IMPORTANT SAFETY
INSTRUCTIONS
When installing and using this electrical
equipment, basic safety precautions should be
observed including the following:
READ AND FOLLOW
ALL INSTRUCTIONS
WARNING: To reduce the risk of injury, do not
permit children to use this product unless they
are closely supervised at all times.
A wire connector is provided on this unit to
connect a minimum 10AWG (5.26mm²) solid
copper conductor between this unit and any
metal equipment, metal enclosures of electrical
equipment, metal water pipe, or conduit within
5 feet (1.5m) of the unit.

GLOSSARY OF TERMINOLOGY
These are some terms and definitions to help
get you acquainted with your cold tub.
1. ACCESS PANELS
These are the skirt panels located around
all four sides of the cold tub. All of the skirt
panels are removable should service be
required. Master Spas recommends at least
2’ of access be provided around the cold tub.
Keep in mind 6’ of open space is necessary,
on the front long side, for proper heat pump
output ventilation.
2. CIRCULATION PUMP
This small, ecient pump typically runs 24
hours for ecient filtration and provides
flow for heat pump operation to cool or heat
the water.
CIRCULATION PUMP

GLOSSARY OF TERMINOLOGY CONT.
3. HEAT PUMP
This device provides heating and cooling
capabilities to cool or heat the water to
the desired temperature. The heat pump is
sometimes referred to as the chiller.
4. HEAT PUMP CONTROL PANEL
This panel is located on the outside of the heat
pump, which is located inside the cabinet and
equipment area. Turning the heat pump on or
o, setting the water temperature and other
functions can be controlled from this panel.
The digital display will give you a temperature
readout and will notify you in case of certain
operational messages or errors.
5. HEAT PUMP UNIONS
Heat Pump Unions are used to connect the
plumping to the heat pumps. These are used
to help service personnel to easily service the
heat pump.
6. SLICE VALVES (if equipped)
These valves are used to shut o water to the
heat pump and circulation pump, so the cold
tub water does not need to be drained if the
cold tub requires service (varies by model).
NOTE: Slice valves must be completely open
during normal operations.

10. SKIMMER FILTER HOUSING
This skimmer assembly provides water flow
to the circulation pump and houses the filter.
The front skimmer faceplate portion can be
removed, to allow access to the filter element.
GLOSSARY OF TERMINOLOGY CONT.
7. BALL VALVE (If equipped)
This valve is used when filling and draining your
system. Turning the handle opens and closes
the valve to allow or retrict/shut o water flow.
This must be opened when filling and draining
your cold tub. When full and operating, this
valve needs to be in the closed position to
ensure proper flow through the heat pump.
Opening this valve during filling helps prevent
the circ pump from air locking, preventing
unwarranted damage. While draining, opening
this valve allows most all water to naturally exit
the circ pump and heat pump.
8. DRAIN VALVE
The drain valve will be secured with a beaded,
reusable zip tie. It will be secured up high, on
the frame where the valve assembly is above
normal water level. After use, always re-secure
it up high, above water level to preven possible
unwarranted freeze damage.
9. CIRCULATION JETS
These jets provide the output for the
circulation pump and flow for heat pump
operation. The circulation jets also play a
crucial role in providing a cold-water immersion
experience. Water movement across the user
prevents your body warmth from creating a
warm water layer just over your skin, making the
water feel warmer than it is. By circulating water
over the user, it prevents that warmer water
layer from developing, resulting in the user
experiencing the full water set temperature.
