If multiple heat pumps are on-site, confirm that the multiple heat pump configuration has been utilized. This will prevent multiple heat pumps attempting to start at the same time, causing an excessive power drop at start-up. Multiple heat pumps installed at the same site may benefit from automatic sequencing controllers (ASC) to avoid excessive power draws at start-up.
1 - Installation Failure to heed the following will result in injury or death. DANGER Deactivate power while routing wiring to control board. Heat Pump equipment must be installed within manufacturer specifications and must follow all National and/or State and Local installation guidelines. Follow all National Electric Codes (NEC) and/or State and Local guidelines.
The shipping brackets used to secure the heat pump to the pallet are approved mounting (hurricane) brackets. They should be used to anchor the heat pump to the pad. If needed, contact AquaCal ® to obtain anchoring kit information. Please have the heat pump model number and serial number when requesting support.
1.2.A Electrical Requirements Grounding and Bonding Follow local code requirements for proper grounding and bonding of heat pump equipment. A bonding lug has been provided on the lower left hand corner of the plumbing access panel. Surge Suppression The use of approved commercial surge protectors is strongly recommended. Sizing the Electrical Service Refer to equipment data plate for specific information required to size electrical service and over-current protection of the heat pump.
Minimum and Maximum Operating Voltage The heat pump must operate within specified voltages. Failure to heed the following may result in damage to equipment. NOTICE Operating equipment under higher or lower voltage conditions may result in damage to your compressor, motors or other electrical components.
Water Source WS03, WS05 SunPower SP05 Water Source WS10 1.2.C Access Panels Failure to heed the following will result in injury or death. DANGER Deactivate power while routing wiring to control board. Heat Pump equipment must be installed within manufacturer specifications and must follow all National and/or State and Local installation guidelines.
Water Source WS03, WS05 SunPower SP05 Water Source WS10 1.2.D Verifying Transformer Setting (Select Units) Transformer voltage must be confirmed and set correctly depending on the measured voltage found on the site. Incorrect settings may cause heat pump damage. The following procedure will allow the installer to set the heat pump's transformer for the appropriate site voltage.
1. Turn heat pump on by adjusting the thermostat to call for heating or cooling. If more than one heat pump is on- site, turn them all on. Allow time for all heat pump compressors to activate. 2. Measure the running site voltage. 3.
