2.5 Make-up WATER SUPPLY CONNECTION (Optional - in non-freeze
Climate applications only)
A. The automatic water make-up system continually monitors the
reservoir tank and fills it when needed. Connect as follows:
1. Using appropriately rated hose or fluid piping connect the
“water make-up” connection to the plant’s water source.
2. Minimum make-up water supply pressure is normally 20 psi.
3. Install an owner supplied shut off valve in the make-up water supply line. Install
this valve on the outside of the unit.
4. Use a back flow prevention device as may be required by local codes to prevent
possible contamination of potable water.
B. Do not use automatic water make-up system when operating with glycol below 48°F or
when ambient temperature may be 35°F or lower.
2.6 ELECTRICAL CONNECTION
A. STANDARD MODELS
1. Units are constructed with a weather resistant electrical enclosure and branch
circuit fusing. Electrical power supply requirements are identified on the
equipment data plate. Determine the plant’s voltage supply is the same as the
unit’s voltage requirements.
2. All electrical wiring must comply with local codes and the National Electric Code.
3. Electrical power supply requirements for standard units are identified on the
equipment data tag. Determine that the plant’s voltage supply is the same as the
unit’s voltage requirements, taking into account the SSCR Rating.
WARNING: Check local codes to determine proper use of back flow prevention device in water
make-up supply line.
WARNING: Do not connect the unit to a voltage supply not equal to the unit’s voltage
requirements as specified on the unit’s data plate. Use of incorrect voltage will void the unit’s
warranty and cause a significant hazard that may result in serious personal injury and unit
damage.
WARNING: Electric Shock Hazard. High Voltage is present in the electrical cabinet. Disconnect
power before servicing. Follow all facility lock-out tag-out procedures.
