COMPENSATOR TANK FUNCTION
COOLING MODE:
In the cooling mode the state of the R-22 flowing through the
center tube (7/8") is hot superheated discharge gas. The R-
22 liquid in the tank is at a lower temperature than the super-
heated gas as it has been through the condensing coil and
has had heat removed. The higher temperature of the dis-
charge gas drives the liquid out of the cavity and into circula-
tion in the system.
HEATING MODE:
In the heating mode the state of the R-22 flowing through the
center tube (7/8") is cool superheated suction gas. The R-22
liquid in the tank is at a higher temperature than the suction
gas passing through the center tube. This cooler temperature
pulls the liquid into the tank cavity and out of circulation within
the system. (All R-22 likes a nice cool place to rest.)
The net effect is that in cooling mode, the system is using the
whole R-22 charge as marked on the rating plate. In heating
mode, the system is using 1.5 to 3 lbs. less charge depend-
ing upon the size of the tank. Giving optimized system perfor-
mance for both cooling and heating.
OPTIONAL OUTDOOR THERMOSTAT
The function of the outdoor thermostat kit is to prevent unnec-
essary use of auxiliary electric heat. At temperature above
the setting of the outdoor thermostat, the electric heat is
locked out and all of the heat is provided by the heat pump.
The setting or the outdoor thermostat is important and is ide-
ally selected at the home “balance point”, when the heat
pump capacity is equal to the heat loss of the home. See
instructions packed with these kits.
NOTE:
All installations of this heat pump in Manu-
factured Homes built per HUD standards
SHALL have an outdoor thermostat
installed at the time of installation by the
installer. In accordance with HUD std.
3280.714 (a) (1) (ii). Outdoor thermostat,
Part number 3024-6881/D shall be used and
should be ordered at your nearest UPG
