8.ii Location
• Locate the Water Heater as close to the power supply as possible.
• Locate the heater in a dry location away from the bilge area and standing water.
• Do not install the Water Heater on its side or upside down.
8.iii Mounting Instructions
• Mount this product on a flat, horizontal surface only.
Step 1 Secure mounting brackets to structure with eight #12 minimum screws or ¼” (6.3mm) screws and nuts (See
figure 1.). The minimum mounting surface depth is ½” (12.5mm).
Step 2 Connect the cold water supply and hot water outlet to heater (see figure 2) using ½” N.P.T. fittings or
WX1514 / WX1524B for a Whale
® Quick Connect system.
NOTE: Whale
® recommends the use of a metal Braided Hose Connector on the hot outlet for connection to standard
flexible pipework.
Step 3 The Temperature and Pressure Relief Valve (provided with tubing) must be oriented so that discharge can exit
no more than 6” (152.3mm) above, or at any distance below the structural floor. This must not be in contact
with any live electrical part.
The Temperature and Pressure Relief Valve is factory installed. The pressure relief limits the pressure to 75 psi
(5 bar) +/- 10% and the temperature to 210ºF / 99ºC +/- 10%. For replacement parts see Maintenance
(Section 10) or contact Whale
® Support.
