Spare
Both 12-volt outlets located next to the panel and
above the refrigerator run from the cabin lights cir-
cuit breaker.
There is a 25-amp fuse (with spare) located under the
battery switch protecting the switch panel. This fuse
handles all 12 volt appliances.
Shore Power
The Gemini shore power inlet is rated for 30 amps (24
amps continuously) and is run with 10 gauge wire.
The switches on the 110v panel are all circuit break-
ers.
The top two are linked together as the main breaker.
In the “ON” position, a green light indicates proper
operation while a red light indicates a bad connection
or possibly a badly wired marina.
Under the main breaker are circuit breakers for the
port outlets, starboard outlets, refrigerator, water
heater, and spare (usually used for air conditioning).
The 110v panel has a slide to prevent using the refrig-
erator, water heater, and air conditioner all at the
same time. Two of the three can be operated at the
same time, however, all three would require an ex-
cess of 24 amps.
The optional microwave operates on the starboard
outlet breaker.
Water
The Gemini has two translucent 30-gal tanks under
the port and starboard aft bunks. The tanks are filled
individually from the water intakes on either side of
the mainsheet track.
Only one tank is used at a time and is selected using a
'Y' valve to select water draw from either the port or
starboard tank. Turning the valve (which is mounted
on the wall in the port aft cabin) clockwise selects
the starboard tank. Turning it counter-clockwise se-
lects the port tank.
There is an electric 12-volt pump for pressure water
to each sink, the shower, and the hot water heater.
There is a dedicated pressure water switch on the 12
volt panel.
There is a foot pump in the galley to manually pump
water from the selected tank if the pressure water
pump is not on.
Important: Be sure to have the cold-water faucet
open in the galley when using the foot pump. Fail-
ure to do so can result in breakage.
Propane
In the starboard aft cockpit locker there are two, 20
lb. vertical propane tanks with overfill protection.
Only one tank can be connected to the propane sys-
tem at a time. The propane comes from the tank via a
regulator and rubber hose to a junction box. From
the rubber hose the propane can either go through
the solenoid or through the by-pass.
From the back of the junction box are 2 copper hoses
going to each appliance.
The propane monitor is switched on at the 12 volt
switch panel. The solenoid opens and closes with an
audible “click.” The solenoid requires one (1) amp
per hour to remain in the open position. With such a
relatively high power requirement, there is a by-pass
valve intended for use while sailing. To use the by-
pass, move the connection lever so that it is inline
with the bypass copper pipe and turn off the solenoid
on the propane panel.
Caution: If the boat is unattended and connected to
shore power, it is highly advisable to turn the solenoid
on along with a battery charger to avoid depleting the
batteries.
Stove
The Gemini comes standard with a two burner, broiler
and oven unit.
To operate burners on top of unit, as well as in broiler
and oven, push knobs in to override flame failure
safety cut off device. Turn to 'on' position, and apply
a flame. Hold knob in for a few seconds then set knob
to desired setting.
The oven has a thermostat. Turning the knob on the
front of the unit sets thermostat up to 480º.
Refrigerator
The refrigerator operates on 110v (shore power) or
propane. Before lighting the refrigerator on propane
or turning on with 110v, make sure the refrigerator
vent (located under the wheel in the cockpit) is re-
moved and the 12V refrigerator fan is on. The switch
for the fan is inside the shelf unit at the side of the
refrigerator. Be sure to turn on the “Refrigerator”
switch on the 12v panel.
The refrigerator operates automatically when con-
