MasterCare hygiene products are designed and manufactured to help provide a more operationally efficient and secure
environment for your staff and residents. It is required that a scheduled maintenance program be set up to insure that
the efficiencies and security designed into the bathing system are kept at peak levels. Instructions on how to set up a
scheduled maintenance program are covered in this manual.
Maintenance Instructions:
MasterCare Bathing Systems are purposely designed to minimize the maintenance requirements associated with such
products. They are manufactured using materials suited to their application and the durability requirements of the health
care industry
Daily:
•Check for loose fasteners, worn seat belts and pads, leaks on the floor and mixing valve temperature.
Weekly:
•Test for proper operation of the GFCI.
Monthly:
•Door assembly: Check all components on the entire door assembly to ensure they are properly secured and not
missing. Check the security belt and pads for signs of excessive wear. Correct all deficiencies found during the
inspections before putting unit back into service.
Quarterly:
•Door assembly: Same as monthly.
•Plumbing and drain assembly: Check all fittings and connections to make sure they are secure and no leaks have
developed. Check with a hand held thermometer and observe the solar thermometer of incoming water to
ensure it is accurate.
•BathAire(SM) system: Check all air supply pipes and hoses in the system so they are secure and no air leaks have
developed. Also check to make certain no water leaks have developed.
•Control system: Check all controls to ensure that they function as outlined in the operations manual.
CAUTION:All deficiencies discovered during monthly and quarterly inspections must be corrected and/or repaired
immediately. This will help prevent potential damage to the system that could occur if corrective action is not taken
and ultimately extend the life of the bathing system.
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
THROUGHLY
CAUTION: The caution heading identifies important
maintenance and operation information. Failure to
obey a caution warning may result in damage to the
Entree Bath and may void the warranty.
Failures of materials can occur due to
normal wear associated with use or misuse
over time. It is in the best interests of the
residents
, staff and the provider that
recommended safety inspections are
scheduled on a periodic basis and preventive
maintenance performed as needed.
Before performing any checks that require
inspection inside of the tub shell, trip the
GFCI circuit breaker to OFF. It is located
under the GFCI Access Panel

ENTREE BATH LEAK GUIDE
Note: Leaks can be cause by one or more of the following.
1. Foreign debris or material between seal and inner stainless steel door skin:This generally occurs right after
installation. To correct: rotate the door to access the seal area. Use a plastic spatula or similar non-metallic tool
with cloth over the end to clean any debris trapped between the seal and stainless steel door skin, or using a
wet-vac with crevasse tool, clean along the entire length of the seal with the tool directed at the area between
the seal and the stainless steel inner door skin.
2. Water overflowing above the level of the seal inside the door:A combination of full BathAire(SM) volume and/or
an active individual you are bathing can cause water to run down along the outside of the seal making it appear
the seal is leaking. To correct: reduce BathAire(SM). Adjust the fill level of the tub down to one to four inches
below the overflow. Calm the bather down.
3. The casual water drain system is not functioning:The casual water drain system is designed to drain off any
residual water or water remaining between the tub and the seal when the door is first opened. If this system is
not functioning correctly, water will run out one side or the other of the lower end of the fiberglass door cover
when the door is rotated to a full up position.
This failure can be caused by two events:
a. Check valve stuck or plugged with debris. To correct: check and clean the valve.
b. The check valve in the 2” PVC drain pipe is located too high above the level of the hose bar in the door
when the door is rotated to a full closed position. To correct: relocate the check valve in the drain pipe
to 2 ½” above the floor. Plug the hose at the previous position of the hose barb.
4. Seal not being compressed enough:The adjustment for proper seal compression is made at the factory and will
not normally require further adjustment in the field. The seal is perfectly round when the door is open. When
the door is in a full closed position, the seal should be compressed into an oval shape about one half its original
size.
If not, two things can cause this:
a. The attendant is not holding the door close switch down until the door rotation stops automatically. To
correct: make sure the attendant(s) are holding the switch down until the door rotation stops
automatically.
b. The door is out of adjustment or the seal is flattened and unable to compress further. To correct: call
MasterCare to order a new seal and replacement instructions.
5. Seal is worn out or damaged:The inner core of the seal is permanently inflated with a material called closed cell
foam and springs back to a round shape after the door opens. Three things can happen to cause the seal to fail:
a. The round shape can be altered through prolonged compression with the door fully closed for an
extended period of time. Check the shape of the seal with the door open. If it is in a very obvious oval
shape, it has been damaged by prolonged compression.
b. The seal has been damaged by a cut or gouge in its outer surface. Check for this type of damage.
c. The seal has lost its elasticity. The seal should spring back to a round shape immediately after
decompression. If not, it is worn out and it will not seal properly.
To correct any of the above situations, replace the seal.
CAUTION:DO NOT compress the seal (close the door all the way) when tub is NOT in use.
