Do not install, operate, or maintain this equipment before carefully reading the instruction manual.
Additional copies of this manual are available from the installing dealer or from Hydro-Temp™ Corporation.
Save these and any other operating instructions for yourself and any future owners of this equipment.
1.0 Transportation & Storage
Move and store units in an upright position. Do not stack units.
Inspect shipment for shipping damage and check packing slip for accuracy. Any equipment or cartons in
question should be removed from the packing and physically inspected. If any damage is detected, the
carrier should make a note on the delivery slip acknowledging the damage.
During freezing conditions special consideration should be made to prevent unit damage. If a unit is
taken to the job site or put in storage, anti-freeze will need to be pumped into the water coils to
prevent freezing. Failure to do this will void warranty.
2.0 Electrical Hazard Warnings
THE FOLLOWING IS A GENERAL WARNING STATEMENT WHICH SHOULD BE READ AND
UNDERSTOOD BEFORE OPERATING YOUR NEWHYDRO-TEMP™ UNIT.
There are noend user maintenance items inside the cabinet of the unit. If the unit operates unusually or
develops a leak, turn off all electrical power to unit and call your service technician.
ELECTRIC SHOCK CAN KILL!!
•Always protect yourself and others. Always turn off system power before removing panels. Some units
may have more than one or two power supplies.
•Keep all covers and panels in place at all times. Do not open panel/doors. Removing panel/doors present
an Electric shock and/or pinch hazard.
•Do not stick hands into return or any other opening.
•All repairs, electrical or mechanical, should be attempted only by trained Hydro-Temp™ technicians. In
the event of a unit problem, do not reset the equipment before correcting the problem. Equipment failure
due to resetting without first correcting the problem will not be covered by the warranty.
•The presence of water around the base of the unit constitutes an electrical hazard. Turn off the power to
the unit as soon as water leakage is discovered and call a service technician immediately.

3.0 Preventative Maintenance
YOUR HYDRO-TEMP™WATER SOURCE HEAT PUMP HAS BEEN BUILT TO BE VIRTUALLY
MAINTENANCE FREE IF PROPERLY MAINTAINED. THERE ARE ONLY A FEW THINGS YOU NEED TO
DO TO KEEP YOUR SYSTEM RUNNING AS EFFICIENTLY AS POSSIBLE.
IT’S STRONGLY RECCOMMENDED TO HAVE THE SYSTEM CHECKED ONCE A YEAR BY A TRAINED
SERVICE PROFESSIONAL. MANY INSTALLING DEALERS OFFER PREVENTATIVE MAINTENANCE
CHECKS.
WARNING! BEFORE PERFORMING SERVICE OR MAINTENANCE ON THE SYSTEM, TURN OFF ALL
BREAKERS INCLUDING MAIN POWER AND POWER TO OPTIONAL AUXILIARY HEATER. WAIT FIVE
MINUTES BEFORE REMOVING ANY PANELS TO ALLOW POWER TO DISSIPATE FROM VARIABLE
FREQUENCY DRIVES. ELECTRICAL SHOCK CAN CAUSE PERSONAL INJURY OR DEATH.
DO NOT OPEN PANELS/DOORS! DANGER OF ELECTRICAL SHOCK AND/OR PINCH HAZARD!
•Give the unit an occasional visual check. Look for water around the base of the unit and listen for any
unusual noises.
•Closed loop systems are a sealed system unless an auto purge tank is used. If totally sealed they require
no physical maintenance short of visual inspection for leaks. If your system was installed with an auto
purge tank / kit it is recommended to check the fluid level in the tank once a month when you replace the
air filter. Ensure the fluid level in the tank is between ½ and ¾ of the way full. It should be rare to have to
add fluid after the first year. If you are required to add fluid more than a few times after the first year
contact the installing dealer to have the anti-freeze levels checked.Never fill more than ¾ of the way full to
prevent over flow.
IMPORTANT NOTICE: UNITS THAT UTILIZE GROUND LOOPS OR CHILLED WATER LOOPS
MUST MAINTAIN A MINIMUM OF 20% METHANOL OR 25% PROPYLENE GLYCOL
ASANANTIFREEZE SOLUTION IN THE UNIT AND GROUND LOOP AT ALL TIMES. FAILURE TO DO SO
WILL ALLOW REFRIGERANT TEMPERATURES TO DROP, CAUSING INTERNAL FREEZING OF THE
UNIT TO OCCUR, CAUSING SEVERE DAMAGE TO THE UNIT. DAMAGE TO THE UNIT CAUSED BY
FAILURE TO MAINTAIN PROPER ANTIFREEZE LEVELS ISNOT COVERED UNDER WARRANTY.
•Open loop systems require well water to be pumped through the system. For this reason Hydro-Temp
recommends the installing dealer to install isolation valves and a water strainer on the entering water line
feeding water to the Hydro-Temp system. Be aware of the location of these components in the event the
strainer needs to be cleaned more often than once a year during your preventive maintenance check. Be
aware of all isolation valves so cleaning can be done with minimal water spillage. It’s a good idea to be
familiar with the location of the isolation valves in the event of a major waterleak. All open loop systems
have a discharge water line that discharges the water to a discharge well, creek, pond, etc. Check local
state and county codes for proper discharge of water. Be aware of discharge location and check
occasionally to insure proper drainage is occurring. During the winter, insure discharge is protected from
freezing. Do not attach any kind of sprinkler to the end of the discharge water line as the increase in back
pressure will result in decreased water flow and damage the Hydro-Temp system.
•Most systems are now equipped with controllers that allow for a system lock out feature. If the system trips
a protective limit switch 3 consecutive times the system will lockout. If the system locks out power will
need to be cycled to reset the lockout. Before resetting the lockout you must always insure the problem
causing the lockout has been repaired. If unsure consult your installing dealer before resetting the lockout.
•Be aware of all breaker locations. Some systems may have two breakers for the compressor section.
ADDITIONAL REMINDERS:
Chemicals, cleaners, inhibitors or other products that corrode or attack copper (such as Trisodium Phosphate)
should never be placed into the water circulation loop(s) connected to the Hydro-Temp equipment or stored in
the same room as the Hydro-Temp equipment. Failure to follow this requirement will void the equipment
warranty.

