Electrical System
The electrical system does not require general maintenance. The following wiring diagram is supplied for
reference only.
ELECTRICAL SPECIFICATIONS OF MCP44 COOLERS
MCP44
Fan Motor: 120 V; 2.8 Amps
Main Pump: 120 V; 0 .9 Amps
If Optional PURGE PUMP is installed
Additional 0.9 Amps
Plug-In Thermostat Usage
The MCP44 can be controlled by a plug-in programmable thermostat. These thermostats are locally available,
and enable precise timing and temperature control via an electronic thermostat that plugs into a 110 volt outlet.
To use such a device with the MCP44, follow the instructions for the specific thermostat and plug the cooler into
the outlet on the thermostat.
Optional Purge Pump
In addition to the standard water pump to recirculate water from the reservoir, a purge pump can be installed to
evacuate the contents of the reservoir every 6 hours. This helps retard bacterial growth and mineral buildup on
the media, extending its life. It also maintains fresher air in the home. The use of the purge pump is actually
more economical to use than a continual bleed line. The purge pump kit (P/N MCP44-PPK) for this unit may be
purchased locally or online.
Purge Pump Discharge
NOTE:
The water ejected at the time of purging will be expelled at a high rate of speed, and must be routed
away from the foundation of the home or other areas where rushing water could do damage.
1.
Attach a standard water hose to the overflow drain to direct the water away from the house.
NOTE
: This water is not potable, but can be used for watering vegetable or flower gardens.
