ADD-ON GVDM-26 PUMP MODULE KIT
NOTE: This section applies only if a GVDM-26 Pump
Module is added. Refer to GVDM-26 instructions for
complete installation details.
GENERAL
This high efficiency water source heat pump series was
designed with a refrigerant to water heat exchanger
commonly know as a desuperheater coil factory-installed
for ease in installing optional GVDM-26 pump module kit.
The addition of this optional kit allows for heat recovery
for hot water heating when connected to a home water
heater. The amount of annual hot water supplied and thus
additional energy cost savings will depend on the amount
of hot water usage and the number of hours the heat pump
operates. This pump kit is suitable for potable water.
INSTALLATION
1. Follow all local, state, and national codes applicable to
the installation of the pump module kit.
2. Follow the installation instructions received with the
GVDM-26 pump module kit.
3. Connect the water lines between the unit, pump module
kit, and the water heater.
4. Pump power is 115V-60Hz 1-phase. A 6-foot, 3-prong
cord is supplied. Pump control is accomplished by 18
gauge 3-wire connection (field-supplied) from Pump
Module to the GV Heat Pump 24V terminal strip.
NOTE: The GVDM-26 Pump Module can be installed on
adjacent surface or nearer to hot water storage
tank if that easier facilitates the plumbing or
electrical connection.
