This hose is typically stainless steel braid and includes a swivel fitting on one end for easy removal and is flexible to help isolate the unit for quieter operation. Isolation valves for servicing, y-strainers for filtering and memory-stop flow valve or a balancing valve can be provided for consistent water flow through the unit.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Installation Notes cont. Installing Horizontal Units channel as shown in the Horizontal Dimensional Data. The unit should be pitched approximately 1/4 in. toward the drain in both directions to facilitate the removal of condensate. Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket prior to setting the unit in place. Horizontal units are available with side or end discharge.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Installation Notes cont. Ductwork • Ensure return air grilles will not allow line of site noise to transfer to adjacent space. Use a sound barrier or some other material to isolate the grille from the unit. A supply grille, boot and short piece of flex duct pointed away from the unit can greatly attenuate equipment noise. • Use a canvas isolation duct connector at the supply and return duct connection of the unit.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Duct System An air outlet collar is provided on vertical top flow units and all horizontal units to facilitate a duct connection. A flexible connector is recommended for discharge and return air duct connections on metal duct systems. Uninsulated duct should be insulated with a minimum of 1-inch duct insulation.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Condensate Drain On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a 3/4 in. PVC female adapter and a flexible connecting hose. The female adapter may exit either the front or the side of the cabinet. The adapter should be glued to the field-installed PVC condensate piping.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Water Quality with extremely hard water, the owner should be informed that the heat exchanger may require occasional flushing. Failure to adhere to the guidelines in the water quality table could result in loss of warranty. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL System Cleaning and Flushing Refill the system with clean water. Test the system water for acidity and treat as required to leave the water slightly alkaline (pH 7.5 to 8.5). The specified percentage of antifreeze may also be added at this time. Use commercial grade antifreeze designed for HVAC systems only. Environol™ brand antifreeze is recommended.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Open Loop Ground Water Systems Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure.
VERSATEC 500 7-30 TON INSTALLATION MANUAL - Formerly Versatec XL Electrical Connections General 208 Volt Operation Be sure the available power is the same voltage and phase as that shown on the unit serial plate. Line and low voltage wiring must be done in accordance with local codes or the National Electric Code, whichever is applicable. All 208/230 volt units are factory wired for 230 volt operation. For 208 volt operation, the red and blue transformer wires must be switched on terminal strip PS.

An open loop system should be checked to ensure that the well head is not allowing air to infiltrate the water line. Lines should always be airtight. 2. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the discharge line to prevent loss of pressure during off cycles.
