  • Page 24: Introduction

    The Multiaqua Chiller System is not only unique in its application flexibility; it is unique in superior quality, rated capacities and rugged durability. When installed in accordance with these instructions the system will deliver years of trouble free service.

  • Page 25: System Description & Sequence Of Operation

    America) Manual “J”, Refer to the appendix A-2, Multi-Zone Systems. ACCA’s Internet address is http://www.acca.org/ Because of diversity a Multiaqua Chiller can serve more total air handler tonnage than chiller capacity. A 10-ton chiller may be delivering chilled liquid solution to 15 or more tons of air handler capacity. Because of cooling load diversity, the building does not need equal amounts of cooling in each area at the same time.

  • Page 26: Electrical & Physical Data

    ELECTRICAL AND PHYSICAL DATA The information contained in this manual has been prepared to assist in the proper installation, operation and maintenance of the chiller. Improper installation, or installation not made in accordance with these instructions can result in unsatisfactory operation and/or dangerous conditions and can cause the related warranty not to apply.
  • Page 27 Consult local building codes or ordinances for special installation requirements. When selecting a site to locate the chiller, consider the following: • A minimum clearance of 60” on the service access front, 12” on the rear air inlet and a 60” fan discharge clearance.

  • Page 28: Description Of Electrical Controls

    Description of Electrical Controls Control Transformer: The control transformer is rated at 24 vac, 40 va (1.6 amps @ 24vac) The pump bypass timer is a 24 vac, 3-wire control. Pump Bypass Timer: When energized the timer will bypass the flow switch for 10 seconds (by creating a circuit to the pump relay), energizing the pump relay, allowing the pump to operate long enough to close the flow switch.
  • Page 29 Description of Electrical Controls (continued) The low-pressure switch is an automatic reset control Low Pressure Switch: that senses compressor suction line pressure. It opens at 40 PSIG and closes at 80 PSIG. Flow Switch: The flow switch senses liquid solution flow. The paddle of the switch is inserted through a fitting into the pump discharge line.

  • Page 30: Chiller Controls Sequence Of Operation

    Chiller Controls Sequence of Operation When powered up, the Multiaqua chiller system energizes the control transformer creating 24 vac control voltage. First the pump bypass timer is energized and temporarily bypasses the flow switch, energizing the pump relay. The pump then starts to move liquid solution through the piping system (in a properly filled and air purged system). The movement of liquid solution from the pump discharge keeps the flow switch closed.

    10 °F below condensing temperature. Description Of Refrigerant Components Scroll Compressor: All Multiaqua chillers feature Scroll compressors. Scroll technology ensures reliable high performance at a low sound level over a wide range of operating conditions.
  • Page 32 The counter flow design and fluid turbulence ensures maximum heat exchange at minimal pressure drop. Thermal Expansion Valve: Multiaqua chillers are equipped with Thermal Expansion valves. The valves feature a liquid charged sensing bulb for consistent superheat at various load conditions.

  • Page 33: Piping System Components

    Piping System Components Supply Storage Tank: The supply storage tank must be used in the system with less than 25 gallons of liquid solution. The tank prevents rapid cycling of the compressors and acts as a reserve for chilled liquid solution. Supply storage tank must be insulated in the field.

    Piping resistance or pressure drop is measured in feet of head. A foot of head is the amount of pressure drop imposed in lifting liquid solution one foot. Pumps in the Multiaqua system are designed to move rated liquid solution flow (see...

  • Page 35: Banked Chiller Configuration

    Banked Chiller Configuration Notes: Installing Multiaqua chillers in parallel is recommended.

  • Page 36: Installation Notes

    Installation Notes: Piping such as PEX,steel, copper or PVC can be used with the Multiaqua system. Check local building codes for material conformation. Care must be taken when using PVC as the presence of propylene glycol may destroy plastics. Pressure drop data for the selected piping material is readily available and should be used. Should the Multiaqua chiller be installed using existing steel (ferrous metal) piping system, dielectric fittings must be used at the chiller and air handler.

  • Page 37: Propylene Glycol Content

    Liquid solution expansion and contraction within the closed system must be compensated for with an expansion tank. The expansion tank used with the Multiaqua system, is a steel tank with a rubber bladder attached to it internally. There is air pressure on one side of the rubber bladder that keeps the bladder pushed against the sides of the tank before the system is filled with liquid solution (illustration above).

  • Page 38: Filling The System With Propylene Glycol

    Filling System with Liquid Solution and Coolant (Propylene Glycol) Before filling system with Propylene Glycol and water, pressure test the piping system with compressed air. Testing should be done at a maximum of 50 psi.The system should hold air pressure for a minimum of one hour with no leakage.
