Spa Care And Maintenance; Drain & Refill Instructions; Prevention Of Freezing; Winterizing Your Spa - HotSpring Grandee NXT Owner's Manual

pa are and
Your HOT SPRING spa is manufactured from the highest quality, most
durable materials available. Even so, the spa care and maintenance
program you develop will ultimately determine how long your spa, and
its individual components, will last. Regular maintenance and following
the advice in this section will help you to protect your investment.
DRAIN & REFILL INSTRUCTIONS
IMPORTANT: It is NOT recommended to refill your spa when the
ambient temperature goes below 50° F (10° C).
1. Disconnect the spa from the power supply by tripping both of the
GFCI breakers located in the subpanel.
2. Locate the main drain valve (below front panel) for the spa and
remove the drain cap. Attach the inlet of a garden hose to the drain
valve (to avoid flooding of the foundation surrounding the spa) and
route the outlet of the hose to an appropriate draining area. Spa water
with a high sanitizer level may harm plants and grass.
3. Open the valve by turning the knob. The spa will drain by gravitational
flow.
IMPORTANT: All HOT SPRING spa models will drain almost
completely through the main drain valve and the secondary drain.
Equipment such as the jet pump and heating system will drain. Any
water remaining within the plumbing or equipment after draining will
only need to be removed if the spa is being winterized.
4. Allow most of the water to drain through the main drain.
5. Remove threaded cap from secondary drain. This will drain the
remaining water (about one gallon) from the bleedline system.
6. When empty, inspect the spa shell and clean as required. (Follow the
Care of the Exterior instructions.)
7. Close the drain valve and reinstall the drain cap.
8. Reinstall threaded cap onto secondary drain.
9. Install new filters or clean existing with FRESHWATER Filter cleaner.
IMPORTANT: Always clean and rotate the filter cartridges each time
the spa is drained for cleaning.
10. Refill the spa through the filter compartment using the CLEAN
SCREEN pre-filter.
IMPORTANT: Refill water temperature must be between 50° - 70°F to
avoid high-limit tripping.
11. Follow the Quick Start-Up instructions in the Getting Started section.
COLD WATER REFILL
• When refilling your spa if the tap water is below 50° F (10° C) the
spa may go into a High Limit Protection mode (causing your spa to
stop functioning). If high limit tripping does occur, the fastest way to
reactivate the spa control system is to first disconnect power to the
spa completely, then warm the two sensors on top of the heater and
the vinyl tubing (located in the
equipment compartment) with a
hair dryer for approximately 10
minutes. Once you believe
the sensors and heater tubing
have been warmed sufficiently,
reconnect power to the spa.

• Blending warm water with the cold tap water so it exceeds 50° F
(10° C) during the refilling process will also achieve the same results if
that is an option for you.

PREVENTION OF FREEZING

Your spa has been designed and engineered for year-round use in
any climate. In some areas, extremely cold temperatures below 10°F
(-12°C) combined with strong wind, may cause partial freezing of the
jet pump, even though the water inside the spa remains at the selected
temperature. The energy efficiency of the spa may also decrease
during these cold periods, as the heater will cycle more frequently.
As an additional precaution against partial freezing of some of the
components, the equipment compartment can be insulated with an
insulating kit (available from your local dealer part# 31399). This
insulating kit will also help to maximize the spa's energy efficiency.
IMPORTANT: When warmer weather returns approx. 60°-70°F (15° -
21°C), the insulating kit must be removed to prevent overheating of the
jet pump.

WINTERIZING YOUR SPA

If you leave the spa unused for a long period of time in severely cold
weather, you should drain the spa and winterize it to avoid accidental
freezing due to a power or equipment failure.
DANGER: Use only Propylene Glycol as your anti-freeze (available
at most RV or marine supply stores). This is non-toxic. Never use an
automobile anti-freeze (Ethylene Glycol) since it is toxic!
Warning: Failure to follow these instructions correctly can lead to freeze
damage not covered by warranty. It is strongly recommended that you
contact your local dealer to perform this service
1. Drain your spa following the Drain & Refill instructions steps 1-8. Open
the waterfall valve.
2. Remove the filter cartridges, clean and store in a dry place.
3. Remove wireless remote from spa and store in a dry warm place.
IMPORTANT: These additional instructions must be utilized when
draining and winterizing your spa in climates where the temperature falls
below 32°F (0°C). A five (5) gallon combination (vacuum/blower) wet/dry
shop vac must be used to effectively remove water that is trapped inside
the plumbing lines.
4. Attach the vacuum's hose to the blower side of the shop vac.
a) Remove the filter standpipes by turning them counterclockwise.
(The standpipes may have a silicone sealant temporarily holding
them in place and it may take firm pressure to get them to initially
break free.)
b) Place the end of the vacuum hose in one of the filter openings and
cover the closest filter opening with a clean rag.
c) Turn on the blower function and allow it to blow out any water
remaining in the plumbing lines (approximately 3 to 5 minutes).
d) Turn the SMARTJET lever to the second position and allow that
system to purge.
e) If your spa is equipped with more than two jet systems, then each jet
system will also need to be blown out.
5. Attach the vacuum hose to the vacuum side of the shop vac. Vacuum
all openings and orifices as follows:
a) Jet openings: start with the jets at the top and move downward (if
suction is coming from another jet, block off the other jet using a
large rag – this will help pull out the water that is trapped deeper
inside the main line).
