INSTALLATION INSTRUCTIONS
GENERAL
These units are shipped completely assembled, charged, and wired. They do not require any field installation of refrigerant tubing. Units require external power, thermostat wiring, condensate drain piping and ducting as applicable.
Size of unit for an installation should be based on a heat gain calculation made according to applicable standards. Units must also be installed in accordance with regulations of the "National Fire Protection Association" and local electrical codes. Where local regulations conflicts with the instructions in this manual, installer should adhere to local standards.
Prepare your concrete pad or steel stand based on the corresponding dimensions. Remove shipping protective covers and wooden crating and lift unit from base and place in position with suitable rubber vibration isolators.
All field installed accessories are to be installed by the customer with necessary reinforcements as required.
LOCATION OF UNIT
When selecting the location for the unit, the following points should be kept in mind:
1.Provisions for a concrete pad or steel stand base.
2.That the terrain allows for drainage away from the unit.
3.If the unit is to be roof mounted, inspect the roof for load bearing capacity. The roof should have sufficient structural strength to carry the weight of the unit.
4.Install unit on vibration isolation pads, i.e. on rubber mounting pads.
5.Availability of electric power.
6.To position the unit for unrestricted air circulation of the condenser air inlet and to prevent any possibility of air recirculation from the condenser fan discharge air (see figure on next page).
7.Check minimum clearances required for your unit, with regard to walls, or other obstructions (see figure on next page).
8.Air cooled equipment should not be installed under low structural overhangs which can cause condenser air recirculation or restriction. Observe minimum of clearance (see figure on next page).
9.Care should be taken to prevent air from other sources from entering condenser, if this air is at a high temperature.
10.Level the unit on its final location and be sure that the levelling tolerance is ±5 mm per linear meter in any direction.
CAUTION: Do not install the unit as indoor unit, install it in an open area, and unit air inlets must not be located near exhaust vents or other source of contaminated air.
