Installation General IMPORTANT: Mammoth water source heat pumps should be installed only by qualified personnel, experienced in the installation of this equipment and related systems. Read these instructions carefully before unpacking, installing and operating this unit 1. To prevent damage, this equipment should not be operated for supplementary heating and cooling during the construction period. 2.
Unit Location and Clearances Units can be mounted on the floor or a concrete pad, typically in a mechanical closet or other area enclosed from the space to promote a quieter occupied environment. The diagrams below show minimum suggested clearances. Any additional clearances would be beneficial, but not always necessary. The requirements on any specific unit may increase or be reduced depending on several factors such as maintenance requirements and mechanical or electrical installation codes.
Ductwork and Attenuation Discharge ductwork is normally used with B-vintage single circuit units. Return air ductwork may also be required. Discharge ductwork should include a non-insulated transition from the unit connection to a flexible connector at the full duct size, a short run of duct and an elbow internally lined with insulation but without turning vanes. The main duct tees into branch circuits with discharge diffusers.
Supply Piping IMPORTANT: Prior to first operation of B-Vintage units, the water circulation system must be cleaned and flushed of all construction dirt and debris. After the cleaning and flushing has taken place, the initial connection should have all valves wide open in preparation for start-up. 1. All units should be connected to supply and return piping in a two-pipe reverse return configuration.
Cleaning and Flushing IMPORTANT: Prior to first operation of B-vintage units, the water circulation system must be cleaned and flushed of all construction dirt and debris. After the cleaning and flushing has taken place, the initial connection should have all valves wide open in preparation for the water system flushing. 1. If the B-Vintage units are equipped with water shutoff valves, either electric or pressure operated, the supply and return run-outs must be connected at each heat pump location.
FANWALL TECHNOLOGY® Assembly Fan / Cone Alignment Figure 1—FANWALL® cone alignment 1. Temporarily attach the cone to the cell inlet using the screws and washers provided, or slightly loosen the screws holding the cone if already installed. Use a minimum of four screws for this step. a. Refer to the fan wheel overlap drawings provided to determine where to set the wheel with respect to the cone. b.
Start-up 1. Open all valves to full open position and turn on power to the heat pump. 2. Set room temperature sensor for “Fan Only” operation by selecting “Off” at the system switch and “On” at the fan switch. If “Auto” fan operation is selected, the fan will cycle with the compressor. Check for proper air delivery. 3. Units have time delays which help protect the compressor(s) against short cycling. In the cooling mode, after 30 seconds of operation, check the discharge grilles for cool air delivery.
Operating Limits Environment This equipment is designed for indoor installation only. Sheltered locations such as attics, garages, etc., generally will not provide sufficient protection against ex- tremes in temperature and/or humidity, and equipment performance, reliability, and service life may be adversely affected.
I/O 583 Mammoth I/O Zone 583 controller delivers powerful control and communications features all in a compact, economical package. Fully capable of operating in a 100% stand-alone control mode, the I/O Zone 583 can connect to a Building Automation System (BAS) using any of today’s most popular protocols, such as BACnet, Modbus, N2, and LonTalk,. The I/O Zone 583 also supports communication to Mammoth line of intelligent space sensors and keypad/display units.

I/O Flex 6126 The standard factory-integrated DDC controller provides control flexibility that can be easily customized to meet any sequence of operation needs. It is fully capable of operating in a 100% stand-alone mode or can connect to a Building Automation System (BAS) using any of today’s four leading protocols: BACnet, Modbus, N2, and Lontalk. The base controller provides ample input/output capacity, plus support for an expander board if additional I/O capacity is required.

MAMMOTH DDC CONTROLS Keypad Locally access controllers and operational properties with the easy-to-use BACview6 keypad/display. It plugs into an Rnet connection on a 6126 controller and allows you to display and modify properties. The BACview6 features a numeric keypad, directional keys, and four programmable function keys. A large 4-line by 40character backlit LCD display is provided for easy reading even in poor lighting conditions. The device also includes an alarm indicator light.
General Maintenance Normal maintenance on B-Vintage units is generally limited to filter changes. Air filter changes are required at regular intervals. The time period between changes will depend upon the project requirements. It is suggested that the filter be checked at 60-day intervals for the first year until experience is acquired. Periodic lockouts almost always are caused by air or water problems. The lockout (shutdown) of the heat pump is a normal protective result.
Troubleshooting R-410A Charging Due to the zeotropic nature of R-410A, it should be charged as a liquid. In situations where vapor is normally charged into a system, a valve should be installed in the charging line to flash the liquid to vapor while charging. The In’s and Out’s of R-410A R-410A is a non-ozone depleting blend of two Refrigerants — HFC-125 and HFC-32 in a fifty percent mixture. Refrigerant 410A exhibits higher operating pressure and refrigeration capacity than R-22.
