Axiom™ Horizontal and Vertical Water Source Heat Pumps (VSHE024 VSVE024 VSHE033 VSVE033 VSHE042 VSVE042 VSHE050 VSVE050 VSHE060 VSVE060): Preventive Maintenance

This procedure is for the preventive maintenance of your unit. It has been simplified and has a list of preventive suggestions that focuses on your equipment's filter.

Preventive Maintenance

Maintenance on the unit is simplified with the following preventive suggestions:

Filter maintenance must be performed to assure proper operation of the equipment.
Filters should be inspected at least every three months, and replaced when it is evident they are dirty
Filter sizing is shown in Table 45, p. 50.

! WARNING

Hazardous Voltage!

Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized.

Check the contactors and relays within the control panel at least once a year. It is good practice to check the tightness of the various wiring connections within the control panel.

A strainer (60 mesh or greater) must be used on an open loop system to keep debris from entering the unit heat exchanger and to ensure a clean system.

For units on well water, it is important to check the cleanliness of the water-to-refrigerant heat exchanger. Should it become contaminated with dirt and scaling as a result of bad water, the heat exchanger will have to be back flushed and cleaned with a chemical that will remove the scale. This service should be performed by an experienced service person.

It should be noted that the water quality should be checked periodically (See the table below).

NOTICE:

Proper Water Treatment Required!

The use of untreated or improperly treated water could result in scaling, erosion, corrosion, algae or slime.

Use the services of a qualified water treatment specialist to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

Condensate Trap

For units incorporating a negative trap design, ensure that the condensate system is primed with water at all times. Allowing a negative, pressure condensate system to run dry could cause a break in the condensate seal allowing the fan to draw water from the condensate line to spray moisture into the mechanical system. By maintaining a primed condensate trap, a seal will be created and will help prevent these complications. The condensate trap must be field installed.

Note: When maintenance is performed on this unit, care should be taken not to damage the foil face insulation surfaces. If damage occurs repair damage with foil faced tape.
