Unit Installation Unit Installation Location Prior to the installation, select and verify the adaptability of the location for both indoor and outdoor units. Take into consideration all limitations and clearance requirements. The outdoor unit must comprise sufficient clearance for incoming air into the condenser, for discharge air, and for service access. - Page 9 Unit Installation Mounting of the Unit If the unit is to be installed on a roof surface or on a concrete base, observe the following guidelines: 1. The provided base pan rises the heating pump 2” above the installation base. 2.
- Page 10 Unit Installation IMPORTANT NOTE: These instructions are intended to provide a method of installation of the unit to the concrete base in order to establish a protective procedure in cases of strong winds. It is recommended to verify local codes for the application of methods and protocols for secure setting of the unit. Figure 4.

- Page 12 Unit Installation Precautionary Measures During Line Brazing All connections to indoor unit and to evaporator coil will be copper-to-copper. Brazing material should be done with the use of a copper-phosphorous alloy such as Silfos-5 or equivalent. DO NOT employ soft brazing alloy. Outdoor units contain service valves in both liquid and suction connections.
- Page 13 Unit Installation 4. Replace the Schraeder core once more onto the liquid and suction valves. 5. Carry out leak tests on all refrigerant line connections, including tapered valves at the service port to ensure they are all leak-free. DO NOT OVERTIGHTEN (between 40 and 60 in.lbs maximum).

Page 19: System Operation
System Operation System Operation Control Logic Description The variable speed system adopts the same 24VAC control as conventional heat pumps. Compressor speed is controlled according to coil pressures monitored by the pressure transducer. In order to ensure stable and appropriate capacity, compressor speed is modulated in accordance with evaporator pressure during the cooling mode, and in accordance with condensing pressure during the heating mode. - Page 20 System Operation Tf sensor is required for: – Protection against module temperature (high temperature) A pressure transducer (PT) is required for: – Operating speed control – Outdoor electronic expansion valve (heat pump only) – High pressure protection (heating mode heat pump only) –...