Customer Manual 5.2.3

Protect the Hydro-Temp™ unit from freezing temperatures. If the system is in your attic or outside special
precautions may need to be taken to ensure freeze protection.
The Hydro-Temp™ unit should never be exposed to a dirty or dusty air environment. Dust, such as sawdust or
sheet rock dust, can damage the electrical components. Simply place a cover (tarp, etc.) over the unit when
construction or any other dust producing job is being done in the area of the Hydro-Temp™ unit.
•If the unit is ever moved from its original location, never lay it on its side. Never jar or drop the unit during
transport. This is a sealed refrigeration system; rough handling may cause the system to develop a leak.
Once removed, protect the system from freezing. Anti-freeze may need to be flushed into the plumbing.
When being reinstalled, anti-freeze levels will need to be checked.
•All plumbing from the Hydro-Temp system to the hot water tank may require a licensed plumber. If any
repairs are ever needed, insure all plumbing is done / maintained with copper tubing only. Do not use
PVC, CPVC, PEX or any other plastic pipe.
•Keep an accurate service record. Keep a copy of all service reports with this booklet.
4.0 Controls and Touch Screen Display
On systems with controllers a master switch is located on the front right
corner of the unit. The purpose of the switch is to disable the
unit from running without turning off the power. Caution MUST
be taken when opening the unit for service work as the master
switch does not disconnect power. The unit is still powered with the
master switch off. This switch is useful when needing to shut down the
system for filter replacement or system operation is not needed but
thermostats are to remain powered.
4.1 Thermostat / Tank sensor
Most water to water systems do not require a thermostat like you are
accustom to seeing mounted on the wall. These systems will have a
sensor that gets mounted on the tank / buffer tank. It’s very important to
insure the sensor is making good contact with the surface of the tank.
It’s also a good idea to insure the sensor will not come loose by putting
some sort of sealant on the sensor then covering the sensor with
insulation. Inspect the sensor periodically to insure good surface contact, if the sensor comes loose damage
could be caused to the system.
4.1.2Protostar Equipment Touch Display / Monitoring System (Option)
The Protostar touch screen display is custom programmed to fit the needs of the
hot water heating system. The Equipment Touch will provide real time system
information. It will include navigation buttons to access graphics and text
screens that show real time readings from the system including safety switch
status, compressor status, etc. Password protected factory screens are also
created to edit factory settings if needed.
