certain The designed system criteria are listed in the heat pump rooms. A shift in sound type does occur during the defrost unit specification sheets and in the heat pump technical man‐ mode. The defrost mode generally lasts no longer than 5 ual minutes This heat pump has been factory charged with a quantity of refrigerant (R410A) 1.4 MINIMUM WATER VOLUME IMPORTANT: Refer to “Aermec System Water Volume Guide” (you can download it on aermec.us in tutorial books section) ANK heat pumps need a minimum volume of 35 gallons of water/glycol. If the version is an HA it has an internal 25 gallon tank so the system must contain a minimum of 10 additional gallons when all zones but the smallest are closed or not operating. (Only count the smallest zone volume along with the pipes to the manifold. If the heat pump does not have an internal buffer tank you must add 35 gallons in the system with a buffer tank or piping. 1.5 MINIMUM CLEARENCE 2 ... -

1.6 ELECTRICAL REQUIREMENTS IMPORTANT: Electrical wiring, disconnect means and over current protection are to be supplied by the installer. Refer to the rating plate for the maximum over current protection, minimum circuit ampacity, and operating voltage. See wiring diagram. Install an adequately sized branch circuit disconnect, per the NEC, within sight of and readily accessible from heat pump. The cable or conduit and fittings connected from the disconnect to the heat pump shall be rated for outdoor use. Check the heat pump rating plate and follow the appropriate instructions below. NOTE: All wiring must be suitable for outdoor use. Use copper conductors only. All field wiring must be done in accordance with National Electrical Code requirements, applicable requirements of UL, or local codes, where applicable. Electrical wiring, disconnect means and over current protection are to be supplied by the installer.

2 INSTALLATION INSTRUCTIONS This heat pump is shipped in one package, completely assembled and wired. The indoor controller is shipped in a separate ANK 030‐045‐050 H‐HP carton when ordered. 1. Check the heat pump rating plate to confirm specifications are as ordered. 2. Upon receipt of equipment, carefully inspect it for possible shipping damage. Take special care to examine the unit Air vent inside the carton if the carton is damaged. If damage is found, it should be noted on the carrier’s freight bill. Damage claims should be filed with the carrier immediately. Claims of shortages should be filed with the seller within 5 days. NOTE: If any damages are discovered and reported to the carrier, do not install the unit because your claim may be denied. 2.1 HYDRONIC CONNECTIONS Water / glycol piping must be connected by a licensed, or certified technician using established procedures. IMPORTANT: ANK 030‐045‐050 HA Connecting water lines must be clean, properly sized (minimum 1 ¼ inch). Reducing fitting shall not be used Air vent Use care with the water / glycol lines during the installation process. If pex is used it can be cut by sharp objects. Do not remove the caps from the lines or system connection points until connections are ready to be completed. 1. Route the supply and return lines from the fittings on the indoor manifold or tank to the fittings on the heat pump. Run the lines in as direct a path as possible avoiding unnecessary turns and bends. Air vent ... -
