Section 3: COOLING INSTALLATION
3.1 Precautions

Installer is responsible for supplying a dedicated sea water pump and associated plumbing. Sea
water connections on the gyro heat exchanger mate with ¾ inch (19 mm) hose.

There is no need to disconnect hose from glycol pump except to replace the pump. In this case,
provision will need to be made to catch draining glycol as plumbing is disconnected. Use caution
to avoid breaking plastic hose connections on pump casing.

An output is available from motor drive to power and automatically control seawater pump.
This pump must operate on 230 VAC single phase and consume less than 5 amps. Pumps
requiring other voltages or higher current can still be controlled by using this supply from motor
drive to trigger an installer ‐ supplied contactor but a separate source of power must be provided.

Maximum sea water pressure in heat exchanger is 20 psi (1.4 bar)

Sea water flow requirement through heat exchanger is 4 GPM (15.1 LPM) minimum and 8
GPM (30.3 LPM) maximum under all operating conditions of the boat. When sizing sea water
pump, installer should factor in losses for raw water plumbing. In addition to initial operation at
dock, new gyro installations should be checked for minimum 4 GPM (15.1 LPM) flow while
vessel is at speed and when backing down.
3.2 Adding Coolant
1) Cooling system is filled to
proper level when shipped,
with a mixture of 50% glycol
and 50% distilled water. Clear
tube between thermostatic
valve and reservoir should be
filled with green coolant
mixture. If level has dropped,
check for evidence of leaks at
all connections before adding
fluid as described below. If
coolant is at the correct level,
skip to sea water connection in
section 3.3.
