Zen Hot Tubs Startup
 Selecting Zen Hot Tubs Site Location
It is important your new spa be installed on a solid, flat, and level surface that is engineered to
carry a load of 75 pounds per square foot. Spas should not be placed near or below electrical or
telephone cables. If there is not a dedicated 120v receptacle within 10’ of your spa, contact a
Licensed Electrician to supply power near the spa. A GFCI Power Cord is supplied with all 120v
applications.
 Filling Your Spa
Unthread and remove the filter. Put garden hose in the void where the filter was. This will help to
eliminate air locks. With the electrical breaker in the OFF position and/or the power cord un-
plugged, fill to an approximate water level of 2" above the top of the highest jet.
 Relieving Air Locks
Occasionally, on a fresh fill or refill, an air lock may occur. This is caused by the build up of air in
the plumbing lines which will not allow water or air to flow through the jets. If left un-attended, the
pump can overheat from lack of water flow. This type of damage is not covered under the
warranty. The easiest way to remedy this situation is to repeatedly cycle between high-speed and
off on the topside controls. If this does not fix the issue you will have to open the vented access
panel that houses the pump. Once the panel is removed, locate the pump and you will see two
large, white nuts attached to the pump. One is horizontal to the pump and the other is vertical. Take
a large pair of channel locks and loosen the horizontal nut with the pump in high-speed. Continue
to loosen the nut until the jets begin to work. Doing this will cause water to come out the nut you
are loosening which is normal. Once the jets are functioning properly, tighten the nut back up and
put the panel back on.
 Air Adjustment
To introduce air into the jets, turn the air controls (located on the spa's top edge) counterclockwise.
To decrease air flow, turn the air controls clockwise.
 Suction Fitting
Keep the suction fitting (located in the foot well area) of the spa unobstructed and free from debris
at all times. Only remove the suction-fitting screen for cleaning. Never remove it while the spa is
connected to electrical power.
